The elmass © broaching tool simplifies slotting. One minute is all it takes to assemble the tool. Install it on your elmass broaching machine, pedestal drill, slotter, lathe or shaper and cut precise internal keyways, hexagons or splines in through holes and blind holes. The cutting depth is steppless adjustable and allows the hassle-free cutting of under and over sized keyways or splines. No shims are required! The tool is self-centring and forces slots to be in a 90 degree angle to the bore. The standard tolerances are H9/JS9 or P9. The single tooth tool offers many advantages. Just by combining the desired shape of cutting tip with the appropriate tool bar and guide bush, the elmass © broaching tool is convertible to cut keyways, straight sided or involute splines and hexagons.
