This is the real test. Titanium loves to gall and weld to cutting edges. The Arkand-Protect coating plus the high cobalt’s toughness meant I could run at 120 SFM (aggressive for Ti with cobalt HSS, not carbide) with a .0015" chip load. No built-up edge after 45 minutes of roughing. The edge retention was surprising—I saw about 30% longer tool life compared to a leading brand’s premium cobalt series. scs tool platinum arkand series
They use a multilayer AlTiN + Si (Silicon) coating, branded as "Arkand-Protect." In practice, it’s a dark purple/bronze hue (not the usual black). The silicon layer is key here: it provides a higher hot hardness ceiling, allowing for dry or near-dry machining up to 1100°C interface temps without catastrophic coating failure. 2. Performance in the Wild (Stainless, Titanium, and Hardened Steel) I tested the 1/2" 4-flute variable helix end mill and a 3/8" coolant-through drill. No built-up edge after 45 minutes of roughing
You’ll know it’s different. The grind is harder—you feel the resistance. That’s the wear resistance talking. The silicon layer is key here: it provides
Let’s break down what this series actually is, who it’s for, and whether the premium price tag delivers real shop-floor ROI. First, let’s clear up a misconception. The "Arkand" name isn’t just marketing fluff. SCS claims it’s a proprietary powder-metallurgy cobalt blend (think M42 on steroids, but with a finer, more uniform carbide structure). Standard M35 has ~5% cobalt; M42 has ~8%. The Arkand series reportedly sits in the 9-10% cobalt range , but with a vanadium carbide refinement process that reduces grain size.
