Grizzly Understanding R-8 Collets for Your Drill and Mill
Page 19

R-8 Collets

If you do not use the drill chuck and arbor, you need to use a collet to insert the cutting tool into the spindle. Your Model G0619 features an R-8 spindle taper, which gives the freedom to use standard R-8 collets. These optional collets come in many sizes, typically ranging from 1⁄16" to 7⁄8" and 3mm to 20mm, and should be matched to your cutting tool shank size.

To install the R-8 collet:

1.DISCONNECT THE MILL/DRILL FROM POWER!

2.Unscrew the drawbar cap.

3.Carefully clean the surface of the collet and spindle taper. Ensure that it is free of debris and is lightly oiled.

4.Insert the cutting tool into the collet, then insert the collet up into the spindle taper.

5.Rotate the collet so it engages the align- ment pin inside of the spindle, then slide the collet upward until it makes contact with the drawbar threads.

6.Thread the drawbar into the collet until the collet draws up into the spindle taper.

7.While supporting the tool in the collet with one hand, snug the drawbar with the drawbar hex wrench in your opposite hand.

Note: Do not overtighten the drawbar. Overtightening makes collet removal difficult and will damage the drawbar threads, collet, and the spindle taper. Keep in mind that the taper keeps the collet and tool in place. The drawbar simply aids in seating the taper.

To remove the collet:

1.DISCONNECT THE MILL/DRILL FROM POWER!

2.Tighten the headstock lock.

LACERATION HAZARD! Leading edges of end mills and other cutting tools can be very sharp. Protect your hands with gloves or a shop towel when handling.

3.Protect the table surface with a piece of card- board or hold the cutter/tool with a shop towel to prevent it from falling out of the collet.

4.Using the drawbar hex wrench, loosen the drawbar but DO NOT remove it.

NOTICE

DO NOT completely unscrew the drawbar before striking it with the hammer. You will damage the threads on the drawbar and the arbor.

5.Using the brass hammer, tap the drawbar to unseat the taper.

6. Unscrew the rest of the drawbar by hand and remove the collet.

Note: When not in use, always remove collets and cutting tools from the spindle taper. Oxidation may cause the collet to seize and make it hard to remove later.
