Packed in heavy-duty vinyl rolls for easy access organization and storage. Manufactured to the highest safety standards cold chisels are individually forged from high quality alloy steel. The alloy content in these makes them ideal for all types of metalworking and masonry applications and also increases wear resistance significantly. The precisely ground cutting edge is induction hardened (52 58 HRC) to give improved performance over longer periods of time. Hardness at the striking end is maintained to under 42 HRC so that the head will not splinter when subject to hammer blows. Shank is powder coated and the cutting edge is accurately ground.
