HexTap - Double ended tap + round dies (set of 26 pcs.) M 3 – M 24

• Cut new metric ISO internal threads in prepared holes with the HexTap double ended taps when the selected M size matches the required thread.
• Clean or restore damaged internal metric threads if the existing thread profile still allows controlled re tapping.
• Cut external metric threads on prepared rods, studs, bolts, and blanks with the matching round dies.
• Use the set for service work, mechanical repair, prototype construction, fitting work, and maintenance tasks where several metric sizes are needed at the workbench.
• Select the internal or external tool first, then select the exact metric size before starting the cut.
• Use suitable holders and stable guidance so the tap or die starts square to the thread axis.
• 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 Prepare the core hole or blank correctly, remove burrs before cutting, apply suitable cutting fluid, and stop the operation if torque rises sharply or the tool begins to run off axis.

• One set covers internal and external metric ISO thread work, so repairs to both sides of a threaded connection can be handled from the same kit.
• The M 3 to M 24 range supports many common workshop sizes used in mechanical engineering, assembly, maintenance, and service work.
• HexTap double ended taps are practical for controlled internal thread work where a compact tool format is useful.
• Round dies make external thread cutting and thread restoration possible on prepared cylindrical workpieces.
• The linked scope of supply makes each component traceable, which helps when replacement tools must be identified later.

• Thread quality depends on correct tool alignment, prepared workpiece geometry, lubrication, and controlled feed.
• The set is not a substitute for dedicated production tooling where fixed machine processes, cycle time, and tool life validation are required.

1. Identify whether the workpiece needs an internal thread or an external thread.
2. Select the HexTap double ended tap for an internal thread or the round die for an external thread.
3. Match the selected tool size to the drawing, the mating component, or the existing metric thread.
4. Prepare the core hole or blank and remove burrs from the thread start area.
5. Clamp the workpiece securely so the thread axis remains stable during cutting.
6. Mount the selected tool in a suitable holder or guided setup.
7. Apply cutting fluid matched to the workpiece material.
8. Start square to the workpiece axis and continue with controlled torque.
9. Clean the finished thread and verify engagement with the mating part or a suitable gauge.

What is this 26 piece HexTap set used for?

This set is used for cutting and restoring metric ISO internal and external threads from M 3 to M 24 in workshop, maintenance, and repair work.

When should you use a HexTap double ended tap from the set?

Use a HexTap double ended tap when you need to cut or clean an internal metric thread in a prepared hole and the selected M size matches the required thread.

When should you use a round die from the set?

Use a round die when you need to cut or restore an external metric thread on a prepared rod, bolt, stud, or blank.

How do you select the correct component from the set?

Decide first whether the task is internal or external threading, then choose the matching M size from the tap group or die group.

What does Metric ISO mean in this product context?

Metric ISO identifies thread sizes marked with M and used across general engineering, fastening, maintenance, and assembly applications.

Why does the scope of supply include linked product numbers?

The linked product numbers identify the individual taps and dies included in the set, which helps you find replacement tools or check the component structure later.

What should you check before cutting an internal thread?

Check the core hole, remove burrs, confirm the selected M size, and make sure the tap can start straight in the prepared hole.

What should you check before cutting an external thread?

Check the blank preparation, chamfer the start area, confirm the selected M size, and keep the die square to the workpiece axis.
