IVY Classic 4-Inch Bi-Metal Reciprocating Saw Blade — 14 TPI

Precision Metal Cutting for Aluminum Gutters, Downspouts, and Sheet Metal — Smooth 14 TPI Finish

Gutter installation contractors require reciprocating saw blades that cut aluminum gutters, downspouts, flashing, and sheet metal cleanly without burrs, distortion, or jagged edges. Standard wood-cutting blades tear metal and leave rough edges that require additional finishing work. The IVY Classic 4-inch bi-metal reciprocating blade with 14 teeth per inch (TPI) delivers the smooth, precise cuts that metal fabrication and gutter installation demand. The 8% cobalt Matrix II cutting edge provides superior hardness (65-67 HRC) and heat resistance for extended blade life during demanding metal cutting applications. The compact 4-inch length provides excellent control in tight spaces and flush-cutting applications common in gutter installation work.

Key Benefits at a Glance

Smooth Metal Cuts

14 TPI tooth count delivers smooth, burr-free cuts in aluminum gutters, downspouts, and sheet metal — professional finish without secondary cleanup.

8% Cobalt Durability

Matrix II cobalt alloy cutting edge with 65-67 HRC hardness resists heat and wear — cuts more material per blade than standard bi-metal blades.

Compact 4-Inch Length

Short blade provides superior control in tight spaces and flush-cutting applications — ideal for gutter modification and renovation work.

Universal Saw Compatibility

Standard 1/2-inch universal shank fits all reciprocating saws — Milwaukee, DeWalt, Makita, Bosch, and all major brands without adapters.

Professional-Grade Bi-Metal Blade for Aluminum Gutter and Sheet Metal Cutting

Metal cutting with a reciprocating saw requires the right blade for the material and application. Blades with too few teeth per inch cut aggressively but leave rough, jagged edges that require deburring and finishing. The IVY Classic 4-inch bi-metal blade — also known as a metal cutting recip blade, sawzall blade, and demolition blade — features 14 teeth per inch (TPI) specifically optimized for cutting aluminum, sheet metal, and thin-wall materials in the 1/8-inch and above thickness range. This tooth count provides the ideal balance between cutting speed and edge quality for gutter installation applications where clean cuts matter.

For gutter installation contractors, the bi-metal blade is the workhorse cutting tool for daily metal fabrication. Cutting aluminum K-style and half-round gutters to length, trimming downspouts for custom runs, notching flashing for proper fit, and modifying metal components during renovation work all require a blade that cuts metal cleanly and efficiently. The 8% cobalt Matrix II cutting edge provides the hardness and heat resistance needed for repeated metal cuts without rapid tooth dulling. The electron beam welded construction bonds the hardened cutting edge to a flexible alloy-steel back, preventing blade breakage during demanding cutting applications.

The compact 4-inch blade length is specifically designed for tight-space cutting and flush-cut applications. The shorter blade provides better control and maneuverability compared to longer blades, making it ideal for gutter modification work where precision matters. The .035-inch blade thickness provides rigidity during cutting while maintaining the flexibility needed to navigate tight spaces. The universal 1/2-inch shank fits all standard reciprocating saws without adapters. GutterAll supplies professional gutter installation contractors with IVY Classic bi-metal blades and related cutting tools. Available for shipping nationwide and local pickup at our Damascus, Oregon location.

Why Gutter Installation Contractors Rely on 14 TPI Bi-Metal Blades

Every gutter installation involves metal cutting — trimming gutters to length, cutting downspouts, notching flashing, and modifying components for custom fits. The blade choice directly affects cut quality, installation speed, and professional appearance. Blades with low tooth counts (6-10 TPI) cut fast but leave rough edges that catch debris, collect dirt, and look unprofessional. The 14 TPI configuration provides the smooth, clean cuts that professional gutter work demands while maintaining adequate cutting speed for production work. The 8% cobalt construction ensures the blade maintains its cutting edge through multiple jobs, reducing blade changes and downtime. Contractors who use proper metal-cutting blades complete installations faster, deliver cleaner results, and spend less time on secondary finishing work.

Gutter Installer Applications — When 14 TPI Bi-Metal Blades Excel

The IVY Classic 4-inch 14 TPI bi-metal blade addresses five primary cutting scenarios where gutter installation contractors need smooth, precise metal cuts:

Application	The Challenge	Why It Helps
Aluminum Gutter Cutting	K-style and half-round gutters must be cut to exact lengths with clean edges for proper seaming	14 TPI provides smooth, burr-free cuts in aluminum — clean edges seal properly and look professional
Downspout Trimming	Downspouts require precise cuts for custom runs, elbows, and termination points	Compact 4-inch blade provides control for accurate cuts — smooth edges fit connectors properly
Flashing Modification	Metal flashing requires notching and trimming for proper fit around roof penetrations and transitions	Controlled cutting in tight spaces — 14 TPI cuts flashing cleanly without distortion
Sheet Metal Fabrication	Custom brackets, hangers, and components require precise metal cutting on site	Bi-metal construction handles sheet metal efficiently — cobalt edge maintains sharpness through multiple cuts
Renovation and Replacement	Removing old gutters and downspouts requires cutting through corroded or painted metal	65-67 HRC hardness cuts through aged metal — cobalt edge resists dulling on challenging materials

Contractor Insight: Experienced gutter installation contractors select blade TPI based on material thickness. For aluminum gutters and thin sheet metal (under 1/4"), 14 TPI provides the best balance of cutting speed and edge quality. Lower TPI blades (6-10) are better for thicker materials and demolition, while higher TPI blades (18-24) work best for very thin materials. Keeping multiple TPI options on the truck ensures the right blade is available for each application.

8% Cobalt Matrix II Cutting Edge — Superior Hardness and Heat Resistance

Standard bi-metal blades use high-speed steel (HSS) for the cutting edge. The IVY Classic blade upgrades to an 8% cobalt alloy that provides significantly higher hardness (65-67 HRC Rockwell) and heat resistance. Cobalt maintains its hardness at elevated temperatures that would soften standard HSS, allowing the blade to cut longer without losing its edge. This is particularly important for metal cutting where friction generates substantial heat at the cutting edge.

14 Teeth Per Inch — Optimized for Thin Metal Cutting

Tooth count (TPI) determines the balance between cutting speed and cut quality. Lower TPI cuts faster but rougher; higher TPI cuts slower but smoother. The 14 TPI configuration is specifically optimized for aluminum gutters, downspouts, and sheet metal in the 1/8-inch to 1/4-inch thickness range — the most common materials in gutter installation. This provides smooth, professional-quality cuts without sacrificing too much cutting speed.

Electron Beam Welded Construction — Strength Without Brittleness

Bi-metal blade construction joins a hardened cutting edge to a flexible alloy-steel back. The electron beam welding process creates an extremely strong bond between the two metals without the heat-affected zone that weakens conventional welding. This construction provides cutting edge hardness for durability while maintaining back flexibility to prevent blade breakage during demanding cutting applications or when the blade encounters unexpected resistance.

4-Inch Compact Length — Control in Tight Spaces

The 4-inch blade length is specifically designed for tight-space cutting, flush-cut applications, and detailed work where longer blades are difficult to control. For gutter installation, this includes cutting in confined areas near fascia boards, trimming downspouts close to walls, and making precise cuts for component fitting. The short length reduces blade flex during cutting, improving accuracy and control.

TPI Comparison — Choosing the Right Tooth Count for the Application

6-10 TPI — Aggressive Cutting

Fast cutting for thick materials and demolition. Rough edge finish requires secondary work. Best for materials over 1/4" thick.

Best for: Thick metal, wood, demolition, rough cutting

14 TPI — Precision Metal (This Product)

Smooth, clean cuts in aluminum and sheet metal. Professional edge finish. Optimized for 1/8" to 1/4" materials.

Best for: Aluminum gutters, downspouts, sheet metal, flashing

18-24 TPI — Fine Metal

Very smooth cuts for thin materials. Slower cutting speed. Best for materials under 1/8" thick or when edge quality is critical.

Best for: Thin sheet metal, tubing, conduit, detailed work

Professional Guidance: The general rule for metal cutting is that at least 3 teeth should be in contact with the material at all times. For aluminum gutters (typically .027" to .032" thick), 14 TPI provides optimal tooth engagement while maintaining smooth cutting action. This blade excels at the metal thicknesses most common in gutter installation work.

Setup and Application Guide — Using the IVY Classic 14 TPI Bi-Metal Blade

Select appropriate PPE: Metal cutting produces sharp edges, chips, and noise. Wear safety glasses, hearing protection, and work gloves. Consider long sleeves to protect arms from metal chips.
Inspect blade condition: Before installation, inspect the blade for visible damage, missing teeth, or dulling. A new blade should have uniform, sharp teeth along the cutting edge. Do not use damaged blades.
Install blade in reciprocating saw: Release the blade clamp on the reciprocating saw. Insert the 1/2-inch shank fully into the blade holder. Secure the blade clamp and verify the blade is firmly locked in position.
Mark the cut line: Using a marker, pencil, or masking tape, mark the cut line on the material. For aluminum gutters, mark on the exterior surface for visibility during cutting.
Secure the workpiece: Clamp or brace the material securely to prevent movement and vibration during cutting. For gutter cutting, support both sides of the cut to prevent the gutter from closing or twisting.
Position the saw: Position the shoe of the reciprocating saw firmly against the material surface. The shoe provides stability and controls cutting depth. Ensure the blade will not contact supports or clamps.
Start the cut at moderate speed: Begin cutting at moderate speed to establish the cut groove. Let the blade do the cutting — do not force the blade through the material. Forcing causes blade deflection and poor cut quality.
Maintain steady cutting motion: Move the saw smoothly along the cut line, maintaining contact between the shoe and material. For curved cuts, slow down and allow the blade to follow the curve without binding.
Complete the cut: Continue cutting until the blade passes completely through the material. Support the cut piece to prevent tearing or bending as the cut completes. Allow the blade to exit cleanly.
Deburr if necessary: While 14 TPI provides smooth cuts, inspect the cut edge and remove any minor burrs with a file or deburring tool if needed for proper fitting or safety.

Pro Tip: For the cleanest cuts in aluminum gutters, use cutting oil or WD-40 on the blade to reduce friction and heat buildup. This extends blade life and improves cut quality. Also, cutting with the gutter upside down (bottom facing up) often provides better visibility and support for the cut.

Frequently Asked Questions

Will this blade fit my reciprocating saw? +

Yes. The IVY Classic bi-metal blade features a universal 1/2-inch shank that fits all standard reciprocating saws. This includes Milwaukee, DeWalt, Makita, Bosch, Ridgid, Hitachi, Porter-Cable, Ryobi, and all other major brands. No adapters or modifications are needed — the blade installs directly into any standard reciprocating saw blade holder.

What is the difference between this blade and standard bi-metal blades? +

The IVY Classic blade uses an 8% cobalt Matrix II alloy for the cutting teeth instead of standard high-speed steel (HSS). Cobalt provides significantly higher hardness (65-67 HRC vs 62-64 HRC for standard HSS) and superior heat resistance. This means the blade maintains its cutting edge longer, especially during extended cutting sessions where heat buildup would dull a standard blade. Contractors typically get 2-3 times more cuts per blade compared to standard bi-metal construction.

Is 14 TPI the right choice for cutting aluminum gutters? +

Yes, 14 TPI is optimal for aluminum gutters and downspouts. The general rule for metal cutting is that at least 3 teeth should be in contact with the material during cutting. Aluminum gutters are typically .027" to .032" thick — 14 TPI provides ideal tooth engagement for this thickness while delivering smooth, burr-free cuts. Lower TPI (6-10) cuts too aggressively and leaves rough edges, while higher TPI (18-24) cuts too slowly for production work.

What is the return policy? +

IVY Classic bi-metal reciprocating blades may be returned within 30 days of purchase in original, unopened packaging for a full refund or exchange. Blades that have been used or opened cannot be returned due to safety and hygiene considerations. Contact sales@gutterall.com to initiate a return and receive return shipping instructions before sending items back. Refunds are processed within 5 to 7 business days of GutterAll receiving the returned item in qualifying condition. Return shipping costs are the responsibility of the buyer unless the return is due to a product defect or shipping error.

How long does shipping take? +

Orders are typically processed and shipped within 1 to 2 business days from GutterAll's Damascus, Oregon facility. Standard ground shipping transit time is 3 to 7 business days depending on destination. In-store pickup at 19759 SE Sunnyside Rd, Damascus, OR 97089 is available Monday through Friday 7am to 4pm and Saturday 9am to 2pm PST. Local delivery within the greater Damascus and Portland metro area is also available. Contact sales@gutterall.com or (503) 850-6784 for bulk orders and expedited shipping options.

Can this blade cut wood or other materials? +

Yes, bi-metal blades can cut wood, plastic, and other soft materials, but they are optimized for metal cutting. The 14 TPI configuration will cut wood slowly and is not efficient for wood-only applications. For general demolition involving mixed materials (wood with nails, for example), a lower TPI blade (6-10) is more appropriate. This blade excels specifically at metal cutting applications where smooth edge quality is required.

Safety Notice — Personal Protective Equipment Required

PPE REQUIRED FOR ALL METAL CUTTING OPERATIONS. Metal cutting produces sharp edges, metal chips, and noise hazards. Always wear ANSI-rated safety glasses, hearing protection, and work gloves. Long sleeves recommended to protect arms from metal chips. Cut edges may be sharp — handle freshly cut metal with gloves. Secure workpieces before cutting. Follow all reciprocating saw manufacturer safety instructions. Do not use damaged or dull blades. For product questions, contact sales@gutterall.com.
