Product Description
Rock drilling thread button bits are widely used in all kinds of mining, drilling, quarrying, engineering, construction, water well drilling, oil exploring industries etc.
Our thread button bits are made with high quality of best quality alloy steel bar and tungsten carbides with superior wear resistance and impact toughness superior, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy.

Key specifications/special Features:
Bit face shape selection.
1. Drop Center Bit
For hioh penetration rates in soft to medium hard and fissured rock formations, Low to medium air pressures. Maxumum hole
deviation control.
2.Concave Face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviationcontrol and good flushing capacity.
3.Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. it is the most resistance to steel wash.
and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high airpressures and good resistance to steel wash step gauge bit.
5. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures.
Good penetration rates an resistance to steel wash.
Advantage
1. High Quality
2. Reasonable Price
3. High Efficiency
4. Delivery On Time
Application
The button bit is widely used for rock drilling, blasting holes and other drill works in quarries, coal mines,
road and dam constructions and other similar projects.
