The Simpson SDS-Max Flat Chisel Scaler is a heavy-duty demolition bit built for professionals who need to remove large quantities of material with confidence and control. Engineered with an SDS-Max shank and a wide 2 in. flat profile across a 12 in. working length, this flat scaler is purpose-built for scaling concrete, chipping bonded layers, and preparing surfaces ahead of repair or resurfacing. A specialized tempering process produces a hardened, wear-resistant cutting edge that holds up under the sustained impact of demolition hammers - and can be resharpened when needed, keeping the tool productive long after initial use.

Key Features

• SDS-Max Shank - Locks securely into any SDS-Max rotary hammer or demolition hammer for tool-free bit changes and maximum power transfer during heavy-duty impact work.
• 2 in. Wide Flat Profile - Covers more surface area per pass compared to narrower chisels, making it especially efficient for scaling concrete, masonry, and similar hard surfaces.
• 12 in. Working Length - Provides the reach needed to access recessed areas and work comfortably without overextending the tool or the operator.
• Specialized Tempering Process - Creates a hardened, wear-resistant surface that withstands the rigors of repeated demolition use, reducing downtime from premature edge failure.
• Resharpenable Cutting Edge - The scaler edge can be resharpened as needed, extending the useful service life of the bit and delivering long-term value over repeated use cycles.

Why This Product

• Built for high-volume material removal - The wide 2 in. flat blade is specifically engineered for removing large quantities of material during demolition work, making it a practical choice for scaling, chipping, and surface preparation tasks.
• Longer service life by design - The hardened, wear-resistant surface created by the tempering process - combined with a resharpenable edge - means this chisel can be maintained and reused rather than replaced at the first sign of dullness.
• Versatile across common demolition applications - From scaling concrete and masonry to breaking bonded or layered materials and preparing surfaces for resurfacing, this flat scaler covers a broad range of heavy-duty site tasks with a single tool.
• Precision-fit SDS-Max compatibility - The SDS-Max shank ensures a secure, wobble-free connection with compatible hammers, so energy from each impact stroke translates directly into effective material removal rather than being lost at the shank interface.

Frequently Asked Questions

What type of hammer is this chisel compatible with?

The CHMXSC20012 features an SDS-Max shank, making it compatible with SDS-Max rotary hammers and demolition hammers. The SDS-Max connection allows for secure, tool-free bit changes and ensures maximum power transfer during use.

What are the dimensions of this flat scaler?

This flat scaler measures 2 inches wide and 12 inches in length, providing a wide flat profile optimized for scaling and removing large quantities of material efficiently.

Can the cutting edge be resharpened once it becomes dull?

Yes. The CHMXSC20012 is designed with a resharpenable cutting edge, meaning the scaler edge can be resharpened as needed. This feature extends the useful life of the tool and delivers long-term value over repeated use.

What makes this chisel suitable for heavy-duty demolition work?

The chisel is constructed from toughened, high-grade steel and undergoes a specialized tempering process that creates a hardened, wear-resistant surface layer. An additional special surface treatment further enhances performance and protects the chisel under heavy use conditions, allowing it to withstand the repeated impact stress of demanding demolition applications.
