Iscar's Heliturn platform features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The brand new Heliturn is a tangentially clamped insert having a distinctive helical shaped cutting edge, useful for tremendous depths of cut and greater than normal feed rate. The LNMX...-HT Heliturn insert is screw-clamped into the SLANR tool holder and held by the TLN ..-HT carbide seat. This seat has ground surfaces on the top and bottom, to provide perfect contact of the insert with the tool holders. The upper rake face of this insert is mounted level with the top of the tool holder to facilitate chips to flow across the insert, without being afflicted by clamps or the tool holder body. The 4 curved helical cutting edges provide positive radial rake angles and soft penetration into the material being cut. The reduced forces and smaller loads establish better tool life, considerably more stability and the ability to use extremely large depths of cut and bigger feeds. The chipformer, deforms and breaks the chip into rib type curved fragments which can quickly be removed from the cutting area. This insert has a frontal clearance angle of 3.7 with a 6 side clearance angle to permit machining to a 90 shoulder. Depths of cut up to .315" and facing depths to .126" at up to .047" IPR are attainable with Heliturn.

When contrasted to CNMG/M 16... or WNMG/M 13... insert sizes with the same corner radius, much superior tool life can be envisioned when using the LNMX 1506..-HT insert. Iscar has recently released a smaller size to the Heliturn family - the LNMX 1104..R/L-HT insert and tool holder for the common application range of up to .197" depth of cut. The completely new insert features all of the advantages of the larger insert. This enhances the economical usefulness in the medium machining application range. When compared to CNMG/M 43. 12... or WNMG/M 43. 08... insert sizes with the same corner radius, a considerably better tool life can be expected. The inserts are offered in .031, .047 and .063" tool nose radii. Heliturn inserts are presented in the most exceptional carbide grades: IC9025, IC3028 , IC428, IC907, and IC908.

The external tool holders are obtainable in 1, 1.25 and 1.5" shank sizes. Boring bars are available in 1, 1.25 1.5 and 2" bar sizes. Also obtainable are exchangeable heads. These tool holders have Iscar's unique Hard Touch coating, which enhances/increases/expands/heightens/stretches holder life and resists corrosion. As a result of the location of this insert, machining next to the tailstock is achievable.

The high positive rake angle of these cutters allows 10-15% less power usage than normal tool holders at the same parameters.

By utilizing Iscar's Heliturn tools, huge cost savings and profitability in lathe procedures is insured.

A New 80 Degree Rhombic Insert with high helical cutting edge for high metal removal rates Iscar is launching the CNMX 1207..-HTW insert family. The brand new insert has a very positive radial, helical cutting edge and a positive rake angle; a blending which substantially decreases the cutting forces. The insert's corner has a wiper arrangement which produces high surface finish even at high feed conditions, which in numerous occasions can take out a finishing cut. The corner angle is 88 degrees which provides increased strength. The CNMX inserts were engineered for heavy machining applications. Their distinctive design ensures reputable, fast metal removal when using 80 degree rhombic inserts. They can be mounted on any standard tool holder that carries typical CNMG inserts, but the seat has to be substituted with a special seat: TCH 4. Iscar's R-clamp tool holders are highly recommended for heavy machining applications.
