The Dormer deep hole spiral drill DIN 1869 / 3 Type W A978 is a highly advanced tool specifically designed for drilling deep holes in various types of steel. With a nominal diameter of 6.35 mm and an overall length of 350 mm, this drill offers an exceptional cutting length of 235 mm, allowing for precise and efficient drilling up to a depth of 25xD.
