M.a. Ford 20709380 Screw Machine Drill Bit 3/32 in

Product Description

The M.A. FORD 20709380 is a solid carbide screw machine length drill bit ground to a 3/32-inch (0.0938 inches) diameter with a straight-cylindrical shank of equal diameter. Built for precision drilling in non-ferrous metals, this bit features a brad point, a regular spiral flute geometry, and a bright uncoated finish that maintains tight dimensional tolerances straight out of the box. At 1-3/4 inches overall length with a 1/2-inch flute length, it is sized for compact drilling stations and screw machine operations where stub-length control matters. A web-thinned, parallel web configuration reduces thrust and improves chip evacuation in short-bore applications. Licensed machinists, tool-and-die technicians, and CNC setup personnel are the primary installers.

This drill bit is designed for screw machine and short-hole drilling operations in non-ferrous metals such as aluminum, brass, copper, and similar soft alloys. The 3xD flute-to-diameter ratio and the 1-1/4-inch shank length suit gang-drilling fixtures, turret lathes, and benchtop drill presses where rigidity and repeatability at small diameters are critical. The right-hand cut and spiral flute design pull chips upward and out of the bore, reducing the risk of re-cutting in shallow blind holes. No coolant-through capability is required for typical non-ferrous applications at this diameter.

Key Features

• Solid carbide construction delivers superior hardness and wear resistance compared to high-speed steel at small diameters
• Brad point tip geometry improves entry accuracy and reduces walking on flat or curved non-ferrous workpieces
• Web-thinned parallel web reduces axial thrust and improves chip clearance in short-depth bores
• Bright uncoated finish maintains as-ground sharpness with no coating buildup at tight tolerances
• Diameter tolerance held to +0.0000 to -0.0005 inches for consistent fit in precision hole applications
• Straight-cylindrical shank seats directly in standard collets and drill chucks without adapter reduction

Compatibility

Designed as a screw machine length replacement or production drill bit for operations requiring a 3/32-inch (0.0938 inches) solid carbide bit in non-ferrous metal applications; compatible with standard straight-shank collets and three-jaw drill chucks accepting 0.0938-inch shanks.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with small-diameter carbide tooling. Always seat the shank fully and evenly in the collet or chuck before tightening to prevent runout. Carbide is brittle at this diameter — avoid side loading, interrupted cuts, or excessive feed rates that can cause fracture. Power down and lock out the spindle before changing or inspecting tooling.
