IC808 Grade Description:
(P15-P30/M20-M30/K20-K40/ S15-S25/N15-N25/H20-H30) SUMO TEC TiAlN PVD coated. A tough submicron substrate. For machining heat resistant alloys, austenitic stainless steel, hard alloys and carbon steel at medium to high cutting speeds. Excellent notch wear and built-up edge resistance.

TAG N-J/JS/JT 
Parting and grooving inserts
Single-ended insert For Parting - With a vastly improved clamping method.

Features and Benefits 
• Incredibly rigid clamping in a tangentially oriented pocket
• Allows machining at very high feed rates and provides excellent straightness and surface finish
• Recommended for parting large diameter parts - great for interrupted cuts
• Offers a free, unobstructed chip flow - since there is no upper jaw like in other clamping systems (very important in deep grooving and parting applications)
• The combination of tangential clamping and free chip flow results in improved tool and insert life time
• Provides a solution to the problem of inserts being pulled out during retraction

The TAG inserts are available with the familiar J- and C-Type chipformers, with neutral and angular frontal cutting edges. The new tools are equipped with a user-friendly clamping and extraction device. The TANG-GRIP family includes square shank tools, blades and inserts in 1.4 - 9.5mm widths in the most advanced IC830 and IC808 SUMO TEC grades. The blades are in standard siuzes which fit ISCAR's standard blocks.

Parting Blades

ISCAR Tang-Grip? has the following features:

? Enables machining at high feed rates and provides excellent straightness and surface finish.
? Provides a solution to the problem of inserts being pulled out during retraction. Has a solid stopper, unlike the friction retaining force in the current systems. (Especially important on machines with a bar feeder or sub spindles.)
? In the SELF-GRIP? system the machining forces are exerted on a very short stopper, while in the TANG-GRIP system, machining forces are supported by a long and rigid rear wall. Pocket wear, which occurs during machining and insert indexing in the SELF-GRIP? system, causes a reduction in the clamping force. This does not happen with the new TANG-GRIP? system.
? The TANG-GRIP? system provides very accurate grooving repeatability.
? The combination of tangential clamping and free chip flow results in improved tool and pocket life. 
? Offers a free, unobstructed chip flow. This is very important in deep grooving, since there is no upper jaw to interfere as in the other clamping systems.
 
For all technical specifications and inserts please refer to our catalogue.
