Threading tap KWB 443303 High-Speed Steel 40 mm Grey

The KWB 443303 threading tap is a high-speed steel (HSS) hand tap set designed for cutting and forming internal threads. Supplied as a 3-piece set with tapered, second and plug taps, it follows DIN 352 standards and is intended for use with tap wrenches and tool holders. With an overall length of 40 mm and a working length of 11 mm, the tool is suitable for creating precise threads in a variety of materials.

Advantages

Manufactured from high-speed steel for durability and wear resistance, this KWB tap set provides accurate thread geometry and reliable performance. Ground threads ensure smooth cutting action and consistent results. The three-tap sequence (taper, second, plug) allows progressive thread cutting for improved finish and reduced risk of tool breakage during hand tapping.

Suitable for

• Cutting internal threads in metal, alloy and some harder plastics
• Manual tapping with tap wrenches
• Use with tool holders for controlled tapping operations

How to use

Select the tapered tap first to start the thread, then continue with the second tap and finish with the plug tap for full-depth threads. Secure the workpiece, align the tap perpendicular to the hole, and use a suitable tap wrench or tool holder. Apply moderate cutting oil where appropriate, turn the tap clockwise to cut, and back off periodically to clear chips. Follow safe hand-tapping practices to avoid excessive torque and breakage.

Usage recommendations

Use appropriate cutting lubricant for the workpiece material, maintain correct alignment, and progress through the taps (taper → second → plug) to achieve accurate threads and extend tool life.
