Parlec DA400-0750 Double Angle Collet 3/4 Inch

Product Description

The PARLEC DA400-0750 is a double angle collet in the DA400 series, designed to securely hold 3/4-inch round shank tooling in compatible collet chucks. With an overall length of 2 inches and an overall diameter of 1.455 inches, this collet provides consistent gripping force and accurate tool positioning for milling, drilling, and tapping operations. It is a precision workholding component used in CNC machining centers and manual milling machines across production shops and tool rooms. Machinists and tooling technicians select this collet when reliable concentricity and repeatable tool holding are required in high-cycle or close-tolerance applications.

The DA400-0750 is suited for use in production machining environments where the DA400 collet chuck system is already in service. It accepts 3/4-inch diameter cutting tools including end mills, drill blanks, and straight-shank drills. The double angle design distributes clamping load across two contact surfaces, reducing tool slippage under cutting load. This collet is appropriate for both light finishing passes and moderate material removal rates in ferrous and non-ferrous machining.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before installing or removing the collet, ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state per facility lockout/tagout procedures. Insert the collet into the chuck body before placing it on the spindle, and tighten the retention nut to the chuck manufacturer's specified procedure using the correct spanner or collet nut wrench. Avoid using pipe wrenches or unapproved tools that can damage the collet nut seating surface.
