✔ Includes protective case to prevent nicks and damage  

Engineered for vertical-style mills, this tool ensures precise spindle squareness, reducing setup time and preventing tool wear caused by improper head alignment.

Hardened 52100 Steel

Used by machinists to simplify mill setup and improve consistency.

Constructed from high-carbon 52100 chromium steel and hardened to 60-62 HRC for maximum durability in harsh machine shop environments and toolrooms.

Reduced Needle Jump

1. Mount indicator 
2. Sweep across the Tramming Ring surface  
3. Adjust your mill head based on readings  

Our precision-ground surface isolates spindle rotation from ambient toolroom vibration, virtually eliminating indicator oscillation for sub-thousandth alignment accuracy.
