Made with high-performance machining in mind—these collets not only grip your cutting tool but also direct coolant to the tool's cutting edge. They have coolant channels designed to work with through-spindle coolant (TSC) systems to clear chips and reduce heat from friction, resulting in clean cuts and long tool life. Place them directly into your ER collet holder, no need to fuss with special collet nuts, coolant rings, or repositioning hoses and nozzles with every setup change.

You get the benefits of using an ER collet, too. Spring slots clamp evenly around the shank to minimize runout for accurate cuts. Keep in mind, these collets must form a tight seal around the tool shank for proper coolant delivery, so match the shank size to the collet size exactly for the best results.

When installed into a 3J collet chuck or holder, these collets securely grip round workpieces. They provide a stronger hold on small workpieces than a standard lathe chuck. All have external threads.

Insert into a 16C collet chuck or holder to tightly grip round workpieces. They provide a stronger hold on small workpieces than a standard lathe chuck. These collets have both external and internal threads.

Also known as double-angle and Erickson collets, these collets are used for drilling, reaming, and light milling. They grip cutting tools in DA collet chucks but are less accurate and have a weaker grip than ER and TG collets. This can lead to a shorter life for these collets and cutting tools. You can also use them with die grinders to hold bits and burs.

Clamp cutting tools in TG collet chucks for rough milling and drilling. These collets have a steep taper angle for a tighter, more stable grip than ER collets. This design gives them the strength to handle large tools and aggressive cuts. However, their grip range is smaller than ER collets, so you’ll need more collets to hold the same range of shank sizes. Use them in CNC machines and drill presses.
