In order to comply with market demand, ISCAR recently exhibited its next generation, advanced indexable drill and further extended its comprehensive product portfolio with the launch of SUMO3CHAM – an advanced three flute indexable drill.

 

The innovative design of the SUMO3CHAM raises users manufacturing productivity to new levels by reducing machining cycle times by up to 50% when compared to the conventional two flute drills.

The new product’s pocket configuration is constructed on a ‘close structure’ design with three contact areas based on a dove tail joint. This rigid clamping configuration divides the forces applied to the tools’ pocket into 3 segments. This arrangement dramatically reduces harmful influences on the pocket’s life and also substantially prolongs tool life. In a similar way, the cutting forces are equally divided across the 3 cutting edges of the drilling head. The application of less pressure to each of the contact surfaces further extends the life cycle of the drilling head.

The SUMO3CHAM clamping, which relies on 3 points of positioning, provides high levels of repeatability when replacing the drilling head. Three radial and 3 axial stoppers secure the drilling head and ensure a reliable drilling process in high feed machining environments. Furthermore, due to its sharp edges and the low axial force it applies, the SUMO3CHAM is very efficient when drilling a through-hole when the drill breaks through a slanted surface, also creating fewer burrs on the hole exit. Since the material work hardening is low, a reamer or a tap which may be used for a subsequent operation will gain from extended tool life and accomplish improved results.
