Diamond impregnated mining bits

Surface set diamond mining bits

These tools have one layer of natural diamonds with an exposure of approx. one third of their diameter.

Different bit profiles, diamond qualities and diamond sizes are available. Also face discharge and TC reenforced waterways and bit bodies are available.

Bit profiles:

W-profile (semi flat profile)

BY-profile (full round profile)

S-profile (step profile)

P-profile (pilote profile)

M-profile (modified semi flat profile)

D-profile (double tapered profile)

E-profile (profile with long outer taper)

BN-profile (profile with short outer taper)

Konkave-profile (profile with inner taper)

Diamond qualities:

WAA1 (standard, F-quality, A)

SELECT (X-quality, AA)

PREMIUM (AAA)

CARBONADOS

Diamond sizes:

6 stones per carat

8 stones per carat

10 stones per carat

10/15 stones per carat

15/20 stones per carat

20/25 stones per carat

30/40 stones per carat

40/60 stones per carat

as well different sizes in between

Diamond impregnated mining bits

These tools have a metall coated, top quality synthetic diamond grit embedded in the erosion matrix which is adapted in hardness to the material to drill.

As standard three different impregnation heights are available: 4, 6 and 7.5 mm.

Two profiles are available. These are the flat profile and the V-profile with radial slots in front of the cutting area.

Standard is a diamond concentration C 50 (= 2.2 ct/cm³).

Matrix hardnesses:

SS (very soft, colour code yellow)

S (soft, colour code black)

SH (soft - medium hard, colour code green)

MH (medium hard, colour code gold)

MH/EH (medium hard - extra hard, colour code silver)

EH (extra hard, colour code blue)

EEH (super hard, colour code red)

Stratacut (PCD) mining bits

Stratacut bits are designed for maximum core recovery and penetration rates in soft to medium formations. They are particulary applicable in soft, sticky formations where performance of large stones diamond bits may be marginal. Stratacut non coring bits have best results in underground drilling. Stratacut tools can economically replace TC tools.

The stratacut cutters have a thin layer of polycristalline synthetic diamonds bonded on a tungsten carbide backing. They are embedded in a tungsten carbide matrix.

Synset (TSD) mining bits

Synset bits utilize a new type of thermally stable, selfsharpening, synthetic, polycrystalline diamond setted in a tungsten carbide matrix.

The synthetic diamond cutter is positioned for aggressive shearing and plowing action and maximum drilling live in medium to hard formations.

TC mining bits

TC bits have octagonal TC inserts which are fixed at an angle of 10° to form the cutting edges. The quality of the TC chosen has been especially developed for rotary drilling to give high wear resistance.

The TC inserts can be reground, thus high penetration rates can be maintained throughout the entire service life of each bit.

TC bits are normally used for coring in softer rock formations, for overburden drilling and for cleaning drill holes.

Another type of TC bits which are borit bits are also available. They are manufactured with crushed TC with a granular size of 3 - 6 mm, mixed with a special alloy.

Borit bits cause less vibrations, offer better core recovery than standard TC bits and allow to washover steel.

Reaming shells for mining

Reaming shells are necessary for most core barrels.

They can be blank. But mostly they are set with TC or diamonds. In that case they keep the accurate diameter of the hole and stabilize the core barrel.

Diamond set reaming shells are available as ring-type or spiral-type versions. Additional to all diamond qualities for bits also the diamond quality WAA2 (economy, D-quality) is available for reaming shells.

Diamond reaming shell for mining, ring-type

All a.m. tools are available for all core barrels in all sizes, no matter if the core barrels are DCDMA or ISO standard. Also tools for wireline core barrels are in our range.

Non standard tools with non standard diameters or other unusual specifications are no problem for us.

We are also able to produce tools for which we do not have drawings if you send us a drawing or a sample.

Beside a.m. tools we also produce different additional drilling equipment such as spare parts for core barrels, single tube core barrels, double tube core barrels, triple tube core barrels, liner conversion kits for double tube core barrels, drill rods, wireline drill rods, casing tubes, hole openers, window mills, etc...
