China 8mm Diamond Core Drill Bits for Stone Masonry and Construction

Product Description

China jinshi crown height 8mm diamond core drill bits for stone 

>> Introduction

The impregnated diamond bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer of the ZM contains a uniform distribution of these crystals that are embedded in a powdered metal bond. 
The matrix of our impregnated bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action. 
Our impregnated bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.

>> IMP Diamond Bits Structure

Performance of IMP bits is detemined by combination of diamond and matrix.Jcdrill uses special matrix that provides optimal performance.

1:Thread  Precision cut international standard thread 2:Bit Shank  Made of high quality steel and CNC machined 3:Core lifter case seat Supports core lifer case when breaking core 4:Tungsten carbide Protects integrity of the crown 5:Water way Coreols fluid flow around the cutting edge of bit 6:Profile Optimal design to ensure high drilling efficiency in different rock 7:Crown Available in a wide variety of formulations,the crown is cutting edge of bit

Matrix:
JCDRILL impregnated bits matrices can be selected by our engineer according to ground conditions at client's work site.

Threads:

Standard Q threads as well as thread types required by clients are available.
Crown Height:
JCDRILL offers crown impreg depths of  9mm, 12mm, and 16mm .The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance.The crown is formed with a mixture of metal powder and diamond matrix.matrix is wore away during the drilling process and new layer of diamond is exposed renew the cutting points.
Waterways:
Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.
