Cleveland C14805 Cobalt Screw Machine Drill Bit 0.1772 in

Product Description

The CLEVELAND C14805 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding industrial and metalworking applications. The bit measures 0.1772 inches in diameter with a 2.283-inch overall length and features a 135-degree split point for fast penetration and reduced walking on entry. Manufactured from M42 cobalt high-speed steel, it handles higher heat and wear than standard HSS bits, making it well suited for tough or abrasive workpiece materials. The two-flute, right-hand spiral design evacuates chips efficiently during the cut. This bit is sold individually and is intended for installation in standard drill chucks by machining or fabrication professionals.

This bit is built for use in screw machine operations, CNC drilling setups, and manual drill press work where short, rigid tooling is required. Primary workpiece materials include alloy steels and aluminum. The screw machine length body is shorter than jobber-length bits, reducing deflection in high-feed or high-speed applications. The straight-cylindrical shank at 0.1772 inches diameter fits standard three-jaw chucks without modification. The web-thinned, parallel-web construction reduces thrust load and extends usable tool life in production environments.

Key Features

• M42 cobalt construction for elevated heat resistance and extended tool life in hard materials
• 135-degree split point reduces entry thrust and minimizes bit walking on smooth surfaces
• Screw machine length body at 2.283 inches OAL provides added rigidity and reduced deflection
• Web-thinned parallel web lowers cutting resistance and improves chip flow
• Right-hand, two-flute spiral design for efficient chip evacuation in metals
• Diameter tolerance held to +0.0000 to -0.0007 inches per ASME B94.11M and DIN 1897 standards

Compatibility

Designed as an OEM-style replacement or production-grade addition for use in standard straight-shank drill chucks; rated for primary workpiece materials including alloy steel and aluminum as specified by the manufacturer.

Installation Notes

Installation is performed by machinists or fabrication technicians using a standard keyed or keyless drill chuck. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight shank fully within the chuck jaws to prevent slippage under feed load. Follow applicable shop safety and machine guarding practices when operating at elevated speeds in metal drilling applications.
