Most home garages and small shops don't need a truck balancer — they need a machine that plugs into a standard outlet, handles everything from a 13" steel spare to a 22" alloy, and reads within a gram so the weight goes on once, not three times. That's the job the Katool KT-B700 is built for: a computer wheel balancer that takes rims under 30" and wheels up to 143 lbs, spins a measurement in 7 seconds, and runs on ordinary 110V single-phase power — no special wiring, no shop air. Build and Accuracy 3 mm steel cabinet, solid-welded — the extra plate thickness keeps vibration out of the measurement instead of into it. One-piece pressure-sensor mount on 8 mm plate — the sensor assembly sits on 8 mm bottom and side boards, so the load cells read the wheel, not cabinet flex. That's where the ±1 g accuracy comes from. Copper-wound motor — pure copper windings for faster heat dissipation and longer service life. Quench-hardened 36 mm shaft, 270 mm long — the longer shaft takes wider wheels, and the removable threaded stud lets you replace the arbor rather than the machine if it's ever damaged. Sealed electronics — the computer board is moisture-proof, dust-proof and anti-static; the display is easy-read LED with separate inner/outer weight readouts. Grams or ounces, millimeters or inches — switch units from the keypad. Optional wheel guard available for added safety. Five Balance Modes Plus Weight Optimization The KT-B700 powers up in dynamic mode and covers the weight placements a mixed bay actually sees: Dynamic — clip-on weights both sides; standard steel and alloy wheels. Static — one hidden stick-on weight in the center plane. ALU1 / ALU2 / ALU3 — stick-on and mixed placements for aluminum rims, including hidden-weight positions that keep the outer face of a polished wheel clean. OPT weight optimization — when a wheel calls for more than 30 g of correction, OPT walks you through rotating the tire on the rim to cancel imbalance instead of stacking weight. Katool's manual shows a 45 g correction dropping to 9 g. Built-in fault diagnosis and a self-calibration routine use the included 100 g calibration weight — the machine arrives factory-calibrated, and you can re-verify it yourself with any 13"–14" wheel rather than waiting on a service call. What's Included Four centering cones (No. 1–No. 4) with back cone spring and balance bowl Quick-release wing nut Rim width calipers Wheel weight hammer 100 g calibration weight Operation manual The KT-B700 is also sold paired with Katool's tire changers — the KT-T800 + KT-B700 combo and the KT-T835 + KT-B700 combo outfit a complete tire station in one order. Specifications Rim diameter Under 30" Rim width 3" – 12" Max wheel diameter 880 mm (34.6") Max wheel weight 143 lbs (65 kg) Rim center hole diameter Under 135 mm (5.31") Balancing accuracy ±1 g Measuring time 7 seconds Balancing speed 180 rpm Shaft 36 mm diameter, 270 mm long, removable stud Motor 0.25 kW Power supply 110V single-phase Power and Installation Standard outlet: 110V single-phase on a grounded three-pin outlet — the ground circuit matters (under 1 ohm to building ground); a defective ground is a shock hazard and voids the warranty. When in doubt, have an electrician verify the outlet. Floor: solid, flat concrete. In normal service the balancer bolts to the floor through its three support feet; most electrical codes call for hard wiring on a bolted-down install, so plan the spot before anchoring. Clearance: leave working room around the machine for mounting and demounting wheels — the footprint itself is compact enough for a single bay corner. Safety interlock: the spin cycle runs hood-down; the interlock should never be bypassed. Warranty Katool covers the KT-B700 with a limited one-year (12-month) parts warranty against product defects — including motors, displays and electronics — with replacement parts shipped free. A 2-year extended warranty plan is available for any Katool or M&E automotive equipment. Claims require the original order number and purchase from My Garage Supplies or a registered vendor; labor is not included, and warranty service is subject to approval by Katool's service department.
