Drilling for Profit with SUMO3CHAM

ISCAR unveils new SUMO3CHAM drilling system


The global metalworking industry is driven by the relentless progress of high-end technologies that are becoming every more sophisticated. The challenging requirements of advanced production equipment demands the provision of ‘out of the box’ advanced machining solutions. Innovative cutting tools release the latent productive capability of modern machine tools and deliver enhanced profits to users.

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 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 three 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 three 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 combination of the self-centering geometry, along with a robust and accurate clamping system results in SUMO3CHAM providing ultimate performance relating to hole cylindricity, roundness, and enhanced productivity.

The entire machining process becomes much easier as the cutting forces are spread across three cutting edges, the drilling process is more stable, and the penetration into the part’s material is more balanced. Thus, users can work up to twice as fast, as the feed per tooth can be increased significantly. Alternatively, users can maintain the same feed per revolution as with a two flute drill, and achieve much longer tool life.”

The SUMO3CHAM clamping, which relies on three points of positioning, provides high levels of repeatability when replacing the drilling head. Three radial and three 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.

The unique geometry of SUMO3CHAM self-centering head shapes the produced chips optimally to allow smooth evacuation throughout the three high helix polished flutes.

ISCAR maintains its proud tradition of designing user-friendly drilling systems for easy handling. These unique systems eliminate the use of tightening screws to clamp the drilling head in accordance with the company motto: “No Set-Up Time”.

SUMO3CHAM is now available for machining alloy steel, carbon steel, and soft and gummy low carbon steel, as well as cast iron.

ISCAR’s vision is to remain the global metalworking market leader by continuing work of its prolific R&D department, and remaining aware of its customers’ evolving needs. Innovative developments allow the launch of products that bring manufacturers an array of efficient drilling solutions based on uncompromising quality.
