dissipation of heat from the tip of the drill bit, which prolongs the drill's life. Removing the drill and evacuating the chips after drilling short distances, often called "step-drilling," will also lessen the chance of heat build-up. Some good rules of thumb when deep-hole drilling are to reduce your rate of speed and feed, remove the bit more often from the material, and use lubricant ...
