Introduction
The Bosch HC5030 SDS-max Speed-X Rotary Hammer Bit is engineered for efficient drilling in concrete and masonry. This 3/4 inch diameter, 13 inch long bit features a carbide-tipped X-head designed for extended sharpness and durability. It is compatible with Bosch SDS-max hammers and other competitive SDS-max drive hammers, including Hilti hammers utilizing TE-Y and TE-FY shanks. The design adheres to ANSI specification B212.14, ensuring reliable performance.
Key design elements include a solid carbide head with a robust S-cutter for enhanced speed and bit life, and an optimized shank to resist wear over time. Bosch's commitment to innovation in concrete and masonry drilling is reflected in the advanced carbide technology and diffusion bonding used in this bit, resulting in superior performance and durability.

Safety Information
Always prioritize safety when operating power tools and accessories. Failure to follow safety guidelines can result in serious injury.
- Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, and a dust mask when drilling. Gloves are recommended to protect hands.
- Tool Compatibility: Ensure the SDS-max rotary hammer bit is correctly matched to your SDS-max rotary hammer drill. Do not force the bit into an incompatible chuck.
- Inspect Bit: Before each use, inspect the drill bit for any signs of damage, cracks, or excessive wear. Do not use damaged bits.
- Secure Workpiece: Always secure the material you are drilling to prevent movement during operation.
- Maintain Control: Hold the rotary hammer firmly with both hands. Be prepared for torque reactions, especially when the bit binds or breaks through the material.
- Avoid Overheating: Allow the bit to cool periodically during prolonged use to prevent overheating and premature wear.
- Dust Management: Drilling concrete generates dust. Use appropriate dust extraction systems or work in a well-ventilated area.
- Electrical Safety: Be aware of hidden electrical wires or plumbing in walls before drilling. Use a detector if necessary.
Setup
- Select Correct Bit: Choose the appropriate diameter and length of the SDS-max bit for your application. The HC5030 is 3/4 inch in diameter and 13 inches long.
- Clean Shank: Ensure the SDS-max shank of the drill bit is clean and free of dust or debris. A light coating of grease on the shank can improve performance and reduce wear.
- Insert Bit: Pull back the collar on your SDS-max rotary hammer. Insert the bit into the chuck, rotating it slightly until it clicks into place. Release the collar.
- Verify Engagement: Gently pull on the bit to ensure it is securely locked in the chuck. The bit should have a small amount of axial play; this is normal for SDS-max systems.

Operating Instructions
- Mark Drilling Location: Clearly mark the precise location for drilling on your workpiece.
- Start Drilling: Place the tip of the bit on the marked spot. Start the rotary hammer at a low speed to create a pilot indentation, then increase to full speed.
- Apply Steady Pressure: Apply firm, steady pressure to the tool. Allow the rotary hammer action to do the work; excessive force can reduce drilling efficiency and damage the bit or tool.
- Maintain Straight Angle: Keep the drill bit perpendicular to the drilling surface throughout the process to ensure a straight hole and prevent bit breakage.
- Clear Debris: The large flute design helps clear debris. For deep holes, periodically withdraw the bit slightly to assist in dust removal.
- Monitor Wear Mark: The wear mark indicator on the bit helps ensure the drilled hole remains within specification for anchor installation. If the wear mark is no longer visible, the bit may be worn beyond acceptable limits for precise anchor fitting.
- Finish Drilling: Once the desired depth is reached, withdraw the bit from the hole while the tool is still running to clear any remaining debris.

Maintenance
- Cleaning: After each use, clean the drill bit to remove concrete dust and debris. A wire brush can be used for the flutes, and a cloth for the shank.
- Lubrication: Apply a thin layer of SDS-max grease or a general-purpose lubricant to the shank of the bit periodically to ensure smooth insertion and removal from the chuck and to reduce wear.
- Inspection: Regularly inspect the carbide tip for chips, cracks, or excessive wear. Check the flutes for signs of damage or clogging. A severely worn or damaged bit should be replaced to maintain performance and safety.
- Storage: Store drill bits in a dry place to prevent rust. Keep them in their original packaging or a dedicated bit case to protect the tips from damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow drilling progress | Worn bit tip; insufficient pressure; incorrect drill mode (not in hammer mode); drilling into rebar. | Replace bit if tip is dull; apply steady, firm pressure; ensure rotary hammer is in hammer drill mode; adjust drilling location if hitting rebar. |
| Bit binding or getting stuck | Excessive side pressure; drilling at an angle; insufficient dust removal; hitting an obstruction. | Maintain straight drilling angle; periodically withdraw bit to clear debris; use a detector to avoid obstructions. |
| Excessive bit wear or breakage | Overheating; incorrect application (e.g., drilling metal without proper cooling); excessive force; impact with hard aggregate. | Allow bit to cool; ensure correct application; use appropriate pressure; inspect bit regularly. |
| Hole diameter is too large or inconsistent | Worn wear mark indicator; bit wobble due to loose chuck or worn tool. | Replace bit if wear mark is gone; ensure bit is securely seated in chuck; inspect rotary hammer for chuck wear. |
