VK 12T Pneumatic Rock Drill

Light Weight Rock Drill – VK 12T ( 22 lb )

The VK 12T is an 11.1 kg hand held pneumatic rock drill, technically equivalent to the Atlas Copco BBD 12T sinker. It is the T handle version of the VK 12D, configured for vertical drilling to about three metres, and it uses 39 l/s of air at 2,580 blows per minute through a 22 x 108 mm shank. The extra air and the two handed T grip suit sinking and down hole work where the drill carries its own weight.

Features

• Light weight for easy handling

• Built-in air-flushing gives faster blasting cycles

• Robust kick-latch retainer - change steels quickly and easily

• Spring-dampened handles reduce vibrations

VK 12T Rock Drill FAQs

Can the VK 12T replace a BBD 12T?

Yes, that is the duty it is made for: the VK 12T is technically equivalent to the Atlas Copco BBD 12T. A 45 mm piston on a 40 mm stroke gives 2,580 blows a minute at 11.1 kg on 39 l/s of air at 6 bar. It takes the same 22 x 108 mm shank, so drill steel already on site will fit.

Will Vikay parts fit my BBD 12T?

Yes. Vikay manufactures the VK 12T, which is technically equivalent to the Atlas Copco BBD 12T, and the replacement parts alongside it. The same parts serve both, so both can be supported out of one parts stock. The listing, with part numbers and the assemblies they belong to, is on the BBD 12T01 Atlas Copco Rock Drill Parts page.

Which Vikay rock drill do I need?

This page is the VK 12T at 11.1 kg, at the light end of the range. Four are manufactured and the hole decides between them. The VK 12D and VK 12T are the light sinkers at 9.8 and 11.1 kg, D handle for horizontal and plug hole work, T handle for vertical holes to about 3 metres. The VK 65 at 25 kg is the bench and secondary drilling machine, and the VK S215 is the pusherleg drill for blast holes in narrow vein stoping.

Will my compressor run the VK 12T?

The VK 12T needs 39 l/s at 6 bar (83 cfm at 87 psi), delivered continuously. The inlet is 19 mm, so run at least that hose bore: anything narrower throttles the machine before the compressor does. At 2,580 blows a minute the draw is constant rather than intermittent, so allow headroom for hose length and for worn couplings.

Will my existing drill steel fit the VK 12T?

The VK 12T takes a 22 x 108 mm shank (7/8 x 4 1/4"), with 19 x 108 mm available as an option, so any drill steel cut to that shank fits, whatever machine it came off. If the shank does not match, the tools are the cheaper thing to change.
