M.a. Ford 20605500 Screw Machine Drill Bit Carbide

Product Description

The M.A. FORD 20605500 is a solid carbide screw machine length drill bit designed for precision drilling in demanding shop and production environments. With a 0.055 inch diameter (wire size #54) and a 118-degree faceted drill point, it delivers accurate, clean entry into tight-tolerance workpieces. The bright/uncoated finish suits direct use or post-treatment applications. At 1.5 inches overall length with a 0.375 inch flute length, this short-length geometry provides rigidity and reduces deflection. Right-hand spiral flutes efficiently evacuate chips during drilling operations. Licensed machinists and tool-and-die professionals are the primary users of this bit.

This drill bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and steel across a range of production and repair applications. Its screw machine length profile makes it a practical choice for drill press and CNC work where stub-length rigidity is needed. The straight-cylindrical shank fits standard drill chucks without modification. Web-thinned geometry reduces thrust force at the point, easing penetration in harder alloys and tightly toleranced setups.

Key Features

• Solid carbide construction for wear resistance in ferrous and non-ferrous materials
• 118-degree faceted point for accurate self-starting entry
• Web-thinned, parallel web configuration reduces axial thrust
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Bright/uncoated finish compatible with post-coating if required
• Diameter tolerance held to +0.0000 to -0.0005 inches for precision fitment

Compatibility

Designed as a screw machine length drill bit in the M.A. FORD Series 206 for use in materials including cast iron, non-ferrous metal, stainless steel, and steel with a diameter range covering 0.0000 to 0.1000 inches.

Installation Notes

Installation of small-diameter carbide drill bits should be performed by qualified machinists or tooling technicians. Secure the straight-cylindrical shank firmly in a compatible drill chuck rated for the intended spindle speed before operation. Carbide tooling is brittle and susceptible to chipping from side loading or improper seating; inspect the shank and chuck taper for debris before clamping. Always power down and de-energize the machine before changing tooling.
