Safety Information
Always observe general safety precautions when working with power tools and accessories. Failure to follow these instructions may result in injury or damage to the tool or workpiece.
- Wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and gloves.
- Ensure the drill bit is securely seated in the hammer drill chuck before operation.
- Do not exceed the maximum rotational speed recommended for your hammer drill and the material being drilled.
- Avoid applying excessive force, which can cause the bit to bind or break.
- Disconnect the power tool from the power source before changing accessories or performing maintenance.
- Keep hands and loose clothing away from rotating parts.
- Check the workpiece for hidden electrical wires, gas pipes, or water pipes before drilling.

Setup
- Select the Correct Drill Bit: Ensure the Hilti 2038077 TE-C 3/8" x 12" SDS PLUS drill bit is appropriate for your application and material.
- Prepare the Hammer Drill: Ensure your rotary hammer drill is unplugged or its battery is removed before installing the bit.
- Insert the Drill Bit:
- Pull back the chuck collar on your SDS PLUS rotary hammer drill.
- Insert the SDS PLUS shank of the drill bit into the chuck until it clicks into place.
- Release the chuck collar.
- Pull on the drill bit to ensure it is securely locked. There should be a slight amount of play, which is normal for SDS PLUS systems.
- Inspect the Bit: Before use, check the drill bit for any signs of damage or excessive wear. Do not use damaged bits.
Operating Instructions
Follow these steps for optimal performance and safety when using your Hilti hammer drill bit:
- Mark the Drilling Location: Clearly mark the precise spot where you intend to drill.
- Position the Drill: Hold the hammer drill firmly with both hands. Position the tip of the drill bit directly on the marked spot.
- Start Drilling:
- Start the drill at a low speed to create a pilot indentation, preventing the bit from wandering.
- Once the bit has engaged the material, increase the speed and apply steady, moderate pressure.
- Allow the hammer action of the drill to do the work; excessive force is not required and can reduce bit life.
- Maintain Drilling Angle: Keep the drill bit perpendicular to the drilling surface throughout the process to ensure a straight hole.
- Clear Debris: Periodically withdraw the drill bit slightly from the hole to allow dust and debris to escape, especially when drilling deep holes. This helps prevent clogging and overheating.
- Finish Drilling: Once the desired depth is reached, slowly withdraw the drill bit from the hole while the drill is still running to clear any remaining debris.
Note: For optimal performance and to prolong bit life, avoid overheating. If the bit becomes excessively hot, allow it to cool before continuing.
Maintenance
Proper maintenance ensures the longevity and performance of your Hilti drill bit.
- Cleaning: After each use, clean the drill bit to remove dust and debris. A stiff brush or compressed air can be used.
- Inspection: Regularly inspect the carbide tip for chipping or excessive wear. Inspect the shank for damage. Replace the bit if it shows significant wear or damage.
- Storage: Store drill bits in a dry place to prevent rust. Keep them in their original packaging or a dedicated drill bit case to protect the tips.
- Lubrication (Shank): A small amount of grease on the SDS PLUS shank can help reduce wear on the chuck and improve bit insertion/removal.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bit not drilling effectively | Worn or dull carbide tip; insufficient hammer action; incorrect drill speed. | Replace the drill bit; ensure hammer function is engaged on the drill; adjust drill speed. |
| Bit overheating | Excessive pressure; insufficient debris removal; drilling too fast. | Reduce pressure; frequently withdraw bit to clear debris; reduce drill speed; allow bit to cool. |
| Bit binding or getting stuck | Drilling at an angle; hitting rebar or hard aggregate; hole not cleared of debris. | Maintain a straight drilling angle; clear debris; if hitting rebar, consider a rebar-cutting bit or relocate the hole. |
| Excessive vibration | Damaged or bent drill bit; improper bit seating in chuck. | Inspect and replace damaged bit; ensure bit is correctly inserted and locked in the chuck. |
