AWTools SDS+ 28mm Drill Bit

The AWTools SDS+ 28mm drill bit is a high-performance rotary hammer drill bit engineered specifically for drilling into hard masonry materials including concrete, brick, and stone. Equipped with an SDS-plus shank, this drill bit ensures secure chuck retention and facilitates efficient energy transfer from the rotary hammer to the drilling surface. Designed to meet the demands of rigorous applications, it provides reliable and precise performance for various construction and renovation projects.

Advantages

This drill bit offers exceptional durability and strength, making it well-suited for demanding drilling tasks in tough building materials. The SDS-plus shank design allows for fast, tool-free bit changes while ensuring maximum impact energy delivery during operation. Its robust construction minimizes wear and tear, contributing to a longer operational lifespan even under frequent professional use. The 28mm diameter allows for creating large, accurate holes required for heavy-duty anchors, piping, and wiring installations.

Suitable for

• Drilling large-diameter holes in concrete, solid brick, and natural stone
• Heavy-duty construction and professional renovation projects
• Installing structural anchors, conduits, and heavy fixtures
• General masonry work requiring an SDS-plus rotary hammer

When it may not be suitable

This drill bit is not designed for drilling into metal, wood, or soft plastics, as the aggressive geometry and impact action may damage the material or the bit itself. It is also not compatible with standard three-jaw drill chucks found on regular power drills without an appropriate adapter, as it requires an SDS-plus rotary hammer to function correctly.

Key specifications

• Bit diameter: 28 mm
• Shank type: SDS-plus
• Compatible materials: Concrete, brick, stone, and masonry
• Application: Rotary hammer drilling

How to use

Insert the drill bit directly into the SDS-plus chuck of your rotary hammer until it clicks securely into place. Ensure the tool is unplugged or the battery is removed before inserting or changing bits. Position the tip of the drill bit perpendicular to the targeted masonry surface and apply steady, moderate pressure while operating the rotary hammer. Allow the tool and bit to do the work, avoiding excessive lateral force. Periodically withdraw the bit from the hole during deep drilling to clear out accumulated masonry dust and prevent overheating.

What to consider before purchase

• Verify that your power tool features an SDS-plus chuck compatibility
• Ensure the 28mm hole diameter matches the requirements of your project fasteners or pipes
• Confirm the intended application involves hard masonry materials rather than wood or metal

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses, hearing protection, and a dust mask when drilling into masonry. Keep the bit clean and inspect it regularly for signs of wear or damage to ensure safe and efficient operation.
