HexTap Type S Threading Bit, 1/4" hexagon drive Form D HSS-G - M 8 x 1.0 | VÖLKEL
HexTap Type S Threading Bit, 1/4" hexagon drive Form D HSS-G - M 8 x 1.0
HexTap Type S Threading Bit, 1/4" hexagon drive Form D HSS-G - M 8 x 1.0 supports controlled thread cutting when you select it by thread system and apply it in a stable, guided setup. It fits typical shop workflows in machine building, service, and metal fabrication.
M denotes an ISO metric thread, common in mechanical engineering where metric drawings and tolerances are used. HSS-G means ground high speed steel, which is commonly used when you need stable cutting behavior and clean thread flanks.
- Hextap use in repair and small batch work, including service workshops and mechanical engineering.
- Thread production on prepared holes or blanks where alignment is controlled by a holder, guide, or machine spindle.
- Process: manual driving or assisted driving depending on your holder and machine setup
- Use: thread cutting, re tapping, and thread cleaning depending on condition
- Use suitable lubrication and remove chips regularly so cutting edges do not pack up.
- Thread system context: match the tool to the M specification stated on the part or drawing.
Note Clean threads and tools before use, apply suitable lubrication for cutting operations, and stop if resistance rises sharply.
- Direct selection by thread designation such as M when stated reduces setup mistakes.
- Suitable for workshop processes where alignment and controlled engagement are practical priorities.
- Supports consistent thread quality when you use steady feed and lubrication.
- Works well for maintenance tasks where parts must be reworked to the drawing requirement.
Drawbacks
- Not suitable for materials or hardness outside the typical range for the named tool material and execution.
- Not intended for high performance production without a validated process and rigid machine conditions.
- Prepare the hole or existing thread so entry is clean and burr free.
- Select a suitable holder and ensure the tool is aligned square to the thread axis.
- Apply suitable cutting lubricant and start the cut with steady rotation.
- Maintain even feed without side force so the tool follows the axis.
- Reverse briefly to clear chips from the flutes, then continue with controlled engagement.
- Stop when required depth is reached, then back the tool out completely.
- Clean the thread and tool, then protect the tool from corrosion for storage.

- How do you decide between a hand tap and a machine tap for this thread?
- You choose by the driving method and the stability of the setup. Hand taps support controlled manual work, while machine taps support guided or powered driving with stable alignment.
- What do you check before you start cutting the thread?
- Confirm the thread designation, the hole preparation, and the workpiece material. Keep alignment square to the axis and plan lubrication and chip evacuation.
- How do you reduce the risk of a tapered or oversize thread?
- Maintain alignment, avoid side load, and use steady feed. Clean chips from the cutting geometry and verify the first part against the specification.
- Where do you find the matching catalog for additional variants and reference data?
- Use the catalog for additional information and product family context: VD 23 catalog as PDF
- How do you choose the correct drill preparation without guessing values?
- Use a drill size chart that matches the thread system and the tool type. For inch based threads, confirm that the notation is interpreted correctly before drilling.
- When should you replace the tool instead of forcing it?
- Replace it if cutting torque rises abruptly, if the tool rubs without cutting, or if the thread surface becomes torn. Forcing a worn tool can damage the workpiece and the tool.
