Available Coating:

•    Teflon - Provides lubrication to the inside and outside of your paper drill. The Teflon reduces friction and heat to increase the wear life of the cutting edge. It also helps the chips flow smoothly, keeping paper sludge from building up and damaging your drill. Recommended for normal paper stock, medium to heavy weight, as well as most coated stocks.

•    Titanium #35 - 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 of 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.
