2021 Bestlink T51 Threaded button bit, top hammer tools, underground mining, drift and tunneling, Thread Button bits Made with high quality of best quality alloy steel bar and tungsten carbide, through heat treatment like Atlas.

11-5/8inch IADC 537 Tricone Roller Bit with Tungsten Carbide Insert TCI Tricone Roller Bits Bestlink offers a full line of tricone and bicone bits. Tricone drill bits are available in new and used (re-tip and re-run) steel tooth and tungsten carbide insert, size from 3 3/8”(85.7mm) to 26”(660.4mm) for use in all formations, with any bearing/seal type, and a wide range of additional custom features.

STEEL MILLING TOOTH BITSIADC 1 SERIES DRILL BITSThese bits are used to drill low-compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hardfacing is used to control tooth wear. On the soft

Big Hole Drill Bits Down The Hole DTH Hammer Bits 1, valveless air distribution. More reliable. 2, simple design of the piston, long life. 3, More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption. 4, fewer internal parts, simple structure, longer life, less failure and easier to maintain becayse all the parts are heat treated. 5, It is easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
