Techniks 17846B Tool Holder Tightening Fixture BT40 CAT40

Product Description

The TECHNIKS 17846B is a tool holder tightening fixture designed to secure and stabilize tool holders during assembly and disassembly of cutting tools in CNC machining environments. Standing 6.25 inches tall with a 3.75-inch head diameter and a base length of 3.1875 inches, this fixture provides a stable platform that prevents tool holders from rotating while technicians torque collet nuts or end mill holders to spec. It weighs 10 pounds, giving it the mass needed to stay planted on a bench without clamping. Machinists, toolroom technicians, and CNC setup personnel are the primary users of this fixture.

This fixture is suited for toolroom benches and CNC setup stations in both job shop and production machining environments. It accepts multiple taper standards in a single unit, making it practical in shops running mixed spindle inventories. Compatible taper types include BT40, C6, CAT40, HSK63A, HSK63E, HSK63F, and ISO40, covering the most common 40-taper and HSK63 tool holders used in vertical and horizontal machining centers. A single-position design keeps the workflow straightforward during tool changes and presetter loading.

Installation Notes

Place the fixture on a clean, flat workbench surface before loading a tool holder. Always ensure the spindle taper and fixture socket are free of chips and debris prior to seating the holder. Use a calibrated torque wrench when tightening collet nuts to manufacturer specifications. Do not use the fixture as a vise or for any purpose other than tool holder assembly and disassembly.
