The Red Helix design features a variable helix flute geometry that optimizes chip removal and drilling speed. The aggressive 35° cutting edge transitions to 15°, creating a more efficient cutting action. Combined with the quad edge tip, this design drills up to 3X faster than standard bits while producing smaller chips that clear more easily.

Yes, these Milwaukee Shockwave drill bits are specifically engineered for impact duty use. The 1/4" hex shank is designed for impact drivers and provides superior grip compared to round shanks. They're also compatible with standard drill drivers and any tool that accepts 1/4" hex accessories.

The 135° split point tip is a self-centering design that prevents the bit from walking or skating across smooth surfaces when you start drilling. This is especially important when drilling pilot holes in fascia boards or other smooth materials where precision is critical. It allows you to drill accurately even when working one-handed on a ladder.

The titanium coating significantly extends bit life compared to uncoated bits. It provides heat resistance and reduces friction during drilling, which prevents premature wear. In professional gutter installation use, contractors report these bits lasting 3-5X longer than standard high-speed steel bits, even in demanding outdoor conditions.

These bits are designed for drilling wood, plastic, and thin metal materials commonly found in gutter work. They excel at drilling pilot holes in fascia boards (wood or composite), aluminum gutters, vinyl trim, and soffit materials. For thicker metal or masonry, you'll need specialized bits designed for those materials.

Having two identical bits provides a backup on the job site, which is essential for professional contractors. If one bit becomes dull or breaks during a project, you have an immediate replacement without needing to stop work. The 1/8" size is one of the most commonly used for pilot holes, so having a spare ensures you can complete your gutter installation without delays.
