FAQs
What material is this pilot drill made from?
This pilot drill is made from HSS-G (High-Speed Steel – Ground) material, known for its durability and wear resistance.
What is the primary function of this pilot drill?
Its primary function is to drill pilot holes for accurate starting points and to guide hole saws during cutting operations.
Will this pilot drill fit any drill chuck?
It is designed to fit securely in standard three-jaw drill chucks and ¼" internal hex tool holders due to its hex shank.
Can I use this drill bit for holes larger than 6.35 mm?
No, this bit is specifically for drilling small pilot holes and guiding. For larger holes, you would use a hole saw attached to an arbor that incorporates this type of pilot drill.
What are the dimensions of this pilot drill?
The dimensions are 6.35 mm in diameter and 44 mm in length.
How do I maintain the pilot drill?
Keep it clean and dry to prevent rust. Store it properly and avoid using excessive force during operation.
Troubleshooting
Pilot drill wobbles or slips during use.
Ensure the hex shank is fully inserted and the drill chuck or tool holder is tightened securely. Check the drill chuck for wear or damage.
Pilot drill tip breaks easily.
Reduce drilling pressure. Ensure the pilot hole is correctly sized and not obstructed. Verify the material being drilled is suitable for the HSS-G bit.
Difficulty starting a clean pilot hole.
Ensure the drill is set to the correct speed (lower speeds for harder materials). Use a center punch to create a starting indentation if drilling into very hard surfaces.

Setup, Compatibility & Care
Setup:
- Insert the 6.35 mm hex shank of the pilot drill into the chuck of your drill or ¼" internal hex tool holder.
- Tighten the chuck securely to ensure a firm grip on the shank.
- If using with a hole saw arbor, ensure the pilot drill fits snugly into the arbor's pilot hole guide.
Compatibility:
- Drill Chucks: Compatible with standard three-jaw drill chucks.
- Tool Holders: Compatible with ¼" internal hex tool holders.
- Hole Saws: Designed to work with standard hole saw arbors where a pilot drill is incorporated.
Care:
- After use, remove any dust or debris from the pilot drill.
- Store in a dry place to prevent rust.
- Avoid excessive force or improper use that could bend or break the bit.
- Periodically check the sharpness of the tip; re-sharpening is possible but often replacement is more economical for this type of accessory.
