Grinding On Centre really Matters

We grind with a truely centred jig

Sharpening using the industry standard Tormek T8 and its dedicated twist drill jig we can put almost any angle of grind on a dill from 3 to 22mm. The flanks are equal, the clearance correct and the point angle can be set for hard or soft materials to suit your needs. 
We grind the edge underwater with this system ensures the edge is kept cold and clean and no loss of temper and hardness. . 

Accuracy & The Benefits

The jig is quite complex with interleaving V blocks bringing the drill to a perfect centre line. Setting the cutting edge to the indicators makes for an on centre grind and with a four flank grind the drill has a true point. The result: no wandering in the drill press and no oval or off centre holes.
