Small hole tapered ground bits are the most popular tapered bits available in head diameters from 26mm to 48mm. The cemented carbide ball teeth are hot-pressed on the skirt of the drill bit. The tapered ball tooth drill bit has good drilling performance and long service life.
We manufacture button bits in various degrees of taper, as follows:
Drill diameter: 32mm~41mm;
Taper: 4°46', 6°, 7°, 11°, 12°;
Shank Size: Hex. 19mm, Hex, 22mm and Hex. 25 mm;
Button configuration: 4 buttons, 5 buttons, 6 buttons, 7 buttons, 8 buttons

Material and production process details: Materials - We use 45CrNiMoVA and YK05 Tungsten Carbide to produce our taper drill bits, both of which are well known in the world for drill bit production. Advanced Technology --- The tapered button bits we produce adopt hot pressing technology, which is the most advanced technology for producing tapered button bits so far. |

Bits should be reground when the rate of penetration drops or when the carbide shows signs of damage A regular grinding program usually leads to good work habits. For example, drill bits can be inspected and then reground after a certain number of holes or at the end of a shift. Grinding too early is not necessarily uneconomical because there are fewer carbides to grind away. It is better to regrind than to lose productivity due to damage. Proper grinding can significantly extend the life of your drill bit. But just as importantly, it also improves the performance of the overall drilling operation, especially the straightness of the hole. |
