Parting blade for turning purposes
First Claim
1. A parting blade, comprising:
- a flat, elongate body, including two opposite side surfaces, two opposite ends and two opposite, longitudinal edges which are mutually parallel and present chamfered surfaces for wedging the body in a holder;
an insert seat formed adjacent to one of the two opposite ends, the position of which seat in relation to a longitudinal edge determines the tip height of a turning insert mounted in the insert seat, the parting blade including an attachment part projecting from one side of the blade body, which attachment part is shorter and thinner than the body, said attachment part including two opposite longitudinal edges, which are mutually parallel and present chamfered surfaces for wedging the attachment part in another holder;
wherein a flat waist piece is formed between the attachment part and the blade body, which waist piece is thinner than the attachment part.

Abstract
A parting blade having a flat, elongate body, which is delimited by two opposite side surfaces and has two opposite longitudinal edges which are mutually parallel and present chamfered surfaces for wedging the body in a holder, and which includes at least one insert seat formed adjacent to an end, the position of which seat in relation to a longitudinal edge determines the tip height of a turning insert mounted in the insert seat. An attachment part is formed on one of the side surfaces of the blade body. The attachment part is shorter and thinner than the proper blade body and has two opposite longitudinal edges which are mutually parallel and present chamfered surfaces for wedging the attachment part in another holder. In this way, the parting blade can be formed for robust, wide turning inserts and in spite of this be mounted in holders intended for considerably thinner parting blades.
