## Summary description

FANAR GWINTOWNIK UNC 3/4-10 DIN 376C R40 (2B) HSSE 800 is a UNC thread forming tap manufactured to DIN 376C dimensions. It cuts 3/4-10 UNC threads and is made from HSSE 800 tool steel for wear resistance. The R40 flute/profile and 2B tolerance designation define connection fit; suitable for machining internal UNC threads in repair and production environments.

## Long description

FANAR GWINTOWNIK UNC 3/4-10 DIN 376C R40 (2B) HSSE 800 is a machine tap produced to DIN 376C dimensional standards for forming and cutting internal UNC threads. Designed for 3/4-10 UNC thread size, this tap is made from HSSE 800 high-speed steel with cobalt for enhanced wear resistance and heat tolerance. The R40 flute/profile and 2B tolerance designation provide the intended fit and finish for standard internal connections in repair and production operations.
Advantages
The HSSE 800 material increases tool life under demanding cutting conditions and provides improved resistance to abrasion and thermal softening compared with conventional high-speed steels. The DIN 376C geometry ensures dimensional compatibility with standard UNC threaded components, while the R40 flute/profile supports efficient chip formation and evacuation in typical internal tapping tasks. The 2B tolerance facilitates reliable mating with external UNC threads manufactured to the same standard.
Suitable for
 Cutting internal 3/4-10 UNC threads in metal components
 Repair and maintenance of threaded assemblies in industrial equipment
 Production and small-series machining of UNC threaded bores
 Applications requiring a 2B class internal thread fit
Key specifications

 Thread size: 3/4-10
 Dimensional standard: DIN 376C
 Material: HSSE 800 (high-speed steel with cobalt)
 Flute/profile: R40
 Tolerance class (internal): 2B
 Intended use: internal thread cutting
How to use
Select an appropriate drill size and prepare the hole according to DIN recommendations for 3/4-10 UNC threads. Secure the workpiece and use proper clamping to avoid movement. Apply a suitable cutting fluid for the work material to reduce friction and heat. Start the tap at low speed, ensuring correct alignment with the hole axis, and advance with steady pressure. For through holes, use continuous forward motion; for blind holes, use a sequence of forward and partial reverse rotations to break chips. Clear chips regularly and inspect the thread profile for conformity to the 2B fit.
Usage recommendations
Use suitable tap holders or collets to minimize runout and avoid excessive radial forces. Match cutting speed and feed to the workpiece material, and monitor tool wear; replace the tap when thread quality degrades. Store the tap in a dry place and protect cutting edges to preserve dimensional accuracy and performance.
