ISCAR TECH TALK SUMOCHAM

ISCAR has introduced the SUMOCHAM drill family, the next evolution of the very successful CHAMDRILL family. The SUMOCHAM drills have features similar to the CHAMDRILL and CHAMDRILLJET, with improved head and pocket design, together with no setup time, fast metal removal and economy indexing. The SUMOCHAM comprises a revolutionary clamping system that enables improved productivity output rates, while enabling more insert indexes. The shank itself is designed with twisted nozzles and exhibits a durable and stably constructed body. The indexable heads are available in four different standard geometries. Each one of them is designed for drilling steel, exotic materials, cast iron or aluminum. The unique pocket design of the SUMOCHAM takes good advantage of the cutting forces, which are mechanically exerted upon the tool. These forces are then converted into gripping forces that are used for tightening the insert towards the back of the pocket. In that sense, the more cutting forces applied, the better gripping forces obtained. The clamping forces around the connection area generate little strain, preventing any potential plastic deformation and by that providing at least triple the amount of head indexes. The most important attribute of the new clamping design is therefore a 50% increase in productivity. The drill head is also designed with a dovetail connection, eliminating any possibility of insert pull-out, while utilizing an enlarged clamping area and stopper at the back.
