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, Premium 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.
