Key Features & Benefits
- Australian-made HSS blank. Manufactured at Sutton’s Thomastown facility — consistent quality and dimensional accuracy across the run.
- M42 HSS-Co body. M42 HSS-Cobalt for higher heat resistance and tougher workpieces — grinds to a clean cutting edge and holds it through long production runs.
- Precision-ground square section. Square-ground 5/16″ blank seats flat in any matching tool holder for repeatable centre-height setup.
- Grind-to-suit blank. Supplied unground so you can shape it for turning, facing, parting, threading or form work as the job demands.
- 75mm working length. Enough material for repeated regrinds without becoming too short to clamp securely.
When to Use This Tool Bit
Reach for this 5/16″ square blank when you need to grind a custom turning, facing or parting tool for your engineering or hobby lathe. Best matched to a tool holder accepting 5/16″ square shanks. The M42 cobalt grade is the right pick when cutting stainless, tool steels, or any workpiece that runs hot or work-hardens — it holds its edge where plain HSS would burn out.
