FLAT SLOTTER(CARBIDE)
FLAT SLOTTER(CARBIDE)
Material: Solid carbide material, the hardness reaches HRA92.5 or above, quite high hardness. The cutting edge is sharp and no longer need to change the cutter when cut the iron key.The service life
Production process: CNC precision grinding process, full edge grinding teeth, shock protection of the edge tip; Strict size control, tolerance of thickness within 0.01mm, taper design of flat belt, can cut 20mm depth of slot of Mortice keys.
is more than 3 times longer than ordinary white steel.
In view of the characteristics of carbide brittleness, RAISE invented a unique grinding process, strengthen the design of the cutting edge and improve the rigidity of the tip of cutter. It`s very good to overcome the problem of broken teeth.
