Applications
This drill insert performs exceptionally well when machining components made of aluminum, non-ferrous metals, and various plastics. It is primarily used on modern indexable drills and is geared towards professional metalworking in both single-part and series production. The sharp cutting edge geometry makes it highly suitable for preventing material adhesion during aluminum machining.
Special features
The uncoated RT100 carbide substrate (K10-K15) features high wear resistance combined with a specialized design for non-abrasive materials. The available configurations, ranging from SPGT 050204 to 140512, allow for precise adaptation to different drill diameters. Reliable chip evacuation and high dimensional accuracy are central characteristics of this cutting tool.
