Product catalog summary

New Product Announcement: SUMOMILL T290 Extended Flute Shell Mill Cutter

Features:

The cutter has a 50 mm diameter and uses T290 LNMT 150608TR inserts.
Its tangential orientation allows for a larger core diameter, enhancing tool strength and reducing fracture risk.
Helical cutting edges and positive rake angles provide a soft, clean cut.
Design reduces cutting forces, improves stability, and extends cutting edge life.
Capable of high table feeds with excellent surface finish.
Equipped with coolant holes for improved performance and chip evacuation.
HARD TOUCH coating ensures smooth chip flow and protection against corrosion and wear.

Applications:

Suitable for all steel, cast iron, stainless steels, and difficult-to-cut materials.
Ideal for shoulder and slot milling operations.
Applicable in general engineering, aerospace, and power generation industries.

Advantages:

High metal removal rates even on low-power machines due to high axial positive cutting angles.
Reduces machining costs for high shoulder milling.
Ensures high process reliability.

Machining Examples:

SAE 4340 28 HRc: Cutting speed 150 m/min, feed per tooth 0.15 mm/t, tool life 40 min, metal removal rate 452 cm³/min.
Stainless Steel AISI 316L - 168 HB: Cutting speed 160 m/min, feed per tooth 0.1 mm/t, tool life 40 min, metal removal rate 321 cm³/min.
