VK 46 WR-8 - Stopper Drill
The VK 46 WR-8 is a 41 kg stopper drill, technically equivalent to the Atlas Copco BBD 46WR-8. Stoppers drill upward, and this one is configured with clockwise rotation for tightening nuts and roof bolting in underground mines. A short piston stroke gives high penetration rates in soft and medium hard rock, and it runs on 120 cfm of air. The 1,820 mm feed leg carries the machine against the back so the operator does not.

VK 46 WR-8 Stopper Drill FAQs
What is the difference between the VK 46 WR-8 and the VK 46 WS-8?
This page is the VK 46 WR-8, the bolting version, at 41 kg. Both are stopper drills that work vertically or on an incline, on the same body and the same air. The WR is geared for tightening nuts and installing bolts overhead; the WS is for production drilling, raise driving and stoping.

Will my compressor run the VK 46 WR-8?
The VK 46 WR-8 needs 120 cfm, delivered continuously. Size the compressor against that figure rather than against a peak.
What hole size does the VK 46 WR-8 drill?
27 to 40 mm holes as a rule, and up to 64 mm for a single hole. The standard chuck takes a 22 x 108 mm shank, so drill steel is ordered against that rather than against the model.
How far does the VK 46 WR-8 extend?
The leg has 930 mm of feed, going from 1,820 mm retracted to 2,750 mm extended. That range is what sets the back height it can work under, so check it against the heading before ordering.
