Machine Tap ISO 529 Form B HSS-G left hand thread - M 12 x 1.75 LH | VÖLKEL
Machine Tap ISO 529 Form B HSS-G left hand thread - M 12 x 1.75 LH
This machine tap is intended for internal thread cutting in metalworking tasks where the tool is guided by a suitable tap holder.
When the tool is specified with spiral flute or spiral point geometry, use that as your selection cue for chip transport direction and hole type. The execution follows ISO 529.
- Cut internal threads in pre-drilled holes using a controlled machine process.
- Use a machine tap holder, collet system, or tapping attachment suited to the tap shank and drive.
- Use the correct rotation direction for left hand threads and verify the setup before tapping.
- 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 Use cutting fluid suited to the workpiece material and keep the tool clean and protected after use.
- Fits typical tap holding systems appropriate to the tool type
- Makes selection easier by referencing standard, form, and thread designation
- Supports predictable lead-in when you align the tool to the hole axis
- Provides a defined chamfer form for consistent thread start
- Supports stable cutting edges for frequent use in service operations
Drawbacks
- Limited suitability for very hard materials unless a dedicated execution is specified
- Not suitable for uncontrolled hand tapping without a guided holder
- Confirm the thread designation and ensure the workpiece hole is prepared and free of burrs.
- Secure the workpiece so the hole axis is stable during the tapping cycle.
- Mount the tap in a suitable machine tap holder and check that the tool runs true.
- Apply cutting fluid suited to the workpiece material.
- Align the tool to the hole axis before you start the tapping cycle.
- Verify rotation direction for left hand threads before you engage the tap.
- Run the tapping cycle with controlled feed and observe chip evacuation.
- Reverse out under control when the required thread depth is reached.
- Clean the thread and the tool, then protect the cutting edges for storage.
Scope of supply is not specified in the provided product data for this item.
- Tool type: Machine tap
- Standard: ISO 529
- Chamfer form: Form B
- Tool material: HSS-G
- Thread direction: Left hand
- Thread system: ISO metric
- Tolerance class: 6H
- When should you use a machine tap instead of a hand tap
- Use a machine tap when you can guide the tool with a machine spindle and a suitable tap holder, and when you want controlled feed that matches the thread pitch.
- What holder type do you need for this tap
- Use a machine tap holder, collet system, or tapping chuck that supports the tap shank and keeps alignment to the hole axis stable.
- What preparation is required before you tap the thread
- Prepare the core hole to the correct size for the thread designation, remove burrs, and add a small lead-in chamfer so the tap can start without side load.
- How do you control chips and cutting fluid during tapping
- Use cutting fluid suited to the workpiece material and clear chips regularly, especially in deeper holes or tougher materials, to prevent chip packing and tool overload.
- Where can you find additional technical information for this execution
- Use the following PDF for reference on machine tapping basics: Technical information machine taps as PDF
- How do you reduce risk of tap breakage
- Keep alignment stable, avoid side load at entry, and stop if torque rises sharply so you can inspect hole preparation, lubrication, and chip evacuation.
- Where can you find more product and application information in the VÖLKEL catalog
- Use this catalog for additional details and related items: VD 23 catalog as PDF
- How do you inspect the thread after tapping
- Check that the thread is clean, that the start is not damaged, and that the functional fit matches the mating component used in your assembly.
