USAGE: Hard Plastic, Solid Surface & Aluminum

This solid carbide tool is a great all-purpose cutter. It will give a good finish in a variety of materials. These tools are designed to have a longer life when compared with high speed steel (HSS). Solid carbide has a harder edge that holds up well against friction, however these tools are more brittle and may break if dropped or abused. For longer tool life try the TiN coating (pictured right).
