Screw the collet/nut assembly on to the bottom of the spindle. Install the cutter through the bottom of the
collet and tighten the nut on to the spindle by hand to hold the tool in place. Make sure the cutting tool is
both inserted into the collet enough to clamp on to the tool shank, and the cutter extends below the nut
far enough for your application.
WARNING: Cutting tools are VERY sharp. Handle cutting tools with extreme care.
Always use gloves when handling cutting tools to prevent injury!
To secure the tool in the collet, use the spanner wrench and the open end wrench to tighten the nut. The
open end wrench will fit into slots above the threaded portion of the spindle. The spanner wrench has
teeth that fit into slots on the nut. Turn the nut in the direction shown below to tighten the nut. The nut
should be tightened by hand. If the nut is not tight enough, the tool may either slip in the collet, or fall out
during operation.
