Spotting Drills / Centering Drills

For Pre-Drilling Holes on a Wide Variety of Materials

Spotting Drills / Centering Drills

  • These NC Spotting Drills have short flutes and no land or body relief to maintain maximum rigidity.
  • For use in a wide range of materials:  From softer materials such as Aluminum, Brass, Plastic, and Wood to more difficult materials such as Steel, Stainless steel, Composites, Inconel, and Titanium.
  • For softer materials 90° points are typically used to start drills up to 120°.
  • 120° points are used to start drills above 120° (typically 135° drills). This allows the outer cutting edge of the secondary drill to start cutting before the point touches.
  • For tougher and harder materials and for high performance secondary drills the 145° point is recommended. This allows the point of the secondary drill to touch before the outer cutting edge. This helps to reduce chatter and prevent chipping of the secondary drill’s cutting edges.
