Buying Guide: 90 Degree Drill Jig Considerations
- Angle range and settings: Decide if you need fixed angles (30°, 45°, 90°) or adjustable ranges (±45°).
- Drill size compatibility: Confirm the maximum drill bit diameter supported by the guides (commonly 1/2″ or smaller).
- Portability vs. robustness: Compact jigs are easy to transport; heavier models may offer greater stability and durability on bigger projects.
- Attachment method: Check whether the jig clamps to the workpiece or attaches to your drill, and choose based on your workflow.
- Dust and depth control: Built-in dust collection and depth stops help maintain cleanliness and consistent hole depth.
- Included bits and accessories: Some sets include multiple bits and sizes; evaluate if you’ll need additional bits for your typical projects.
- Material and build quality: Look for hardened steel guides or anodized aluminum for long-term wear resistance.
