What the AI looks for in Forstner Drill Bits
- Rim type
- Continuous rim for clean edges; sawtooth rim for large sizes and faster cutting The rim trades finish quality against speed and heat.
- Use in a drill press
- Use a drill press or guide, especially for larger diameters Forstner bits wander and bind when used freehand at an angle.
- Speed
- Lower RPM as diameter increases Large bits burn the wood and lose their temper at high speed.
- Center spur
- Short center spur for shallow holes in thin stock A long spur can break through the back before the hole reaches depth.
Brands that matter
- Freud: Precision Shear line for woodworking.
- Fisch: Premium Austrian Forstner bits.
- Colt: Highly regarded German Forstner maker.
- Bosch: Common DIY Forstner sets.
What to avoid
