VD50S x 106 DTH Hammer FAQs

Will the VD50S x 106 fit my drill string?

The VD50S x 106 uses a 2 3/8" 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 VD50S x 106 drill?

The VD50S x 106 is 106 mm across, 980 mm long and 44 kg. It is a 5 inch hammer, so it is matched to a 5 inch hole and fitted with a bit of that size.

Which size of DTH hammer do I need?

This page is the VD50S x 106, a 5 inch hammer, 106 mm across and 44 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 VD50S x 106 need?

The VD50S x 106 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.
