48 and 50.8 brazed carbide mitre cutters back from Paul Brong Machine. How to cut through heat treated cycle tube including Reynolds 953 with an ultimate tensile strength range 1750-2050 MPa (254,000 psi - 297,500 psi) in approximately eleven seconds without a laser. The hardness of 953 is so close to the hardness of HSS mitre cutters to preclude success. These brazed carbide cutters are resharpenable and if fractured can be repaired - return to Strawberry.
