Crosstar 21Pcs M35 Cobalt Drill Bit Set,1/16"-1/2" Metal Drill Bits
- 【Engineered for Thin, Hard & Gummy Metals】 This set is specifically engineered for the unique challenges of drilling thin sheet metal (e.g., stainless steel, titanium). Thin, hard materials are prone to causing bits to skate, work-harden, and overheat rapidly, leading to premature dulling. The M35 cobalt steel core provides exceptional hot hardness to resist edge softening under intense localized heat, while the geometry is optimized to cut cleanly without excessive force that can distort thin material.
- 【Start Straight, Drill Fast, Finish Clean】 Featuring a self-centering Pilot Point tip, these bits eliminate frustrating "bit walk" on curved or hard surfaces for perfectly placed holes. Combined with a 135° split point, this design allows for faster penetration with significantly less downforce, resulting in cleaner holes with minimal exit burrs. This ensures precise, professional results in sheet metal with reduced post-processing time.
- 【 TiAlN Coating: Extreme Heat Resistance for Longer Life】 The critical performance differentiator is the TiAlN (Titanium Aluminum Nitride) nano-coating. It withstands continuous friction temperatures exceeding 1,472°F (~800°C), forming a protective barrier that drastically reduces wear. This translates directly to a multi-fold increase in usable life compared to uncoated or standard TiN-coated bits, maintaining a sharp cutting edge through demanding jobs and lowering the long-term cost.
- 【 Professional 21-Piece Kit with Smart Organization】 Includes the 16 most essential sizes from 1/16" to 1/2", with practical duplicates provided for the 5 smallest, high-wear diameters. Every bit is securely held in a robust, compartmentalized storage case featuring laser-etched size labels. This system ensures instant identification, superior protection against damage, and perfect portability for shop or site.
- 【Pro-Tip for Optimal Results & Guaranteed Satisfaction】 For best performance on thin metals: Apply firm, steady, and vertical pressure at startup to engage the Pilot Point and prevent skating. We stand behind this set with a 90-Day Satisfaction Guarantee. Contact our customer support directly with any concerns for a prompt and satisfactory resolution.*Note:Bits ranging from 1/16" to 1/8" adopt a standard tip design, whereas those sized from 9/64" to 1/2" feature a bullet tip design*.
