Diamond Adjustable Stop Countersinks

Diamond Adjustable Stop Countersinks are precision tools engineered for accurate and repeatable countersinking operations on hard materials including ceramics, carbide, glass, composites, and metals. Featuring a hardened adjustable stop collar and high-quality diamond cutting edges, these countersinks deliver superior surface finish and consistent depth control. The adjustable depth stop minimizes over-cutting and ensures uniform chamfer dimensions part-to-part — ideal for aerospace, optics, semiconductor, and medical machining applications. With exceptional wear resistance from industrial diamond, these countersinks maintain edge integrity under extended use. They are compatible with standard collets and tools holders for easy setup. Whether deburring, chamfering, or preparing screw seats, Diamond Adjustable Stop Countersinks provide dependable performance, precision, and long tool life. Optimize your manufacturing process with a countersink that combines accuracy, diamond durability, and adjustable depth control.
