New 90° Cutters Carrying Tangentially Clamped Inserts with 8 Cutting Edges
Highlights
Following a clear market demand for economical solutions, ISCAR is introducing new cutters that carry tangentially clamped inserts with 8 right-hand cutting edges.
The cutters are intended for face and shoulder milling. They are suitable for different types of steel, stainless steel and cast iron, and are designed for roughing and finishing operations in the automotive, die and mold industries and for general engineering.
The new T890HT cutters are available in the following configurations:
- T890HT ELN Endmills in 32 and 40 mm diameters with cylindrical and Weldon shanks
- T890HT FLN Face mills in 40, 50, 63, 80, 100 and 125 mm diameters with coarse and fine pitch
Tool Features
- 90º cutting edge angle
- Coarse- and fine-pitch configurations
- Coolant channels directed to each cutting edge
- Rigid dovetail clamping configuration
- Polished coating of the cutter body facilitates chip flow and protects against corrosion and wear
Applications
- Suitable for different types of steel, ferritic and martensitic stainless steel and cast iron
- The endmills and face mills are intended for machining square shoulders, slots and face milling
Insert Features
T890 LNHT 1306PNTR - an insert for general use:
- Four-sided tangentially clamped insert with 8 right-hand cutting edges
- 0.8 mm corner radii
- 9.5 mm maximum depth of cut
T890 LNAT 1306PN-W- a wiper insert with 4 cutting edges for finishing operations:
- Wiper for high surface quality
- 0.6 mm x 45 deg. chamfer
The new inserts are produced from ISCAR’s latest SUMO TEC carbide grades, which significantly
increase productivity.

Machining recommendations for T890HT-13 cutters
* ISCAR material group in accordance with VDI 3323 standard
** Quenched and tempered
For machining in unstable conditions, the recommended cutting data should be reduced by 20-30%
IC830 is a general purpose grade and it may be considered as the first-choice grade
IC845 is recommended for milling at relatively small depths of cut and for interrupted cutting applications
IC5500 is intended mainly for milling ferritic and martensitic stainless steel at increased speed
