3016025 Cobalt Jobber Drill Bit, 25/64-In.

The Irwin 3016025 Cobalt Jobber Drill Bit is a 25/64-inch diameter bit designed for drilling through tough metals including hardened steel, cast iron, and stainless steel. The 5% cobalt composition and heavy-duty web construction provide higher heat and abrasion resistance, while the 135-degree split-point tip minimizes bit walk for accurate hole placement from the first contact with the workpiece.

This jobber length drill bit is ideal for metal fabrication, automotive repair, and construction applications where precision and efficiency matter. The split-point design begins cutting immediately, reducing the tendency for the bit to wander or skate across the work surface. The reduced shank provides a stable grip in your drill chuck and reduces vibration during operation, helping you achieve cleaner, more precise holes even in abrasive alloy metals.
