Our Advantages:
1.higher hardness,higher wear resistance,higher toughness,better deflection and fracture resistance,results in a long life and good size accuracy
2.Abundant tool choices,suitable for every aspect of today's routing work requirements
3.Critial quality inspection control under the criteria of ISO
Tapered button bits are the most popular tapered drill bits with a wide selection of head diameters from 26mm to 48mm. With carbide buttons hot pressed on the bit skirts, tapered button bits have a good drilling performance and are excellent in longevity.
