Our spot drill offers you the opportunity to get in a precise position of your choice. With the grounded process, you can easily achieve the perfect angle. This spot drill bit is carefully crafted using premium grade DIN materials, that are created in small batches to ensures perfection.
These come with an increased carbon, molybdenum, and tungsten content that automatically ensures a high carbon saturation, making sure you receive a superior material spot dill. Moreover, the spot drill goes through a high-speed steel heat treatment technology, which includes slow heating and rapid cooling technology. Making sure you can easily get great use out of these drill bit in different temperatures.
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.
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 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.
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.
