BSW Yellow Ring Spiral Flute Taps (DIN 371) | Guhring
Expertly engineered for high-efficiency thread cutting in smaller imperial dimensions, the Guhring BSW Yellow Ring Spiral Flute Tap range is built for demanding machine tapping applications. Manufactured to strict DIN 371 master standards, these premium Whitworth tools feature a reinforced shank geometry that delivers exceptional torsional rigidity, drastically reducing the risk of tool breakage during high-torque cutting cycles. The high-performance spiral flute geometry efficiently lifts and evacuates long, stringy metal chips up and out of the workspace, making them the definitive industrial choice for deep blind holes. Featuring a premium high-speed steel substrate with a steam-tempered surface treatment for maximum lubrication retention, Guhring's Yellow Ring series ensures long tool life and clean thread profiles when machining structural steels, mild steel, 250 and 350 grade plate, and unalloyed case-hardened steels.
