Cleveland C04650 Screw Machine Drill Bit 27/32 in Hss

Product Description

The CLEVELAND C04650 is a screw machine length (stub) drill bit designed for general-purpose drilling in metal fabrication, machining, and light industrial applications. Ground from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree standard point angle and a web-thinned tip that reduces thrust and helps the bit start cleanly without walking. The straight-cylindrical shank measures 0.8438 inches in diameter, matching the bit diameter, for secure chuck engagement. With an overall length of 5.375 inches and a flute length of 3.5 inches, the shorter stub profile offers added rigidity over jobber-length bits, making it well suited for use in tight clearance environments or drill presses.

This drill bit is intended for right-hand cutting in alloy steel, aluminum, and similar workpiece materials. The short screw machine length format is a standard choice in CNC machining centers, turret lathes, and manual drill press work where deflection control and concentricity are priorities. It conforms to ASME B94.11M and ANSI specification designations, making it a drop-in fit wherever those standards apply. Machinists, tool-and-die workers, and maintenance technicians working in production or job-shop environments will find this bit appropriate for their general drilling needs.

Key Features

• High-speed steel construction for general-purpose metal drilling
• 118-degree standard point angle with web-thinned tip for reduced entry thrust
• Screw machine (stub) length adds rigidity and minimizes deflection
• Straight-cylindrical shank at 0.8438 inches fits standard drill chucks
• Bright/uncoated finish suitable for use with cutting fluids
• Right-hand spiral flutes, 2-flute configuration for efficient chip evacuation
• Meets ASME B94.11M and ANSI standards

Compatibility

Designed as a general-purpose replacement or stock drill bit for use in standard drill chucks, CNC turrets, and manual drill presses accepting straight-cylindrical shanks in the 0.8438-inch diameter range. Primary workpiece materials listed by the manufacturer include alloy steel and aluminum.

Installation Notes

This bit should be installed by a qualified machinist or maintenance technician familiar with cutting tool setup. Ensure the drill chuck or collet is fully engaged on the straight shank before operation, and verify the chuck key is removed before powering the machine. When drilling steel, use an appropriate cutting fluid to extend tool life and improve finish quality. Do not exceed the spindle speed recommended for the workpiece material and bit diameter.
