Machine Tap JIS B-4430 Form C 35° Spiral Flute | VÖLKEL
Machine Tap JIS B-4430 Form C 35° Spiral Flute HSSE - UNF 5/32 x 36
This machine tap is intended for internal thread cutting where you need repeatable alignment and a tool matched to the thread designation shown in the product name. It suits workshop production and repair work when the holder and machine setup allow controlled feed and reversal. The named geometry helps you choose the tool for the hole condition and thread system.
UNF means Unified National Fine, an inch thread series used when a finer pitch is required for adjustment, clamp control, or limited wall thickness. HSSE or HSS-E indicates cobalt alloyed high speed steel, which supports hot hardness and wear resistance under more demanding cutting conditions. Form C in this context identifies a tool geometry aligned to the stated tapping application and hole condition. Spiral flute geometry is commonly chosen where chip flow must be directed out of the threaded hole during internal thread cutting. JIS B standard identification shows that the tool follows a Japanese industrial standard family for the stated tap type.
- Use in workshop production, maintenance, and fabrication where the stated thread designation must be matched accurately.
- Select the tool by the thread system, size, and form stated in the product name before the job begins.
- Process: manual driving or assisted driving depending on your holder and machine setup
- Use: thread cutting, re tapping, and thread cleaning depending on condition
- Keep the hole type and tap geometry aligned so chip flow follows the intended tapping application.
Note Confirm thread designation, holder concept, and workpiece condition before you start the operation.
- Geometry and standard are already matched to the stated thread designation.
- Machine controlled use supports repeatability in series work and repair jobs.
- The named flute form helps you align the tool choice with the hole condition.
- HSSE or HSS tool material supports practical durability in thread cutting work.
Drawbacks
- Performance depends on correct alignment, lubrication, and the intended hole condition for the named geometry.
- It is not intended to solve process problems caused by unsuitable machine synchronization or poor hole preparation.
- Confirm that the thread designation and the hole type match the machine tap named in the product title.
- Prepare the tapping hole and secure the workpiece so alignment remains stable throughout the operation.
- Clamp the tap in a suitable holder that supports concentric guidance and controlled reversal.
- Apply cutting fluid suited to the workpiece material and the tapping process.
- Cut the thread with controlled feed so the tap follows the hole axis and the intended geometry.
- Reverse the tap carefully, clear chips from the hole, and inspect the finished thread before assembly.

- How do you choose the correct product variant?
Match the thread designation, standard, and execution from the product name to the drawing or the existing mating thread before you start the job.
- How do you decide whether the product fits your process?
Check whether you need manual handling, assisted driving, or a controlled machine process, and confirm that the product type in the name matches that use case.
- What should you inspect before the threading operation?
Inspect hole or workpiece condition, alignment, lubrication plan, and holder suitability so the tool can work under controlled conditions.
