Frequently Asked Questions

What is an APPROVED VENDOR 82° countersink used for?

This carbide 3-flute countersink creates a smooth 82° chamfer around a pre-drilled hole, allowing a flat-head screw to sit flush with the workpiece surface. It is commonly used in metalworking, machining, and assembly applications across industries such as automotive, aerospace, and general fabrication.

What are the specifications of the APPROVED VENDOR 421517 countersink?

The APPROVED VENDOR 421517 is a carbide threaded-shank three-flute countersink with an 82° angle, a 1/2 in body diameter, and a 1/4"-28 shank thread size. It is designed for precision chamfering and deburring in rigid setups, compatible with standard threaded holders.

How to select the correct countersink for a flat-head screw?

Match the countersink angle to the screw head angle—82° is standard for inch flat-head screws. Ensure the body diameter exceeds the screw head, and the shank thread size (1/4"-28 for this APPROVED VENDOR model) fits your holder. Carbide construction provides durability in harder materials like steel or stainless steel.
