Grinding Jig

This new tool from Alisam Engineering is a reproduction* of South Bend Lathe Works cutter bit grinding block not in production for many years! Each grinding block will come with your choice of 2 square tool bit holders, (any of the other size tool holder/s are available separately as well). Tool holders come in 5 different sizes, 3/16, 1/4, 5/16, 3/8 and 1/2 inch to fit most quality, ground, square modern tool bits! (*We have increased the capacity of the tool holders by adding the 1/2 inch square tool bit size which was not available from SBL, in doing so increased the overall size of the block and the diameter of the toolholders by about .19 inch. Thus our model will NOT interchange with the original*). 

Please specify which two sizes of the tool holders you would like upon check out!
