Stanley 4-18-287 Flat Tip Cold Chisel 12 x 150 mm (1/2 x 6 in)

The Stanley 4-18-287 is a 1/2 x 6 in flat-tip cold chisel: a 12 mm chrome vanadium steel blade with a 150 mm blade length. Stanley states it cuts and smooths iron, cast iron, steel, brass, bronze, copper and aluminium, and cuts nuts and rivets. The chisel is forged in one piece for strength, then hardened, quenched and tempered for long life and durability. Its octagonal shape stops it rolling away, and the treated, powder-coated finish adds visibility and protection.
