Cleveland C04526 Drill Bit Letter K Hss 118 Degree

Product Description

The CLEVELAND C04526 is a screw machine length drill bit designed for high-frequency drilling in production and shop environments. Manufactured from high-speed steel with a bright uncoated finish, it accepts Letter K sizing at 0.2810 inches diameter. The 118-degree standard point angle provides a reliable entry geometry for a wide range of workpiece materials. At 2-11/16 inches overall length with a 1-1/2 inch flute length, the short body reduces deflection and improves rigidity when drilling in drill presses, lathes, or CNC setups. Web-thinned construction lowers thrust requirements and helps the bit start cleanly without a pilot hole in most applications. This bit is installed by machinists, tool-and-die technicians, and maintenance mechanics.

This drill bit is suited for general-purpose drilling in alloy steels and aluminum in both production and maintenance-repair operations. The straight cylindrical shank fits standard drill chucks without adapters. Its short overall length makes it well matched to screw machine spindles, turret lathes, and bench-top drill presses where a jobber-length bit would have excessive overhang. Right-hand cut and two-flute spiral geometry are standard for most metal-drilling workflows.

Key Features

• Letter K size: 0.2810 inches diameter with a tolerance of +0.0000 to -0.0010 inches
• 118-degree standard point angle for general-purpose entry geometry
• High-speed steel construction rated for alloy steel and aluminum workpieces
• Web-thinned, parallel web design reduces thrust and improves chip clearance
• Short screw machine length body minimizes deflection in production drilling setups
• Conforms to ASME B94.11M standard

Compatibility

Designed as an OEM-style replacement or direct-use bit for standard drill chucks accepting a 0.2810-inch straight cylindrical shank in screw machine, lathe turret, and bench drill press applications.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a standard keyed or keyless drill chuck. Power down and lock out the machine before inserting or removing the bit. Secure the shank fully in the chuck to the depth recommended by the machine manufacturer to prevent pullout under load. General shop safety and applicable OSHA machine-guarding standards apply when operating drilling equipment.
