This is a hosted groupbuy of Grewin endmills for the FRC community. 

Grewin endmills are high quality endmills that perform extremely well in testing, producing a good surface finish and supporting feed rates above 2 cubic IPM. Since their first introduction, several teams have successfully run these for many seasons without issue. However, due to the large minimum order quantity and relative hassle of dealing with international payments and shipping, they can be quite inconvenient to purchase from.

To help solve this, Redux is hosting a groupbuy of endmills from Grewin, utilizing our warehousing and logistics chain to help deliver these to teams. 

All endmills come in a 5-pack.
