RUKO HSS double drill bits with self-centering, 3.25 mm diameter, pack of 10 units.

The Ruko-2520325 drill bit is a pack of 10 self-centering, ground, double-ended HSS drill bits designed to deliver exceptional performance in assembly work on thin-walled materials. With a diameter of 3.25 mm, these drill bits are shorter than those specified in DIN 1897, making them ideal for drilling sheet metal, flat iron, and metal profiles. Their robust construction ensures high resistance to breakage, allowing them to be used in hand drills and are reversible.

The advantages of the DIN 1412 C standard are reflected in their excellent centering and the low pressure required during use. The conical point grinding with a split point, along with a 118° cutting angle, ensures efficient and precise cutting.
