Product Details
✓🔥 【Engineered for Hardened Metals with M35 Cobalt Steel】 Crafted from premium M35 cobalt high-speed steel (5% cobalt), these bits are specifically designed to tackle the tough materials, including stainless steel, hardened cast iron, high-carbon steel, and titanium alloys, with effective drilling hardness up to 60 HRC.
✓⚡️【TiAlN Coating for Extreme Heat Resistance & Extended Life】 The Titanium Aluminum Nitride (TiAlN) nano-coating withstands cutting temperatures up to 1472°F (800°C), drastically reducing heat buildup and friction. This results in a significantly longer tool life compared to standard titanium nitride or oxide coatings.
✓🎯 【Triple-Flute Design: Smother Finish, Faster Drilling, Pinpoint Accuracy】 The innovative three-flute geometry provides three key advantages over conventional two-flute bits: superior hole roundness and wall finish, approximately 40% improved chip ejection for cooler operation, and enhanced drilling accuracy with reduced bit walk. For optimal performance, recommended for standard depth of cut applications.
✓🛠️【Three-Flat Shank for Maximum Grip & Zero Slip】 The precision-machined three-flat shank ensures a complete lock in the drill chuck, eliminating spin-out even under high-torque conditions from impact drivers and heavy-duty drills. This guarantees full power transfer and safer operation.
✓📦 【Comprehensive 21-Piece Professional Set】 This ready-to-use set includes 21 essential sizes from fine 1/16" to heavy-duty 1/2", covering over 90% of common metal drilling tasks. *Note: Bits 1/16" through 7/64" feature a precision two-flute design for delicate work, while sizes 3/32" and up utilize the performance triple-flute design.*
