TNT Cutter blades are made from high-quality, heat-treated tool steel. They have a wear-resistant anodized surface. Variable speed and deaman control increases manageability in critical situations. The Cutters are well-balanced for easy positioning. A D-shaped wrap-around handle ensures easy operations in all positions for left or right-handed operations. The confined space cutter has an internal safety bleed valve to prevent over pressurization. Regrindable blades extend the blade life. It also has an anodized aluminum body and separate controller.
