Techniks 16302 ER11 Collet Chuck BT30 Taper Shank

Product Description

The TECHNIKS 16302 is an ER11 collet chuck with a BT30 taper shank, designed for use in machining centers and CNC milling applications. It accepts ER11 collets with a capacity range of 1/16 inch minimum to 0.275 inches maximum, providing precise tool holding across a range of small-diameter cutting tools. The chuck features a 70 mm projection and an overall length of 4.66 inches. It does not include through-coolant capability. This chuck is installed by machinists and toolroom technicians in production and job-shop environments.

This collet chuck is suited for vertical and horizontal CNC machining centers equipped with BT30 spindle interfaces. The 70 mm projection makes it appropriate for applications requiring extended reach on small-diameter end mills, drills, and reamers held in the ER11 collet system. It is a standard toolholder used in light-duty precision machining operations where consistent runout and repeatable tool setting are required.

Key Features

• ER11 collet system with capacity from 1/16 inch to 0.275 inches maximum
• BT30 taper shank for use in BT30-compatible machining center spindles
• 70 mm projection for extended reach in confined or deep-cavity setups
• Overall length of 4.66 inches for predictable tool-length offsets
• No through-coolant, simplifying setup in standard dry or flood-coolant environments

Compatibility

Designed as an OEM-style ER11 collet chuck replacement or addition for CNC machining centers with a BT30 spindle interface. Compatible with the full range of standard ER11 collets.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machining center spindle before mounting or removing the toolholder. Use a calibrated BT30 pull stud and torque the retention knob per the machine tool manufacturer specifications. Inspect the taper shank and spindle bore for contamination or damage before seating the chuck.
