Ripping chisel for air hammers

The Westward 4MHE1 is a scaling chisel built for air-hammer use. Its 0.401 in round shank fits tools that accept the IR collar style. The 6 in overall length and 3/4 in tip width suit edging and material-removal tasks. It is made from 42CRMO steel and ships new.

Shank size and collar constrain fit

The 0.401 in round shank and IR-style round collar limit compatibility to air hammers designed for that exact interface. The chisel is not non-sparking, so it cannot be used in environments that require spark-resistant tools. California Proposition 65 warnings apply for cancer and reproductive-harm chemicals.

Simple insertion but verify tool match

Installation consists of inserting the shank into the air hammer’s chuck and securing the collar. The main issue is mismatching the shank diameter or collar style, which prevents the chisel from seating or retaining correctly. No special tools are needed beyond the compatible air hammer.

Questions about this item

Is the 0.401 in shank the only size offered for this ripping chisel?

The chisel has a 0.401 in round shank and is 6 in long. No other shank diameters or lengths are listed for this model.

What does the 6 in overall length mean when the chisel is fitted to an air hammer?

The 6 in measurement is the total length of the chisel body. It determines reach into the work area when installed in a compatible air hammer.

How does the round collar design affect fitment with the ACL-019 air hammer?

The round collar matches the ACL-019 chuck, allowing the chisel to seat securely and rotate freely during scaling and edging work.
