M.a. Ford. 64100003 Countersink Set 4 Pc 90 Degree Hss

Product Description

The M.A. FORD. 64100003 is a 4-piece high speed steel countersink set covering head diameters from 1/4 inch to 1 inch. Each tool features a single flute, a 90-degree included angle, and a straight shank with right-hand cutting direction. The bright polished finish reduces friction and aids chip evacuation. These countersinks are sized for production and maintenance shops where consistent 90-degree seat geometry is required across a range of fastener sizes. Machinists, toolroom technicians, and maintenance mechanics are the primary users of this set.

This set is suited for countersinking operations on a broad range of materials including alloy steel, mild steel, stainless steel, cast iron, high tensile steel, high nickel steel, Monel, aluminum, aluminum alloy, brass, magnesium, magnesium alloy, and plastics. The 45-degree centerline angle and straight shank make these tools compatible with standard drill press chucks and hand-held electric drills. The set ships in a plastic storage case that keeps all four countersinks organized and protected between uses.

Installation Notes

Secure the straight shank firmly in the drill chuck before operation and verify runout before engaging the workpiece. Power down and de-energize the machine before changing or adjusting countersinks. Use appropriate cutting fluid or lubricant when working with steel or stainless steel to extend tool life. Always wear appropriate eye protection and follow shop safety procedures when operating rotary cutting tools.
