ISCAR’S New SUMOCHAM Drills
ISCAR’s new SUMOCHAM drill family is an advanced evolution of the very successful CHAMDRILL and CHAMDRILLJET drill families.
The drill features twisted coolant nozzles with indexable drilling heads which are available in different head configurations for various material groups. SUMOCHAM drills can be used either on milling centers or lathe machines.
Drilling Heads
SUMOCHAM features four different standard drill head geometries, designed for optimal performance and high reliability when used on various materials.
The drill head is manufactured with a sharp cutting edge and polished flutes.
SUMOCHAM drilling heads are available in the diameter range of 8 to 25.9 mm.
The drill head has ground flutes for smooth, uninterrupted chip flow and a ground gash for improved penetration and productivity can be increased by up to 100%.
Drill Body
The drill shank design is according to DIN 9766 standard, with available drilling depth to diameter ratios of 1.5XD, 3xD, 5XD and 8xD. All drill bodies feature helical coolant holes.
The accurate cylinder added to the clamping portion improves rigidity and reduces internal stresses. The rotation stopper planes on the tool are precision ground, which improves the control on the drilling head position and support, ensuring better tool performance and tool life.
SUMOCHAM drilling head pocket features 33% less internal stress and thus significantly increases the drilling head replacements.
To prevent the insert from being pulled out during drilling, there is an axial stopper in the pocket, which is effective even after the clamping force has been lost.
ISCAR’s innovative SUMOCHAM drill line will provide longer tool life and higher productivity.
