Iscar's Heliturn platform features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The revolutionary Heliturn is a tangentially clamped insert with a unique helical shaped cutting edge, useful for tremendous depths of cut and higher than normal feed rate. The LNMX...-HT Heliturn insert is screw-clamped into the SLANR tool holder and braced 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 the insert is mounted level with the top of the tool holder to facilitate chips to flow across the insert, without being disrupted by clamps or the tool holder body. The 4 curved helical cutting edges ensure positive radial rake angles and soft penetration into the material being cut. The reduced forces and smaller loads assure better tool life, more significant stability and the ability to use extremely considerable depths of cut and bigger feeds. The chipformer, distorts and breaks the chip into rib type curved segments which can easily be removed from the cutting area. This insert has a frontal clearance angle of 3.7 with a 6 side clearance angle to allow machining to a 90 shoulder. Depths of cut up to .315" and facing depths to .126" at up to .047" IPR are doable with Heliturn.

When contrasted to CNMG/M 16... or WNMG/M 13... insert sizes with the alike corner radius, much superior tool life can be predictable when using the LNMX 1506..-HT insert. Iscar has recently added 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 brand new insert features all of the advantages of the larger insert. This boosts the economical usefulness in the medium machining application compass. 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 predicted. The inserts are available in .031, .047 and .063" tool nose radii. Heliturn inserts are available in the most exceptional carbide grades: IC9025, IC3028 , IC428, IC907, and IC908.

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

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

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

A Completely 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 revolutionary insert has a very positive radial, helical cutting edge and a positive rake angle; a combination which substantially decreases the cutting forces. The insert's corner has a wiper configuration 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 heightened strength. The CNMX inserts were engineered for heavy machining applications. Their special design ensures reliable, 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 replaced with a special seat: TCH 4. Iscar's R-clamp tool holders are highly recommended for heavy machining applications.
