Cutting blades forged entirely from heavily alloyed steel for a thoroughly hardened blade with a sound structure. The ground edges of the cutting blades are subjected to a second hardening process which ensures maximum hardness of the cutting surface. The cutter head may be adjusted to compensate for blade wear. Suitable for cutting high tensile steel bars, bolts, chain and metal sections. Capacity: mild steel 9mm, high tensile 6.5mm. Length 460mm (18”).
