DLC Coated 3-Flute Long Carbide End Mill Featuring Chipbreaker Geometry for Enhanced Efficiency
TOYOKAWA, AICHI, JAPAN―December 17, 2025―OSG Corporation today announced the expansion of its milling cutter lineup for non-ferrous materials with the introduction of the AE-TL-N (-N), a DLC coated, three-flute long carbide end mill designed with chipbreaker geometry for uninterrupted machining.
Non-ferrous materials offer excellent machinability, enabling high-efficiency processing. However, during machining, large volumes of chips can accumulate on the machine table or bed, potentially affecting stability and overall productivity. The AE-TL-N (-N) addresses this challenge with a chipbreaker geometry that breaks cutting chips into small, manageable pieces, allowing easy evacuation by air or cutting oil. Additionally, the incorporation of a radius (R) at the chipbreaker corner helps prevent chipping and reduces streaks on the machined surface. By minimizing chip accumulation, machine downtime can be significantly reduced, contributing to improved efficiency and energy conservation.
The AE-TL-N (-N) is available in square and radius styles. Square style options include lengths of cut in 3xD and 5xD, with diameters ranging from 6 mm to 20 mm, totaling six items per length. Radius style options also include lengths of cut in 3xD and 5xD, with diameters from 6 mm to 20 mm, totaling 19 items per length.
