This range of single flute RT cutters are used to produce chamfers and are ideal for V grooves on softwood, hardwood, MDF and other manmade materials. The design and the specially ground tip produce a perfect V in the bottom of the groove. Angles are measured from the vertical, i.e. a TTVGC60SFRT-1/2 has an inclusive angle of 120 degrees on the tool. Cutters come complete with one tip already installed, the L308 tips are reversible the others are non reversble. Tips are sold in boxes of 10.
