How innovative tooling enhances cost-effectiveness

One of ISCAR’s most innovative and successful products, the SUMOCHAM line of drills with exchangeable carbide cutting heads is known for being a significant development in the field of holemaking and drilling technology. Part of ISCAR’s modular drilling system, these drill heads are designed to enhance productivity, precision and cost-efficiency.

The SUMOCHAM drill heads are known for the tool’s unique clamping mechanism, which allows for quick and easy replacement of the drill head without removing the entire tool from the machine. This feature significantly reduces downtime and increases productivity. The clamping system ensures a secure and precise fit, which is crucial for maintaining the accuracy of the drilling process.

These drill heads are available in various sizes from 0.157″ to 1.295″ with 0.004″ increments and various geometries to accommodate different materials and applications. The heads are designed with advanced coatings and materials that enhance their durability and performance. For instance, the use of carbide and other high-performance materials ensure that the drill heads can withstand high temperatures and pressures, making them suitable for demanding applications.

One of the standout features of the SUMOCHAM drill heads is the tool’s versatility. SUMOCHAM drill heads can be used in a wide range of materials, including steel, stainless steel, cast iron and non-ferrous metals.

The drill heads are designed to be used with ISCAR’s modular drill bodies, which come in different lengths and diameters. This modularity allows users to customize their drilling setup to meet specific requirements. For example, the drill bodies are available in 11/2xD, 3xD, 5xD, 8xD, 10xD and 12xD length-to-diameter ratios, providing flexibility in terms of drilling depth and stability.

The performance of the SUMOCHAM drill heads is enhanced by the tool’s optimized geometry and cutting-edge design. These features reduce cutting forces and improve chip evacuation, which in turn enhances the overall efficiency of the drilling process. The internal coolant channels in the drill heads further improve performance by reducing heat buildup and extending tool life. In addition, the ability to replace only the drill head, rather than the entire tool, reduces tooling costs and minimizes waste. This aspect is particularly beneficial in high-volume production environments where tool wear is a significant concern.

The new SUMO L DRILL family of drills with exchangeable carbide heads are designed to machine under challenging conditions, such as entering or exiting a slanted surface or drilling through cross holes. Each drill in this family features a robust head securing mechanism that incorporates the SUMOCHAM selfclamping principle and a side lock screw.
