M.a. Ford 22651180 Carbide Screw Machine Drill Bit 0.5118in

Product Description

The M.A. FORD 22651180 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. With a 0.5118-inch (13.00 mm) diameter and a standard 118-degree faceted point angle, this bit delivers clean entry and consistent hole geometry. The bright/uncoated finish suits applications where coating buildup is a concern or where cutting fluid does the heavy lifting. At 4.0157 inches overall length and a flute-to-diameter ratio of 3xD, this short-length design provides rigidity and reduced deflection in CNC machining centers and manual drill presses alike. Web thinning reduces thrust load at entry, making it a practical choice for production drilling environments.

This bit is rated for use in cast iron, non-ferrous metals, stainless steel, and steel. The screw machine (stub) length format makes it well suited for short-reach applications where a standard jobber-length bit would introduce excess runout or chatter. Typical install scenarios include production machining shops, maintenance and repair operations, and toolroom setups. The straight-cylindrical shank accepts standard drill chucks without adapters, and the 2.0079-inch shank length provides solid grip in both manual and automated toolholding systems.

Key Features

• Solid carbide construction for heat resistance and long tool life in ferrous and non-ferrous materials
• 118-degree faceted point for fast, accurate hole entry with minimal walking
• Web-thinned parallel web reduces drilling thrust and improves chip evacuation
• Bright/uncoated finish compatible with most cutting fluids and coolant strategies
• Short screw machine length (3xD flute ratio) maximizes rigidity and minimizes deflection
• Manufactured to DIN 6539 specification for consistent dimensional accuracy

Compatibility

Designed for drilling cast iron, non-ferrous metal, stainless steel, and steel. Straight-cylindrical shank fits standard drill chucks accepting a 0.5118-inch (13.00 mm) shank diameter. Conforms to DIN 6539 specification.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom professionals familiar with speeds and feeds for solid carbide tooling. Always secure the workpiece and verify chuck runout before beginning a drilling operation. Solid carbide tooling is brittle compared to high-speed steel — avoid lateral loading or interrupted cuts unless the setup is confirmed rigid. Follow machine tool manufacturer guidelines for spindle speed, feed rate, and coolant application appropriate to the workpiece material.
