M.a. Ford. 20610400 Solid Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD. 20610400 is a solid carbide screw machine length drill bit with a 0.104 inch (Wire Size 37) diameter and a bright/uncoated finish. It features a 118-degree faceted point angle, a 2-flute regular spiral flute design, and a straight-cylindrical shank. The overall length is 2 inches, making it a compact, short-length tool suited for high-precision drilling in tight setups. Web-thinned geometry reduces thrust and improves chip evacuation. This bit is intended for machinists, tool and die professionals, and production shop technicians working on close-tolerance drilling operations.

This drill bit is designed for use in screw machine work and general precision drilling applications. It is well suited for drilling cast iron, non-ferrous metals, stainless steel, and steel in both manual and CNC drilling setups. The short flute length of 0.625 inches and a 3xD flute-to-diameter ratio make it appropriate for shallow, accurate holes where rigidity and runout control are critical. It fits standard drill chucks and collet systems accepting a 0.104 inch straight shank.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard and abrasive materials
• 118-degree faceted point angle with web-thinned, parallel web configuration for reduced entry thrust
• Bright/uncoated finish compatible with a wide range of workpiece materials and cutting fluids
• Right-hand cut with regular spiral flutes for consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Diameter tolerance of +0.0000 to -0.0005 inches for tight-tolerance hole requirements

Compatibility

Designed for use with standard drill chucks and collet systems accepting a 0.104 inch straight-cylindrical shank. Suitable for drilling cast iron, non-ferrous metal, stainless steel, and steel workpieces as specified by the manufacturer for M.A. FORD. Series 206.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool operators familiar with carbide tooling. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Carbide is brittle — avoid side loading or interrupted cuts that can cause chipping or breakage. Follow machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material and hole depth.
