CM7220 Carbide Turning Inserts For Stainless Steel Machining

We developed the CM7220 grade specifically because we know how tough stainless steel can be to machine. Shops often tell us that inserts wear down fast or chip easily when turning 304 or 316 parts, especially in high-volume runs.

This grade is balanced to handle that. The carbide substrate is paired with a heat-resistant coating to resist built-up edge and wear. We've run these inserts on dozens of 304 exhaust flanges and pipe fittings, and they hold their edge much longer than generic grades we've tried before.

The chipbreaker is tuned to keep chips under control. That means less tangling, cleaner cuts, and a smoother surface finish, which is important for sanitary fittings and parts where burrs aren't acceptable.

They fit standard tool holders, so you don't need to change your setup. You can use them for external turning, boring, or facing on most CNC lathes.

Where they work best:

• Automotive: Stainless steel exhaust parts, fasteners, and shafts
• Pipe & valve: Sanitary fittings, valve bodies, and pump components
• Medical & food equipment: Parts requiring smooth, consistent finishes
• General machining: Shafts, flanges, and custom parts in 304/316 stainless

What makes them different:

• Tuned specifically for stainless steel, not a one-size-fits-all insert
• Better heat and wear resistance helps reduce frequent tool changes
• Stable chip control for cleaner, burr-free parts
• Works with most standard lathe tool holders

Key details:

• Grade: CM7220 (optimized for stainless steel turning)
• Materials: 304, 316, and duplex stainless steels
  
• Common shapes: Triangle, diamond, and square profiles
• Coating: Wear-resistant layer to reduce adhesion and heat
