Cleveland C16805 Taper Length Cobalt Drill Bit 1.5mm

Product Description

The CLEVELAND C16805 is a taper length cobalt drill bit designed for demanding material removal in professional machining and fabrication environments. Built to Series 2575 specifications, this bit features a 1.5 mm diameter, a 135-degree split point for reduced walking and faster penetration, and a parabolic flute geometry that clears chips aggressively. The cobalt construction provides elevated heat resistance and edge retention when cutting hard or abrasive materials. Overall length is 2.992 inches with a flute length of 1.732 inches. Machinists, toolmakers, and fabricators working on production drilling applications will find this bit suited to sustained, high-throughput use.

The C16805 is rated for use across a broad range of materials including aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. The taper length format provides added reach compared to jobber-length bits, making it appropriate for deeper hole applications or workpiece configurations where a standard-length bit falls short. The straight shank accepts standard drill chucks without adapters, and the right-hand cut suits conventional drilling setups on lathes, drill presses, CNC machining centers, and hand-held power tools.

Key Features

• 1.5 mm diameter with tight tolerance of +0.0000 to -0.0005 inches for accurate hole sizing
• 135-degree split point reduces thrust force and minimizes bit walking on entry
• Parabolic flute design promotes efficient chip evacuation in deep-hole drilling
• M42 cobalt grade material provides superior heat and wear resistance over standard HSS
• Web-thinned, tapered web configuration reduces cutting resistance and extends tool life
• Meets ASME B94.11M and DIN 340 standards; referenced to DIN 338 specification

Compatibility

Compatible with standard straight-shank drill chucks. Rated for drilling aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. Shank diameter is 1.5 mm (0.0591 inches), compatible with collets and chucks sized to accept that diameter.

Installation Notes

Secure the shank fully in a properly sized drill chuck or collet before operation. Ensure the workpiece is clamped or fixtured to prevent rotation or movement during drilling. Use cutting fluid or coolant appropriate for the workpiece material to extend tool life, particularly when drilling stainless steel or nickel alloys. Inspect the cutting edges for wear or chipping before each use; a dull or damaged bit should be replaced or reground before returning to service.
