Expertly engineered for high-efficiency thread cutting, the Guhring BSW Yellow Ring Spiral Point Gun Tap range is the definitive industrial choice for high-speed automated machine tapping in through-hole applications. Manufactured to strict DIN 376 dimensional master standards, these premium imperial Whitworth gun taps feature a reduced shank geometry that facilitates deep-hole clearance and prevents mechanical binding. The specialized angular spiral point geometry shears the material cleanly and drives the metal chips forward, shooting them ahead of the tool to completely eliminate chip wrapping. Featuring an advanced high-speed steel substrate with a steam-tempered surface treatment for maximum lubrication retention, Guhring's Yellow Ring series delivers exceptional tool life and chatter-free operation when machining structural steels, mild steel, 250 and 350 grade plates, and unalloyed case-hardened steels.
