Pioneer Drill Bit 1/2" CHT

Drill Bit Types

Steel: Uncoated steel drill bits will cover a majority of basic drilling applications - normal paper stock, light to medium weight.

CHT (Teflon): Teflon coated to prevent build-up and increase drill bit life by reducing heat. Works great for medium to heavy weight and coated stocks.

Drilling Tips

Keep Drills Sharp: Sharpen drills every 4 to 8 hours of use - even more when drilling through hard or abrasive stock. Most breakages occur as a result of dull drills.

Keep Drills Clean: This is especially true when drilling perfect bound books and glue. If the inside of a drill is not cleaned, glue will harden and snap a drill bit upon next use. Use a small brush with solvent to clean the inside of the drill bit. Bits can also be lightly oiled to reduce rust or corrosion when not in use.

Keep Drills Lubricated: Some bits are coated (i.e., Teflon), which will provide lubrication. Consider using a lubricating stick to reduce heat and clogging.
