Techniks 04225-10 ER25 Collet 10mm Through Coolant

Product Description

The TECHNIKS 04225-10 is an ER25 series collet designed for precision tool holding in CNC machining centers, milling machines, and drilling applications. Sized at 10mm, it delivers a total indicated runout (TIR) of 0.000200 inches (0.0050mm), making it suitable for applications that demand close tolerances and repeatable tool positioning. The collet features through-coolant capability, allowing coolant to flow directly to the cutting zone for improved chip evacuation and tool life. Machinists and CNC operators install this collet into compatible ER25 collet chucks as part of standard tooling setups.

This ER25 collet is used in production and job-shop environments where consistent tool runout and coolant delivery are priorities. It fits residential shop, commercial, and industrial machine tool applications. The 10mm bore size accommodates shanked cutting tools within its clamping range. Through-coolant support makes it well suited for deep-hole drilling, high-speed milling, and other operations where heat and chip buildup are concerns.

Key Features

• ER25 collet series for broad chuck compatibility
• 10mm collet size for precise tool shank clamping
• TIR of 0.000200 inches (0.0050mm) for high-accuracy tool holding
• Through-coolant design channels fluid directly to the cutting edge
• Compact and lightweight at 0.5 pounds

Compatibility

Designed as an OEM-style replacement or standard tooling component for ER25 collet chucks used in CNC milling, drilling, and machining center applications.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be powered down and brought to a full stop before changing collets. Use a proper ER25 collet nut and spanner wrench to seat and torque the assembly according to the chuck manufacturer's specifications. Inspect the collet bore and chuck taper for debris or damage before installation to maintain TIR performance.
