IRWIN 63128 DRL 7/16 COB JL 135′ BULK

Engineered for outstanding performance in demanding drilling applications, this set of cobalt alloy drill bits features a heavy-duty spiral flute design that enhances chip ejection for efficient cutting. Made from M-35 5% cobalt alloy high-speed steel, these bits offer superior resistance to abrasion, making them ideal for tackling tough metals with ease. The innovative 135-degree split point design minimizes feed pressure, facilitating smoother penetration without the risk of work hardening, while the shorter cutting lips effectively reduce torque, allowing for efficient drilling in high tensile strength materials. This pack of six ensures you have the right tools at hand for all your heavy-duty drilling needs.
