When a job calls for serious impact power—thick concrete, stubborn slag, hard-packed surfaces, or heavy industrial chiseling—a compact tool isn’t always enough. That’s where the B67C Pneumatic breaker hammer earns its place. It’s a classic jack hammer driven by compressed air, built with a simple, reliable impact mechanism and the kind of “steady hitting” feel operators appreciate on long shifts.
As a hand held jack hammer, the B67C uses compressed air to push the internal piston in a reciprocating motion, repeatedly striking the chisel (tool steel). The result is consistent impact energy for breaking, cutting, and chiseling across construction and industrial maintenance work—especially where electric tools are less practical.
Quick Product Overview (With the Specs Buyers Actually Compare)
Here’s the B67C data you provided—these numbers are exactly what experienced buyers look at when choosing a Pneumatic jack hammer:
Piston diameter: 50.75 mm
Piston stroke: 285 mm
Percussive frequency: 1400 b.p.m
Length: 615 mm
Air consumption: 2.0 m³/min
Air tube diameter: 19 mm
Shank size: 32 × 155 mm
Air inlet size: 3/4 (P/T)
In plain terms: the 50.75 mm piston diameter paired with a 285 mm stroke points to a tool designed for heavier breaking and deeper chiseling. And with 1400 blows per minute, it keeps output steady and predictable rather than “bouncing around” on the surface.
Where This Jack Hammer Typically Works Best
Based on the applications you shared for pneumatic breakers, the B67C Pneumatic jack hammer fits naturally in:
Construction & demolition: breaking concrete, removing damaged sections, opening work on brick/concrete walls
Roadwork & infrastructure: surface removal for repairs, trench access, bridge and traffic-project weld seam chiseling
Industrial maintenance: furnace/boiler work, slag removal, casting cleaning, deburring, and metal structure chiseling—especially tight or irregular surfaces
General breaking tasks: any site that prefers compressed-air tools for stability and simple maintenance routines
If your work is more “heavy removal” than “light trimming,” the B67C as a hand held jack hammer is the kind of model contractors typically shortlist.
FAQs Customers Usually Ask (And Clear Answers)
1) How strong is the B67C compared with smaller pneumatic breakers?
Start with the impact geometry: the B67C’s 50.75 mm piston diameter and 285 mm piston stroke are aimed at heavier work. Combine that with 1400 b.p.m, and you get a jack hammer that hits consistently and keeps moving material instead of just rattling the chisel.
2) What air supply do I need for this Pneumatic jack hammer?
The B67C is rated at 2.0 m³/min air consumption, so you’ll want a compressor setup that can comfortably supply that flow without starving the tool. When airflow drops, operators feel it immediately—impact becomes weaker and the tool feels “lazy.”
3) What hose size should I use?
Match the tool requirement: air tube diameter is 19 mm. Keeping the hose correctly sized helps maintain airflow and keeps the Pneumatic jack hammer striking the way it should. Also follow the practical rule from your operating guidance: don’t kink the hose into sharp angles—keep it straight or in a gentle bend to avoid pressure loss.
4) What chisel shank does the B67C take?
This model uses a 32 × 155 mm shank size. That’s the compatibility number to check before ordering chisels. If the shank doesn’t match, it won’t seat properly—bad for efficiency, worse for safety.
5) Why do pneumatic breakers fail early on some sites?
Most early wear comes from two habits:
Empty striking (blank hitting) when the chisel isn’t properly engaged with the work surface
Poor lubrication
Your maintenance notes are clear: pneumatic tools must be oiled. A good working rhythm is adding oil about every 2 hours (some crews stretch to 2–3 hours depending on duty), and always oiling before use and before storage.
6) How should we handle maintenance to keep the B67C reliable?
A simple routine goes a long way for a hand held jack hammer:
Oil before use, and re-oil during work (commonly every 2 hours)
Plan regular cleaning—many teams follow a weekly disassembly and cleaning practice (clean, dry, re-lubricate, reassemble)
If something feels off, don’t “field-repair” it on the spot—stop and send it for proper service (your safety rules strongly discourage random jobsite disassembly)
7) Any safety tips operators should not ignore?
A few that actually prevent injuries and downtime:
Check the work area for loose material and falling-debris risk before starting
Keep all connections tight—high-pressure joints should be secured properly (your rules mention using the correct clamp method rather than makeshift wire fixes)
Avoid driving the chisel so deep it gets stuck; if it jams, loosen carefully and clear surrounding material—don’t yank violently
Closing Summary
The B67C Pneumatic breaker hammer is a serious, jobsite-ready jack hammer for heavy breaking and chiseling. With a 50.75 mm piston diameter, a long 285 mm piston stroke, and a steady 1400 b.p.m impact rate, it’s built to keep material moving. It also stays practical on setup: 2.0 m³/min air consumption, 19 mm air tube diameter, 3/4 (P/T) inlet, and a 32 × 155 mm shank that’s easy to source chisels for.
If you want a dependable Pneumatic jack hammer that feels stable in the hands and holds up with basic care—regular oiling, clean airflow, no empty strikes—the B67C is a strong pick for contractors who deal with tough surfaces every day.
