## Summary description

FANAR GWINTOWNIK UNF 1/4-28 DIN-2181/2 (2B) HSS is a high-speed steel (HSS) hand or machine thread tap for creating UNF 1/4-28 threads according to DIN 2181/2. Designed for cutting internal threads with a 2B tolerance class, it suits steel, non-ferrous metals and some plastics. Typical uses include maintenance, repair and precision machining tasks.

## Long description

FANAR GWINTOWNIK UNF 1/4-28 DIN-2181/2 (2B) HSS is a high-speed steel tap made for cutting internal UNF 1/4-28 threads to DIN 2181/2 with a 2B tolerance class. Intended for hand or machine use, this HSS tap produces precise internal threads in steel, non-ferrous metals and selected plastics. The tool is suitable for maintenance, repair and precision machining where UNF 1/4-28 threads are required.
Advantages
The HSS material provides a balance of toughness and wear resistance appropriate for a wide range of engineering materials. Conformance to DIN 2181/2 ensures thread geometry compatibility and a consistent 2B tolerance class for reliable assembly. The tap's design supports both hand and machine operation, enabling flexible use in workshop and field conditions. Its suitability for steel, aluminium and certain plastics reduces the need for multiple specialized taps.
Suitable for
Cutting internal UNF 1/4-28 threads in steel components
Threading aluminium and other non-ferrous metal parts
Repairing threaded holes during maintenance tasks
Precision machining where DIN 2181/2 thread form and 2B tolerance are required
Hand tapping or use in tapping heads on machining centres
Key specifications
Thread standard: UNF 1/4-28 to DIN 2181/2
Tolerance class: 2B (internal)
Material: high-speed steel (HSS)
Intended use: hand or machine tapping
Recommended materials: carbon steel, alloy steel, aluminium, non-ferrous metals, selected plastics
How to use
Secure the workpiece and ensure the hole diameter matches the recommended pilot drill for UNF 1/4-28. Use appropriate cutting fluid for the work material to reduce friction and extend tap life. For hand tapping, align the tap square to the hole and apply steady, even pressure while turning; periodically reverse the tap a half turn to break chips. When using a machine or tapping head, select correct spindle speed and feed to match the material and tap size, and monitor torque to avoid breakage.
Usage recommendations
To maximize tool life and achieve consistent thread quality, use fresh cutting fluid, avoid excessive feed or speed, and clear chips frequently. Inspect the tapped threads for proper fit and finish after cutting; ream or deburr the entry if necessary. For brittle plastics or very thin-walled components, consider using a dedicated tap geometry or lower cutting speeds.
