Buying Guide
What should you consider when choosing a drill bit sharpener?
- Bit size range: Ensure the sharpener covers the diameters you most often use, from small micro bits to larger bits.
- Angle options: Common sharpening angles are around 118° to 135°. Choose a model offering the angles you need for your material and bit type.
- Shaping and tip design: Some units offer edge splitting to reduce wear and improve cutting efficiency. This can extend bit life in tougher materials.
- Portability and footprint: If you have limited space or need a portable solution, consider a compact design with a straightforward setup.
- Power and connectivity: Decide between electric plug-in sharpeners and manual or jig-based systems based on your work environment.
- Compatibility: For grinders that convert to sharpeners (jigs), verify compatibility with your current grinder model and wheel size.
- Durability: Look for units with durable wheels (diamond wheels preferred) and stable guides to ensure consistent angles and edge quality.
How do you match a sharpener to your workflow?
- High-volume workshop: Look for a model with a wide range, adjustable angles, and a durable wheel—facilitates fast, repeated sharpening.
- Garage or hobbyist: A simpler two-step system with stable guides may be sufficient and easier to use.
- Light repair and maintenance: Jigs or compact sharpeners can handle occasional bit repair without a large investment.
Maintenance tips for longer bit life
- Keep the sharpening wheel clean and properly lubricated if required by the model.
- Regularly inspect the bit edge for uniformity; uneven edges indicate misalignment or wear.
- Avoid overheating bits; allow cooling intervals during longer sharpening sessions.
