Description
-
4-Flute Turbo-Cutting System: Engineered with advanced quad-spiral grooves, this set delivers 40% faster chip evacuation than standard 2-flute competitors. This innovative geometry virtually eliminates jams and ensures smooth, continuous drilling even in deep holes.
-
Military-Grade M35 Cobalt Core: Forged from high-performance HSS with 5% Cobalt alloy, these bits can withstand extreme heat up to 1,450°F. This provides a 3X longer lifespan compared to standard HSS bits, making them ideal for hardened steel, stainless steel, and carbon fiber composites.
-
Nano-AlTiN Armor Coating: Features a premium Aluminum Titanium Nitride (AlTiN) coating with a surface hardness of 89HRC and a ultra-low 0.45 friction coefficient. This “armor” layer far outlasts traditional TiN coatings, allowing for higher drilling speeds and superior wear resistance.
-
Universal 1/4″ Hex Shank: Designed for maximum compatibility, the anti-slip 1/4-inch hex shank fits securely into impact drivers and power drills. The specialized grooves prevent chuck slippage even under high-torque applications (up to 35N·m).
-
34 Precision Step Sizes: This 3-piece set offers a comprehensive range of 34 step sizes, covering diameters from 1/8″ to 7/8″ in precise 0.04″ increments. Perfect for precise hole enlarging in metal, plastic, and wood.
-
Pro-Grade Protection: Includes a rugged, shockproof carrying case to ensure your precision bits remain protected, organized, and ready for the most demanding job sites.
