Description

TwinBox HexDrive Machine Tap + Twist Drill, DIN 371, Form C 15° RSP, HSS-E, M 5 x 0.8

With this TwinBox, you work with a coordinated tool pair for producing internal threads. The advantage lies in the clear workflow from drilling to thread cutting, because the drill and tap are already assigned together. For selection, you check the thread system, standard, form and the size stated in the product name.

For technical classification, read the product name from left to right: TwinBox designates the product group, M the metric thread system and DIN 371 the standard-related design of the tap. Form C 15° RSP identifies a right-hand spiral version for blind hole threads. HSS-E stands for the tool material, HexDrive for the hexagonal drive in the matching holder.

Application

Suitable when the core hole and internal thread are to be prepared with assigned 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.

Advantages

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.

Step by step

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.

Frequently Asked Questions (FAQ)

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.
