M.a. Ford 64100073 Countersink Set 7 Pc Hss 90 Degree

Product Description

The M.A. FORD 64100073 is a 7-piece single-flute countersink set designed for creating clean, angled seating recesses for flat-head fasteners. Built from high speed steel (HSS) with a bright polished finish, the set covers head diameters from 3/16 inches to 1 inch, all at a 90-degree included angle and 45-degree centerline angle. Cutting direction is right hand. The set stores in a plastic case for organized access on the job. It is suited for machinists, tool-and-die workers, and maintenance technicians who require consistent countersink geometry across a range of hole sizes.

This set is intended for use on a broad range of materials in both production and maintenance environments. Compatible materials include alloy steel, mild steel, high tensile steel, high nickel steel, stainless steel, cast iron, Monel, brass, aluminum, aluminum alloy, magnesium, magnesium alloy, and plastics. The 7-piece range makes the set practical for shops that handle varied fastener sizes without switching between individual countersinks. It is appropriate for drilling press, lathe, or hand-held power tool use where a straight shank tool is accepted.

Key Features

• 7-piece set covering 3/16 inches to 1 inch head diameter range
• Single-flute geometry for smooth finish cuts on a wide range of materials
• 90-degree included angle suits standard flat-head fastener seating
• High speed steel construction for durability across ferrous and non-ferrous materials
• Bright polished finish reduces friction and aids chip evacuation
• Straight shank fits standard drill chucks without adapters
• Plastic storage case keeps all 7 countersinks organized and protected

Compatibility

Designed as an OEM-style replacement or general-purpose countersink set for use with any drill press, CNC machine, or hand-held power tool equipped with a straight-shank chuck. Suitable for countersinking applications in alloy steel, aluminum, brass, cast iron, stainless steel, magnesium, Monel, high nickel steel, high tensile steel, mild steel, and plastics.

Installation Notes

This tool is installed and used by machinists, fabricators, and maintenance technicians. Secure the workpiece firmly before starting a cut, and set spindle speed appropriate for the material being machined — harder materials require lower RPM. Ensure the drill chuck is tightened properly around the straight shank before operation. Inspect the cutting edges before each use and remove the tool from service if chipping or wear is evident.
