Cleveland C04596 Screw Machine Drill Bit 15/32 in Hss

Product Description

The CLEVELAND C04596 is a screw machine length drill bit designed for high-speed steel cutting in general-purpose drilling applications. With a 15/32 inch (0.4688 inch decimal) diameter and a 118-degree standard point angle, this bit delivers clean entry and consistent hole geometry across a range of workpiece materials. The stub-length body reduces deflection compared to jobber-length bits, making it a practical choice for production drilling in tight setups. It features a right-hand spiral flute configuration and a straight-cylindrical shank for use in standard drill chucks and tool holders. Web-thinned geometry reduces thrust requirements at the start of the cut.

This drill bit is suited for metalworking applications in shop, maintenance, and light manufacturing environments. Primary workpiece materials include alloy steel and aluminum. The short overall length of 3-5/8 inches and 2-1/8 inch flute length make it well-matched to drill press, mill, or hand-drill setups where reduced overhang is preferred. It is commonly used by machinists, millwrights, pipefitters, and maintenance technicians who require a reliable general-purpose bit for repetitive hole drilling in metal components.

Key Features

• 15/32 inch diameter with a tight tolerance of +0.0000 to -0.0010 inches for consistent hole sizing
• 118-degree standard point angle with web-thinned geometry for reduced entry thrust
• High-speed steel construction rated for general-purpose cutting in alloy steel and aluminum
• Screw machine (stub) length at 3-5/8 inches OAL minimizes deflection in close-clearance setups
• Straight-cylindrical shank at 0.4688 inches diameter fits standard chucks without adapters
• Bright/uncoated finish; no coolant-through feature; suitable for dry or flooded cutting

Compatibility

Designed as a general-purpose screw machine length drill bit conforming to ASME B94.11M and ANSI specifications, compatible with standard drill chucks and tool holders accepting a straight-cylindrical shank in the 15/32 inch diameter range.

Installation Notes

This bit is installed and serviced by machinists, maintenance technicians, and trades professionals using standard drill press, lathe, or hand-drill equipment. Before changing bits, ensure the machine is fully powered down and the chuck is secured before tightening. Use appropriate cutting fluid for alloy steel workpieces to extend tool life. Inspect the cutting edges and web condition before each use; a worn or chipped point will increase thrust and reduce hole quality.
