Attaching MILWAUKEE STEEL HAWG™ CUTTERS
See the information supplied with your arbor.
Cutting Procedure
1. Refer to the chart supplied with the arbor to determine the proper drill
rotating speed for the type of material and cutter diameter. When
using this chart, use the upper end of the range for softer materials
and the lower end for harder materials. Set the drill rotating speed to
the recommended speed.
2. Position the workpiece or tool so that the center pin is directly over
the desired drilling location.
3. The use of HAWG WASH™ cutting fluid is required for long life of
these cutters (see "Lubrication"). Attach the hose to the oil fitting on
the side of the arbor and to your lubricant reservoir.
4. Swing the arbor arm in the direction of the spindle rotation until it
comes in contact with the side of the drill motor or drill press.
5. Start the drill motor.
6. Cutting fluid will not flow freely until the center pin is depressed
slightly. Move the cutter towards the material until the center pin is
depressed slightly and begin pumping cutting fluid.
7. When feeding the cutter into the material, use only enough pressure
to produce efficient cutting without overloading the tool or cutter.
Because STEEL HAWG™ CUTTERS have multiple cutting edges,
they require considerably less downward pressure than ordinary
twist drills. STEEL HAWG™ CUTTERS work best at their recom-
mended drill rotating speed and with moderate pressure. Excessive
pressure will only slow the operation and damage the cutter. Use
less feed pressure when slotting or notching because there is less
support for the cutting edges in these situations.
8. Avoid raising the cutter before the cut is complete. Keep constant
pressure throughout the entire operation to prevent chips and cut-
tings from falling under the cutting edges. A loose cutting under the
cutter can make cutting difficult or impossible.
9. When the cut is completed, stop pumping cutting fluid, and withdraw
the cutter while the drill motor is still rotating.
10. Turn the drill motor off.
11. When the drill has stopped, use a pliers to remove cuttings from the
bit and arbor. Use care to avoid damaging the carbide teeth.
12. The center pin is spring loaded and should eject the slug when the
cut is completed. Provide protection from falling slugs for people or
property below.
Lubrication
A continuous flow of lubricant is required with these cutters.
MILWAUKEE HAWG WASH™ (cutting fluid) is recommended for most
applications. It is available in a case of twelve 16 oz. bottles of concen-
trate, Cat. No. 49-32-0081, which will make 1 gal. of lubricant per bottle.
Failure to use the lubricant properly will cause cutter damage. When cut-
ting with STEEL HAWG™ CUTTERS, supply a continuous flow of cutting
fluid to the arbor. When notching or slotting, the lubricant system may not
supply enough lubricant to the cutting area. In these situations, the cut-
ting fluid should be applied directly to the area being cut. Alternative
lubricants introduce different cooling and lubricating reactions. The op-
erator is responsible for the application of lubricants other than HAWG
WASH™ cutting fluid.

Using MILWAUKEE STEEL HAWG™ CUTTERS
MILWAUKEE STEEL HAWG™ CUTTERS cut an annular ring around the
edge of the hole leaving the center “slug” intact. This greatly reduces the
time, power and drilling force required. The carbide teeth also leave a
finished hole that does not require reaming. These cutters are designed
for use with an electromagnetic or industrial drill press.
•
Do not use these cutters in hand held tools.
• Center pin is spring loaded. Provide protection from ejected slug for
people and property below drilling area.
• Do not remove cutter from arbor unless slug is removed. Slug may
be ejected unexpectedly.
• Keep pump bottle and hose away from moving parts.
• Use pliers to remove chips from bit and arbor only after motor has
stopped.
• Avoid contact with the carbide tips.
• Periodically inspect the carbide tips for loose or cracked tips. DO
NOT USE carbide tips with cracked or loose tips.
• These bits require the use of HAWG WASH™ cutting fluid
for extended life. Do not use cutting fluid in an overhead or
any other position that allows cutting fluid to enter motor
or switch enclosure.
• Wet connections are shock hazards. Prevent cutting fluid
from traveling along cord and contacting the outlet, exten-
sion cord connections or tool plug. Each time tool is
plugged in, elevate extension cord or gang box connec-
tions and arrange a drip loop (See Fig. 12). If plug or
connections get wet, turn power off to outlet before
unplugging tool.
WARNING!
Always use well maintained equipment with minimum
spindle run out.
