Note: For cutting steel pipe and tubing, we

recommend bi-metal hole saws. These can
be operated at up to 500 RPM for most
diameters and should be operated at higher
speeds for thin wall tubing.

Note: We recommend that height of spindle

support be adjusted so hole saw is as close
as possible to workpiece without touching.
This will help minimize flex in notcher.

Drill Press Operations

To use the Model T28929 with a drill press, the
notcher must be clamped securely to the drill
press base. It is important that the notcher is
secure enough so it will not twist or come off
of the table during use. To ensure square cuts,
the jig must be square to the base before being
mounted to the drill press table.

To reduce risk of eye or face injury from
flying chips, always wear approved safety
glasses and a face shield when operating
drill press.

Cleaning & Protecting

Cleaning the Model T28929 is relatively easy.
Periodically brush away cuttings and debris,
especially around the spindle and bushings to
avoid scoring and binding.

Protect the notcher by wiping it clean after
every use and applying a light lubrication (see
Lubrication) to moving parts.

Before moving or storing tool, insert lock pin into
spindle to prevent movement. Store notcher cov­ered in a dry, dust free location.

Lubrication

During operation, the spindle bushings will require
lubrication. A few drops right before operation
will usually be adequate, but when using notcher
for long periods at a time, lubrication should be
applied several times per hour.

Failure to align spindle flats properly with
chuck jaws may result in spindle coming
loose and damaging notcher and drill chuck.

5. Remove lock pin from spindle then rotate

drill chuck by hand to test how easily whole
assembly turns.

— If assembly turns with minimal effort, pro-

ceed to Step 6.

If assembly does not turn with minimal

—

effort, adjust angle of drill until it does,
then proceed to Step 6.

With lock pin removed, apply cutting fluid,

6.

turn drill ON, and perform notching operation.
