M.a. Ford. 20610940 Carbide Screw Machine Drill Bit 7/64

Product Description

The M.A. FORD. 20610940 is a solid carbide screw machine length drill bit designed for high-precision short-hole drilling in demanding production and job-shop environments. At 0.1094 inches (7/64 inch) in diameter with a 118-degree faceted point angle, it delivers clean entry geometry suited to a range of metalworking applications. The bright/uncoated finish maintains dimensional accuracy right out of the box. With a 2-flute spiral configuration and web-thinned parallel web, this bit reduces thrust and improves chip evacuation. Machinists, tool-and-die technicians, and CNC operators working with ferrous and non-ferrous materials rely on this bit for consistent, repeatable hole quality in short-run and high-volume setups.

This drill bit is built for cutting cast iron, non-ferrous metals, stainless steel, and steel. The screw machine (stub) length format — 2 inches overall — provides added rigidity compared to jobber-length bits, making it especially effective on CNC machining centers, drill presses, and manual machines where minimizing deflection matters. The straight-cylindrical shank seats securely in standard drill chucks and collets. The 3xD flute-to-diameter ratio and 0.625-inch flute length keep the tool compact while handling typical short-hole depths.

Key Features

• Solid carbide construction for hardness and wear resistance in ferrous and non-ferrous metals
• 118-degree faceted drill point for accurate self-centering on entry
• Web-thinned parallel web reduces axial thrust and improves chip flow
• Bright/uncoated finish — no coating buildup, preserves close diameter tolerance
• Diameter tolerance held to +0.0000 to -0.0005 inches for tight-fit hole applications
• Right-hand spiral flute, 2-flute configuration for efficient chip evacuation

Compatibility

Designed for use in standard drill chucks and collets accepting a 0.1094-inch straight-cylindrical shank. Suitable for drilling cast iron, non-ferrous metals, stainless steel, and steel as identified in M.A. FORD. Series 206 product specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with proper speeds, feeds, and clamping practices for carbide tooling. Power down and de-energize the machine spindle completely before changing tooling. Secure the shank fully in the chuck or collet to the manufacturer-recommended engagement depth to prevent pullout and bit breakage. Carbide tooling is brittle — avoid side loading, interrupted cuts beyond the tool rating, or dropping the bit on hard surfaces.
