Member of Dormer’s ADX range of high performance drills, the A553 drill with oil feed is capable of producing high quality, accurate holes (to H9 tolerance), even at high speeds and feeds. The A553 has a 130 degree thinned point which helps stop the tool from skipping over the surface of the work piece when you start the hole and also means you don’t need to apply as much force to get the drill to cut the material. The titanium nitride coating improves the life of the drill and also gives better performance when drilling harder materials. The A553 has a specially shaped cutting edge which helps break up the chips from the work piece so they are removed from the hole more quickly and you can drill at faster speeds and feeds. The A553 metric drills are made from premium High Speed steels which means you can use them to drill a wide range of material including stainless steel, steels and aluminium.
