What the Makita HM1812X3 Breaker Hammer Is Designed For

This breaker hammer is a workhorse for major demolition tasks, ideal for:

• Breaking concrete slabs, foundations, sidewalks, and driveways

• Digging and trenching in hard-packed soils

• Removing asphalt, tile, and stone

• Industrial and commercial demolition operations

• Roadwork and utility excavation

• Structural removal tasks including piers, beams, and footers

The HM1812X3 is engineered to outperform pneumatic breakers without the need for a compressor—making it a top choice for job sites where mobility, power, and control are essential.

Unmatched Power and Performance

70-Pound Demolition Force

At 70 pounds, the HM1812X3 is heavy enough to deliver massive striking force, yet balanced for stable operation. Its weight helps drive each impact deeper into the material, increasing productivity and reducing operator effort.

High Impact Energy Output

Engineered for industrial-grade force, this breaker hammer produces powerful and consistent strikes capable of shattering heavily reinforced concrete. The combination of motor efficiency and engineered gearing ensures maximum demolition speed.

Electric-Powered Performance with No Compressor Needed

Unlike pneumatic hammers, this electric model eliminates the need for bulky air compressors, hoses, and additional equipment. This makes operation simpler, more mobile, and highly efficient across all job environments—indoor, outdoor, commercial, or residential.

Advanced Anti-Vibration Technology (AVT®)

One of the defining features of the Makita HM1812X3 is its AVT® system—Makita’s most advanced integrated vibration reduction technology.

How AVT® Improves Productivity and Comfort:

• Internal counterbalance system reduces tool vibration dramatically.

• Isolator handles absorb shocks before they reach the operator’s arms.

• Soft-start electronics provide smoother ramp-up control.

• Reduced fatigue allows contractors to work longer and more comfortably.

This technology is especially beneficial during full-day demolition tasks where operator endurance impacts job productivity.

Precision and Control Under All Conditions

Soft-Start Performance

The soft-start function ensures smooth motor engagement, reducing the risk of early chipping or material misalignment and enabling precise placement before full force is applied.

Constant Speed Control

Even under heavy load, the HM1812X3 maintains consistent power output for steady, predictable demolition—resulting in uniform removal across the work surface.

Automatic Brush Cut-Off

This feature protects the motor from damage, increases longevity, and reduces maintenance downtime.

Durable Construction for Harsh Job Sites

Every part of the HM1812X3 is engineered for extreme durability:

• Reinforced metal housing protects internal components.

• Industrial-grade gearing increases lifespan and reduces wear.

• Heavy-duty power cord withstands bending, abrasion, and job-site use.

• Dust-sealed components enhance long-term reliability.

Built to survive the harshest environments, this breaker hammer is made for contractors who rely on their tools day after day.

1-1/8" Hex Shank for Maximum Compatibility

The 1-1/8" hex shank is the industry standard for heavy demolition tools. This ensures secure bit retention, reduced slipping, and compatibility with a wide range of professional-grade demolition steels.

Benefits of the 1-1/8" Hex System:

• Stronger bit grip for heavy-duty hammering

• Reduced wear on both tool and bits

• Ability to use universal industry-standard accessories

This makes the HM1812X3 a versatile option for contractors already using hex-system tools.

Four-Piece Premium Steel Bit Set Included

The Makita HM1812X3 kit includes four high-performance demolition bits, each designed for specific tasks:

1. Pointed Chisel

Ideal for breaking through thick concrete, creating fracture lines, and penetrating dense materials.

2. Flat Chisel

Perfect for scaling, smoothing, and removing layers of tile or concrete.

3. Narrow Chisel

Excellent for cutting, trenching, and controlled material removal.

4. Asphalt Cutter

Designed specifically for cutting through asphalt, making this hammer ideal for roadwork, patching, or utility access tasks.

These bits are forged from premium steel, heat-treated for durability, and built to withstand massive impact loads.

Premium Job-Site Transport Cart

The included heavy-duty cart makes transporting the 70-pound breaker hammer simple and safe.

Cart Benefits:

• Large wheels navigate rough job-site terrain easily.

• Secure holder keeps the hammer locked in place during transport.
