Best for longevity and fast starts, this Makita set uses titanium nitride coating that lasts up to 2.5x longer than standard bits.

Choose this if your work demands long bit life and reliable starts in tough materials.

Best for metal-focused projects where precision matters, the TiN-coated bits resist wear in repeated uses. A potential limitation is that extremely hard materials may still wear down faster than premium purpose-built metal bits, so plan rotations accordingly.

Buying Guide: Key Purchase Considerations

• Compatibility: Ensure 1/4″ hex shank bits fit your impact driver. Some sets include quick-change adapters for convenience.
• Coating and Material: Titanium or TiN coatings extend life in metal drilling. HSS bits perform well across wood and metal.
• Point Geometry: 135° split points reduce walking on startup and improve initial bite, especially in metal and harder plastics.
• Shank Type and Quick Change: Quick-change systems save time on multi-bit tasks; keep the case organized to avoid misplacing bits.
• Chip Clearance and Flute Design: Two-flute or staggered teeth designs help remove chips and reduce heat buildup during drilling.
• Durability vs. Range: Large kits offer size variety but may sacrifice focus. For professional use, prioritize durability and bit count that matches typical tasks.
