Adaptateur de tuyau d'échappement, embout de silencieux auto, connecteur universel en acier inoxydable modifié, réducteur (51-63mm)

Straight Flute Tapes: Thread Size: M12 x 1; Thread Length: 30mm/1.18"; Square End Size: 7mm/0.28"; Cutting Direction: Left Hand. Straight flute design, downward chip removal, clear threads, precision fast threading.MANY USES - Useful for through-hole processing. Used for drilling and tapping stainless steel, aluminum, die cut steel, bronze, hard plastics, etc. Recommended feed speed: general steel: 6-15m/min; hardest steel: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min.Titanium Coating: Titanium coating gives it great corrosion resistance, optimizing wear resistance and hardness, and decreases the friction coefficient. M35 Cobalt high speed steel tool features high hardness (HRC65-66), high red hardness, high wear resistance, good tenacity.Easy to use: used in drilling and tapping machines, CNC and milling machines. Use with thread oil to achieve better quality threads and stronger threads. We advise using machine taps with overload protection male nozzles.Indications: tending to chip or break due to speed overload or non-vertical strike. Use the right threading tools, such as a tapping wrench, a tapping machine. Micro taps (such as M1-M3.5) are mainly used in watches, wood and soft metals with lower hardness.
