ERG Tap Collet
ERG Tap Collets - Floating Tap Holders for Threading **SPECIAL COLLET - Allows axial float for tapping operations** ERG (ER with "G" for tapping) collets have a floating mechanism that allows the tap to self-feed during threading operations, preventing thread damage. WHY USE ERG TAP COLLETS: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Regular collets hold tap RIGID → Thread pitch errors possible ERG collets allow FLOAT → Tap follows its own pitch perfectly! ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ AVAILABLE SIZES: ┌──────────┬───────────────┬────────────────────────┐ │ ERG Size │ Tap Capacity │ For Thread Sizes │ ├──────────┼───────────────┼────────────────────────┤ │ ER16G │ M3-M10 │ Small taps │ │ ER20G │ M3-M12 │ Common taps │ │ ER25G │ M3-M17 │ Medium taps │ │ ER32G │ M3-M22 │ Large taps (most used) │ │ ER40G │ M3-M27 │ Heavy duty taps │ │ ER50G │ M6-M36 │ Very large taps │ └──────────┴───────────────┴────────────────────────┘ HOW TO USE: 1. Insert ERG collet into ER tool holder 2. Insert tap shank into ERG collet 3. Tighten with ER nut (normal tension) 4. Program tapping cycle - ERG allows float! TAP SQUARE DRIVE: ERG collets have a square drive hole that engages the square on the tap shank. This transmits torque while allowing axial movement.
