Standard keyway broaches duMONT |
|
Keyway broaches made of HSS in keyway tolerances JS9, P9, H9 according to DIN 6885, inclusive shims, for use in materials up to hardness RC30/BR285. The standard duMONT keyway broaches are manufactured with an universal face angle of 8° to 10°, that's why different materials as cast iron, steel, brass and aluminium can be broached perfectly. For materials difficult to cut you have to use specially grounded broaches. |
