The Simpson SDS-Max Flat Scaler Chisel 1-1/2 in x 12 in is a professional-grade demolition chisel built for heavy-duty material removal on concrete, masonry, and similar hard surfaces. Engineered with a 1 1/2 in. wide flat scaler profile and 12 in. of overall length, this bit delivers the broad contact edge and reach needed to strip deteriorated concrete, remove mortar and tile adhesive, and prepare surfaces for patching or overlay work. Precision-crafted in Germany, it reflects the exacting material standards and quality control that demanding jobsite conditions require.

Key Features

• SDS-Max Shank - Provides a secure, vibration-dampening connection to SDS-Max rotary hammers and allows fast, tool-free bit changes, reducing downtime on the job.
• 1 1/2 in. Wide Flat Scaler Profile - Delivers a broad, flat cutting edge that covers more surface area per strike, making large-scale scaling and demolition work faster and more efficient.
• 12 in. Overall Length - Offers extended reach into confined or recessed areas while maintaining the control needed for precise surface preparation work.
• Resharpening Capability - The scaler edge can be resharpened when it dulls, extending the usable life of the chisel and reducing long-term replacement costs.
• Specialized Tempering and Hardened Surface Treatment - Creates a wear-resistant surface that stands up to repeated impact against concrete, block, and masonry substrates without premature degradation.
• German Precision Engineering - Manufactured to tight tolerances with high material standards, ensuring consistent dimensional accuracy and reliable performance across demanding applications.

Why This Product

• Built to Work Harder, Longer - A hardened, wear-resistant surface treatment combined with a resharpening-capable cutting edge means this scaler chisel stays productive well beyond a single use, giving buyers a tool that earns its cost over time.

Frequently Asked Questions

What type of rotary hammer is the CHMXSC15012 compatible with?

The CHMXSC15012 is designed for use with SDS-Max rotary hammers. The SDS-Max shank provides a secure, vibration-dampening fit and allows for fast, tool-free bit changes in any compatible SDS-Max tool.

What are the dimensions of this flat scaler chisel?

The CHMXSC15012 measures 1-1/2 inches wide and 12 inches in overall length, making it well suited for heavy-duty scaling and demolition work where reach and a broad contact edge are needed.

Can the cutting edge of this chisel be resharpened after it dulls?

Yes. The scaler edge of the CHMXSC15012 is designed to be resharpened whenever necessary. This extends the usable life of the tool and reduces the need for frequent replacement, making it a cost-effective option for demanding jobsite use.

What type of steel and surface treatment does this chisel feature?

The CHMXSC15012 is constructed from toughened steel selected specifically for demolition and heavy-duty chiseling applications. It also undergoes a specialized tempering process that produces a hardened, wear-resistant outer surface capable of withstanding continuous impact loads.
