Parlec DA300-1MM Double Angle Collet DA300 1mm

Product Description

The PARLEC DA300-1MM is a Double Angle collet in the DA300 series, designed for use in DA-style collet chucks on CNC machining centers, milling machines, and other rotating spindle equipment. With a 1mm (0.0394 inch) clamping capacity and a 0.375 inch outer diameter, this collet seats firmly in the chuck to provide consistent tool grip during cutting operations. The overall length measures 1 inch, making it a compact collet suited for close-clearance toolholding applications. Machinists and toolroom technicians install this collet when setting up small-diameter end mills, drills, or other rotary cutting tools that require precise, repeatable concentricity.

The DA300-1MM is intended for use in DA300-series collet chucks found on vertical and horizontal machining centers in production and job shop environments. Its 1mm bore size targets small-tool setups where accurate grip on fine-diameter cutters is critical. This collet is suitable for light to moderate cutting loads typical of finish milling, drilling, and reaming operations with miniature tooling. It is appropriate for both production floor use and toolroom setups where consistent runout and secure tool retention are required.

Key Features

• 1mm (0.0394 inch) clamping capacity for small-diameter cutting tools
• DA300 collet series for compatibility with DA300-style chucks
• 0.375 inch outer diameter for proper seating in the chuck bore
• 1 inch overall length for compact toolholding in tight clearance setups
• Double angle collet design provides secure radial clamping force on tool shanks

Compatibility

Designed as a direct-fit replacement or additional collet for DA300-series collet chuck systems. Specific chuck model compatibility should be verified against the DA300 collet series specification for outer diameter and taper angle conformance.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before installing or changing collets, power down the machine spindle and confirm the spindle has come to a complete stop. Inspect the collet bore, chuck taper bore, and nut threads for chips, burrs, or damage before assembly. Do not exceed the rated clamping capacity of the collet, and torque the collet nut using an appropriate spanner wrench per the chuck manufacturer's specifications.
