    Angled Ports

    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.
    Sealed Coolant Delivery Collet—Sealed collets run coolant through the cutting tool, so they only work with tools that have coolant holes. Since the coolant runs through the tool, they’re a better choice for deep-hole drilling and high-speed machining than collets with angled ports. Steel seals are built into their body, so they withstand higher pressure and last longer than collets with rubber seals.
    Angled Ports Coolant Delivery Collet—Collets with angled ports direct coolant around, not through, the tool, so you get the benefit of coolant control without needing expensive tools with coolant holes.
    52100 Alloy Steel—Hardened 52100 alloy steel collets are made from the same tough material used to make bearings. They’re more wear-resistant than basic spring steel collets but will wear faster than hardened chrome-moly steel collets if you change bits too frequently.
    Chrome-Moly Steel—Hardened chrome-moly steel collets are more wear-resistant than hardened 52100 alloy steel collets. They hold their shape better over time and have lower runout, even with frequent bit changes. Often used for high-volume production runs, they stand up to high-speed, high-force machining in any material. Their maximum coolant pressure is higher than 52100 alloy steel collets, so they’re a better choice for deep-hole drilling and turning operations in CNC Swiss lathes.
