High-speed steel drill Ø7.40 OSG 1010740 is machined from a block of HSS steel that forms many cutting grooves with different cutting angles, the cutting angle will change between the cutting teeth.
High-speed steel drill bit has 3 main parts: tail, body and cutting blade. All three parts are identical, allowing for sharpening if the drill is worn for reuse.
Tail: The OSG high-speed steel drill tail is usually a clip-on tail that is firmly attached to the drill
Body: The connection between the tail and the cutting blade has uniformity in material, hardness...
The cutting blade: forged at a temperature of 1500 so the high-speed steel drill blade is sharp and easy to cut.
High-speed steel drill is made from solid high-speed steel so it can drill and process on metal surfaces up to 900N/mm2 (<50HRC)
