Robust Tool Handle & Collet System

Robust designed the collet system around popular ER series collets.

The Collet Handle System gives turners a way to quickly and confidently change tools utilizing the same handle. With 4 different collet sizes included with each handle size you can easily swap out tools with a twist of your wrist.

But it’s not just tool changing that is important, simply removing the tool for grinding greatly facilitates the use of grinding jigs.  That’s accomplished quick and easy.

Collets: Each system comes equipped with four collets that fit common size round gouge and chisel shafts.  Each collet has a useful range of a little over 1/32”, or about 1mm.   These collets are standard industrial grade collets. Robust stocks the sizes listed below.  Other sizes are readily available from a variety of industrial sources such as www.use-enco.com and www.mscdirect.com.

Handles: The handles are Ash.  The overall length for the ER32 is 20.5″ and for the ER25, 16″

NOTES: If the tool spins in the collet during heavy cuts, try tightening up the collet nut with a gloved hand.

Lightly oil the threads on the collet nut and stem for smooth operation.

Warranty
Metal parts: 5 years.  Wooden handle: 30 days.  Please note: Wood is a natural material and while we inspect each piece visually for flaws and defects we cannot prevent breakage.  If you break the wooden part of the handle after the 30 day warranty period, you can return it for replacement for a modest fee.
