6" DTH Hammer - VD60D x 148

6" High Pressure DTH Hammer - VD60D x 148

The VD60D x 148 is a 6 inch high pressure down the hole hammer built by Vikay Mining Equipments in India. It matches the VD60S x 148 on size and weight, 148 mm outer diameter and 94 kg over 1,140 mm, but takes the DHD 360 bit shank instead of the SD-6, so specify it where your existing bit stock is DHD. The coupler is 3 1/2 inch API regular pin, it takes bits of 6 1/2 inch and above, and runs on 350 to 940 cfm at 150 to 350 psi.

VD60D x 148 DTH Hammer FAQs

Will the VD60D x 148 fit my drill string?

The VD60D x 148 uses a 3 1/2" API coupler thread, so it fits any string cut to that thread. Check the thread on the string already in use before ordering, because that is what decides it rather than the hammer size.

What hole will the VD60D x 148 drill?

The VD60D x 148 is 148 mm across, 1,140 mm long and 94 kg. It is a 6 inch hammer, so it is matched to a 6 inch hole and fitted with a bit of that size.

Which size of DTH hammer do I need?

This page is the VD60D x 148, a 6 inch hammer, 148 mm across and 94 kg. The size is the hole. Vikay manufactures 4 inch, 5 inch, 6 inch, 8 inch and 10 inch down the hammers, and the hammer is chosen to match the hole diameter being drilled, then fitted with a bit of that size. The larger hammers need proportionally more air, so the compressor on site is the practical limit on how big a hole can be drilled.

What air pressure does the VD60D x 148 need?

The VD60D x 148 works at 150 to 350 psi. Down the hole drilling is volume hungry, so on most sites it is the compressor that limits the hole, not the hammer.
