Promat Flat countersink DIN 373

The Promat DIN 373 countersink is a high-precision tool specifically designed for machining core holes. Equipped with a cylindrical shank and a fixed guiding pin, this countersink allows for burr-free and chatter-free sinking of cylinder head screws, hex screws, and nuts. The 180-degree countersink angle ensures optimal adaptation to various screw types. The countersink is ideal for processing steel, cast iron, as well as non-ferrous and light metals, delivering excellent results at low cutting speeds. The three-flute design guarantees uniform and efficient material removal, enhancing productivity during use. The use of high-quality HSS material ensures durability and reliability in application.
