Important! To prevent the drill from overheating, always avoid drilling too slowly. The drill should be brought
down as rapidly as possible allowing the drills to easily cut through the paper.
Slotted Holes - Instead of punching slotted holes for five and seven hole universal binding work, save time and
cost by drilling a 1/2 inch diameter hole in place of the slot. The slot is only intended to allow the post or ring to be
used in either location, and the large hole permits this.
Plastic Bindings - Drilling holes for plastic bindings, instead of punching them, is practical and saves a great
deal of time, particularly on long run jobs.
Keep Drills Sharp - A dull drill is the major cause of drill breakage and production tie-ups. Usually 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.
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 a 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. On these jobs the coating on the chips
frequently fuse the chips into one solid mass when the drill cools, 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. Be
sure to touch the cutting edge with the lubricant also. Wipe off excess oil before drilling. CARE MUST ALWAYS
BE TAKEN WHEN HANDLING DRILLS.
Keep Spindle Clean - Clean out the drill spindle frequently. This will prevent any buildup in the spindle of the
drill.
