Product Description

UltraMatrix Core Bit HQ3 Double Height Diamond Layer Imprenated Diamond Core Drill Bit
The impregnated diamond bit is used for cutting holes in medium to ultra-hard formations. The crown is made up of a metal powder and diamond matrix that wears away during the drilling process and exposes new layers of diamonds, renewing the cutting points. The combination of diamond and proprietary matrix result in the optimal performance of a Roschen™ impregnated bit.
New Stage Diamond Coring Bits:
Roschen has a well known history of innovation and the Stage
waterway design pushed the envelope by allowing then tallest crown
height in the industry. With a continued focus on our customer, Roschen have
never stopped improving our patented design. 

Roschen bits are available in all standard drilling sizes as well as a number of region-specific sizes.

Crown Height: 
Roschen offers three different crown impreg depths of 6mm, 9mm, 12mm, and 25mm (with the patent-pending Stage waterway). The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance.

Roschen bits are available in four standard gauge configurations:

Standard gauge (S)
Equal to reaming shell gauge (R)
Less than reaming shell gauge (-R)
Oversized OD (OS, INCHES)

Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.

Matrix bond: 
Roschen impregnated bits matrices can be ordered in Standard, Abrasive, and Competent formulations.  Abrasive bits are for broken, abrasive drilling conditions or for harder rock with broken, abrasive conditions. Competent bits are free-cutting for fast penetration in very hard, competent rock or for use on lower-powered rigs and in geo-technical applications. 

Roschen recognizes that drilling conditions are often encountered where formations change repeatedly within a very short interval. Under such circumstances, the lowest bit which will cut the hardest of the expected formations is recommended, and some discretion should be exercised to restrict penetration rates in any abrasive rocks encountered to protect the bit from excessive wear rates. However, if hole deviation becomes a problem, a higher bit, combined with reduced penetration rates, may contribute to bringing it under control.
