1 Inch Drill Bit for Metal - HSS M35 Cobalt Titanium Nitride Coated, 3-Flat Shank Design for Precision Drilling in Hard Steel, Cast Iron and Thick Aluminum
Heavy-Duty M35 Cobalt Construction: Designed for the most challenging jobs, this 1-inch bit is made from high-speed M35 Cobalt steel, providing exceptional hardness and red-hardness to power through hardened steel and cast iron without failing.
Titanium Nitride Coated Edge: The gold TiN coating offers an ultra-hard, heat-resistant surface that minimizes friction and chip welding. This ensures smoother cutting action, extended bit life, and requires less effort and downforce during operation.
Maximum Grip 3-Flat Shank: The heavy-duty tri-flat shank is engineered to handle the extreme torque required for large-diameter drilling. It guarantees a secure lock in the chuck, preventing dangerous slippage and providing superior control.
Drills into Hardest Materials: Specifically built for precision drilling in thick, hard metals including tool steel, high-strength alloys, thick-walled cast iron, and heavy-duty aluminum profiles commonly used in structural and industrial applications.
Robust Design for Large Diameters: With a substantial 1-inch diameter, this bit is your go-to tool for creating large holes for conduits, pipes, shafts, and bolts in industrial maintenance, fabrication shops, and major construction projects.
