The OSG Metric Spiral Flute Threading Tap in M33 x 3.5 is engineered for precise blind-hole threading, delivering reliable performance in professional metalworking environments. Built for machinists who demand consistency, durability, and long tool life across demanding applications.

• Size: M33 x 3.5
• Material: HSS-E (high-speed steel with cobalt) for superior hardness and heat resistance
• Coating: Steam oxide coating to enhance wear resistance and extend tool life
• Flute design: Spiral flutes optimized for efficient chip evacuation in blind-hole operations
• Application: Specifically configured for precise threads in blind holes, with steady depth control
• Brand: OSG, a trusted name in precision threading tools

Designed to deliver consistent, high-quality threads, this tap minimizes heat build-up and wear during deep or demanding cuts. The combination of HSS-E and steam oxide coating provides durability under higher cutting speeds and feeds, while the spiral flute geometry reduces chip packing and re-cutting resistance. This makes it an excellent choice for critical components in automotive, hydraulic, and general engineering projects where accurate thread engagement matters most.
