RED RING TwinBox Machine Tap + Twist Drill DIN 376 HSSE-PM TiALN - M 16 x 2.0

• Cut internal threads in drilled holes for fasteners, fittings, and mechanical assemblies.
• Use in mechanical engineering, metal fabrication, and maintenance work where controlled threading is required.
• Start the tap square to the hole to reduce risk of cross starting and uneven flank load.
• 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 VÖLKEL uses and recommends spiral drills from LÖHER. LÖHER product catalog as PDF

• Controlled internal thread cutting with direct process feedback
• Suitable for repair work, prototyping, and general workshop machining
• Supports repeatable thread fit when the pre hole and alignment are correct
• Applicable across maintenance and production environments

• Not suitable for brittle or abrasive materials without adapted cutting strategy and tool choice.
• Manual or guided threading can be slow for high throughput applications.

1. Prepare the hole with a correct core diameter and a clean entry chamfer.
2. Secure the workpiece and align the tool square to the hole axis.
3. Apply suitable cutting lubricant for the material and process.
4. Start the tool with controlled torque until it is guided by the thread form.
5. Advance with steady turns or a guided feed while keeping alignment constant.
6. Withdraw the tool at intervals and clear chips from the flutes.
7. Continue until the required thread depth is reached, then remove the tool fully.
8. Clean the thread and check fit with a matching screw or gauge.

Where can you find an overview of TwinBox executions? Use the overview to understand the TwinBox concept and the scope of application. TwinBox overview as PDF How do you confirm that the thread system matches the mating part? Match the designation on the tool to the drawing and the mating fastener or gauge. For inch and pipe threads, confirm thread family and fit class before you start machining. Where can you find execution information for the ring variant? Use the execution sheet to understand the ring variant focus and use conditions. RED RING TwinBox as PDF What does the designation M 16 x 2.0 mean on this tool? It defines the thread family and size that the tool is designed to produce or inspect. Use it only on matching parts and avoid mixing similar inch series. How do the material and coating designations affect selection? These designations describe tool material and surface treatment. Use them to match wear resistance and toughness needs to your material and process, without changing thread geometry. Where can you find catalog information for this product family? Use the product catalog for overview tables and selection context. VD 23 catalog as PDF
