Model G0846 (Mfd. Since 02/18)
-21-
Here are a few things you can do to ensure easy
operation and better workpiece results:
•
Use the correct bit for the job. Adjust the
chuck rotation so the bit pulls out chips during
the boring operation.
•
When using bits of different profiles and
design, take time to understand what makes
them different and how your process or tech-
nique may have to change.
•
Use bits with a
5
⁄
8
" shank for safe, consistent
results during operation. Bits with smaller-
diameter shanks have an increased risk
of breaking or coming loose during boring
operations, which may result in injury.
•
To use bits with a
3
⁄
4
" shank, use the T28358
Westcott-style chuck (refer to
Accessories
on
Page 26).
•
For longer or deeper mortises, 4-flute bits
are recommended for smaller chip size and
faster chip removal.
Operating Tips
Cutting tools are sharp and
can easily cause laceration
injuries. Always protect
your hands with leather
gloves or shop rags when
handling cutting tools.
Changing Bits
The Westcott-style
5

8
" chuck included with the
Model G0846 is designed to work best with

⁄

"
shank slot mortising bits (see
Figure 15). DO
NOT install or use vertical mortiser chisel bits.
Always ensure the bit is firmly secured in place
before any boring or mortising operation. When
changing bits, follow the instructions below.
Items Needed
Qty
Hex Wrench 6mm.............................................. 1
Leather Gloves ...........................................1 Pair
To change bit:
1. DISCONNECT MACHINE FROM POWER!
2. Put on leather gloves to reduce the chance
of laceration injuries from sharp flute edges
when handling bits.
•
When mortising through hard spots in wood,
use shorter bits with 4-flute design so small
bites can be made and bit is less likely to
grab hard spots as 2-flute bits can do.
•
Avoid deep cuts with bits where spirals
become buried or partially buried in workpiece
and cannot expel shavings. When mortising,
limit cutting depth to
1
⁄
16
" per pass.
•
Never rush a drilling or mortising procedure.
Extra care during setup will ensure satisfac-
tory results.
9. Uses work table feed handle to slowly move
workpiece into bit, bores hole, then moves
workpiece away from bit.
10. Limits depth of each cutting pass to
1
⁄
16
" or
less.
11. Turns machine OFF when operations are
complete.
12. Unclamps and removes workpiece only after
chuck has come to a complete stop.
