BBC 16W Pusher Leg Drill by Atlas Copco

BBC 16W Pusher Leg Drill by Atlas Copco

The Atlas Copco BBC 16W Pusher Leg Drill is a pneumatic underground rock drill built for drilling in drift driving, tunneling, mining, stone work, and other hard rock applications where reliable penetration and manageable tool weight matter. This model is part of Atlas Copco’s medium-range pneumatic rock drill lineup and is designed for water-flushed pusher leg drilling in small cross-section tunnels and headings. Atlas Copco lists the BBC 16W for hole diameters from 1 inch to 1.6 inch, with a standard 7/8 inch x 4-1/4 inch hex shank size.

The BBC 16W is often referred to as the Puma, and for good reason: it is an all-around rock drill built for strong performance in medium to hard rock without moving into a heavier drill class. It combines a long 2.17 inch stroke, 2.76 inch piston diameter, and 2,340 blows per minute impact rate to deliver the striking power needed for production drilling, development work, and general underground drilling tasks.

Built for Underground Rock Drilling

The BBC 16W is designed for crews that need a dependable pusher leg drill for tough drilling conditions. Atlas Copco’s own product information describes these water-flushed, pusher leg mounted rock drills as intended for driving drifts and tunnels with a small cross section. That makes the BBC 16W a strong fit for underground work where space is limited, drill control matters, and tool durability is not optional.

This model is especially useful for:

• Drift driving and tunnel development
• Underground stone drilling
• Mine development drilling
• Small cross-section tunnel work
• Medium to hard rock applications
• Pusher leg drilling with compatible Atlas Copco feed legs
• Water-flushed drilling where dust and cuttings removal are important

The 57 lb listed product weight keeps the BBC 16W in a practical operating range for underground use while still giving the operator real impact performance. The Air Compressor Store listing identifies this configuration as SKU 8311040110 with a 146 CFM maximum air requirement and 7/8 inch x 4-1/4 inch chuck.

Why the BBC 16W Works

A good pusher leg drill has to balance penetration, air demand, weight, and durability. The BBC 16W is built around that balance. Its long stroke helps produce good penetration in hard rock, while the rifle bar rotation mechanism is built to handle continuous drilling loads. Atlas Copco literature describes the BBC 16W Puma as an all-round rock drill suitable for most drilling applications in medium to hard rock, with pusher leg control placed in the back head of the drill for operator access.

The BBC 16W also stays efficient enough for job sites where compressor capacity matters. At 146 CFM, it can be matched with properly sized portable air systems while still delivering the impact rate needed for production drilling. For crews already using Atlas Copco pneumatic drilling equipment, the BBC 16W also keeps the setup familiar, serviceable, and compatible with common drill steels, bits, lubricators, hoses, and pusher leg arrangements.

Technical Specifications

Common Operating Advantages

1. Strong penetration in medium to hard rock
   The BBC 16W’s long stroke and rifle bar rotation make it a solid choice for hard rock drilling where consistency matters.
2. Practical underground handling
   At roughly 28 inches long with a compact pusher leg drill layout, the BBC 16W is suited for confined underground headings and tunnel work.
3. Water-flushed drilling
   The water-flushed design helps move cuttings out of the hole and supports cleaner drilling in underground environments.
4. Proven Atlas Copco platform
   The BBC 16W belongs to Atlas Copco’s long-running pneumatic rock drill family, with published specifications, replacement parts support, and compatible accessories available through the Atlas Copco ecosystem.

Compatible Pusher Leg Use

The BBC 16W is designed to be used with a compatible pusher leg. Atlas Copco literature lists BMT 51, ALF 71, ALF 71-1, and ALF 67/80 as suitable pusher leg options for the BBC 16W and BBC 34W family. Pusher legs are typically selected based on required feed length, working height, and the drilling setup.
