button bit product details:
Bit face shape selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
2. Concave Face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control 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 air pressures 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.
1. Product Name: dirlling button bit, thread button bit, button drilling bit
2. Application: Thread button bits made with high quality of best quality alloy steel bar and tungsten carbides, 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
3. Feature: button bit can achieve hardness under strong rock drivage, and the reduction in minimum energy loss in the process of transfer, solid and uniform not easily drop tooth and tooth, tooth force so that the impact energy can be concentrated on the rocks, achieve the goal of efficient tunneling.
4. Material: High quality carbide and high quality steel
5.MOQ: No requirement for testing and trial order
