Intended Use: Turning Acrylic, Resin and Hybrid Wood/Resin Pieces on a Wood Lathe. AR MSTH: 1/2" solid stainless steel turning tool with 12mm flat top carbide cutter. Produces a shearing cut instead of a scraping cut, ideal for man made materials. AR MS90: 3/8" square solid stainless steel turning tool with 11mm carbide cutter with negative rake angle. Remove material quickly, create lines, grooves or detail work, or hold at a 45° angle and make a roughing cut. One of the favorites for resin! AR MSR: 3/8" square solid stainless steel turning tool with 11mm carbide cutter with negative rake angle. Negative rake angle is ideal for making straight lines and flat surfaces. American Made by Harrison Specialties in Ramsey, Minnesota. CNC precision machined tools and handles give you professional tools to last a lifetime. Rotate the cutter heads as needed, and keep on turning. Acrylic, Resin and Hybrid projects have changed the woodturning landscape. Traditional carbide tipped tools did not perform well with these new materials, so we set out to make a solution. The birth of our Acrylic/Resin (AR) tool line came as a result of a lot of trials (and errors), turning all types of man-made and hybrid projects. The goal was to create tools that could be used to turn any of the man-made materials we could find, while giving the turner as much creative artistic ability as possible. A one size fits all approach did not produce the desired results across all the different materials available, including hybrid pieces. A nod back to a few early woodturning techniques with the development of carbide tools used like traditional gouges also proved to be a very successful and great approach. Handle Details: Material: Solid aluminum CNC machined with comfortable foam grip handle Overall length: 17" Outside diameter: 1 3/8" Opening for tool: ½" diameter Tools are easily changed by loosening two stainless steel Allen set screws. A few things to keep in mind: Turning acrylics takes longer than wood. Shearing cuts proved to be very successful, where scraping cuts were not. Introduce your cutting edge slowly, try not to “stab” the wood as plastics can shatter with this technique. Increase your lathe speed and slow your tool presentation to the blank. Work from the ends inward. Make light cuts to reduce chip outs. Increase your aggressiveness as you get the feel for it.
