The chipping hammer blank is unshaped tool steel with a finished shank: grind or machine the business end into whatever profile the job calls for a gouge, scraper, custom chisel or one-off carving edge. Supplied in 8 in. and 11 in. lengths with .580 hex or .680 round shanks and oval or round collars, it is the starting point for edges no catalog steel covers.

Shops keep blanks on hand for restoration work, stone carving profiles and specialized scraping or deburring edges; the shank end is already sized to run in any matching pneumatic chipping hammer. Before grinding a custom edge, check whether the pre-shaped chipping hammer chisels points, flats, spades and drivers already cover it, and see the chipping hammer buyer’s guide for how shank and collar options pair with retainer types.

Chipping Hammer Blank FAQ

What shank and collar options are available?
Blanks come in 8 in. and 11 in. lengths with a .580 in. hex or .680 in. round shank and an oval or round collar.

Will a blank run in my chipping hammer?
Yes — the shank end is finished to standard dimensions, so it drops into any chipping hammer with a matching chuck and retainer; only the working end is left unshaped.

Why buy a blank instead of a shaped chisel?
For edges no catalog steel covers — gouges, scrapers, carving and restoration profiles. Check the pre-shaped chisels first; if the profile you need is not there, grind it from a blank.
