Chip Characteristics

If chips produced by your operation are blue and burnt and overheated, but the cutting speed is correct, reduce the feed rate until the chips are silver.

If the chips are powdery, increase the feed rate so the chips are more coarse but not overheated.

4.Align the keyway of the tool (collet with cutter, face mill, or drill chuck with taper shank) with the protruding set screw inside the spindle, and push the tool firmly into the spindle taper to seat it.

5.While holding the tool in place with one hand, thread the drawbar into the tool until it is snug.

Note: Make sure the drawbar is threaded into the tool a minimum of five to 10 turns.

6.To fully seat the tool into the spindle, tighten the drawbar with a 19mm wrench.

Note: Over-tightening the drawbar could make removing the tool difficult, so only snug the drawbar in place.

7.Re-install the drawbar cap.

2.While wearing gloves, keep one hand on the tool, loosen the drawbar with the 19mm wrench, then completely unthread it.

—If the tool does not release from the spindle taper when the drawbar is unthreaded, turn the drawbar back into the tool five to ten threads, then tap the top of the drawbar with a dead-blow hammer or block of wood until the tool releases.
