Parlec DA300-5.5MM Double Angle Collet DA300 5.5mm

Product Description

The PARLEC DA300-5.5MM is a double angle collet designed for use in DA300 series collet chucks on milling machines, machining centers, and CNC turning equipment. It accepts tooling with a shank diameter of 5.50 mm (0.2165 inches) and has an overall length of 1 inch and an overall diameter of 0.375 inches. The double angle geometry provides two contact zones for improved gripping force and runout control compared to single angle designs. This collet is a precision workholding component installed by machinists and CNC setup technicians in production and job shop environments.

The DA300-5.5MM is suited for light to medium milling, drilling, and reaming operations where repeatable tool seating is required. The DA300 collet series is a common format found in manual mills and CNC machining centers across general manufacturing, aerospace, and toolroom applications. It is used wherever a DA300 collet chuck is already installed and a 5.50 mm bore size is needed to match the tool shank.

Key Features

• Double angle collet geometry for increased gripping force and reduced runout
• 5.50 mm (0.2165 inch) bore capacity for metric shank tooling
• 1 inch overall length for compact toolholder stack height
• 0.375 inch overall diameter fits standard DA300 series collet chucks
• DA300 collet series for broad compatibility across DA300 chuck bodies

Compatibility

Designed as an OEM-style replacement or direct-fit collet for DA300 series collet chucks requiring a 5.50 mm bore capacity.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle and chuck are fully de-energized and the machine is locked out before changing collets. Inspect the collet bore, taper surfaces, and chuck body for chips or contamination before seating the collet. Do not exceed the rated clamping torque specified by the collet chuck manufacturer for this bore size.
