Expansion of the HELIIQMILL 390 Line with Tools Carrying 07 mm Edged Inserts

Highlights • Tools carrying triangular inserts with 7 mm long helical cutting edges • Effective and economical solution for milling 90º shoulders Following excellent market response to the HELIIQMILL 390 milling family, a new HM390 TCKT 0703PCTR smaller triangular insert was designed based on its predecessors HELIIQMILL 390 15 and 10 mm inserts - with all their advantageous features.

The new insert features a maximum depth of cut of 5 mm, providing the following advantages: Smaller tool diameters can be offered: 16 mm endmills and 32 mm face mills. Tools with higher tooth density Thick triangular inserts with 3 helical cutting edges Very rigid design Positive axial rake that reduces cutting forces Effective and economical solution for milling 90º shoulders Wiper flat for high surface finish Soft and clean cutting with long tool life The new HELIIQMILL 390 inserts are produced from ISCAR’s latest SUMO TEC carbide grades, which significantly increases productivity. Due to the...

Applications Machining main engineering materials: steel and cast iron, stainless steel and difficult-to-cut HTSA Milling shoulders, slots and plane surfaces Operations requiring ramp milling or helical interpolations Designed for general engineering parts Advantages • Productivity: high metal removal rates • Economy: inserts with 3 helical cutting edges • Accuracy: milling 90º square shoulders • Low power consumption that allows applying the cutters on machine tools with limited power • High process reliability Cutting Data Tables attached provide insert selection and cutting data recommendations...
