Drop Center R32 76mm Button Bit with Straight Retrac Body Thread Button Drill Bit for Geological Exploration
Our drill bit is made from top quality steel and tungsten carbide as same as internationally well-known brand and apply “hot-insertion” processing procedure to insert the buttons as same as internationally well-known brand.
Product Description:
Retractable drill bit mainly used in rock with gap, and the rock formation changeable, it’s mostly take drop center face with retract design, and it’s more easily to disassemble the rods & bits.
How to choose the bit tooth type:
Spherical buttons: The height of exposed teeth is low, mainly used in the very hard rock formation above F14, to improve wear resistance, to prevent the situation of debris, it should take lower drilling speed.
Ballistic buttons: It can expose more height of buttons, mainly used in soft rock and ordinary rock below F12, with quicker drilling speed, but encountered hard rock, very easily to happen buttons debris phenomenon.
