BBC 16W - Jackleg Drill

Even with relatively low air consumption, the BBC 16W delivers high impact, and paired with the correct pusher leg, it's a cost-effective drilling unit that doesn't compromise on production.

Key Features

• High penetration rate — drills efficiently across medium- to hard-rock

• Rifle-bar rotation mechanism — the same reliable rotation system used across the popular jackleg drill range, giving consistent bit rotation under load.

Where is the BBC 16W Pneumatic Jackleg Drill Used?

The BBC 16W is also known as the perforadora PUMA BBC 16W in the Peruvian market. After the Boart Longyear Seco 250 Drill (RMT 250), BBC 16W is one of the most popular drills used in Peru.

It comes with the standard shank of 22 x 108 mm, similar to SECO 250. Thus, similar rock drilling tools can be used in both the tools.

• Underground Mining

The BBC 16W is used for both development drilling (advancing new headings and drifts as a mine expands) and production drilling (drilling blast holes in established stopes to extract ore).

Its higher blows-per-minute rate makes it well suited to the repetitive, high-volume drilling that production work demands.

• Metal Mining

In narrow-vein metal mines (gold, silver, copper, zinc, and similar deposits), headings are often too tight for larger rigs. Thus, hand-guided jackleg drill like the BBC 16W become the practical choice.

Its ability to handle medium-to-hard rock matters here, since metal-bearing veins are frequently harder and more abrasive than the surrounding host rock; thus, it requires a drill that maintains penetration rate without excessive wear.

• Tunnelling

For tunnel and drift construction, the BBC 16W is used for horizontal and angled blast hole drilling as the tunnel face advances. This includes civil tunnelling projects as well as mine access tunnels and drifts. Paired with a matching pusherleg, the drill provides the steady, hands-guided control needed to keep holes accurately aligned along the tunnel's planned profile — important for controlling overbreak and keeping the tunnel to its designed dimensions.

Why Choose the BBC 16W

At 2,340 blows per minute, the BBC 16W drills faster than the lighter RH 656 4W (2,040 bpm). Though it is a bit heavier in comparison to the RH 656W (28.5 kg vs 22 kg) for stronger impact — a reasonable choice where medium-to-hard rock needs more consistent penetration.

RMT pairs the BBC 16W with the BMT 51 or RMT 71 pusherleg, giving you a matched, ready-to-work drilling combination rather than having to source components separately.
