Bosch PRO Masonry Flat Chisel 1600A03A9W, 250 mm

Bosch PRO Masonry Flat Chisel 1600A03A9W, 250 mm

The Bosch PRO 1600A03A9W is a flat masonry chisel with a 250 mm shank, a 22 mm wide blade and a 16 mm shank diameter. The body is chrome-vanadium steel with a hardness of HRC 54-58, and a hand guard with a two-component grip is fitted around the shank.

Hand protection

The rubber flare around the shank is what separates this chisel from a bare one. When the hammer blow misses, the guard absorbs the force instead of it reaching the fingers holding the tool. The grip is two-component and does not slip, and its cone also forms a surface that steers the blow and keeps the hand clear of the chiselling zone.

Tip and steel

The tip is flat and 22 mm wide, made from induction-hardened steel - a treatment that hardens the zone at the edge itself while the shank stays tougher and absorbs the blow without cracking. A hardness of HRC 54-58 is the compromise at which the edge holds its shape in masonry but does not chip on hard stone or reinforcement. The chrome-vanadium shank is 16 mm in diameter - enough section not to bend under side loading.

Applications

Hand chiselling and trimming of masonry: opening chases for services, cleaning out joints and old mortar, dressing brick and block, removing render and tiles, breaking out small areas where a breaker would be excessive. The tool is struck with an ordinary club hammer.
