Cleveland C04502 Drill Bit Letter B 0.238 in Hss 118 Pt

Product Description

The CLEVELAND C04502 is a screw machine length drill bit sized to Letter B (0.2380 inches diameter) and built from high-speed steel with a bright, uncoated finish. The 118-degree standard point angle delivers consistent entry geometry on a wide range of workpiece materials. At 2.5 inches overall length, the short-series body fits tight clearances and stub drilling applications where a jobber-length bit would not seat properly. Two spiral flutes clear chips efficiently, and the straight-cylindrical shank measures 0.2380 inches in diameter for direct chuck mounting. Web thinning reduces thrust requirements at the point. This bit is used by machinists, tool-and-die technicians, and maintenance trades across production and repair environments.

The C04502 is suited for drilling alloy steels and aluminum in both manual and CNC drilling applications. Its short overall length and parallel web configuration make it appropriate for screw machine work, turret lathe setups, and close-tolerance production drilling. The general-purpose grade and ASME B94.11M compliance position it as a reliable stock item for shops requiring consistent results across mixed-material runs. Right-hand cutting direction is standard for conventional drill press and machine spindle rotation.

Key Features

• Letter B diameter: 0.2380 inches with a tight tolerance of +0.0000 to -0.0007 inches
• 118-degree standard point angle for general-purpose entry geometry
• High-speed steel construction with bright, uncoated finish
• Short-series 2.5-inch overall length fits screw machines and turret setups
• Two spiral flutes with web thinning to reduce cutting thrust
• Meets ASME B94.11M dimensional standard

Compatibility

Designed as a general-purpose screw machine length drill bit for use in standard drill chucks and collets accepting a 0.2380-inch straight-cylindrical shank, with primary workpiece materials including alloy steel and aluminum.

Installation Notes

Install in a properly rated drill press, CNC drilling machine, or screw machine spindle using a chuck or collet matched to the 0.2380-inch shank diameter. Ensure the workpiece is securely fixtured before engaging the spindle. Use appropriate cutting fluid or lubrication when drilling alloy steels to maintain edge life and control chip loading. Inspect the cutting point for wear or chipping between uses, as a damaged point will affect hole diameter tolerance and surface finish.
