Hawk Concrete Floor Grinder - made in USA.USA Engineered & Made

  • Setting new records in production, easy of use, durability, versatility, maintenance - minimal (if any)!

  • Operates all day from 120 volt, 20 amp breaker.

Features & Benefits:

  • HIGH-TORQUE MOTOR - 1.5 HP TEFC AC motors (totally enclosed fan cooled) - motors are protected from dust, debris and slurry.

  • GEARS:  11:1 Gear Ratio, Triple X-HD, Helical-Cut Industrial Gears.  Produces high torque to drive scrapers & metal diamonds with minimal amp draw

  • DIRECT-DRIVE & STEEL COUPLER (vs. belt-driven, planetary grinders):  plows through the thickest coatings without tripping a 20 amp circuit, and no coupler or belts to break.

    • Direct-Drive:  Industrial grade metal drive shaft, direct connection from the motor to the drive plate, produces far superior torque while only draws 14.9 amps

    • Belts & Pulleys:  used in planetary grinders to increase their RPM speed (speed is used for polishing.)  However, torque is greatly diminished;  to off-set this, planetary grinders rely on extreme weight to grind concrete and remove coatings.

  • FLOATING HEAD - unique design provides 100% contact with the floor.  The heads flex by moving move up and down and following the contour of the floor.  Self-adjusting prevents scraps on bumps, avoids dig-ins, provides a consist, uniform finish.

  • APPLICATIONS - Does it All:  HD grinding, concrete & stone polishing, coating & sealer removal, scarification, deep cleaning of concrete, natural stone and other hard surfaces

  • Engineered to finish within 1/2" of walls

  • Equipped with forward and reverse on the driver to navigate irregular surfaces and to avoid obstacles

  • Swing machine vs. wheels-down machine.WHEELS DOWN - Important:  Steer forward and backward and turn unlike the side-to-side movement of a swing machine (right) which is hard to control and requires a long learning curve often taking days to master.  With a wheels-up/swing machine you are constantly fighting against its swinging movement especially during high torque grinding and coating removal projects. 

    FACT:  For concrete grinding and coating removal, high torque is required.  With a wheels-down machine, unskilled workers can become experts within minutes and worker fatigue is reduced 120%.

  • 360° DUST COLLECTION - dust collection system is built into the head cover ~ will not disappoint.  Directs the dust upwards to the 2" vacuum port.

  • Foot Operated Tilt Back for Easy Transporting

  • Dual steel operating triggers with negative pressure on/off switch

  • Disassembles for easy handling down stairs

  • Thumb-operated safety switch with comfort cushion grips

  • 2-PIECE DESIGN:  allows the handle-carriage to be easily separated from the dual motor head - advantageous when the machine needs transported in to hard to reach locations such as basements or mezzanines.

 


 

Diamond Driver Plate - Included:

  • Counter-rotating for ergonomically balance, ease-of-use and minimal learning curve.

  • Plate accepts a complete assortment of tooling (shown below) for grinding, coating removal, polishing, and to scarify.
