Description
Manual rebar cutters twist hands and cause operator shoulder strain on high-volume foundation pours. The BN Products 8 Portable Rebar cutter shears Grade 60 steel reinforcement rod up to one-inch diameter in five seconds. The hydraulic pump delivers thirty tons of shearing force. Do not expect this tool to cut high-tensile wire rope without fracturing blades.
Forged chrome-vanadium tool steel blocks house the heavy-duty hydraulic piston cylinder. Induction-hardened AISI S7 shock-resisting tool steel cutting blocks resist surface spalling under 45,000 PSI contact pressures. The pump drive features cold-forged eccentric shafts and copper alloy sleeve bearings that absorb mechanical shock from sudden metal fracture. High-pressure internal relief valves vent overpressurized oil backward when rebar exceeds rated diameter specifications.
Heavy Rebar Cutter Hardware Specs
Precision hydraulic ram geometry delivers square cuts without burrs or bent rod tips. Heavy return springs pull cutting anvils back the instant line pressure drops.
- 1.0-inch cutting capacity cleaves number eight Grade 60 rebar with zero mechanical hesitation
- 30-ton hydraulic thrust ram exerts massive shearing pressure through induction-hardened blades
- 5.0-second cutting stroke cycle speeds heavy steel reinforcement prefabrication on slab sites
- 12-ampere 115-volt electric motor spins the heavy eccentric piston pump mechanism
- Four-sided S7 tool steel blades rotate to expose fresh cutting surfaces before replacement
- Air purge valve vents internal hydraulic fluid cavitation bubbles on hot work sites
- Ductile cast iron cutter head withstands extreme impact stress without structural metal fatigue
Dyno Shear Force Benchmarking
Bench tests measure physical motor power and hydraulic pressure peaks during cutting strokes. Free-run current draw holds at 3.6 amperes, but spikes to 12.4 amperes during final steel fracture. Electrical line drop below 108 volts causes pump stall on Grade 60 rebar. Hydraulic line pressure builds to 9200 PSI within 3.8 seconds of trigger engagement. Acoustic output registers 85 dBA during active metal shearing cycles. Hydraulic reservoir temperature rises to 142 degrees Fahrenheit during sustained cutting runs.
Field Service Operational Traps
Hydraulic seal friction builds heat when operators exceed recommended duty cycles. Hand crews cutting fence wire or round aluminum tubing should avoid this specialized hydraulic shear. Running this unit without fresh hydraulic oil destroys internal pump pistons.
- Change hydraulic fluid using ISO VG 46 anti-wear oil every six months.
- Rotate four-sided cutting blocks before cutting edges show visible chipping or rounding.
- Tighten cutter block mounting bolts with thread locking compound after heavy use.
Commercial Warranty Package Inventory
