Tools 7pc 6mm Carbide Burr Set Burrs Tungsten Steel Hole enlarger 7072 - Us Pro

A seven piece set of double cut tungsten carbide burrs in a range of shapes. Extremely hard wearing and suitable for work with metals, plastic and wood. Our Tungsten Carbide Burr's are made from pure raw material which means they can be hardened to HRA 89-91. The sintering process is performed in a pressure furnace to keep volatilisation to a minimum and ensure the highest hardness is achieved. Manufacturers that use scrap material and a vacuum sintering process cannot reach the same level of hardness. A silver braze is used rather than a copper braze favoured by other manufacturers as it can be applied at a lower temperature that will not affect the concentricity and hardness of the burr and shank.
