ER Tap Collets
 |  |
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—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.

5C Lathe Collets
 |
Round Face |
These collets tightly grip workpieces when installed into a 5C collet chuck or holder. They provide a stronger hold on small workpieces than a standard lathe chuck.

DA Collets
 |  |
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.
