321T-3/4-10 is a Champion 3/4-10 spiral point tap, commonly called a gun tap, for heavy duty through-hole tapping. It uses Titanium nitride (TiN)-coated high-speed steel and is supplied as a 3-tap pack.
Key Benefits
- TiN-coated HSS spiral point geometry for heat resistance and heavy-duty through-hole tapping in tough materials
- Spiral point action shears and ejects chips ahead of the tap to reduce chip buildup in through holes.
- Designed for faster, cleaner and more accurate machine tapping than carbon taps.
- For use in the Champion XLT tapper, CNC machines and compatible handheld tap wrenches.
- Made in USA Champion tooling for steel, stainless steel and other tough alloys.
Applications
- Through-hole tapping in steel
- Stainless steel and tough alloys
- CNC and production tapping
- Machine-shop, fabrication and maintenance work

How to Use
Use the correct pre-drill for the 3/4-10 thread, secure the workpiece and keep the tap aligned with the hole. Apply suitable cutting fluid, use the correct tapping speed and feed, and allow the spiral point to eject chips through the hole. Wear eye protection and appropriate personal protective equipment.
Spiral point taps are intended primarily for through holes. Cutting tools may shatter if misused. Follow the machine and tap manufacturer's operating instructions. California Proposition 65 warning may apply.
