Tungaloy Enhances BTA Drill Inserts for Deep Drilling of Superalloys and Stainless Steel

Iwaki, April 2020 — Tungaloy is expanding the insert line of FineBeam BTA drill series to include AH8015 grade inserts with the G style chip former.

FineBeam incorporates high quality inserts and guide pads to enable high precision deep hole drilling. AH8015 consists of a nano-multilayered PVD coating with high aluminum content. This coating characteristic provides increased resistance against wear and built-up edge over existing grades, enabling long and predictable tool life during the machining of heat resistant superalloys and stainless steel. Combined with the versatile G style chip former, the new inserts enable high quality holes and prolonged tool life in every deep hole drilling application.
