Machine Tap WHITE RING DIN 371 Form B HSSE VAP - M 8 x 1.25

• Perfect for stainless steel, chrome-nickel alloys and long-chipping materials
• Handles difficult-to-machine and abrasive materials up to 1000 N/mm²
• Form B spiral point design for safe chip evacuation in through holes
• HSSE material ensures durability, hardness and wear resistance
• VAP coating extends tool life and enhances process stability

The VAP coating makes a huge difference in practice. It improves how coolant and lubricant adhere to the tool, preventing film breakage and minimizing friction. This results in smoother cutting, less heat generation and reduced risk of cold welding on the cutting edges. For you, this means more reliable machining, cleaner threads and significantly longer tool life – especially important when working with stainless steels and high-alloy materials.

1. Drill the core hole: Use the correct diameter for your thread size and chamfer the edge slightly.
2. Secure the workpiece: Clamp it firmly and ensure proper alignment to avoid miscuts.
3. Mount the tap: Insert the WHITE RING tap in a tapping chuck and check concentricity.
4. Apply coolant: Add cutting oil or coolant. The VAP coating helps keep the lubricant film stable.
5. Cut the thread: Engage with synchronized feed; chips are pushed forward thanks to Form B geometry.
6. Finish: Reverse out carefully, deburr the hole and check the thread with a gauge or bolt.

Which materials can I use this tap for?
It is designed for stainless steel, chrome-nickel alloys and other hard-to-machine materials up to 1000 N/mm². If you’re working on demanding jobs, this tap is the right choice.

What is special about the VAP coating?
It improves lubrication, prevents cold welding and ensures longer tool life. You’ll notice smoother cutting and fewer interruptions during machining.

Why choose Form B?
Form B taps push chips forward, making them ideal for through-hole applications where clean chip evacuation is crucial.

Can I use this tap on CNC machines?
Yes, absolutely. With a synchronized or compensating tapping chuck, it works perfectly in CNC setups, ensuring precision and repeatability.

How can I maximize tool life?
Use plenty of coolant, stick to recommended cutting speeds and feeds, and check your tool regularly. This way you’ll get consistent, high-quality results for a long time.
