Geologic Exploration Forging Reverse Threaded Drill Bit for RC Drilling Hammer
Reverse Circulation (RC) Drilling Bits 115mm , 140mm , 165mm with RC drilling hammer for mining Exploration
Introduction
HRC series reverse circulation DTH Hammer is the latest developed products of our company. It is mainly used for deep exploration drilling and stope ore grade control.
This reverse circulation drill bits are widely used in the following applicaiton field: Geologic exploration samples, Oil wells and ore mining, etc. And it\'s specifically designed to work with RC Hammers.
Characteristics:
1.Based on previous experience of ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth and continuous sampling.
2.The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.
3. The collection tube adopts an integrative design and can be replaced without disassembling the hammer. With carburizing treatment, it has good abrasive resistance.
4. Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer can drill holes of different sizes ensuring that the sample is not contaminated.
5. In different conditions such as loose soil, hard rock and plenty of water exists, sampling can be done well.
Features:
1) Face design: flat, convex, concave
2) Inserts design: spherical, ballistic, parabolic
3) Typical bit model: RE545, RE547
4) Bit diameter: 90mm to 213mm
5) Reliable quality
6) Long service life
7) Smooth flushing effect
8) Designed to work with RC hammers
