Threading tap KWB 443306 High-Speed Steel Grey 50 mm

The KWB 443306 threading tap is a three-piece set of high-speed steel (HSS) taps designed for forming internal threads. Manufactured to DIN 352 standards, the set includes a taper, a second, and a plug tap with ground threads. With an overall length of 50 mm and a working length of 19 mm, these grey-finished taps are intended for hand use with tap wrenches and tool holders and are suitable for thread cutting in a variety of materials.

Advantages

The HSS material provides wear resistance and maintains cutting performance over repeated use. Ground threads ensure accurate, clean thread formation and smoother engagement. The three-step set (taper, second, plug) allows progressive thread cutting to reduce the risk of breakage and to achieve full-thread depth reliably. Compliance with DIN 352 gives dimensional consistency and interchangeability for matching tooling.

Suitable for

• Creating internal threads in metal, alloy, and other machinable materials
• Hand tapping with tap wrenches
• Use with tool holders or fixtures for guided tapping

How to use

Secure the workpiece and select the appropriate tap from the set (start with the taper tap, then the second, and finish with the plug tap). Use a suitable tap wrench or a tool holder to keep the tap aligned and apply steady, controlled rotation. Lubricate the tap and cutting area according to the workpiece material to reduce friction and improve chip evacuation. Back off periodically to break chips and prevent clogging or binding.

Usage recommendations

Use cutting fluid appropriate for the material being tapped, maintain alignment to avoid crooked threads, and replace taps that show significant wear or damage. Store the set dry and clean to prevent corrosion and preserve thread quality.
