Spotting Drills – Centering Drills, Solid Carbide

Spotting Drills / Centering Drills are used for Pre-Drilling Holes on a Wide Variety of Materials

Spotting Drills-Centering Drills for Spot Drilling Holes, Solid Carbide

Solid carbide Spotting Drills-Centering Drills are used to spot drill holes and produce exact hole locations when center drilling holes.

These NC Spot Drills have short flutes and no-land or body relief to maintain maximum rigidity. Maximum rigidity provides the best hole location.

  • Spot drilling prevents drill walking.
  • Spot drill before final drilling to maintain the best hole location.
  • For use on practically any material 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.
  • To Spot Drill / Center Drill tougher and harder materials and for high performance secondary drills the 145° point is recommended.
    • The 145° tools 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.
  • Produced from an Ultra-Fine, Submicron, Nano Grade Solid Carbide.
  • Manufactured in house.
