Cleveland C71093 Jobber Length Drill Bit Letter W Hss

Product Description

The CLEVELAND C71093 is a jobber-length drill bit sized to Letter W (0.3860 inches), ground from high speed steel and finished with a black oxide coating for added lubricity and corrosion resistance. The 118-degree standard point angle suits a wide range of materials in general-purpose drilling applications. A web-thinned, tapered web design reduces thrust at the point and improves chip clearance. At 5.125 inches overall length with a 3.75-inch spiral flute, this bit provides the reach and chip evacuation needed for production and maintenance drilling in metal, wood, and plastics. It is installed and used by machinists, maintenance technicians, and fabricators.

The C71093 is suited for general-purpose drilling in job shop, maintenance, and light manufacturing environments. The straight-cylindrical shank accepts standard 3-jaw chucks on drill presses, hand drills, and CNC machines. The regular spiral, two-flute design handles a broad range of workpiece materials at conventional feed and speed parameters. The Series 2001G designation places this bit within a standard jobber-length line conforming to ASME B94.11M and DIN 338.

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw drill chuck accepting a 0.3860-inch straight-cylindrical shank, including drill presses, portable hand drills, and CNC drilling machines.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck. Ensure the shank is fully seated and the chuck is firmly tightened before operation. Select appropriate feed rate and spindle speed for the workpiece material to avoid overheating the cutting edge. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling steel or other ferrous materials to extend tool life.
