Dormer's indexable inserts are manufactured in cobalt alloyed High Speed Steel and are available either in bright finish, with TiN coating or with TiAlN coating.

The sides of the inserts are hollow ground, which means that the clearance will be correct radially as well as axially. TiAlN is harder than TiN and can withstand higher temperatures.

A chipbreaker has been shaped in the cutting surface of the edge in order to obtain the best possible type of chips when working in long-chipping materials.

Dimensions: Indexable inserts are available in two sizes with straight edges and with 8º and 15º lead angle in both left hand and a right hand version. Tools for standard retaining ring size grooves, with widths of 1.1, 1.3, 1.6, 1.85 and 2.15 mm, are also available
