Value Collection SC10825S Countersink Set 5 Pc Hss 82 Deg

Product Description

The VALUE COLLECTION SC10825S is a 5-piece countersink set designed for creating clean, accurately angled seat recesses in metal, wood, and composite materials. Each countersink features a single flute geometry and an 82-degree included angle, which is the standard angle for flat-head fastener seating in most metalworking and woodworking applications. Head diameters range from 1/4 inch to 1 inch across the five pieces, giving a technician or machinist coverage for a wide range of fastener sizes in a single set. All cutters are machined from high-speed steel (HSS) with a bright, uncoated finish. The straight shanks range from 1/4 inch to 1/2 inch in diameter. The set ships stored in a wood block for organized bench or toolbox storage.

This countersink set is suited for use in fabrication shops, maintenance facilities, plumbing rough-in work, electrical panel and enclosure work, and HVAC equipment assembly where flat-head fasteners must seat flush. Single-flute countersinks at this angle are commonly used on steel, aluminum, and similar materials where a clean entry cut and accurate angle are needed. The wood storage block keeps all five pieces indexed and accessible during active use.

Installation Notes

Countersinks should be installed by machinists, maintenance technicians, or trade professionals familiar with rotating cutting tools and proper feed and speed selection for the workpiece material. Secure the shank firmly in the chuck or collet before use, and ensure the workpiece is clamped securely to prevent movement. Do not force the cutter; light, consistent feed pressure produces the cleanest seat. Inspect the cutting edge for wear or chipping before each use and replace any damaged cutter immediately.
