Radial runout vs toolholding systemWhen high speed milling, the radial runout of the tool has a big influenceon the results. When the radial runout of the endmill is to large, the tool willget unbalanced and will start vibrating. Resulting in: shorter toollife due tounequal edge wear, bad surface finish and the risk of breaking the tool.The shrink holder, is the most accurate system and therefore recommendedby our application engineers.0,025 0,010 0,003 0,003Weldon/WhistlenotchCollet chuckHydrolic holderAdvantages shrinking system- Shrinking gives a 2-3 times higher clamping forcethan the collet and hydrolic holder.- Higher rigidity.- Balanced design, no obstacles around the endmill.Shrink holder27
