Techniks 17130-3/4 End Mill Holder BT30 3/4 Inch Bore

Product Description

The TECHNIKS 17130-3/4 is a BT30 taper shank end mill holder designed for securing end mills in CNC machining centers that use the BT30 spindle interface. It accepts a 3/4-inch bore end mill and provides 2.36 inches of projection from the spindle face, giving machinists adequate clearance for most standard milling operations. The 1.75-inch nose diameter provides a solid clamping surface, and the overall tool length of 4.266 inches suits typical BT30 machine envelopes. This holder is intended for use by CNC machinists and toolroom professionals working with BT30-equipped vertical or horizontal machining centers.

This end mill holder fits BT30 spindle tooling applications in job shops, production machining environments, and toolrooms running compact CNC machining centers. The 3/4-inch bore accommodates standard 3/4-inch shank end mills. The 2.36-inch projection suits general-purpose face milling, slotting, and peripheral milling operations where moderate reach is required. No through-coolant is provided, making it best suited for applications where coolant is delivered externally or flood-style rather than through the spindle.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machining center spindle before inserting or removing toolholders. Use the appropriate BT30 pull stud and torque the drawbar or ATC mechanism per the machine manufacturer specifications. Inspect the taper bore and holder taper surface for contamination or wear before seating to ensure proper runout performance.
