1.
The cutting edge
on the sharpening tool should be inspected frequently to ensure it is
sharp and free from nicks. |
2.
Place sharpening tool
on the baseboard and take care to align the point directly under the bit. |
3.
Turn on the drill motor. |
4. Bring
the handle gently down until a squeal is heard as the sharpening tool
removes tiny black shavings from your drill bit. |
5.
Removing the burr from the cutting edge should be done sparingly by
holding the oil stone flat on the side of the rotating bit and moving it downward on
to the burr. Take care to hold the stone parallel to the side of the bit at all
times. A small amount of burr is good as it helps to make the drill bit
travel through the paper freely. |
6.
Stop the drill motor and check the bit for sharpness. It should be as
sharp as a very sharp knife. If necessary repeat the
above. |
7.
Adjust the drilling depth to just mark the baseboard, do not reset
deep during drilling. Rather, change the position of the
baseboard.
Drilling deeply into the baseboard will dull your drill bit sooner. |
8.
Paraffin or similar lubrication assists the passage of chips and help
prevent overheating of drill bits. Regularly touch the cutting edge and
side of the bit as to apply lubricant to the chips as
they move up through. |
Teflon coated drill bits
do not need lubrication, keep cooler, last longer and are great for
difficult
jobs. |
Mechanical Power Stroke or Hydraulic Operated Paper Drills
|
Remove the drill
bit/bits from your machine. Use a drill press and a small size drill press
vice to hold the sharpening tool, allowing the sharpening tool to centre
it self under the drill bit. Run drill press at 2500rpm or more. See
instructions above. |
Note: A special chuck adaptor
will be needed for non cylindrical fittings. |
