The Crescent 4" x 7" Brick Chisel, part CBCH40. Supplier specification: CHISEL 4"X7-1/2" BRICK.
Match the chisel to the material. A wood chisel has a fine bevel for timber and will chip on anything harder; a cold chisel has a blunt, tough edge for metal and masonry. They are not interchangeable, and using the wrong one destroys the tool on the first strike.
