All Step Drill Bits have Split Points and come in two different materials.
· The Split Point reduces “Walking” which is the tendency of a spinning bit to rotate away from the point at which you want to drill.
· Because CBN(cubical boron nitride)is a much harder abrasive than even silicon carbide or corundum, a better an sharper cutting edge is
achieved without burrs.
· Because of this higher dimensional precision,the drill bits will last considerably longer while maintaining precise process tolerances.
· The High Speed Steel(HSS) allows the bit to cut faster than High Carbon Steel. At room temperature,HSS and high carbon steel have an
equivalent hardness;at elevated temperatures HSS become advantageous.
· Reduces set up time
· No more CBN-ground flutes without burrs mean a superior cutting edge an longer tool life.
· Each step has a radially adjusted relief produced by CBN grinding,relating directly to the diameter of the step, so the cutting edge is always the highest point of the diameter
· Each step is axially CBN relief-ground, meaning the cutting edge is also the highest point of the axial cutting axis
· The cutting edge of each step has relief angle,meaning the cutting edge is also the highest point in advance direction
