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

SUMOCHAM Drills

ISCAR's new SUMOCHAM drill family is an advanced development of the tremendously successful CHAMDRILL and CHAMDRILLJET drill families. The drill features twisted coolant nozzles with indexable drilling heads which are available in different head configurations for a variety of material groups. SUMOCHAM drills can be used on milling centers or lathes.

SUMOCHAM includes four different standard drill head geometries, designed for unmatchable performance and high dependability. The drill head is made with a sharp cutting edge and polished flutes. SUMOCHAM drilling heads are obtainable 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.

The drill shank design is in accordance to DIN 9766 standard, with obtainable 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 improves durability and decreases internal stresses. The rotation stopper planes are precision ground, to improve the control on the drilling head position and support, increasing tool performance and life. ISCAR's innovative SUMOCHAM drill line will furnish longer tool life and greater productivity.

DR-DH Deep Drills

DR-DH drills can achieve drilling depth-to-diameter ratio of 7XD and up. Engineered to be used on standard horizontal milling centers, turning, and multi-task machines. Use of supplementary machine and setup can be avoided. They will be offered 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 rigid tool that has a patented chip gullet design. It was tailored for easily cut materials such as cast iron and low alloyed steel.

A Double Flute DR-DH-31.65-0350NC-2FD has a double chip gullet for upgraded 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 brand new solid carbide deep hole drills, you can easily drill up to 22 times diameter and attain bottom10% faster than with other solid carbide drills - and six times faster than a HSS drill. This capability can speed up a great number of high-volume operations. The deep-hole drilling station no longer needs to slow down a transfer line or stop it completely because a drill breaks.

Other target applications include deep holes for automotive, hydraulic blocks and die & mold work. A aggregate of features aid the twist drills to cut faster, straighter,deeper, last longer and evacuate chips more surely. A special high-strength core creates a more durable drill point and allows for deeper flutes, enlarging the departure path for chips.

The drill tip itself has a 140 positive-point, four-margin design to maintain the edge, diminish thrust forces and aide centering and tracking. A post-coat polishing measure on the flutes, margins and cutting edges reduces friction and torque that can easily snap a drill.

The latest drills are available in normal diameters ranging from 5 to 10 mm, in 20 and 22 length to diameter ratios. Special sizes are offered on request. All are made 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.
