Machine Tap JIS B-4430 Form C 35° Spiral Flute HSSE - Rp (BSPP) 2" x 11

• Machine Tap use in repair and small batch work, including service workshops and mechanical engineering.
• Thread production on prepared holes 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 Rp (BSPP) 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 Rp (BSPP) reduces setup mistakes.
• Suitable for workshop processes where alignment and controlled engagement are practical priorities.
• Robust tool basis through the named HSSE cutting material.
• 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.

• If the base thread is severely damaged, re-tapping alone is often not sufficient; for durable repair solutions, check VÖLKEL thread repair.

1. Prepare the hole or existing thread so entry is clean and burr free.
2. Select a suitable holder and ensure the tool is aligned square to the thread axis.
3. Apply suitable cutting lubricant and start the cut with steady rotation.
4. Maintain even feed without side force so the tool follows the axis.
5. Reverse briefly to clear chips from the flutes, then continue with controlled engagement.
6. Stop when required depth is reached, then back the tool out completely.
7. 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 does Rp (BSPP) mean for this product?

Rp (BSPP) denotes a parallel pipe thread system. Match the thread designation to the drawing, counterpart, and sealing concept before machining.

What does HSSE mean for this machine tap?

HSSE denotes a cobalt-alloyed high speed steel tool material with good cutting durability for demanding threading work.

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.
