Techniks 04211-06.0 ER11 Collet 6 Mm

Product Description

The TECHNIKS 04211-06.0 is an ER11 series collet sized at 6 mm, designed for use in ER11-compatible collet chucks on CNC machining centers, lathes, and manual milling machines. This collet features through-coolant capability, allowing coolant to flow directly to the cutting tool for improved chip evacuation and thermal control during machining operations. It holds a true indicator reading (TIR) of 0.005 mm, providing the runout precision required for finish milling, drilling, and reaming applications. Machinists and tool crib personnel working in production and job shop environments rely on this type of collet for consistent, repeatable tool holding.

The 04211-06.0 is suited for use in high-speed spindle applications where tight runout tolerances are critical. The 6 mm bore accommodates standard metric shank cutting tools including end mills, drills, and reamers. Through-coolant capability makes it a practical choice for deep-hole drilling and high-feed milling where flood coolant alone is insufficient. This collet is appropriate for both light-duty manual machine work and production CNC environments requiring consistent tool positioning.

Key Features

• ER11 collet series for use with ER11-compatible chucks
• 6 mm bore diameter for standard metric tool shanks
• Through-coolant design directs coolant to the cutting edge
• TIR of 0.005 mm for precise, low-runout tool holding
• Compact ER11 form factor suited for small-spindle and high-speed applications

Compatibility

Designed as a direct-fit replacement for ER11 series collet chucks accepting 6 mm bore collets with through-coolant capability.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the collet chuck and spindle are fully stopped and de-energized before inserting or removing the collet. Clean the collet, nut, and chuck bore of chips and coolant residue before seating to prevent runout error. Torque the collet nut according to the chuck manufacturer specifications for the ER11 series.
