How to Choose the Right Drill Bit for Anchors
The Golden Rule
For most expansion anchors in concrete:
Drill Diameter = Anchor Diameter (or slightly larger for sleeves)
- Expansion Anchors: Drill hole matches bolt diameter exactly (M10 anchor = 10mm drill).
- Sleeve Anchors: Drill hole is 2mm larger than bolt (M10 sleeve = 12mm drill).
- Wall Plugs: Drill hole matches plug size, not screw size.
