Hawk F75 Concrete Floor Grinder | Surface Preparation & Coating Removal

Hawk F75 Concrete Floor Grinders

Direct-Drive, High-Torque Gear System --- Produces powerful torque for HD:

Concrete grinding and coating removal of epoxy, sealers, mastics, adhesives without tripping a 15-amp circuit
Advantage over a planetary grinder: they require large power circuits and heavy weight --- The Hawk F75 Solves This.

Built for Concrete Surface Preparation Work: Grinding, Coating Removal, Polishing.

Two sizes: 17" and 20"

Perfect for contractors performing:

Features & Benefits:

FLOATING HEAD - unique design provides 100% contact with the floor. The heads flexs by moving and adjusting to the contour of the floor. 100% automatic and self-adjusting, scraps and digs into the floor are prevented, a consistent and uniform finish is produced.
Engineered to finish within 1/2" of walls
Equipped with forward and reverse on the driver to navigate irregular surfaces and to avoid obstacles
F75 WHEELS DOWN MACHINE - IMPORTANT: Comfortable and easy steer, turn and maneuver a F75, unlike the side-to-side movement of a swing machine (right) which requires a long learning curve - often taking days to master.

With a wheels-up / swing machine, you are constantly fighting against its swing movement especially during high torque grinding and coating removal projects.

FACT: For concrete grinding and coating removal, high torque is required. With a F75 wheels-down machine, an unskilled worker will become an expert 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

Heavy-Duty Design:

2-PIECE ASSEMBLY: allows the handle-carriage to be easily separated from the motor head - advantageous when the machine needs transported in to hard to reach locations such as basements or mezzanines.
MAINTENANCE & SERVICE - Locally made and built in Elkhart, Indiana. All parts are readily available. Bonus: As a direct-drive machine vs. belts-and-pulley, first, there are no belts-and-pulleys to replace, and maintenance-wise, it's minimal if any.
HIGH-TORQUE MOTOR - 1.5 HP TEFC (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 that is required to drive scrapers & metal diamonds with minimal amp draw
DIRECT-DRIVE plus STEEL COUPLER Vs. Belt-Drive Planetary Grinder: Plow 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 and solid connection from the motor to the diamond drive plate. This design produces far superior torque (vs. a belt-driven planetary system) while only drawing 14.9 amps
- Belts & Pulleys: used in planetary grinders to increase their RPM speed (for polishing). Torque, however, is greatly diminished which is required for grinding and removal. To off-set the reduced torque, planetary grinders rely on extreme weight to grind concrete and remove coatings.

Diamond Driver Plate

Equipped with 12-slots for diamond tools:
- (6) 3" Round - for 3" diamond tooling (metals, semi-metals, resins)
- (6) Trapezoid - for trapezoid style metal tooling
Counter-rotating plate for ergonomically balance, ease-of-use and minimal learning curve.
Plate accepts the complete assortment of tooling (shown below) for grinding, coating removal, polishing, scarify.


100% USA Manufacturing CNC Precision Made		Included insert blanks for recessed slots not being used.	Plate accepts Metal Diamonds, PCD's, Resin Pads, Carbide Scrapers.

Made of heavy, 3/8" steel-thick plate, powder-coated for corrosion resistance and easy cleaning
Damping isolators built-in to reduce vibrations and provide flex over high points and lippage
3" round diamonds and trapezoid tools are held securely in place by milled recesses and industrial magnets - tools are easy to change
Steel insert blanks (round and trapezoid) are included, fits into the unused recesses to prevent the openings from filling with debris
Plate attaches to the F75 with the industry standard NP9200 Clutch Plate for easy attachment to the grinder's 3-tab driver. Clutch helps to prevent damage to the grinder, diamond driver plate and bodily injury should the plate hit an obstruction on the floor.
