Hawk F75 Concrete Floor Grinder | Surface Preparation & Coating Removal

Hawk F75 Concrete Floor Grinders

High-Torque Direct-Drive Grinder for Concrete Surface
Preparation, Coating Removal & Polishing

Hawk Concrete Floor Grinder - made in USA.

Hawk concrete grinders are direct-drive, single or dual-head surface prep machines built for aggressive coating removal, surface grinding and polishing.

Available in 17" and 20" models

Versus a planetary grinder which requires large power circuits and heavy weight

The Hawk F75 solves this.

High Torque Grinding

Direct-Drive gear system produces powerful torque to quickly remove:

Epoxy coatings, sealers, mastics, adhesives
Without tripping breakers

Versus the planetary grinders that require large power circuits and heavy weight

Runs on Standard
120V, 15-Amp Power

Operates on 120V power, making it ideal for restoration projects and interior work.

Heavy-Duty Design:

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. belt-drive) while only drawing 14.9 amps
- Belts & Pulleys: used in planetary grinders to increase their RPM speed (for polishing). However, torque 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.

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. Automatic and self-adjusting, scraps and dig-ins to the floor are prevented --- in complete contrast, 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
2-PIECE DESIGN: 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.

Additional Equipment --- Included & Optional

Included: Diamond Driver Plate

Counter-rotating for ergonomically balance, ease-of-use and minimal learning curve.
Plate accepts the complete assortment of tooling (shown below) for grinding, coating removal, polishing, and to 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.

Diamond Driver Plate includes the NP9200 Clutch Plate for easy attachment to the grinder's 3-tab driver.

PLATE FEATURES:

NP9200 Clutch Plate - the industry standard. Use to prevent bodily injury and damage to the diamond driver plate and grinder
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 standard size trapezoid tools are held securely in place by milled recesses and industrial magnets - tools are easy to change
Plate includes steel blanks, round and trapezoid, that fit in the unused recesses to prevent the unused openings from filling with debris.

Planetary Plate - Increases RPM Speed for Concrete & Stone Polishing

Increases driver speed from 165 to 400 RPM:
- Diamond driver plate (included with the grinder) & the planetary plant spin @ 165 RPM
- Six (6) individual pedestal heads (holds 3" diamond pads) spin @ 400 RPM each
Pedestal heads accept 3" round, semi-metal and 100% resin polishing pads
Planetary plate is equipped with its own metal clutch plate (see pic, left) - easy to install, removal and protects the plate and grinder
Pedestal heads with hook’n loop facing to securely hold the 3" round diamond pads
