The grinding jig has all the angles for correct tip geometry built in. It accurately positions each type of bit over the wheels to give the correct tip and relief angles.
Extends drill bit life for years. The high quality aluminium oxide and silicon carbide wheels sharpen at least 150 HSS/wood bits and 75 masonry/SDS-Plus bits based on 6.5mm (¼”) dia. size.
Also re-edges and re-points a whole range of small tools,including carbide-tipped. Makes them easier to use, and extends tool life. Also useful as mini bench grinder.
