Buying Guide: Key Purchase Considerations
- Material compatibility: For hard metals like stainless steel, consider cobalt or carbide-tipped bits and tools designed for metal without excessive wear.
- Drill type and arbor compatibility: Ensure the bit’s shank and arbor fit your drill or drill press, and verify whether a pilot bit or arbor is included.
- Bit type choice: Step drill bits excel at enlarging holes in metal sheets with multiple diameters in one tool, while hole saws are better for larger, clean circular holes in metal, wood, or PVC.
- Cutting speed and heat management: Hard metals require appropriate speeds and lubrication to minimize heat buildup and extend bit life.
- Durability features: M42 cobalt, titanium coatings, and carbide tips offer longer life in demanding jobs; bi-metal designs provide flexibility and resilience for versatile work.
- Hole size range and depth: Check the maximum diameter and cutting depth to ensure the bit meets your project needs, especially for stainless steel or thick metal sheets.
- Chip clearing and geometry: Flute design and chip removal paths reduce jamming and improve cutting efficiency on metal surfaces.
- Maintenance: Clean and lubricate bits after use, and store in a dry environment to prevent corrosion and maintain sharpness.
