Description

The 11.5mm Cobalt RED HELIX™ Twist Drill Bit is built for maximum strength and consistent performance when drilling into hard metals. Its variable helix design, featuring a 35° aggressive lead that transitions to 15°, promotes fast chip evacuation, reduces heat buildup, and keeps the cutting edges sharp longer. The QUAD EDGE 135° split-point tip delivers accurate starts without wandering, allowing for faster, cleaner hole creation. With four precision cutting edges, this bit produces smaller chips for smoother drilling and extended tool life. An enhanced internal web taper increases overall bit strength to help prevent breakage, while the cobalt construction provides exceptional durability—offering up to 10 times longer life compared to black oxide drill bits. Ideal for demanding professional drilling applications.
