1 = drilling bit

2 = extension tube

3 = head, standard thread 1-1/4" UNC

4 = core lifter

As standard all tubes are available in usable lengths of 500 and 1000 mm. Other lengths on request.

Without special note on the order all bits are manufactured as diamond impregnated bits in standard version. Also diamond impregnated bits in mining version, surface set diamond bits, TSD bits and TC bits with TC pins or crushed TC are available.

Diamond impregnated bits are available in seven different matrixes. All bonds are free of cobalt.

Diamond impregnated bits in standard version are manufactured like thick kerf, ringsintered concrete bits type 8000, which means that they have a 9 mm impregnated diamond ring, 7 mm high waterways just in front of the ring and no further gage protection. The diamond concentration is C 35 and a fine diamond grit is used.

Diamond impregnated bits in mining version are manufactured like mining bits, which means that they are 6 mm impregnated. There diamond ring has a overall height of approx. 15 mm. The waterways are 9 mm high in front of the ring. The inner and outer gage also have waterways. The gage is made of a ultrahard matrix and is diamond and TC protected. The diamond concentration is C 50 and a coarse grit is used.

All bits are available for air flushing (dry drilling). In that case we recommend the use of our swivel for air flushing.

Extension tube, head and swivel for air flushing, as well as fitting bits (diamond impregnated in mining version, setted with TC pins, surface setted with diamonds)

Extension tube, head and swivel for air flushing (with bits)

Swivel for air flushing with 1" free open area.

For using this swivel heads with NW box thread are needed. The swivel has a 1-1/4" UNC box thread as connection for the machine.

Full grip wrenches for screwing and unscrewing of extendable drilling systems.

The design of these wrenches allows jointing and breaking of thin walled tubes and bits without risk of damage. These wrenches should be used in pairs.
