Clear chips and dust from the pocket.2. Place the insert in the pocket. The insert can be placed only in one direction. I 3. Tighten the screw while pressing the insert into the pocket. How to check the run-out J 1. Clamp the insert on the shank. 2. Clamp the shank on a high-precision arbor. 3. Measure the run-out on tool presetter or by dial gauge.Notes: K 1. Due to the helical cutting edge, it is important that the run-out is inspected with the insert clamped on the shank. 2. Do not use micrometer or caliper to inspect the insert diameter as inaccuratedimensions may be provided. L M Tungaloy H209
