1. T-GEAR Milling Solid Carbide Heads with T-SLOT Spline Connection
ISCAR is expanding the application options of T-SLOT slot milling cutters with replaceable solid carbide heads by adding new T-GEAR heads that have been designed for gear milling.

The new heads are designated as SD D32-M…-SP15, and have been designed for milling involute gears that meet the requirements of standard DIN 3972, with a basic profile II for finishing and a module range of 1.00 - 2.00 mm.

The new heads feature a nominal diameter of 32 mm with 8 teeth to be mounted on standard T-SLOT SD shanks with SP15 spline connection size.

The new heads enable efficient high-performance involute side milling, increasing the versatility of the T-SLOT tool family.

MODUGEAR Tool for Gear Milling Applications
Iscar introduces another solution for gear milling applications, providing a tool with tangentially clamped indexable inserts.

The new ETS D63-M1-1.75-W25-C disk type tool features a Weldon shank and coolant channels directed to each of the cutting edges. It carries 10 tangentially clamped inserts that can be used for a 1.00 to 1.75 mm gear module range.

The LNET 18-M1.50-NO3-C IC908 insert has been designed for milling involute gear teeth according to standard DIN 3972 basic profile II, with 1.5 mm module and 17-20 tooth range.

Note: Other cutter diameters with alternative connection options (shank or arbor-types) or insert profiles within the mentioned module range can be provided on request.
