Value Collection SC208210S Countersink Set 10 Pc Hss

Product Description

The VALUE COLLECTION SC208210S is a 10-piece high-speed steel countersink set designed for creating clean, accurate countersunk holes across a range of fastener sizes. The set covers head diameters from 1/4 inch to 1-1/2 inches, with a consistent 82-degree included angle suited to standard flat-head fastener seating. Each countersink features a 6-flute design with right-hand cutting direction and a straight shank. The bright, uncoated finish indicates the tools are ready-to-use high-speed steel without additional coating. Machinists, fabricators, and tool-and-die professionals will find this set appropriate for production and maintenance work on ferrous and non-ferrous materials.

This countersink set is intended for general countersinking applications in metal fabrication, woodworking shops, and maintenance environments. The 10-piece range allows a technician to match the correct tool to the fastener being seated without switching to a separate set. Each tool cuts in the right-hand direction and accepts a straight shank in compatible drill presses, CNC machines, or hand-held power drills. The included 82-degree angle is the standard for most flat-head machine screws used in North American manufacturing and assembly work. Tools store in the included wooden block for organized bench or toolbox storage.

Compatibility

Designed as a general-purpose countersink set compatible with standard drill presses, CNC machines, and power drills that accept straight-shank tooling; the 82-degree angle suits the vast majority of flat-head machine screws used in metalworking and fabrication applications.

Installation Notes

Countersinks should be installed by a qualified machinist or experienced fabricator familiar with proper spindle speeds and feed rates for the material being worked. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped to prevent movement. Start at a lower spindle speed and increase as needed; excessive speed or feed can cause chatter or premature tool wear. Inspect flute edges before each use and replace any tool showing signs of chipping or dullness.
