DRILL HEAD AND BIT TIPS
1. KEEP DRILLS SHARPENED
A dull drill bit can be a major cause of drill bit breakage. Sharp-
ening and cleanliness help prolong bit life. Imperfections in
drilling indicate dull drills. A dirty drill bit will clog and will
cause pressure build up that can split or break the drill bit.
Clean the drill bits of all chips after each use and apply a light
film of oil to the inside and outside. When drilling coated stock,
the chips frequently are compacted into slugs inside the drill
bit, it is important that the drills be cleaned out immediately
before the drill cools or the slugs will become a solid mass that
will cause the drills to break the next time they are used.
2. LUBRICATE DRILLS
Use the drill lubricant sticks that are provided with your drill to
assure better chip passage and to avoid overheating of the
drills. Touch the side of the drill bit near the cutting edge with
the end of the lubricant stick. Try to coat the inside of the bit as
well. Squeaking, slight burning or smoking is a common sign
that lubrication is needed.
3. SET THE DRILLS CORRECTLY
Do not cut too deeply into the wood blocks. The drills should
just touch the block enough to make an impression and cleanly
drill through the bottom sheet. Do not set the drills deeper into
the blocks after drilling, move the blocks or flip them over or
turn them end for end to get a new cutting surface. The use of
chipboard (cardboard) below the lift when drilling can some-
times improve the hole quality.
4. CHECK BELTS
Loose belts can slip and cause overheating of drills. Tighten if
necessary, but be careful not to over tighten.
5. CHECK FOR RUNOUT OR WOBBLE
Drill head spindles that are worn or bent as a result of mis-
adjustment can cause drill breakage. Have the spindles
replaced immediately.
6. INSPECT DRILL SHARPENER
Check the cutting edges of the carbide cutting tool for nicks
and sharpness. Don’t let the drill drop on the cutting tool or the
cutting edge will be damaged on the tool. Use gentle pressure
when sharpening. Too much pressure will spread the mouth of
the drill, causing breakage. only a few turns will sharpen the
drill.
7. USE DRILL EXTENSIONS
Drill extensions help chips flow up into the spindle and out of
the ejection slot. There are two sizes of extensions: the black
extension fits 1/8" through 5/32" drills; the gray extensions fit
3/16”, 7/32”, and 1/4" drills. The larger diameter drills do not
need extensions. Extensions help prevent drill breakage, espe-
cially when drilling coated stock.
8. REMOVE DRILLS FROM HEADS WHEN FINISHED
Depending upon atmospheric conditions, if the drills are left in
the spindles overnight or for the weekend, they may rust. If this
occurs, they will be extremely difficult to remove.
9. LUBRICATE HEADS
A) Drill heads should be greased approximately once every
five working days with Lubriplate #1200-2 General Purpose
Grease or equivalent. Use only two squeezes of a small grease
gun. The grease zerk for the drill heads is located on the rear of
the head. To grease the heads, drop the waste chute out of the
way by removing the shoulder screw on the right side of the
support rail casting and slide the waste chute off of the roll pin
on the left side.
B) Put three to four drops of light oil in the top of each drill
head spindle once every four working hours, and once every
time before the drill is started. Use Marvel No. 005 Lubricat-
ing
oil or equivalent.
