Description
Abrasive chop saws generate shower sparks that trigger fire alarms and pose safety hazards in concrete precast plants. The Makita 18V LXT Lithium-Ion Cordless rebar cutter shears grade 60 steel rod up to 3/4-inch diameter in three seconds. A cold-shearing hydraulic ram cuts steel rod with zero hot sparks. Pushing structural alloy steel exceeding grade 60 ratings will chip cutting blades.
The hydraulic powerhead features a precision radial piston pump driven by a heavy-duty electric motor. CNC-ground AISI S7 shock-resisting tool steel cutting blocks provide four usable edges to resist impact fracture under high shear stress. The forged cutter head rotates 360 degrees on a heavy bearing collar to reach awkward rebar mat corners. Sintered bronze eccentric shaft bushings shed frictional heat under repetitive cycle sequences.
Cordless Rebar Cutter Hardware Specs
Two-way adjustable guide stops hold rebar square to the cutting blades to prevent rod twisting. Pistol grip configurations distribute weight cleanly across operator hands during flat slab cuts.
- 0.75-inch rebar capacity shears up to number six Grade 60 steel reinforcement bar effortlessly
- 3.0-second cutting stroke rate speeds repetitive rebar fabrication cycles on work sites
- 360-degree rotating cutter head provides convenient access between dense rebar grids
- Four-sided S7 tool steel blades rotate to provide fresh cutting edges before replacement
- Spark-free cold cutting action allows safe operation inside active chemical and industrial plants
- Adjustable stopper bolt stabilizes different rebar diameters perpendicular to cutting jaws
- High-pressure hydraulic relief valve bypasses oil flow if material hardness limits are exceeded
Hydraulic Dyno Load Telemetry
Bench testing evaluates battery current and hydraulic ram pressure throughout rebar severance. Running unloaded, the 18-volt motor draws 3.2 amperes, surging to 22.8 amperes as the cutting edge shears number six rebar. Pack terminal voltage drops to 16.1 volts during maximum hydraulic pressure spikes. Internal fluid pressure builds to 8500 PSI over a 2.8-second compression curve. Sound meters capture 78 dBA during cutting cycles. Hydraulic pump bodies experience an eighteen-degree Fahrenheit rise after twenty cuts.
Field Service Boundaries And Traps
Cutting case-hardened alloy bolts or leaf spring steel fractures the induction-hardened blade blocks. Structural ironworkers cutting large steel beam sections must use oxy-fuel or band saws instead. Never run the tool with loose blade mounting screws.
- Inspect cutter block bolts for proper tightness before every morning shift.
- Rotate four-sided cutting blocks when cutting edges show visible dulling or spalling.
- Wipe concrete grit and dirt off the hydraulic ram cylinder wiper seal weekly.
Commercial Warranty And Carton Contents
