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

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 enables high quality holes and prolonged tool life in every deep hole drilling application.
