The drills are coated with a dampfin surface treatment to enhance durability and reduce built-up edge, and comply with DIN 338 standards. Suitable for use with standard drill chucks and drill presses, they are appropriate for both hand and machine operation in many general engineering applications. Overall, the A100 is sized at 1.3 mm diameter and 38 mm in length, offering a defined cutting length and spiral length for predictable performance.
