ER Collets
The most widely used type of collet, these collets hold cutting tools in ER collet chucks for milling, drilling, and routing. Spring slots clamp evenly around the shank to minimize runout for clean, accurate cuts and long tool life. The slots flex to grip slightly undersized shanks too, so you don't need an exact match for each cutting tool in your lineup. You can also use these collets in ER collet fixtures and custom setups to keep small round parts centered.
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 frequently.

ER Coolant Control Collets

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 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.
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.
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.

ER Collet Sets
Collet Set with Wood Stand
Keep a set of ER collets on hand to hold cutting tools for milling, drilling, and routing. They’re the most versatile and widely used type of collet. Spring slots clamp evenly around the shank to minimize runout for clean, accurate cuts and long tool life. The slots flex to grip slightly undersized shanks too, so you don't need an exact match for each cutting tool in your lineup. You can also use these collets in ER collet fixtures and custom setups to keep small round parts centered.
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 frequently.

ER Tap Collets
For Square-Shank Taps
Hold square-shank taps in ER collet chucks and tap holders to create internal threads in workpieces. To hold taps tightly in place, these collets have spring slots that grip the round part of the shank and a square opening in the base that mates with the square end. They meet DIN and ISO dimensional standards.
These collets hold inch and metric taps that have shanks that meet ANSI standards. They will not work with taps that have shanks sized to ISO, DIN, or JIS standards.
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.

Quick-Change Tap Collets
Tap Collet
Tap Collet with Adjustable Clutch
Swap out taps in seconds to limit machine downtime. These collets snap into a holder with just a push. Pull back on the holder’s sleeve to release the collet—no wrenches or collet nuts required. Taps pop in and out just as easily. Press the ring on the collet’s face to replace worn taps. These collets are often used on CNC machines, manual machines, and tapping arms. Also known as Bilz-style tap adapters, they mount to rigid or compensating tap holders that accept tang-drive quick-change collets.
These collets hold inch and metric taps with shanks that meet ANSI standards. They will not work with taps that have shanks sized to ISO, DIN, or JIS standards.
Tap collets work with both rigid and compensating tap holders. Tap collets with adjustable clutch automatically stop spinning when they reach the bottom of the hole to prevent broken taps and damage to workpieces. These collets are great for blind holes and they help break up and clear out chips. They should only be used with compensating tap holders. Remove the retaining ring to adjust the torque limit for a specific tap size or workpiece material.
