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.
Chrome-moly steel collets are more wear-resistant than 52100 alloy steel collets. They hold their shape better over time, which helps them keep a strong grip on taps. They also have lower runout, so your taps last up to 20% longer and create more accurate threads. Often used for high-volume production runs, they hold up to high-speed and high-force tapping in any material.
