When to Use This Carbon Steel 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. Carbon steel dies are well suited to hand threading and general workshop use in mild steel, brass and aluminium. This particular variant (M4202223) cuts a 7/8-2 BSW 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.
