Uncompromised Quality Engineered into every SPIN-TRU Holder
- HIGHER METAL REMOVAL RATES
- IMPROVED SURFACE FINISHES
- INCREASED BEARING LIFE
- INCREASED ACCURACY
- GREATER REPEATABILITY
- LESS CHATTER
Toolholders make the all important connection between the cutting tool and the spindle. 
With the hard earned money that you invest in cutting tools,
it only makes sense to do everything possible to increase tool life. One of the best, easiest and least expensive ways to do this is to use SPIN-TRU BALANCED TOOLHOLDERS.
AT3 Class Accuracy results in various advantages during machining, such as:
- Greater contact area with machine spindle, resulting in longer spindle bearing life
- Less vibration and chatter during milling
- Longer cutting tool life
- Improved runout accuracy and surface finish
- Higher metal removal rate
- Enhanced safety
