Be sure you have the correct diameter, depth and coating before ordering your Paper Drill Bits. Some Pointers and Tips on Drilling and on How to Increase the Life of Your Paper Drill Bits

Fluted Drill Bits
  • The newest and most advanced technological breakthrough in Drill Bits. Four (4) flutes which are 1/16 inch raised edges inside the Drill Bit rip and tear up the Paper Chads or Slugs passing through the Bit. Fluted Drill Bits work best on harder materials like Chip Board or Card Stock. However, Fluted Bits can also be used on all types of paper stock. At present, Fluted Drill Bits are available for Challenge, Nygren Dahly, and Lawson Paper Drills in 1/4, 5/16, and 3/8 inch diameters..

    MOST PAPER DRILL BIT BREAKAGE AND WARPING IS CAUSED BY OPERATING DULL AND/OR UNSEATED DRILL BITS WHICH RAM INTO THE WOODEN OR PLASTIC BLOCKS OR STRIPS IN THE BASE. BE SURE TO REMOVE ALL CHADS IN YOUR BITS AND SHARPEN YOUR BITS EVERY FOUR (4) TO EIGHT (8) HOURS OR AFTER A SHIFT CHANGE.

    USE A SHARP DRILL BIT AT ALL TIMES.

    Generally, a Drill Bit can be used for approximately four (4) to eight (8) hours of use before it needs to be sharpened. They should be sharpened more frequently when drilling through hard stocks, fiberboard, or abrasive stocks.

    Most Drill Bit breakage is caused because the Bit is dull. To sharpen a Bit apply light pressure. Too much pressure may cause flaring of the tip which renders the Bit unusable. Drill Sharpeners are available and are recommended with purchase along with an extra spare Drill Bit as back up. Sharpening stones are also recommended to debur the outside cutting edge of the Drill Bits for better performance.

    KEEP DRILL BITS CLEAN

    Especially when drilling through perfect bound books and glue. If the inner diameter of the Bit is not cleaned after a shift change or break, glue hardens and the Bit will snap upon the next start up.

    When not in use, Drill Bits can be lightly oiled to prevent rust and corrosion. Use a small toothbrush and solvent to clean the inside of your drill paying particular attention to the drive pin.

    LUBRICATE DRILL BITS OR USE COATED BITS

    Coating allows easier drilling of varnish, laminated and aqueous coated stocks. Applying a lubricating stick such as Drill-Ease every few strokes or a liquid lubricant such as Spin-Eze will allow it Bit to work like a coated Drill Bit.

    DRILL BLOCKS

    Use Drill Blocks to stop the Drill Bit after it penetrates the drilled material so the Drill Tip does not hit the metal base which can cause the Bit to get dull, warp, or break.

    COATINGS FOR SPECIAL JOB TYPES

    TEFLON:
  • Also known as LONG LIFE works great on coated papers and reduces build-up. A special process of baked-on Teflon breaks the barrier of lasting lubricity. It provides lubricity to the inside and outside of Drills Bits.

    This maintains a super tough Teflon coating throughout the life of the Bit regardless of the stock. By reducing friction Teflon increases the wear life of the cutting edge.

    Teflon causes chads to flow more smoothly without binding, making this coating recommended for most normal paper drilling applications. Superior for paper drilling varnish, enamel, aqueous or plastic coated stocks.

    DURALON:
  • A special process that merges space-age alloys with Teflon and breaks the barrier of lasting lubricity. This maintains a super tough Teflon coating throughout the life of the Bit regardless of the stock.

    This friction eliminating coating gives Drill Bits a slick surface inside and outside increasing the war life of the cutting edge and allowing the chads/slugs to flow smoothly without plugging.

    Duralon is recommended for most normal paper drilling applications. Superior for paper drilling varnish, enamel, aqueous or plastic coated stocks. This coating will not wear off even after months of use.

    TITANIUM:
  • This coating increases paper drill life up to 400%. Some users even report that they are self-sharpening.

    This is caused by the abrasiveness of certain papers that will wear out the inner core for the paper drill faster than the outer, diamond-hard skin, creating a self-sharpening razor edge.

    We recommend this paper drill coating for most normal to difficult paper drilling applications. It is especially useful for drilling through plastics and card stock.
