M.a. Ford. 20410940 Solid Carbide Jobber Drill Bit 7/64

Product Description

The M.A. FORD. 20410940 is a solid carbide jobber length drill bit designed for precision drilling in demanding materials. It measures 7/64 inches (0.1094 inches decimal) in diameter with a 118-degree faceted drill point and a 2-1/4 inch overall length. The bright, uncoated carbide construction delivers rigidity and wear resistance in applications where high-speed steel would deflect or dull prematurely. A right-hand spiral flute with web-thinned, tapered web geometry reduces thrust at entry and promotes chip evacuation. This bit suits machinists, fabricators, and maintenance technicians working on ferrous and non-ferrous stock.

This drill bit is rated for general-purpose use across a range of workpiece materials including cast iron, non-ferrous metals, stainless steel, and carbon steel. Its 5xD flute-to-diameter ratio and regular spiral type make it well-suited for through-holes and spot-drilling in production or job-site environments. The straight-cylindrical shank fits standard drill chucks without adapters, making it compatible with benchtop drill presses, CNC machining centers, and hand-held drill drivers where carbide tooling is appropriate.

Key Features

• Solid carbide construction for superior hardness and heat resistance compared to HSS
• 118-degree faceted point with web-thinned, tapered web for reduced entry thrust
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Bright uncoated finish suitable for dry cutting or light lubrication applications
• Straight-cylindrical shank fits standard drill chucks without special toolholders
• ISO 9001:2015 certified manufacturing under Series 204

Compatibility

Rated for primary workpiece materials including cast iron (material code K), stainless steel (M), non-ferrous metals (N), and carbon and alloy steels (P). Fits any standard chuck accepting a 7/64 inch straight shank. Suitable for manual and CNC drilling operations within the 0.1000 to 0.1500 inch drill diameter range.

Installation Notes

Solid carbide tooling should be installed by qualified machinists or tooling technicians familiar with carbide handling requirements. Secure the shank fully in the chuck and verify runout before drilling, as carbide is brittle and sensitive to lateral loading. Power down the machine and lock out energy sources before changing tooling per applicable lockout/tagout procedures. Avoid using carbide bits in applications with significant vibration or interrupted cuts unless the bit is specifically rated for that condition.
