Polledri Counterboring System Group 0

0

Counter Bore

Polledri Counterboring System Group 0 ( Insert drills, Pilots, Counterbores, Countersinks and Toolholders )

QUANTITY

( From 7 to 24mm )

A wide range of cutters are available for Spotfacing and countersinking in both 90 and 60 degrees- from 7 mm to 85 mm Ø, in 0,5 mm increments. The system also offers a wide range of pilots or drills which when combined together allow drilling and countersinking in one operation. The cutters and pilots can be simply fixed by two screw to different styles of toolholders, which provides a swift method of producing special tools from a range of stock items, which because they are a massed produced make them cost effective, when compared to special tools.

You con fit them in all the Polledri's mandrels of the same group. With fixed or rotating pilots, or drills, you can execute simultaneous operations. We advise them for materials with high hardness, cast iron and steel, if you have an high power machine. You can use high feeds because the two inserts are concentric, for this the chip is distributed equally.

Interchangeable Drills in HSS HRC 63 from Ø 4,2 to Ø 7

Fitting them in the counterbores and countersinks you can drill and counterbore or countersink simultaneous. Using a good soluble oil you can increase the speed, with an increase of the tool life.

IMPORTANT!

On each cutter is possible to mount a guide or a drill, in this second case, the tool can only work through holes and NOT dead holes. The length of the helix of the drill must be such that come out from the hole before the cutter starts to work
