Key Features & Benefits
- M2 high-speed steel — best combination of strength, heat and wear resistance for cutting external threads in tough materials.
- Solid button design — fits any standard adjustable guide or plain die stock handle — no clamping screws to slip.
- More accurate than carbon dies — tighter tolerances mean threads mate squarely with off-the-shelf nuts.
- Bright finish — general-purpose surface suits ferrous and non-ferrous metals plus plastics.
- Australian made — manufactured by Sutton Tools at their Thomastown, Victoria plant.
When to Use This HSS Button Die
Use this button die when you need to cut a fresh external thread onto round stock, studding or a turned-down shaft — fitting the die into a die stock and rotating it over the workpiece. The HSS edge holds up against repeated production threading and tougher materials where carbon dies would dull quickly. This particular variant (M4141905) cuts a 3/4-2 UNC thread.
Pro Tip: Chamfer the leading 1–2 mm of the rod at roughly 30° before starting the die — this gives the cutting edges something to bite into and dramatically reduces the chance of starting a crooked thread. Use cutting fluid liberally and reverse a half-turn for every full turn forward to break the chip.
