M.a. Ford 20408600 Carbide Drill Bit No. 44 0.0860 in

Product Description

The M.A. FORD 20408600 is a solid carbide jobber length drill bit in wire gauge size No. 44, with a decimal diameter of 0.0860 inches. It features a 118-degree faceted drill point and a regular spiral flute configuration with web thinning for improved chip evacuation and reduced thrust at entry. The overall length is 2 inches, with a 1-inch flute length. The bright, uncoated finish suits general-purpose drilling applications. This bit is designed for use by machinists, tool-and-die technicians, and other precision metalworking professionals who require consistent performance in tight-tolerance bore work.

The 20408600 is suited for drilling cast iron, non-ferrous metals, stainless steel, and carbon or alloy steel in production and job-shop environments. The 5xD flute-to-diameter ratio and right-hand spiral flute make it a practical choice for through-hole and blind-hole applications on CNC machining centers, drill presses, and manual mills where a straight-cylindrical shank is required. It is a general-purpose grade bit appropriate for moderate-speed, non-coolant-through setups.

Compatibility

Designed as a general-purpose replacement or production bit for any machine tool accepting a straight-cylindrical shank in the 0.0860-inch diameter range, including CNC machining centers and drill presses. Primary workpiece materials include cast iron, non-ferrous metal, stainless steel, and steel (material codes K, M, N, P).

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup and safe machine operation. Always power down and de-energize the machine spindle before changing tooling. Verify chuck jaw condition and shank seating before running the spindle. Follow the machine manufacturer's recommended speeds and feeds for solid carbide tooling and the specific workpiece material being drilled.
