T51 102mm Retractable Blast Hole Drill Bits , Ballistic Rock Mining
Tools Retract Button Bit
Description:
MTH thread button drill bits are made by high quality alloy steel
bar and tungsten carbides. Through heat treatment, our drilling
tools are tough enough to meet rock drilling demands and have the
least loss of energy while drilling the rocks. Besides, we can
design customized thread button drill bits according to different
drilling application, and custom drill bits are applicable to drill
soft rock, loose-medium rock and hard rock.
Rock Drill Thread Button Bits is suitable for R22, R25, R28, R32,
R35, R38, T38, T45, T51, ST58, T60 rock drill rods use. It have
many thread. It's widely used for hard rock(f=8~18) drilling use.
Specification:
A comprehensive range of various button bits shown as below:
Thread sizes: R25, R28, SSR28, R32, SSR32, R35, SSR35, R38, T38,
T45, T51, SST58, SST68, SGT60;
Head diameters: 64mm ~ 127mm;

Features:
1.The longer life of the drill: the alloy material, with longer
using life which better than the similar products.
2.High Drilling Efficiency: the drill buttons is wear-resistant, so
that the drill can always keep sharp, thus greatly improving the
speed of the drilling.
3.The drilling speed is stable: the bit is scraped and cut to break
the rock.
4.Good Performance: the has strong wear resistance, good diameter
protection and can make the cutting teeth be used efficiently.
