These smaller, cast iron cutting heads are one of the most commonly ordered accessories for the Morso NM Machines.
Made for easy interchange with the standard cutting head, these "smaller" heads differ from the standard heads only in the fact that the two sides actually come to a point at the tip, while the larger heads have an approx. 1/4" flat area at the tip. The standard "L" heads will accept nose knives from 1/2" - 1", while the smaller "S" heads accept knives from 1/4" - 3/8". The small 1/4", 5/16" and 3/8" knives are very useful when joining small mullion and muntin grids with half-lap joints.
Always return dull MORSO knives to Hoffmann Machine Company Inc. for grinding and honing to factory specifications. We have a MORSO grinding machine in our shop here in Valdese, NC to get your knives back to like-new condition.
