Best Irwin Tools Drill Bits in 2026

HSS Titanium Coating - Classic HSS construction with titanium coating for capability and durability. The cutting edge is hardened and honed for sharpness, chatter-free design with staggered cutting teeth ensure the precise countersinking and hole smooth clean.

Flutes Form - 2 flutes form helps clear chips and debris away from the bit, decreasing friction and heat for a faster, cooler drilling process.

Quick Change - 1/4 inch hex shank fits into all power tools more easily and securely, specially for locking into quick change chuck.

Ideal for drilling in tough metal, including heavy-duty abrasive alloy metal drilling on hardened steel

Made from industrial grade High-Speed Steel for increased durability. 8% Cobalt alloy steel is heat and abrasion-resistant

135-degree split-point tip starts drilling immediately with less force and eliminates "walking" across the work surface
