APT Pneumatic Chipping Hammers — 2, 3 & 4 in. Stroke
Seven American Pneumatic Tools air chipping hammers in stock in Denver, from the 12-lb M652 to the 22-lb heavy-duty M44: scaling, chiseling, form stripping, cement finishing, light demolition, and mixer clean-out. Every model comes in .680 round or .580 hex nose with your choice of three retainer styles.
The short version
Match stroke to the work: 2-in. for fast, light chipping and finishing (M652), 3-in. for the everyday balance of speed and punch (M653, M263, M43), 4-in. for harder hits on tougher concrete (M654, M264, M44). Then pick your series by duty: 650 series is the classic light pistol grip, the 2-bolt 260 series adds APT’s patented automatic ball valve, and the 4-bolt M43/M44 are the heavy-duty shop-and-shipyard hammers.

650 Series — The Light Classics (12–16 lb)
APT 652 Pneumatic Chipping Hammer

APT 654 Pneumatic Chipping Hammer
The hardest-hitting 650: a 4-in. stroke slows the rate to 1,375 BPM and puts more energy in every blow for tougher concrete and heavier scaling.

14 lb · 14-9/16 in. · 3-in. stroke · 1,650 BPM · 33–35 CFM
APT 264 Pneumatic Chipping Hammer
The 260 with the harder blow: a 4-in. stroke and inside trigger for detailed work that still needs real hitting power — scaling, chiseling, and mixer build-up removal.
15 lb · 15-9/16 in. · 4-in. stroke · 1,375 BPM · 34–36 CFM
M43 & M44 — 4-Bolt Heavy Duty (21–22 lb)

21 lb · 16-3/4 in. · 3-in. stroke · 1,650 BPM · 33–35 CFM
APT M44 Pneumatic Chipping Hammer
The M43’s harder-hitting twin: same 4-bolt heavy-duty build with a 4-in. stroke for the strongest blow in the APT chipping line.

Chipping Hammer Questions, Answered
What is a pneumatic chipping hammer?
A pneumatic chipping hammer is a hand-held air hammer that drives a chisel, moil point, or scaling tool for surface work: removing weld slag and scale, chipping concrete, stripping forms, cement finishing, and cleaning build-up out of mixers. Lighter and faster than a breaker, it is the precision percussion tool of the air-tool family. APT builds seven, from 12 to 22 lb.
Which stroke length should I choose?
Stroke sets the blow: 2-in. (M652) hits fastest and lightest for finishing and thin scale; 3-in. (M653, M263, M43) is the everyday balance; 4-in. (M654, M264, M44) hits hardest at 1,375 BPM for tougher concrete. Most first-hammer buyers do best with a 3-in. model.
What is the difference between the 650, 260, and M43/M44 series?
Duty class. The 650 series is the classic light pistol-grip hammer (12–16 lb) with a flapper valve. The 260 series (14–15 lb) adds APT’s patented automatic ball valve and a 2-bolt drop-forged handle. The M43 and M44 (21–22 lb) are the heavy-duty pair: 4-bolt handles with grade 8 bolts for easy service, and extra mass that does the pushing for you on all-day work.
.680 round or .580 hex nose — which do I need?
Match the nose bushing to your steel: .680 round collar shank steel is the most common in the US; .580 hex locks rotation for tools like scaling chisels. If you already own steels, buy the nose that fits them — both cost the same.
What do the retainer options mean?
The retainer holds the steel in the nose. Standard oval collar with spring ($678) is the classic; the quick-change ball retainer with locking spring ($769) speeds steel changes; the bolt-on ball retainer ($791) needs no spring at all. The -02/-04/-06 suffixes on APT part numbers are exactly these three options.
What air compressor does a chipping hammer need?
All seven APT models run on 32–36 CFM at 90 psi with a 7/8-24 inlet — a small towable compressor or a healthy shop compressor handles one easily. See the compressors we stock.
Are these the same tools as APT 18668-04 or 5298-02?
Yes — the base number is the model (5298/5299 = M652, 5300/5301 = M653, 5302/5303 = M654, 18667/18670 = M263, 18668/18671 = M264, 18850/18851 = M43, 18852/18853 = M44; the pair covers round vs hex nose) and the suffix is the retainer. Order by either numbering.
How fast do APT chipping hammers ship?
Every configuration on this page ships same day on orders by 4 PM Eastern, free UPS Ground on most orders, from Denver.
