## Summary description

FANAR GWINTOWNIK UNC 5/16-18 DIN 371B (2B) HSSE 800 is a machine tap for forming UNC 5/16-18 threads. Manufactured to DIN 371B with 2B tolerance, made from HSSE 800 high-speed steel for wear resistance. Suitable for use in thread cutting operations on compatible materials, for production and maintenance tasks requiring UNC coarse threads.

## Long description

FANAR GWINTOWNIK UNC 5/16-18 DIN 371B (2B) HSSE 800 is a machine tap designed to cut or form UNC 5/16-18 coarse threads in tapped holes. Manufactured to DIN 371B with 2B tolerance, this high-speed steel (HSSE 800) tap offers improved wear resistance and dimensional stability for repetitive production and maintenance operations. The tool is intended for use in machine tapping or hand tapping fixtures where standard UNC threads are required.
Advantages
The HSSE 800 material provides enhanced hardness and toughness compared with conventional high-speed steels, resulting in longer tool life under moderate cutting conditions. Conformance to DIN 371B and 2B tolerance ensures consistent thread fit and interchangeability with standard UNC fasteners. The tap's geometry is optimized for reliable chip evacuation and reduced risk of jamming during through and blind hole tapping when used with proper cutting fluid and machinist practice.
Suitable for
Cutting or forming UNC 5/16-18 threaded holes in production and repair work
Machine tapping operations in drilling/tapping machines and CNC setups
Hand tapping in jigs and fixtures where DIN 371B 2B tolerance is required
Applications where wear-resistant HSSE tools extend maintenance intervals
Key specifications
Thread standard: UNC 5/16-18 coarse thread
Design standard: DIN 371B (machine tap)
Tolerance class: 2B (internal thread fit)
Material: HSSE 800 (high-speed steel with enhanced alloying for wear resistance)
Intended use: machine and hand tapping for threaded holes
How to use
Secure the workpiece and align the tap with the hole axis before starting. Use an appropriate pilot drill size for UNC 5/16-18 threads and ensure the hole is properly deburred. For machine tapping, set correct spindle speed and feed to match material and tap size; for hand tapping, apply steady axial pressure and reverse the tap periodically to break chips. Use suitable cutting fluid to reduce friction and improve chip flow. Inspect threads after tapping to verify dimensional fit and surface condition.
Usage recommendations
Choose cutting speeds and feeds according to the workpiece material; lower speeds for stainless steels and harder alloys, higher speeds for softer non-ferrous materials. Replace taps that show excessive wear, chipping, or loss of thread quality. Store the tap in protective packaging to avoid edge damage and contamination.
