R-8 Collets

The Model G0463 features an R-8 spindle taper, which only accepts R-8 collets. R-8 collets come in many sizes, typically ranging from 116" to 78" and 3mm to 20mm. You will need a collet to match the diameter of the shank of the tool you want to hold.

To install the R-8 collet:

1.UNPLUG THE MILL/DRILL!

2.Remove the drawbar cap.

3.Carefully clean the surface of the collet and spindle taper. Ensure that it is free of debris, oil and grease of any kind.

4.Insert the cutting tool into the collet.

5.Insert the collet up into the spindle taper.

6.Slide the collet the rest of the way in until it makes contact with the threads at the end of the drawbar.

7.Using your fingers, thread the drawbar into the collet until the collet draws up into the spindle taper.

8.While supporting the tool in the collet with one hand, tighten the drawbar with the 17mm wrench in your opposite hand.

Note: Do not overtighten the drawbar. Overtightening makes collet removal dif- ficult and causes damage to the drawbar threads, collet, and the spindle taper. Keep in mind the taper keeps the collet and tool in place. The drawbar simply aids in seating the taper.

G0463 Small Mill/Drill

To remove the collet:

1.UNPLUG THE MILL/DRILL!

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 cardboard or hold the cutter or tool with a shop towel to prevent it from falling out of the collet.

4.Using the 17mm 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.
