Hollow Drill Bit Care
 Refer to the
original equipment manufactures' owners manual, for the
safe operation of you equipment.
To prevent the drill from
overheating,
always avoid drilling too slowly. The drill bit should be passed though the
paper as rapidly as possible while also allowing the drills to easily cut
through the paper.
 Keep Drills Sharp - A dull
drill is the major cause of drill breakage and production tie-ups. Normally,
after three hours of drilling
(depending on the type of paper being processed)
the drill should be sharpened. A dull drill results in poor quality work, and
the need to buy new bits more often.
Keep Drills Clean - A dirty and rusty
drill will not permit the free upward passage of the drill chips. Pressure
built up by a clogged drill will split or break the drill. To keep it free from
dirt or rust, clean the drill of all chips after each use and apply light oil to
the inside and outside. Drills should be cleaned out immediately after each
use. This is particularly true if a coated or varnished stock has been drilled.
When drilling laminates or plastics you should drill a few lifts of plain paper
before shutting down machine, this will clear out the plastic before the bit
cools down. On these jobs the coating on the chips frequently fuse the chips
into one solid mass when the drill cools, making it hard to clean or causing
breakage the next time the drill is used
Lubricate Drills - Lubrication assists
in the passage of the chips and helps avoid overheating of the drills. Use
readily available stick lubricants for this purpose. Hold the end of the stick
against the side of the rotating drill. CARE MUST ALWAYS BE TAKEN WHEN
HANDLING OR LUBRICATING DRILLS.
Keep Spindle Clean - Clean out the
drill spindle frequently. This will prevent any buildup in the spindle of the
drill.
Set the Drills Correctly - Do not cut
too deeply into the cutting block. The drill should just touch the block and
cleanly cut through the bottom sheet. During drilling, do not set the drill
deeper into the block instead change the position of the block frequently.
Drilling deeper into the block dulls the drills quickly. Use a piece of
chipboard underneath your stock. This will make handling the stock easier and
will ensure that the last sheet is cut cleanly through.
Check for Drill Wobble - If spindles
are badly worn or bent through mis-adjustment, have them replaced immediately.
A wobbly or loosely held drill will break.
 Check Your Drill Sharpener - The
cutting edge of the sharpening bit should be inspected frequently to make
certain that it is sharp and free of nicks. Never let a drill drop onto the
sharpening bit. It will chip the sharpening edge (see photo). Use gentle pressure when
sharpening - let the sharpening bit do the work. Check the sharpness of the
drill after sharpening. The cutting edge should be razor sharp.
