Sharpening Stems

Insert life can be extended through re-sharpening of inserts that show a decline in the surface finish (a sign of wear). Sharpening stems, available in 5 sizes, are designed to accept specific insert sizes. The insert is removed from the tool holder and mounted on the sharpening stem. The sharpening stem holds the insert securely in place as the cutting edge of the insert is sharpened at its original angle using a suitable grinder and grinding wheel.
