Buying Guide: Key Purchase Considerations
- Material and durability: Cobalt (M42) bits excel in hardened metals; titanium-coated bits offer extended life on metal and wood.
- Point geometry: Split points and pilot points reduce walking and improve hole accuracy, especially in metal and plastic.
- Shank design: Three-flats, quick-change, or conventional round shanks affect chuck grip and compatibility with drill types.
- Bit assortment and storage: Larger sets provide versatility but may require organized storage; consider included cases and labeling.
- Applications: Match bits to tasks—wood, metal, plastic, masonry, and specialized metals—to ensure efficiency and clean results.
- Maintenance: Keep bits sharp, use proper lubrication for metals, and avoid overheating to prolong life.
