Buy direct from THINBIT. LITTLEBIT 3 Pack LGI075HSFR 'L' Series, Uncoated high speed steel, Grooving insert. .075 wide, Full Radius, .038 radius. .112 depth of cut. High speed steel will cut most materials. It will take considerable abuse. However, high speed steel will not wear as well as carbide. We suggest the use of high speed steel for jobs of 500 cuts or less. It also works well on older machines which do not have high enough spindle speeds to take advantage of carbide.
