TwinBox HexDrive Machine Tap + Twist Drill, DIN 371, Form C 15° RSP, HSS-E, M 6 x 1.0 | VÖLKELTwinBox HexDrive Machine Tap + Twist Drill, DIN 371, Form C 15° RSP, HSS-E, M 6 x 1.0
The TwinBox is intended for workflows in which the core hole and internal thread are prepared using coordinated tools. This reduces the risk of an unsuitable twist drill or a mismatched tap entering the process during operation. Especially in mechanical engineering and workshop environments, this clear assignment matters in day-to-day use.
In this set, the thread system, standard and form define the application range. M designates the metric ISO thread, DIN 371 serves as the standard reference and Form C 15° RSP indicates a version for blind hole threads. HSS-E supports wear resistance and hot hardness, while HexDrive ensures a positive-fit connection to the holder.
- Suitable when the core hole and internal thread are to be prepared with matched tools in a coordinated workflow.
- M stands for a metric ISO thread and makes selection easier in mechanical engineering, workshop use and maintenance.
- Form C 15° RSP is typically chosen for blind hole threads and supports chip flow out of the hole.
- Process: manual or assisted drive depending on your tool holder and machine configuration.
- Use: thread cutting, re-cutting threads and cleaning threads depending on the condition of the thread.

- TwinBox keeps the twist drill and machine tap together as a fixed combination for the same workflow.
- HexDrive supports quick tool changes and positive-fit power transmission in the matching holder.
- DIN 371 makes the design easier to classify technically compared with other versions.
- HSS-E is designed as a tool material for durable threading work in industrial environments.
Disadvantages
- If your process is explicitly designed for through threads with a different chamfer form, Form C 15° RSP is not the first choice.
- Before series production starts, the set does not replace checking the holder, lubrication and axis alignment.
- First check the product name, thread system, standard and form so that the set matches the intended task.
- Clamp the workpiece securely and align the machining position so that drilling and thread cutting can be carried out on the same axis.
- Insert the twist drill into the matching holder and ensure a smooth, controlled start.
- Produce the core hole with even feed and then withdraw the drill cleanly from the hole.
- Clean the prepared hole and remove residues from the holder and workpiece before using the second tool.
- Change to the machine tap and check again that it is firmly seated in the HexDrive holder.
- Guide the tap axially and cut the internal thread with controlled movement according to your machine or holder.
- Turn the tool out cleanly, remove residues and then check the thread for an even profile.

- What do you use a TwinBox for in the workflow?
- You use it when the core hole and thread cutting are to be prepared with matched tools and both tools should be available together.
- What does M mean on this product?
- M stands for a metric ISO thread. This makes systematic thread identification easier for selection and replacement purchasing.
- What role does DIN 371 play?
- DIN 371 is the standard reference for the design of the machine tap. This allows you to classify the version technically in a comparable way.
- How do you classify Form C 15° RSP?
- Form C 15° RSP identifies a right-hand spiral design that is typically used for blind hole threads. This clearly distinguishes the set from use on through threads.
- What does HSS-E describe in this set?
- HSS-E designates the tool material of the machine tap. Conceptually, this version stands for increased hot hardness and durable use in the threading process.
- Why is HexDrive important for the application?
- HexDrive describes the hexagonal holder interface. It is useful when your holder is designed for positive-fit power transmission and quick changes in the workflow.
- Why is the twist drill included in the TwinBox?
- The twist drill is assigned to the tap as the preparatory tool. This keeps the process from core hole to finished internal thread organized in one clear tool combination.
