China Hard rock drilling bits size 32mm 34mm 7 Degree tapered button bits for mining
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.

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.
