All of them have wonderful engineering and special designs, experts in powder metallurgy with sophisticated sintering and CNC machining, strict quality control and precise gauge protecting technology, all of those procedures are only for ensuring best work-life and good penetration rates, especially for MASTER bits, which are widely used in Mideast countries, Russia language speaking countries and South America for tackling tough rock conditions. Not only for impregnated diamond drill bits, but also we provide surface-set diamond bits, PDC bits, T.C bits for your selection and we are capable of designing the bits according to our customers specified requirements.

Diamond Drill Bits Crown Profiles & Waterway Configuration

CGET WUXI offers various range of different crown profiles and waterway shapes to meet different requirement according to rock conditions, all of the waterway configuration provide customized designs.

W Profile Standard Waterway (STD)

• Standard configuration with broad range of applications for general purpose diamond coring drilling.
• Best sellers on the market.

W Profile Ex-Wider Waterway (Wedge)

• Suitable for soft and broken, broken and abrasive formation where blocking of standard waterway is possible. 20% fluid capability if compare with “SW” type, higher circulation pump volumes is recommended for effective performance.
• Good fluid cooling of the bits and keep the waterways free of cutting
• Improve productivity. Reducing the surface of cutting area by 10% if compare to “SW” type.

W Profile Turbo Waterway (Turbo)

• Best suitable for competent rock, hard to very hard formations. High productivity with decreased pressure required on the bit, reducing the surface of cutting area by 15% if compare to “SW” type.
• Extended waterways is good for fluid circulation, remove the cuttings quicker and keep the waterways clean.
• Better penetration rates in most competent rocks, but not recommend for using in highly fractured formations.

W Profile Face Discharge Waterways (FD)

• Recommended for use when drilling with triple tube wireline core barrel systems for soft unconsolidated formations
• Minimum core sample wash, avoid the potential for undesirable core erosion

Regarding the profile of the impregnated diamond drill bits, flat profile is provided as well for your selection, contact our sales representative to know more.

Impregnated Diamond Drill Bits Selection Guide

There Are Five Critical Tips For Diamond Drill Bits Selection

* Tip 1: Rock hardness

Softer rock hardness, choose lower number bits

* Tip 2: Rock grains

Coarse grain size of rock always with abrasiveness, choose lower number bits; fine grains size of rock with slightly abrasive, or compete rocks, choose higher number bits.

* Tip 3: Waterways

“WW” profile is the general profile design, the appropriate selection of right waterways can help us to improve the penetration speed ( Refer to the above profiles and waterways)

Tip 4: Drilling rig types

Rig with low power(Portable or lightweight rigs), choose higher number bits;

Rig with powerful power( Hydraulic rigs), choose lower number bits.

Tip 5: Penetration rate & bit lifer

Slow penetration rate? Try higher number bits.

Short bit working life? Try lower number bits.

Recommendations for Drilling

The following basic guides will help you to understand the bits and realize good performance, as the drilling conditions and drilling equipment’s performance is vary too much, it is impossible to give a very accurate RPM.
