Main features of reduced shank drill bits:

1. Material: The only manufacturer in China who uses DIN materials in batches to increase the carbon, tungsten, and molybdenum content, thus ensuring high carbon saturation and superior material properties. HSS M2 Reduced Shank Twist Drill Bit for Drilling Metal

2. Adopt unique high-speed steel heat treatment technology, such as slow heating, rapid cooling technology, high quenching temperature, and tempering temperature technology, and ox nitridation technology to improve wear resistance and rust resistance.

3. Straight drill below 13mm adopts a fully ground process, which not only has a good finish but also can ensure the radial run-out of the drill bit within 0.03. Drilled holes are more accurate. Similarly, the taper drill uses the outer diameter of the CNC outer circle to ensure that the radial run-out of the taper drill is also within 0.03 mm. Nitride Finish HSS Reduced Shank Twist Drill Bit For Metal Stainless Steel Aluminium Drilling

4. The groove shape of the drill bit has combined the shape of the parabolic, which makes the drill bit stronger and the chip removal smoother.

5. Through the technical innovation of high-speed steel twist drill, the life of the drill bit of our factory is generally higher 50% than the mainstream products in the domestic market, reaching the service life of international famous brands.

6. The second generation of hss drill is not only suitable for the processing of general steel such as carbon steel, but also for difficult to machine materials such as die steel and stainless steel. HSS 6542 Reduced Shank Twist Drill Bit
