Kit Includes: 21 Cobalt Drill Bits (1/16"x2, 5/64"x2, 3/32"x2, 7/64"x2, 1/8"x2, 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 15/64", 1/4", 5/16", 3/8", 1/2") in rugged indexed case. 🛠️【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. Meet Your Ultimate Metal-Drilling Partner Tired of snapping bits on stainless steel? The Crosstar Pro Series harnesses aerospace-grade M35 cobalt steel and TiAlN nano-coating to chew through hardened metal like butter. Our triple-flute geometry – inspired by CNC end mills – evacuates chips 3X faster than standard bits, keeping temperatures low and precision high. Whether you're fabricating automotive parts or installing stainless fixtures, this 21-piece arsenal delivers surgical accuracy without the chatter. Why Machinists Choose Crosstar: Coolant-Free Operation: TiAlN coating reduces friction by 70%, even at red-hot temps. Kit Includes: 21 Cobalt Drill Bits (1/16"x2, 5/64"x2, 3/32"x2, 7/64"x2, 1/8"x2, 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 15/64", 1/4", 5/16", 3/8", 1/2") in rugged indexed case. 🔥 【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.* Condition: New.
