Note: Keep the cutters sharp. Dull cutter teeth will work harden the tube material and lead to tooth damage or a shattered cutter.
ASP 2004 Powder Metallurgy High Speed Tool Steel is an extremely versatile high speed steel that provides a unique combination of high wear resistance from the large volume of vanadium carbides with high impact toughness and transverse bending strength which are results of the fine grain size, small carbides and superior cleanliness of the powder metallurgy microstructure. ASP 2004 offers improved cutting tool life and provides better toughness and wear resistance than high-carbon, high-chromium steels.
