Iscar recently released a variety of different drilling innovations to meet their customers needs. These latest products are Sumocham Drill, DR-DH and Deep Drills. Drawing off of their experience Iscar has come up with new and innovative ways to expand productivity for the end user. Here is a little bit about these new products, and how they will serve the end user of these products.

SUMOCHAM Drills

ISCAR's new SUMOCHAM drill family is an advanced development of the tremendously thriving 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 on milling centers or lathes.

SUMOCHAM includes four different standard drill head geometries, designed for unsurpassed performance and high dependability. The drill head is manufactured with a sharp cutting edge and polished flutes. SUMOCHAM drilling heads are offered in the diameter range of 8 to 25.9 mm. The drill head has ground flutes for smooth, continuous chip flow and a ground gash for improved penetration.

The drill shank design is in accordance to DIN 9766 standard, with available drilling depth to diameter ratios of 1.5XD, 3xD, 5XD and 8xD. All drill bodies showcase coolant through holes. The accurate cylinder added to the clamping portion increases rigidity and reduces internal stresses. The rotation stopper planes are accurately ground, to increase the control on the drilling head position and support, increasing tool performance and life. ISCAR's innovative SUMOCHAM drill line will allow for longer tool life and greater productivity.

DR-DH Deep Drills

DR-DH drills can acquire drilling depth-to-diameter ratio of 7XD and up. Engineered to be employed on standard horizontal milling centers, turning, and multi-task machines. Use of additional machine and setup can be avoided. They will be available as semi-standard product in a diameter range of 25.4 to 69.5 mm (1.00 - 2.73").

Two versions will be available:
A Single Flute DR-DH-31.65-0350NC-2FS is a very stiff tool having a patented chip gullet design. It was tailored for easily cut materials comparable to cast iron and low alloyed steel.

A Double Flute DR-DH-31.65-0350NC-2FD has a double chip gullet for improved chip flow. It was designed for drilling gummy materials such as non-alloyed steel and high temperature alloys.

ISCAR DEEP HOLE DRILLS

With ISCAR's innovative solid carbide deep hole drills, you can safely drill up to 22 times diameter and reach bottom10% faster than with other solid carbide drills - and six times faster than a HSS drill. This capability can speed up several high-volume operations. The deep-hole drilling station no longer has to slow down a transfer line or stop it fully because a drill breaks.

Different target applications include deep holes for automotive, hydraulic blocks and die & mold work. A combination of features help the twist drills to cut faster, straighter,deeper, last longer and expel chips more readily. A unique high-strength core creates a more enduring drill point and allows for deeper flutes, enlarging the departure path for chips.

The drill tip themselves has a 140 positive-point, four-margin design to maintain the edge, reduce thrust forces and help centering and tracking. A post-coat polishing method on the flutes, margins and cutting edges reduces friction and torque that can readily snap a drill.

The new drills are found in standard diameters ranging from 5 to 10 mm, in 20 and 22 length to diameter ratios. Special sizes are obtainable on request. All are manufactured of IC908, a 10% cobalt submicron carbide grade, and comes with a TiAlN PVD coating, and can be refurbished.

These are just some of the latest innovations coming from Iscar.
