Paper Drilling Tips

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.
