Cleveland C04500 Screw Machine Drill Bit 15/64 in Hss

Product Description

The CLEVELAND C04500 is a screw machine length drill bit designed for general-purpose drilling in metal fabrication, machining, and mechanical assembly applications. Built from high-speed steel (HSS) with a bright/uncoated finish, it features a 118-degree standard point angle and a web-thinned tip geometry that reduces thrust and improves chip evacuation at entry. The 15/64 inch (0.2344 inch) diameter is held to a tight tolerance of +0.0000 to -0.0007 inches, ensuring consistent hole sizing. With an overall length of 2-7/16 inches, this short-length bit offers increased rigidity compared to jobber-length equivalents, making it well suited for close-tolerance work on manual and CNC machine tools.

The C04500 is intended for use in drill presses, screw machines, turret lathes, and CNC machining centers where stub-length rigidity is required. Primary workpiece materials include alloy steel and aluminum. The straight-cylindrical shank measures 0.2344 inches in diameter and 1-1/8 inches in length, allowing direct chuck mounting on standard equipment. This bit is a practical choice for production shops, maintenance machinists, and tool room applications where dimensional accuracy and consistent performance across repeated operations are priorities.

Key Features

• High-speed steel construction provides adequate hardness and wear resistance for general-purpose metal drilling
• 118-degree standard point angle suits a broad range of metalworking applications
• Web-thinned tip with parallel web configuration reduces entry thrust and improves chip flow
• Screw machine (short) length increases rigidity and reduces deflection compared to jobber-length bits
• Bright/uncoated finish allows direct inspection of cutting edge condition during use
• Right-hand cut with two spiral flutes; conforms to ASME B94.11M standards

Compatibility

Designed as a general-purpose replacement or stock bit for screw machines, drill presses, turret lathes, and CNC machining centers accepting a straight-cylindrical shank. Suitable for workpieces in alloy steel and aluminum per Series 2120 application parameters.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or maintenance technician familiar with machine tool operation. Secure the straight-cylindrical shank firmly in a calibrated chuck before operation and verify runout before production cuts. Always power down and lock out the spindle before inserting or removing the bit. Do not exceed the recommended speed and feed parameters for the workpiece material and bit diameter.
