Keep
Paper Drill Bits Sharp
|
|
|
|
The primary cause of paper drill breakage and poor work quality is a dull bit. For best results,
paper drill bit. For best results, paper drill bits should be sharpened after every 4 to 8 hours of use. They should be sharpened even more often when
paper drilling
through hard stocks, fireboard or abrasive stocks.

Keep
Paper Drill bits Clean |

Another cause of broken bits is a clogged bit. This is commonly cause when paper drilling through perfect bound books and glue. If the inner diameter of the bit is not cleaned out after shift change or break, glue hardens and the bit will snap upon next
start up. Clean out bits after each use. When not in use, paper drill bits can be lights oiled to prevent rust and corrosion.

Lubricate
Paper Drills or use Coated Paper Drills |
|
|
|
|
DHP specializes in coated paper drills, See here for information on Titanium #35, Teflon and
Duralon. Coating allow easier paper drilling of vanish, laminated and aqueous coated stocks. Also available is the #7604 Lubricating stick
which can be applied to the paper drill bit every few strokes and works like a coated
paper drill bit. |

Suggestions for speed & Feed |
Increase the RPM of
the paper drill bit when paper drilling smaller diameters (1/8" or3/16"). As you
increase the diameter of the bit, decrease the RPM accordingly
(i.e., 1/2" bits should be run much slower than 1/8" bits).
The feed (or strokes per minute) should be adjusted depending on the
type of stock being paper drilled. Generally, the softer the stock being
paper drilled, the slower the feed. A good starting point for 1/4' bit
paper drilling through 2" of 10 lb. stock is 2000-2500 RPM at strokes per
minute.
Remember that a paper drill must cut/drill the paper ,not punch it
like a hammer. Give the bit time to drill the paper. The paper drill
should never turn purple from overheating. |
