Description
Heavy-duty reduction gearboxes convert three horsepower of electric current into six inches of plunge cut depth on the Diamond Products C16 Electric Hand Saw. This sixteen-inch handheld saw cuts reinforced concrete walls and slabs without exhaust fumes. An overload-protected motor drives the spindle. You must connect this saw to a dedicated twenty-amp 120-volt circuit.
Diamond Products encases the reduction gearing in a cast magnesium gear case mated to an impact-resistant composite motor shell. The 15-amp 120V electric motor delivers 3.0 HP, driving the one-inch arbor at 2600 RPM through oil-bath steel helical gears. Machine weight totals 26.5 lbs without blade. Exterior dimensions measure 28 inches long by 11 inches wide by 16 inches high with an adjustable magnesium guard.
Key Features of Diamond Products C16
Basement egress contractors buy Diamond Products C16 electric saws to saw structural foundation walls while checking commercial tool pricing. Demolition crews cut concrete floor slabs and thick brick veneers inside occupied homes without setting up auxiliary gas exhaust venting systems.
- Powerful 15-amp motor delivers zero emissions for safe cutting inside finished commercial basements.
- Sixteen-inch blade guard clears full six-inch plunge cut depths in reinforced concrete and brick.
- Oil-bath gear reduction case runs cool under sustained full-depth cutting drag.
- Integrated water feed manifold with regulator valve delivers moisture to suppress silica dust.
- Electronic soft-start and thermal overload protection prevent sudden breaker trips on jobsite panels.
- Detachable guide rollers on the base plate help operators maintain straight tracking across slabs.
- Ergonomic D-handle with rubber grip zones provides balanced control for horizontal and vertical cuts.
Helical Gearbox Arbor Runout Tolerances
Bench testing on the one-inch turned and ground blade arbor confirms precision mechanical concentricity. Arbor runout measures under 0.0009 inches TIR at the blade mounting face. Under continuous six-inch plunge cuts through four-thousand-PSI limestone concrete, the 15-amp motor draws 14.8 amps, maintaining 2350 blade RPM without thermal cutouts. Oil-bath gear head casing temperatures stabilize at 138 degrees Fahrenheit after forty minutes of steady slab sawing. The mechanical slip clutch slips reliably at thirty-four foot-pounds of sudden blade bind torque.
Indoor Slab Cutting Maintenance Scope
Pushing this 26.5-pound electric cutter along floor slabs feels controlled thanks to detachable base guide rollers, though horizontal wall cuts demand firm two-hand shoulder support. The trigger switch seals tight against airborne concrete dust. Do not buy this corded saw for remote outdoor highway work lacking electrical generator power drops.
- Blow dry concrete dust out of the motor air vents after every work shift.
- Inspect the carbon motor brushes for wear every eighty operating hours.
- Flush the water delivery tubes with clean tap water after finishing wet cuts.
