Seco 75041892 ER32 Collet 10 Mm Bore 40 Mm Oal

Product Description

The SECO 75041892 is an ER32 collet designed for use in ER32-compatible toolholders on CNC machining centers, milling machines, and other rotating spindle equipment. This collet accepts a 10 mm workpiece or cutting tool shank, with a total indicated runout (TIR) of 0.01 mm (0.000394 inches), making it suitable for precision milling, drilling, and reaming operations. The overall assembly length (OAL) is 40 mm, and the outer diameter measures 33 mm. Through-coolant is not supported. Machinists and CNC setup technicians working in job shops, production facilities, and maintenance environments are the primary installers of this collet.

This collet is used in CNC milling, drilling, and general-purpose machining applications requiring a secure, concentric grip on 10 mm shank tooling. It fits standard ER32 collet chucks and toolholders across a wide range of vertical and horizontal machining center platforms. The ER32 series is a common choice for medium-duty cutting applications where tool runout control directly affects surface finish and tool life.

Key Features

• 10 mm bore size accepts standard 10 mm shank cutting tools
• 0.01 mm TIR for precise, concentric tool holding
• 40 mm overall assembly length (OAL)
• 33 mm outer diameter for ER32 collet chuck compatibility
• No through-coolant, suitable for standard dry or flood-coolant setups

Compatibility

Designed for use with ER32-series collet chucks and toolholders. Specific machine model compatibility depends on the toolholder in use; verify ER32 chuck specification before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing collets. Seat the collet into the collet nut before threading the nut onto the toolholder to avoid damage to the collet taper. Inspect the collet bore and toolholder taper for chips or contamination before assembly.
