Uxcell 3/8-24 UNF Spiral Flute Thread Tap – M2 HSS, Nitrided Coated, 2B Tolerance, For Blind Holes & Stainless Steel

About This Product

This uxcell spiral flute tap is built for clean, accurate threading in tough materials.

The thread size is 3/8-24 UNF with a 2B tolerance, and the overall length is 75mm (about 2.

95 inches) with a thread length of 32mm.
Made from M2 high-speed steel (HSS6542) with a nitrided coating, it's hard, tough, and wear-resistant – so it stays sharp through repeated use.

The spiral flute design is the real star here: it helps guide the tap into the hole smoothly, reduces the torque you need, and clears chips out efficiently, which is crucial for blind holes or deep threading.

This tap handles stainless steel, aluminum, cast iron, alloy steel, regular steel, non-ferrous metals, and even hard plastics like a champ.
Best used on drilling machines, tapping machines, CNC equipment, or milling machines – and it really shines when you pair it with tapping oil for better threads and longer tap life.
One heads-up: this is meant for machine use with overload protection, not for hand-tapping or electric drills.
Keep it vertical (90 degrees) and slow down on harder materials.

Precise, durable, and professional-grade.
