DA Collet Nuts
Secure collets inside DA collet chucks, also known as double angle collet chucks. Tightening the nut squeezes the collet around the cutting tool, clamping it firmly in place.
CAT Taper Collet Chucks
Hold collets tightly in CNC machines with CAT taper spindles for milling, drilling, and routing. Made from high-grade hardened steel, these chucks remain rigid and accurate while resisting wear—even at high speeds. The shank on these chucks is precision ground to the industry standard AT3 tolerance—or better—for a secure fit that minimizes runout in your machine spindle. To ensure compatibility across machines, these chucks meet ANSI/ASME standards for CAT spindles. Insert your collet and tighten the nut to clamp your tool in place. Internal threads on the shank let you attach a retention knob, so you can connect these chucks to your machine’s drawbar system.
All chucks can deliver coolant to your tool’s cutting edge to clear chips and extend tool life. If you have a machine that sends coolant through the spindle, pair them with an ER coolant control collet for the best results.
To maximize grip and minimize runout, choose a chuck where your tool diameter falls in the middle of the bit shank size range.
Chucks balanced to G 6.3 are a cost-effective option that is good for most machining tasks.
Chucks with a collet stop screw set the tool depth in the chuck for consistent, repeatable performance when you change tools.
Chucks with an RFID chip hole hold a small RFID tag for automatic tool identification and tracking.

Straight-Shank Collet Chucks
Extend your tool holder’s reach or adapt it to fit different collet systems on manual and CNC lathes and machining centers. Made from hardened alloy steel, these chucks remain rigid and accurate while resisting wear—even at high speeds. Their shank is also precision ground for a secure fit that minimizes runout in your machine spindle. Insert your collet and tighten the nut to clamp your tool in place.
These chucks have a collet stop screw that sets the tool depth in the chuck for consistent, repeatable performance when you change tools. They’re also through-bore coolant-compatible, so they can route coolant through their center to clear chips, improve the finish of your workpiece, and extend the life of your tool. If you have a machine that sends coolant through the spindle, pair them with an ER coolant control collet for the best results.
To maximize grip and minimize runout, choose a chuck where your tool diameter falls in the middle of the bit shank size range.
