3016032 Cobalt Jobber Drill Bit, 1/2 In Dia, 3-1/4 In OAL

The Irwin 3016032 Cobalt Jobber Drill Bit is a high-performance drilling solution engineered for metal drilling applications, especially when working with hardened steel and abrasive alloy materials. This jobber-length bit combines cobalt-infused steel with precision engineering to deliver clean, accurate holes in demanding metal-working projects.

Whether you're a professional contractor or a serious DIY enthusiast, this drill bit reduces the frustration of bit walk and provides the heat resistance needed for extended use. The split point design allows drilling to begin immediately without wandering, while the cobalt content keeps the bit sharp even under the high temperatures generated during heavy-duty drilling on tough metals.

Features and Benefits

• 5% Cobalt Steel Construction: Superior heat and abrasion resistance ensures the bit stays sharp longer when drilling hardened steel, alloys, titanium, and stainless steel.
• Split Point Geometry: The split point tip begins drilling immediately, significantly reducing bit walk and improving hole accuracy in metal applications.
• Heavy-Duty Web Design: Robust web construction provides enhanced strength and durability, supporting consistent performance even in demanding drilling tasks.
• Lower Torque Entry: Reduced torque upon entry makes penetrating high-tensile strength materials easier and reduces strain on both the drill and operator.
• Optimized Chip Ejection: Spiral flute design promotes faster chip removal, improving drilling efficiency and extending bit life.
