BLUE RING Machine Tap Set, DIN 371/376, HSS-E-TiCN, M 3-12 Form B

The BLUE RING Marking – Your Expert for Hardness

The BLUE RING marking on the shank of the taps signals that these tools are designed for machining high-strength and tough steels. VÖLKEL uses this marking to offer you a product specifically optimized for these challenging materials.

HSS-E-TiCN – Hardness and Wear Resistance

This set is made from HSS-E (High-Speed Steel with Cobalt) and is additionally refined with a TiCN coating. This coating provides excellent wear resistance through improved surface hardness and toughness. This ensures a significantly longer tool life, making them a reliable partner in cutting.

Important: The TiCN coating requires intensive and optimal cooling, as it has a lower heat resistance than other coatings. Therefore, be sure to ensure proper coolant supply to guarantee the maximum performance and service life of the taps.

Form B – Precision for Through Holes and Blind Holes

The lead Form B (4-5 threads) is ideal for most threading applications. This geometry allows for a smoother cut and is therefore suitable for both through holes and blind holes. It offers a balanced compromise between cutting force and chip formation and is especially useful when you need a versatile tool that can be used in various situations.

Q: What is the main advantage of the TiCN coating?

A: The TiCN coating provides increased surface hardness and toughness, leading to excellent wear resistance. This significantly extends the tool's service life, especially when machining tough and abrasive materials.

Q: Can I use these taps without coolant?

A: No, the TiCN coating has a lower heat resistance than other coatings. Intensive and optimal cooling is therefore absolutely necessary to prevent overheating and thus damage to the tool.

Q: What type of holes is Form B best suited for?

A: Form B is a very versatile geometry that is excellent for both through holes and blind holes.

Q: What is the difference between this set and the BLUE RING set with Form C?

A: The main difference lies in the geometry of the lead. Form B is a more universal lead, while Form C (with a right-hand spiral) is particularly optimized for chip evacuation in blind holes. The set described here also has a wear-resistant TiCN coating.
