Product Description

Using the Lever Collet Closer

Collet Closer InstalledAnyone doing repetitive lathe operations on small parts will find this new accessory saves a lot of time when holding parts into a WW collet. Instead of loosening and retightening the drawbar each time a part is inserted, with this closer you make that adjustment just one time. After that, the collet is released and retightened simply by pushing a lever back and forth. Moving the lever to the right releases the part from the collet, a new part is inserted and the lever is moved back to the left to lock the part in the collet. Hardened steel components assure long life.

Long stock up to 3/16″ in diameter can be held through the WW collets and spindle. Larger parts up to 5/16″ or 8mm can be held in the face of the collet, and collet pot chucks are available for even larger parts up to 1″ diameter.

Easy Installation

  • Easy to install—just tap one existing 4-40 hole in spindle if not already tapped for threading attachment (self-tapping screw included)
  • Wear parts are made from A2 hardened steel, yoke is made from 1018 steel and ball carrier and other parts are made from brass and 12L14 steel
  • Long stock up to 3/16″ diameter can be passed all the way through the spindle and collet
  • Larger parts can be held with WW collets up to 8mm (3/8″) or in a custom machined WW pot chuck
  • Includes 3/8″ knockout bar plus special #1 Morse to WW collet adapter with pin to engage keyway in collet to prevent rotation
  • As usual, installation and operation are covered in the thorough, illustrated instructions that come with it

Troubleshooting Interference between the LCC and the Plastic Belt Guard

Dashed lines indicate plastic belt guard cut-outs.

You might find possible interference issues between the LCC and the plastic belt guard. If the belt guard interferes with the pin on the LCC yoke make a small cut-out in the guard (see image for reference). This can be done with an X-acto® knife or Dremel® Tool. Please note that if you have a DRO Tac Sensor it will not work with the LCC. Click the “Instructions” tab to download a PDF version of the instructions.

See Cary Millsap’s Tip #75 on how to install a removable tach sensor.
