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

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 range of material groups. SUMOCHAM drills can be used on milling centers or lathes.

SUMOCHAM incorporates four different standard drill head geometries, designed for unsurpassed performance and high reliability. The drill head is made 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 enhanced penetration.

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 coolant through holes. The accurate cylinder added to the clamping portion improves durability and reduces internal stresses. The rotation stopper planes are precision ground, which improve the control on the drilling head position and support, increasing tool performance and life. ISCAR's innovative SUMOCHAM drill line will provide longer tool life and increased productivity.

DR-DH Deep Drills

DR-DH drills can obtain drilling depth-to-diameter ratio of 7XD and up. Engineered to be implemented on standard horizontal milling centers, turning, and multi-task machines. Use of supplemental machine and setup can be avoided. They will be obtainable 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 that has a patented chip gullet design. It was designed for easily cut materials like cast iron and low alloyed steel.

A Double Flute DR-DH-31.65-0350NC-2FD has a double chip gullet for better chip flow. It was tailored for drilling gummy materials like 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 reach bottom10% faster than with other solid carbide drills - and six times faster than a HSS drill. This ability can speed up countless high-volume operations. The deep-hole drilling station no longer has to slow down a transfer line or stop it exclusively because a drill breaks.

Different target applications encompass 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 expel chips more surely. A unique high-strength core creates a more durable drill point and allows for deeper flutes, enlarging the departure path for chips.

The drill tip themselves have a 140 positive-point, four-margin design to maintain the edge, diminish thrust forces and help centering and tracking. A post-coat polishing measure on the flutes, margins and cutting edges decreases 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 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.
