SNMX120512-F67 WAK15 milling insert — 0° negative rake, 1.2 mm corner radius | Walter Tools

The SNMX120512-F67 WAK15 is a square 90° milling insert designed for machining aluminium and other non‑ferrous metals, offering a 0° negative rake and a 1.2 mm corner radius for stable, repeatable cutting.

• Uncoated carbide grade WAK15 for aluminium
• 0° negative rake for stable cutting
• Square 90° insert with 1.2 mm radius
• F67 chipbreaker for clean chip formation

Consistent, high‑quality results when machining aluminium

The SNMX120512‑F67 WAK15 is engineered for dependable performance in non‑ferrous machining. The WAK15 uncoated carbide composition provides a sharp, abrasion‑resistant cutting edge tailored to aluminium and similar materials, while the F67 chipbreaker prevents long, entangling chips and promotes efficient evacuation. The combination of sharp carbide and focused chip control reduces the risk of material adhesion and burr formation, which leads to improved surface finish and fewer secondary operations. For workshops aiming at predictable throughput, this geometry delivers measurable gains in process stability.

Stable cutting action through geometry and rake design

The insert’s 0° negative rake increases edge strength and supports secure engagement under interrupted cuts or heavier cross‑feeds, without compromising the quality expected for non‑ferrous components. The square 90° shape and 1.2 mm corner radius distribute cutting forces effectively, making the insert suitable for both shoulder and face milling tasks where robustness is required. These geometric choices reduce vibration and help maintain dimensional accuracy over longer production runs, thereby improving tool life and lowering the frequency of index changes.

Practical productivity benefits on the shop floor

Integrating this insert into standard milling holders yields straightforward setup and predictable cutting behaviour. The modest plate thickness and compact dimensions facilitate fine step‑downs and close tolerance work, while the optimized chipbreaker geometry supports higher feed rates typical for aluminium machining. As a result, cycle times can be shortened without sacrificing surface quality. The insert’s classification in the Walter N‑series denotes a focus on productive machining of non‑ferrous metals, making it a practical choice for job shops and production lines seeking efficient, repeatable results.
