Spiral flute taps provide self-cleaning threads as the screw progresses through hard materials in various machining settings due to their three flutes designed with alternating left & right hand threads reducing debris accumulation, improving both surface finish quality and accuracy of threads. Compatible with an UNC-1/4 -20 type designation standard across aviation, automotive industries while providing consistent diameter depth tolerance for strong hole & screw hold; their Modified bottoming action maintains secure grip even against vibrations caused by force or torque changes throughout application use. Made from high-quality cobalt alloys with a molyglide finish adds increased strength, hardness ensuring long life during heavy machining environments common within oil& gas, manufacturing industries who demand consistency in tapping performance even in demanding operations under extreme conditions.
