The Ruko-215035 twist drill is a set of 10 high-precision drill bits made of cobalt alloy high-speed steel (HSS-Co 5). This material provides superior heat resistance and exceptional hardness, making them ideal for drilling difficult-to-machine materials. Their design includes a tapered point grinding with a split point, conforming to DIN 1412 C, which facilitates drilling starts and improves accuracy.
With a cutting angle of 130° and a spiral angle of 20-30°, these drill bits are designed to deliver optimal performance in a variety of industrial applications. The golden-brown surface not only provides an aesthetic finish but also contributes to the product's durability.
The right-hand cutting edge ensures efficient and effective operation during the drilling process.- Material: Cobalt alloyed high-speed steel (HSS-Co 5)
