Product Description

The VALUE COLLECTION SC50905S is a 5-piece high-speed steel countersink set covering a head diameter range of 1/16 inch to 9/16 inch. Each countersink features a straight shank, a 90-degree included angle, and a 45-degree centerline angle for producing clean, accurate countersunk recesses in a variety of materials. The bright, uncoated finish is standard for general-purpose HSS cutting tools. This set is suited for machinists, fabricators, maintenance technicians, and trade professionals who need a ready-to-use assortment for countersinking and deburring work on the bench or at the job site.

The SC50905S set is intended for countersinking and deburring applications across metal fabrication, mechanical assembly, and general maintenance environments. Each tool cuts right-hand with a single-end design and no pilot, allowing direct use in a drill press or hand drill on ferrous and non-ferrous materials. The set stores in an included plastic case for organized access on the job. This assortment covers the most common countersink sizes encountered in fastener-seating and edge-prep work.

Installation Notes

Secure the countersink firmly in a drill chuck before use and verify the shank is fully seated. Power down and de-energize any machine before changing tooling.

Eye protection and appropriate PPE should be worn during all cutting and deburring operations.
