ER-Style Collet Holders
ER-Style Collet Holders accept various versions of ER Collets. The holders for Swiss-type
lathes and other CNC lathes are categorized by three styles:
• ER Solid Shank Holder can use the standard ER collet, as well as the ERNC split collets
and the ERQC and ERTC floating tap collets.
• Rigid Tap Holders only use the ERQC and the ERTC floating tap collets.
• Floating Tap Holders use the standard ER collet and the ERTCSP collet that has a
square hole for the tap shank..
The Double-Angle Collet ExtensionTool Holder
mounts directly into a round shank tool holder to
grip small diameter tools securely. Double-angle
collets are used to provide a positive grip on the
tool. Optional Qualifying Collars and Chuck Stops
are available. The Collars can be positioned and
locked on the holder shank to qualify the tool
position in a holder.
Chuck Stops position inside the holder body to provide a qualified locating surface for
tooling and to help prevent tool "push back".
SB and SG Double-Angle Holders
are available for CNC lathe work.
The SB has a 11 ⁄8" shank and the SG has
a 11 ⁄4" shank.

extensions. These holders come with adjustable stops for the drill or round shank tools.
