POLLEDRI,Manufacture of compounding end mills and tools

POLLEDRI SRLPolledri boast a consolidated experience in the manufacture of interchangeable cutters and tools like:
interchangeable system,back spotfacing cutters,and countersinks.
Long duration, high performance, flexibility, are the most significant characteristics of the offer of the Olgiate Olona’s firm in Varese, with a new production program, that point mostly on the performances of materials and adopted geometry.
The large range of cutters and tools of Polledri’s trademark is able to satisfy the most sophisticated request of working. The advantages are considerable in final results and costs reduction, guaranteed at anyone who use it.
The firm has constantly concentrated its efforts to improve the production’s program, investing both in the technological development and in the reliability and quality of the service offered.

For holes whose maximum length is less than three times the diameter (3xØA) and whose counterbore is less than double
the diameter of the hole, we have developed a catalog of special products with Whistle Notch (C) shank, obtained from semi-finished products ready in stock (except sold).
The semi-finished products are made with a special pre-heated material.
This allows you to request a SPECIAL eccentric back spotfacing counterbore, specific for your counterbore, with extremely fast deliveries (about 10 days).
