Round Die BS 1127 HSS - BA 1 x 28.22

• Cut external threads on rods, bolts, and studs in repair, prototyping, and small batch work.
• Use with a round die holder or die stock to keep the die square to the workpiece axis.
• Apply cutting fluid matched to your material to reduce friction and protect the thread profile.
• Process: manual driving or assisted driving depending on your holder and machine setup.
• Use: thread cutting, re tapping, and thread cleaning depending on condition.

Note Confirm thread system, pitch, and fit requirement before cutting. Prepare the workpiece with a clean lead in chamfer.

• Supports repeatable thread cutting in small batches with minimal setup.
• Good access in confined work areas compared with larger machines.
• Easy to clean and store as an individual tool.
• Works well for service tasks when the correct preparation is in place.

• Performance is limited in very hard or abrasive materials unless a suitable die execution is selected.
• Cycle time is limited for high volume production compared with dedicated machine processes.

1. Inspect the workpiece and ensure there is a clean lead in chamfer at the thread start.
2. Select a round die holder and clamp the die securely before you approach the workpiece.
3. Apply cutting fluid to the workpiece area and to the die entry side.
4. Align the die square to the workpiece axis and start cutting with steady forward pressure.
5. Turn the die forward to advance the thread while maintaining alignment.
6. Reverse briefly at intervals to clear chips from the cutting edges.
7. Continue until the required thread length is reached and then stop the forward feed.
8. Back the die off the workpiece and remove it from the holder.
9. Clean the die and verify the thread fit with a matching part or a suitable gauge.
