Cleveland C16772 Taper Length Drill Bit Wire 49 Cobalt

Product Description

The CLEVELAND C16772 is a taper length cobalt drill bit designed for demanding drilling applications across a wide range of materials. Built to M42 cobalt steel standards, it features a 135-degree split point that reduces walking and lowers the thrust required to start a hole without a center punch. The parabolic flute geometry improves chip evacuation, which is especially important when drilling deep holes or working in gummy materials like stainless steel and nickel alloys. At 3.75 inches overall length with a 2.0 inch flute, this bit provides reach beyond a standard jobber while remaining manageable in a hand drill or drill press setup.

This bit is suited for production drilling in metal fabrication, machine shops, and maintenance environments. It handles a broad material range including aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. The straight shank and wire gauge sizing make it a practical choice for use in standard drill chucks without adapters. It is packaged individually and sold as a single unit, making it easy to replace a worn bit without purchasing a full set.

Key Features

• Wire size 49 (0.0730 inch decimal equivalent) for precision small-diameter drilling
• 135-degree split point reduces thrust and eliminates walking on flat surfaces
• Parabolic flute design improves chip evacuation in deep-hole and gummy-material applications
• M42 cobalt construction provides heat and wear resistance for heavy-duty use
• Web-thinned, tapered web configuration reduces cutting resistance
• Meets ASME B94.11M and DIN 340 standards; conforms to DIN 338 specification

Compatibility

Designed as an OEM-style taper length replacement drill bit for use in standard straight-shank drill chucks across drill press, hand drill, and CNC drilling applications requiring wire gauge sizing.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.
