  • To clean the collet bore and avoid wrong tool positioning caused by resin build up.
  • Clean means longer tool life and better quality/accuracy.
  • Item X137.004.N includes 4 brushes for spring collets with diameter 1/8'', 1/4'', 3/8'', 1/2'', 3/4'',1''.



Clean collets and tool holders regularly before inserting the cutting tool. Regular cleaning increases the operation safety and ensures great performance. We recommend a regular preventive maintenance of the spindle mouth, collet pocket and spring collets using the right wipers and brushes thanks to our item X137. In order to prevent the formation of corrosion and rust, tool holders and spring collets have to be treated with a protective lubricant before storing them (see our item KleinPROTECT). Any dirt, dust, oil or other contaminant left on the spindle, taper, flange or collet can cause poor TIR (runout) and premature wear. It is necessary to protect your investments in machines with a regular cleaning.
