THE DEVIL'S IN THE DETAILSWhen you aspire to create one of the most competitive tool holders on the market, the details count. We invest heavily in extensive automation manufacturing and top of the line Mazak and grinding machines while pouring our heart and soul into bringing the tool to life. While not satisfied with just being good, so through customer data and rigorous testing, our R&D team are able to blend over 40 years of manufacturing know-how and real-world feedback to improve the tool holder's design and performance. |

START TO FINISHWe optimize our process for both efficiency and accuracy by utilizing Kawasaki robotic arms to load and unload bar stock into the Mazak multi-tasking machine centers. We use SCM420 alloy steel to lay the foundation and case harden to RC 57-59 with a core of RC 34-39 to provide good core strength and maximize wear life. The core creates a dampening effect which reduces vibration in high speed milling to improve surface finish. The AT3 or better taper accuracy ensures 80% or better taper contact with spindle and using Stotz Air/Electronic Gaging for inspection on the taper. We precision grind the internal bore surface to <.0002" TIR and all bores are ground on a CNC grinder to ensure close run-out tolerance and evenly contact between the collet and the bore pocket. We use Haimer laser balancing machines to deliver a tool that can operate flawlessly at 20000 RPM and Mitutoyo or Mahr indicators to check the run out. |

Mirror FinishedTaper ground to AT3 or better specification ensures 80% or more contact with spindle to reduce harmonics, improve runout tolerance and deliver consistence performance |
Flange ContactPrecision mill finished from multi-tasking Mazak machine on the flange face to eliminate the 1/8" gap between flange and spindle nose to minimize vibration |
Pilot ContactInside bore are precision turned to engage a better contact with retention knob's pilot to increase rigidity |
