ROCK & CONCRETE GRINDERS

With technology evolved from the mining industry, Alpine's hydraulic rock and concrete cutting attachments (Cutterheads) are a versatile tool with many uses and are an excellent alternative to conventional hydraulic hammers. Equipped with carbide teeth and able to generate massive torque and cutting forces, Alpine’s line of cutterheads is unmatched in concrete grinding and rock cutting applications. Cutterheads offer the ideally engineered balance of cutting power and precision.

GRINDERS ACCESSORIES
  
Rototop 360 Swivel bracket:
Rototop enables 360o swivel of the Alpine Cutter Head, making it incredibly effective in detailed work such as scaling jobs and precision excavation. The combination cutter head and Rototop improves overall efficiency of the cutter head on the job site by reducing carrier movement as well as reducing pick wear.
Quick Hitch Bucket for Grinders:
Alpine Cutter/Grinder with a Quick-Hitch bucket offers two-tools-in-one for effecient excavation and cutting with the benefit of a removable bucket. Perfect trenches in no time.
  Depth Guide:
The precision of the Alpine Cutter Head is unmistakable but in certain projects tight tolerances are necessary. Alpine can provide custom depth guides to assure that tight, even tolerances are met.
   
Drums:
Alpine Cutter Heads are shipped with drums suitable for most rock and concrete applications with additional drums available for more specialized applications. Alpine offers Rock, Scaling, Demolition, and extra wide drums for each cutter head model. We also provide custom drums for special applications. In addition to rock cutting/grinding drums, Alpine offers more specialized drum attachments including a slot cutter, industrial brush, soft rock/high production drum, and several soil mixing and conditioning drums.
   
Rock Drums:
Come standard on most Alpine Cutter Head models. Excellent all-around cutter and grinder and we recommend these drums most often. Rock drums are top notched for rock of all hardness and
scaling concrete.
Demolition Drums:
Built with a raised helix inbetween cutting picks to limit penetration and reduce cutting vibration.
Scaling Drums:
Built with considerably higher number of picks, this drum is best for very precise grinding applications.
