step drill bits
Description
  • SPOGKING Step Drill Bits combine the most desired features of a Step Drill, Speed and control and several customized sizes onto one bit.
  • Ideal for drilling true round holes with precise control in a variety of materials like sheet metal, metal plates, aluminum, fiberglass, plastics, plexiglass, and wood.
  • The permanent laser-etched sizes and targets save time when drilling holes.
  • Two different choices for hex shank provide a firm, positive grip and won’t spin out in the drill.
  • SPOGKING Step Drill Bit is made of high-speed steel for reliable strength. The specially designed cutting edge drills true, round holes for a smooth, clean finish.
  • You can also choose multiple-flutes design that guide the debris out much quicker than a single flute step drill.
  • The groove style can be straight or spiral.
  • The Speed Point tip penetrates fast, eliminates the need for a pilot/starting hole.
