Tungsten Carbide Button Bits/Rock Drilling Tool/rock drill bits for
tunneling and drifting drilling
Tapered Quarry Button Rock Drill Bits 40mm 41mm 45mm With higher
strength of tungsten carbide as the body, the bit has good
anti-erosive and the increased the toughness.
With premium PDC cutters, the bit has enhanced reliability and
drilling efficiency.
Suitable formation:Medium hard to hard, solid hard rock formations
We manufactuer various tapered button bits in different degrees as
below:
Bit diameter: 32mm ~ 48mm;
Tapered degree: 4°46', 6°, 7°, 11°, 12°;

For drilling medium-hard to hard and abrasive rock formations,Taper
angles of 11 and 12-degrees are
normally used on modern drill rigs, like YT28B, YT29A, Y24, YT24,
Mobile rock drill pneumatic and hydraulic.
For low impact rock drills and softer rock formations, a narrow
tape range of 7 degrees is used, such as
Indian, Saudi's granite and marble quarry.
A comprehensive range of taper button bits, cross bits and chisel
bits with 6, 7, 11, 12 degreetaper.
1 Long life
2. Lower consumption
3. Wide selections of drill bits
4. Delivery quickly
5. Suitable for small hole range
6. Widely used in Dimensional Stone Quarrying Industry
7. Widely used in Underground Mining Industry
We can supply long skirt and short skirt taper button bits.
Comparing with tapered chisel bits and tapered cross bits, button
bits has higher technology, much longer primary drilling time and
higher drilling efficiency, so that the button bit is popular among
the users. Tapered equipment affords drillers the ability to change
drilling bits whilst still using the same drilling rod. Drillers
choose tapered button bits for faster drilling penetration rate.
Different taper sizes have different characteristics when it comes
to the "knock-off" index – the smaller angle will prevent the bit
from spinning.
