Cleveland C11433 Cobalt Jobber Drill Bit Wire 33 Tialn

Product Description

The CLEVELAND C11433 is a cobalt jobber length drill bit designed for demanding metal drilling applications. Made from M42 cobalt high-speed steel and finished with a TiAlN coating, it delivers extended tool life when cutting hard and abrasive materials. The 135-degree split point reduces walking and thrust at entry, allowing clean, accurate hole starts without a center punch. At 2.625 inches overall length with a 1.5-inch flute, this is a standard jobber-length geometry suited to drill presses, hand drills, and CNC setups. Machinists, maintenance technicians, and industrial tradespeople rely on this drill for production and repair work in ferrous metals and stainless steel.

This drill bit is sized to wire gauge Number 33, with a decimal diameter of 0.1130 inches. It fits applications requiring precise small-diameter holes in hardened or tough materials, including stainless steel, alloy steel, cast iron, and titanium. The straight-cylindrical shank mates with standard drill chucks. The parabolic flute design improves chip evacuation in deep holes, reducing recutting and heat buildup. It is well-suited for production drilling, toolroom work, and field maintenance where tool longevity and hole accuracy matter.

Key Features

• M42 cobalt steel construction for heat resistance and durability in hard metals
• TiAlN coating reduces friction and extends tool life in abrasive materials
• 135-degree split point for reduced thrust and self-centering entry
• Parabolic flute geometry promotes efficient chip evacuation in deep holes
• Web-thinned, tapered web configuration reduces cutting resistance
• Right-hand cut with straight-cylindrical shank for standard chuck compatibility

Compatibility

Designed as a standard jobber-length drill bit with a straight-cylindrical shank compatible with any drill press, hand drill, or CNC spindle chuck sized for 0.1130-inch shank diameters. Meets ANSI specification requirements for jobber-length geometry.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling. Use cutting fluid or coolant appropriate for the workpiece material to manage heat, particularly in stainless and alloy steels. Ensure the workpiece is firmly clamped to prevent walking or chatter on entry. Inspect the cutting edges before each use and replace the bit if chipping or wear is visible to maintain hole tolerance.
