What can you do with Poliangolar



Is it possible to broach stainless steel material?

Yes, in addition to standard production in HSS, we can supply sintered + coated tools suitable for broaching very hard materials (max. 28/30 HRC).

What is the correct pre-hole measurement to be made before machining?

For hexagons, pre-drilling 5% more than the inscribed diameter is recommended. Example: Hexagon 10 - pre-drill 10,5.
For squares, 10% more is recommended.

Should the tool be resharpened?

Certainly yes. As the cutting edge wears down (rounding off), the machining effort increases considerably, making it easier to break the tool.
