Sharpens the inside of square chisels with a six flute HSS cutter. After sharpening the inside, you deburr the four outside faces using the flat diamond stone supplied.
Chisels should be held gently in a vise, and use the HSS cutter in a cordless drill to sharpen the inside of the mortise chisel. Control the power of the drill to ensure a minimal amount of material is removed, therefore extending the life of the chisel.
The kit includes four guide pins of common internal diameters to align the HSS cutter with the inside of the square chisel. There is simply no other way to successfully sharpen mortise chisels.
An essential accessory for anyone who uses a chisel mortiser.
Sharpens mortise bits 1/4", 5/16", 3/8" and 1/2".
