Polledri Back Spotfacing System Group 20
QUANTITY
With a range from diameter 12 to diameter 125, backspotfacing cutters are manufactured to be fixed to the wide range of pilot arbors diameters through a quick change bayonet which allows, in a short time to fix and remove the citter from the arbor in a way that it’s possible to change quickly from one hole to another one.

The arbors specially devised for our back-spotfacing cutters, have a threaded hole at the end of the taper to allow the locking of the arbor to the machine by means of a drawbar. Alternatively, they can be used with the tang end and locked to the machine with the positioning slot if available. M.T 3 (up to Ø 24) and M.T. 4 (from Ø 25) with locking slot DIN 1806
