GTI / GTIN - Tapping Attachment

GTIN ER32 – Tapping Collet
Compact tapping collet with tension and compression
floating mechanism for ER32 collet chucks
A tapping collet for standard and rigid tapping operations. apping & Reaming Devices
The GTIN ER32 collet makes tap removal and
replacement easy, quick and reliable. Designed
for stationary and rotating applications, the
GTIN ER32 collets are economical and efficient
due to the ability to use existing ER32 collet
chucks (with various shank sizes and types).

Applications
The GTIN ER32 tapping collet is designed especially for
CNC mill/turn centers, for regular and rigid tapping.

Advantages Description
• Quick tap change by a front clamping nut Short tap chucks for ER collets.
• Compact design for minimal clearance
between the turret and chuck
• Fits every type of stationary and rotating ER32 collet chuck Applications
• Positive tap drive with internal square driver Axial float/tension/compression type for CNC milling
machines and lathes with reversing motors and
• Compensates for machine feed and tap pitch
variance, resulting in greater thread accuracy rigid tapping.
• Floating mechanism compensates for Features
misalignment between tap and workpiece
• High accuracy due to tension and • Compensates for machine feed and tap pitch variance
compression mechanism • Floating mechanism compensates for
• Available for all tap shank standards misalignment between tap and workpiece
(DIN, ISO, ANSI, JIS) • Right- and left-hand tapping
• Tapping range M1-M16 (#0 to 5/8”)
• Saves setup time by quick tap changing Advantages
without removing GTIN from the machine • Practical and efficient tap holding by the ER
• Optimal for machines which have limited spring collet without using jaw drive
space between turret and workpiece • Compact design for minimal clearance applications
• Heavy duty design for high torque drive ensures
the same accuracy as the tap itself

1 Enter feed rate according to thread
pitch (or 1-2 % lower). Set spindle to
starting point with 0.08 clearance.
2 Start spindle forward with right hand
rotation until reaching desired depth.
3 Stop feed and rotation and reverse to starting point.
