When you’re prepping concrete for an exterior finish, the Diablo DMAMXCH1050 9-1/4" SDS-Max Bushing Tool is engineered to deliver consistent texture, exceptional durability, and reliable stability. Built to handle demanding hammer-drill work, this tool helps you achieve a clean, even surface ready for coatings, veneers, or stucco without slowing down your workflow.

Engineered for brutal conditions and steady results

Diablo’s SDS-Max Bushing Tools are crafted to endure the rigors of high-powered hammer drills. A unique heat treatment strengthens the steel body, resisting the stress of heavy impacts and repeated contact with tough concrete. The result is a tool that maintains precise alignment and reduces wandering, giving you predictable performance batch after batch.

Optimized for SDS-Max performance

Designed with compatibility in mind, this 9-1/4" bushing tool is optimized for maximum efficiency in both corded and cordless SDS-Max rotary hammers. Whether you’re on a job site with a plugged-in hammer or working with a battery-powered unit, you’ll experience steady material removal and controlled texture progression that helps you hit your exterior finish goals faster.

Use cases that translate to real-world results

• Roughing concrete surfaces to create the textured base needed for stucco, veneer, or decorative coatings.
• Preparing foundation walls and exterior surfaces where a uniform texture improves adhesion and longevity of subsequent layers.
• Creasing and high-traction surface prep on driveways or walkways to ensure coatings grip evenly.

Why this tool stands out

• Durability you can count on: heat-treated steel minimizes wear and maintains stability under heavy hammer impact.
• Designed for SDS-Max versatility: performs reliably with both corded and cordless SDS-Max hammers, expanding where you can work and how long you can work.
• Large-pass tool for efficiency: at 9-1/4" in length, it covers more surface area per pass, reducing cycle times on exterior finish prep.
• Consistent results: built to hold steady contact and produce uniform texture, helping coatings and finishes adhere better and last longer.

Tips for best results

For optimal texture and coating adhesion, pair this tool with a steady, controlled cutting motion and stay aware of dust management and PPE. Start with a moderate feed rate to establish a uniform pattern, then adjust to increase material removal where needed. Regularly inspect the tool for wear and maintain proper alignment to preserve stability and accuracy across long jobs.
