M.a. Ford. 92000012 Countersink Set 5 Pc Hss

Product Description

The M.A. FORD. 92000012 is a 5-piece high speed steel countersink set covering head diameters from 0.25 inches to 0.75 inches. Each countersink features 3 flutes and an 82-degree included angle, the standard angle for most fastener applications in metal, wood, and composite materials. Shank diameters range from 0.25 inches to 0.75 inches, with overall lengths spanning 1.25 inches to 4.25 inches across the set. The bright polished finish reduces friction and aids chip evacuation. This set suits machinists, fabricators, and general tradespeople who need a range of countersink sizes in a single organized case.

This countersink set is suited for countersinking operations in production, maintenance, and repair environments. The 82-degree angle matches the geometry of most flat-head machine screws and sheet metal fasteners used in light fabrication and assembly work. Right-hand cutting direction is compatible with standard drill press and hand-drill setups. The set ships in a plastic storage case that keeps all five pieces organized and protected between uses.

Key Features

Compatibility

Designed as a general-purpose countersink set compatible with standard drill presses and hand drills accepting straight-shank tooling in the corresponding shank diameter range.

Installation Notes

Secure the workpiece firmly before beginning countersinking operations to prevent movement and ensure a clean seat angle. Set spindle speed appropriate to the material being cut — harder metals require lower RPM than wood or plastics. Select the countersink whose shank diameter matches the chuck or collet capacity of the machine being used. Inspect cutting edges before each use and replace any countersink showing chipping or dulling to avoid poor fastener seating.
