Manufactured in Australia from premium HSS for durability and precision performance.
 
This precision countersinking cutter is designed to countersink holes at 100° angles with a smooth radius between the hole and the chamfer. The radius ensures rivets seat evenly along the full surface, preventing damage from sharp edges and improving the overall fit and seal.
 
Ideal for hard or abrasive materials, it features a 3mm through-hole for easy mounting or removal from fixtures, and a 1/4"-28 male thread, making it compatible with all countersink or microstop cages with a female 1/4"-28T.
 
We also offer a professional sharpening service, allowing you to extend the life of your cutters and reduce tooling costs.
