Titanium Nitride (TiN) coated drill bits provide up to 500% extended tool life compared to standard HSS bits, making them extremely cost-effective long-term. The super-hard coating reduces friction, dissipates heat better, and maintains sharp cutting edges longer. For professionals who drill regularly, the extended life and consistent performance more than justify the initial investment.

Yes, TiN coated drill bits are specifically designed for drilling hard metals including work-hardened stainless steel, hardened steel, and other difficult materials. The titanium nitride coating provides the hardness and lubricity needed to cut through these challenging materials while maintaining edge sharpness and dimensional accuracy.

Professional work demands reliability and continuity. Having multiple bits ensures you can continue working if one becomes damaged or worn, prevents project delays, and allows for different applications simultaneously. The 4-piece set also provides better value per bit compared to individual purchases, making it the smart choice for professionals.

Yes, these bits feature standard straight shanks that fit all standard drill chucks, including hand drills, cordless drills, drill presses, and milling machines. The 1/8" diameter is a common size that works with most chuck capacities. They're designed for universal compatibility with professional and consumer drilling equipment.

Replace bits when you notice increased drilling effort, rough or oversized holes, excessive heat generation, or visible wear on the cutting edges. The golden TiN coating will show wear patterns, and the bit may produce more chips or require more pressure. With proper use, these bits will significantly outlast standard HSS bits before showing these signs.

Use moderate to high speeds for softer materials like aluminum and wood, and slower speeds for harder materials like stainless steel and hardened metals. Generally, start with manufacturer recommendations and adjust based on material response. The TiN coating allows for higher speeds than standard bits while maintaining cutting performance and tool life.
