Techniks 05620 ER32 Tap Collet 14 Mm Hand Tap

Product Description

The TECHNIKS 05620 is an ER32 tap collet designed to hold hand taps in CNC machining centers and tapping machines. With a 14 mm collet bore and an 11 mm square drive, it secures M18 and M20 hand taps during rigid or floating tapping operations. The ER32 series provides a reliable clamping range suited to production environments where consistent tap alignment is critical. This collet does not include through-coolant capability or tension-compression float, making it a straightforward fixed-drive solution. Installation and tool changes are performed by machinists and toolroom technicians following standard ER collet procedures.

This collet is suited for use in tapping chucks and ER32 collet holders mounted in vertical machining centers, drill presses, and dedicated tapping machines. It is sized specifically for M18 and M20 hand tap shanks with a 14 mm diameter and 11 mm square. Applications include general-purpose production tapping in steel, aluminum, and other common engineering materials where hand-tap geometry is preferred over spiral or forming taps.

Key Features

• ER32 collet series for broad compatibility with standard ER32 toolholders
• 14 mm collet bore accepts M18 and M20 hand tap shanks
• 11 mm square size provides positive rotational drive on tap shank
• Configured for hand tap geometry - no through-coolant passage
• No tension-compression float - fixed rigid drive for consistent tap depth

Compatibility

Designed for use with standard ER32 collet chucks and tapping holders. Sized for M18 and M20 hand taps with a 14 mm shank diameter and 11 mm square drive. Compatible with any toolholder accepting ER32 collets per DIN 6499 standards.

Installation Notes

Installation is performed by machinists or toolroom technicians using a standard ER32 collet nut and spanner wrench. Power down and de-energize the machine spindle before inserting or removing the collet. Seat the collet fully into the nut before threading onto the holder to avoid cross-threading or collet damage. Verify tap shank engagement with the square drive before beginning any tapping cycle.
