The Expansion of the HELI3MILL 390 LINE with a New Serrated Cutting Edge Insert
An assembly instruction:
Highlights
A new serrated cutting edge geometry for highly efficient rough milling.
ISCAR expands its advantageous HELI3MILL 390 LINE by introducing new inserts with
serrated edges.
The new inserts, with a radii of 0.8mm and 3.2mm designated as HM390 TDCR 1505…FW-P,
feature a super positive and sharp serrated cutting-edge geometry with polished rake surfaces
which assure highly efficient milling for aluminum alloys and other non-ferrous materials.
(ISO N grade of application)
The insert’s cutting-edge geometry splits the chips into small pieces and generates low cutting
forces enabling increased feed rates for higher machining productivity.
Features
A sharp serrated cutting edge with a special chip former;
- significantly improves chip evacuation
- reduces cutting load and enables high table feed
- reduces vibration
- reduces heat generation
Suitable for High Speed Machining (HSM)
Intended for 90° milling cutters
Peripherally ground insert
Wide sharp-edged wiper for improved surface finish
Both rake and relief surfaces are polished
Cutting recommendations Table - Averaged Cutting data for HM390 TDCR 1505...FW-P inserts
* ISCAR material group in accordance with VDI 3323 standard
** Euronorm
For machining in unstable conditions, the recommended cutting data should be reduced by 20-30%
Applications
Rough to finish machining for ISO N materials
Milling square shoulders, slots, inclined surfaces and cavities by ramp down including ramping by helical interpolation
Milling with high tool overhang
Benefits
Productivity: Assures high metal removal rates
Economical: 3 helical cutting edges
Accuracy: milling 90º square shoulders
High performance when milling at low unstable conditions
Low power consumption allows applying the cutters on machine tools with limited power, small capacity machining centers and turn-milling machines
The shredded chips help in a significant reduction of the common built-up phenomena, especially when machining aluminum alloys
This single-sided triangular insert has three positive and serrated cutting
edges intended for milling at 13mm depth of cut
Inserts with a large corner radius produce large chips. A shred feature was added
to the 3.2mm radius.
The inserts feature a wiper corner edge for high surface finish
New and easy to assemble as shown in the video
Light weight inserts for HSM where high metal removal rate (MRR) is required

Product operation guidelines
In order to provide overlapping and achieve optimal chip shredding, it is recommended to mount the HM390 TDCR 1505… FW-P insert in an alternating edge configuration on adjacent cutter flutes.
