Cleveland C04499 Drill Bit Letter a Hss 118 Degree

Product Description

The CLEVELAND C04499 is a screw machine length (stub-length) drill bit sized to Letter A, equivalent to 0.2340 inches in diameter. Built from high-speed steel with a bright, uncoated finish, it is designed for general-purpose drilling in alloy steel, aluminum, and similar workpiece materials. The 118-degree standard point angle and web-thinned geometry reduce entry force and help the bit self-center on contact. Two spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. The shorter overall length of 2-7/16 inches provides added rigidity compared to jobber-length bits, making it a reliable choice for production drilling setups, drill presses, and CNC operations where deflection must be minimized.

This bit fits standard drilling applications in metal fabrication shops, maintenance environments, and light manufacturing. The straight cylindrical shank at 0.2340 inches in diameter seats in standard three-jaw drill chucks without adapters. Its short flute length of 1-5/16 inches and compact overall length make it well-suited for tight-clearance work or fixtures where a full-length jobber bit would interfere. General-purpose grade makes it appropriate for intermittent production runs rather than high-volume continuous feed operations. Conforms to ASME B94.11M standards.

Key Features

• Letter A size — 0.2340 inches decimal equivalent with a tight tolerance of +0.0000 to -0.0007 inches
• 118-degree standard point angle with web-thinned geometry for reduced thrust and improved self-centering
• High-speed steel construction — suitable for alloy steel, aluminum, and general-purpose metal drilling
• Screw machine (short) length at 2-7/16 inches OAL for increased rigidity and reduced deflection
• Straight cylindrical shank fits standard drill chucks without sleeves or adapters
• Conforms to ASME B94.11M and ANSI specification standards

Compatibility

Designed as a general-purpose OEM-style screw machine length drill bit compatible with any standard drill chuck or collet system accepting a 0.2340-inch straight cylindrical shank. Suitable for use in drill presses, CNC machining centers, and hand-held power drills used in metal fabrication and maintenance applications.

Installation Notes

Installation of this bit should be performed by a qualified machinist or trade professional familiar with rotating cutting tool safety. Secure the shank fully in the chuck and verify concentricity before engaging the workpiece. Always wear appropriate eye protection and follow applicable shop safety standards when operating drilling equipment. Inspect the cutting edges for wear or chipping before each use and replace if the bit shows signs of dulling to maintain dimensional accuracy and safe operation.
