Two new Cat Performance Series Hammers

Cat H215 S hydraulic hammer

New hammers designed to deliver high-production, low-maintenance operation on large excavators

BUILT for high production on large excavators, the new Cat H190 S and H215 S Performance Series hammers deliver consistent breaking power. Their extremely efficient operation cycle results in less waste from internal heat for more power delivered to the tool.

With piston and tool matched in diameter and mass, these new hammers are said to offer increased power transmission frequency. Operators can switch power mode from high frequency/low power to low frequency/high power, giving the ability to fine tune power to the material being broken.


While powerful, the new H190 S and H215 S hammers lead in operator comfort and machine protection with their proprietary buffering material that dampens vibration feedback to the carrier. The flexible hammers can be configured for joystick or pedal control to suit the operator’s preference when working in quarry, demolition, and general construction applications.

Tuned to deliver the highest possible work rates with Cat next-generation excavators, the new H190 S hammer is sized for operation on Cat 349 to 374 models, whilst the larger H215 S (pictured) is designed for the 374 and 395 machines. Auto Stop instantly terminates hammering/blank firing when the tool breaks through material, preventing damage to both the carrier and hammer.

Next-generation excavators automatically recognize the H190 S and H215 S hammers and prompt operators to select the correct tool program. Protecting the cab and keeping the attachment in predefined operating areas at the jobsite, the new hammer dimensions are included in Cat E-Fence technology. Through the Cat excavators Product Link technology, users can quickly locate the hammer attachment using the Cat App.

Hammer pressure and flow rates are viewed on the in-cab monitor and can be configured manually or automatically using the touchscreen display. To save time, all daily checks and routine service can be performed without removing the new H190 S and H215 S hammers from the carrier. Steady internal gas pressure throughout the duration of the annual service interval eliminates the need for frequent charge inspection.

The lower bushing’s rotatable design optimizes service life to minimize parts costs, whilst the bushing can be quickly serviced in the field using hand tools. A standard on-board autolube system provides continual greasing during hammer operation to improve attachment longevity, and for operations in extreme environments, an optional wear package protects the hammer housing from damage.
