Techniks SYIC-32964 is a through-coolant end-mill holder built for CNC milling with an HSK63A spindle. It accepts 1-1/4" end-mill shanks via a 1-1/4" bore and features a 4.25" projection, a nose diameter of about 2.5", and an overall length of approximately 5.51" in steel, with an H5 bore tolerance to help minimize runout. The coolant-through channel supports aggressive milling by delivering coolant directly to the tool shank tip, making it well suited for high-precision operations on machines equipped with HSK63A tooling.
