IRWIN 63132 DRL 1/2 COB JL 135′ BULK

Crafted from M-35 cobalt alloy steel, these jobber-length drill bits offer exceptional durability and performance, especially in tough metal applications. Featuring a 135-degree split point, they efficiently penetrate materials with reduced feed pressure, helping to minimize work hardening. The heavy-duty spiral flute design enhances chip ejection, allowing for smoother drilling processes, while the shorter cutting lips work to reduce torque, making these bits ideal for high tensile strength materials. Perfect for professionals and serious DIY enthusiasts alike, this pack of six ensures you have reliable tools on hand for any drilling task.
