elm flm breaker insertsClick image to enlargeImprove surface finish in long-chipping materials with Big Kaiser Precision Tooling’s two new insert chip-breakers.

Long chips that are difficult to evacuate can be dragged across the workpiece, leading to poor surface finishes. Insert life can also be severely reduced if these chips are re-cut by the insert, and in small-diameter applications stringy chips can wrap around the tool to the point where a crash occurs.

Use the FLM 3D chip-breaker design on PCD-tipped inserts for finishing aluminum components, where traditional flat-top inserts may produce a large continuous nest of chips that is difficult to remove from the bore or tool. Three different radius options are available: .008”, .016” and .031” for the insert TCGT2 (1.5).

For finishing in mild or construction steels, cermet inserts with chip-breaker form ELM should be used. Available in .008” radius and combined with a light depth of cut, this chip-breaker creates a high-shear angle to shorten the cutting chips for better evacuation and superior surface finishes in these traditionally difficult materials.
