The highlight of the 3P product introduction is the Sumo Tec premium tungsten carbide grades that Iscar said meet the challenges of contemporary drilling, milling, turning and grooving applications. Complementing Sumo Tec, Iscar developed a new series of tools and inserts that it is marketing as “Sumo” lines.

Iscar Metals Inc. (www.iscarmetals.com) has developed a new metalworking concept for increased productivity.

For parting, Iscar’s Tang-Grip line has tangential inserts that use the latest Sumo Tec 800 series grades to provide superior flatness and surface finish.

Iscar said it engineered the new grades to significantly extend insert tool life as a result of an innovative substrate. In addition, the Sumo Tec grades feature advanced CVD and PVD coating technology.

The milling line, called Sumomill, has tangentially clamped inserts with high positive cutting angles.

Iscar said the new process improves toughness and chipping resistance, thus reducing friction and built-up edges to prolong tool life at increased machining conditions for all types of workpiece materials.

Iscar called its new concept the 3P Sumo Line for Premium Productivity Products (3P), and said its new line of tooling provides better productivity, better profitability and better tooling performance.

These single-ended inserts perform parting, grooving and interrupted grooving operations and feature rigid clamping and a tangentially oriented pocket for machining at high feeds with extended tool life.

For deep-hole drilling, Iscar offers the Chamgun exchangeable gundrill head that is designed to drill up to 30 times its length-to-diameter ratio. Chamgun enables the replacement of a drilling head on the machine, eliminating the process of removing the drill for indexing.

Completing the line of the indexable drills, the Sumodrill, is for heavy duty, large diameter rough drilling applications from 61 mm to 80 mm.

The PVD process is composed of Iscar’s Al-Tec coating technology. The CVD coating is based on Iscar’s Alpha-Tec technology that is resistant to wear, followed by a process that provides improved tool life, low insert surface stresses and an evenly coated top surface that contributes to smooth uninterrupted chip flow, less generated heat and less friction.

For heavy duty turning, Iscar introduced Sumoturn inserts made from the Sumo Tec 5000 grades for cast iron and Sumo Tec 8000 grades for machining steel and stainless steel. The company expanded its Heliturn LD family by adding inserts with positive radial helical cutting edges and positive rake angles that are designed to reduce cutting forces and facilitate higher productivity.

Iscar also has expanded its Helido double-sided helical positive geometry inserts with the H600 Upfeed line, and its Helitang 490 line for machining steel and steel alloy at high feeds. All of the latest Helido, Helitang and Sumomill lines, including the existing designs, now are available in the latest Sumo Tec PVD IC800 series grades.

The Sumomill T290 family of endmills use a large number of insert cutting edges on a small tool diameter to enable increased feedrates for high productivity.

The Dr-Twist line has twisted coolant holes, large gullets for chip evacuation and the advantages of the Sumo Tec grades.
