The Gandtrack Diamond Grit Countersink with Straight Shank is designed for roughing, grinding, and precision preparation of holes in carbon fibre and composite materials. Featuring a high-quality diamond abrasive coating on a HSS body, this tool delivers chip-free material removal and precise hole conditioning, making it ideal for pre-finishing operations prior to PCD tooling.

Engineered for controlled grinding rather than cutting, the diamond grit countersink produces smooth, accurate chamfers and countersinks, eliminating fibre breakout and surface damage. This makes it the perfect solution for aerospace, automotive, and advanced composite manufacturing where surface integrity and hole quality are critical.

Available in 44–60 grit standard, with custom grit sizes, angles, and geometries available upon request, the tool can be fully tailored to suit your exact application requirements.
