Value Collection SC5090D3 Countersink 90 Degree Hss

Product Description

The VALUE COLLECTION SC5090D3 is a single-end countersink designed for countersinking and deburring operations in metal fabrication, machining, and general trade work. Built from high-speed steel (HSS) with a bright uncoated finish, it operates at a 90-degree included angle and 45-degree centerline angle, making it suited for standard fastener seat preparation. The straight-cylindrical shank measures 0.5 inches in diameter for secure chuck engagement. With no flutes, this countersink relies on its geometry for cutting action, which reduces chatter and works well on softer metals and plastics. Right-hand cutting direction follows standard drill press and hand-held power tool operation.

This countersink covers a cutting diameter range from 0.1875 inches (3/16) minimum to 0.78125 inches (25/32) maximum, making it versatile across a range of fastener sizes. It is well-suited for residential and light commercial applications including sheet metal work, woodworking with metal inserts, and general fabrication where countersunk fastener seats are required. Machinists, maintenance technicians, and skilled tradespeople working with drill presses or hand drills will find this tool fits standard workflow without additional pilot requirements.

Installation Notes

Installation and use should be performed by a qualified machinist or tradesperson familiar with cutting tool safety. Always secure the workpiece before operation and set drill press speed appropriate to the workpiece material and tool diameter. Inspect the cutting edge before use and replace if chipped or dull. Do not exceed the tool's rated cutting diameter range.
