Description
Wandering plasma torches warp sheet panels and create time-consuming edge grinding chores on food-grade stainless tanks. The Fein Sheet Metal Shear up to twelve-gauge cold-rolled steel shears continuous sheet ribbons with zero plate distortion. A 350-watt electric motor delivers 1600 strokes per minute. Forcing this hand shear through heavy plate exceeding sixteen-gauge stainless steel stalls the reciprocating drive.
Die-cast aluminum gear cases house a precision eccentric drive mechanism supported by dual needle roller bearings. The reciprocating upper blade pairs with a fixed four-sided lower cutter blade machined from cryogenically treated AISI D2 tool steel. Pure copper commutator bars and resin-bonded rotor windings withstand high electrical heat during continuous industrial sheet production. Surface-hardened alloy rocker arms transfer motor rotation into clean vertical scissor strokes.
Sheet Metal Shear Performance Matrix
Continuous scissor action shears straight runs and wide radius profiles without panel warpage. Low blade clearance settings prevent razor burr formation along polished metal edges.
- 12-gauge mild steel cutting capacity handles thick ductwork panels and machinery guard fabrications
- 16-gauge stainless steel capability cuts commercial kitchen cladding without surface burn marks
- 350-watt motor unit maintains reciprocating blade speed under heavy operator hand feed
- 1600 strokes per minute stroke frequency delivers smooth metal separation rates on sheet stock
- Four-sided indexable lower blade rotates to expose fresh sharp edges before replacement needs
- Slim barrel motor housing gives operators positive grip control during intricate sheet profiling
- Integrated chip deflector shoe guides metal waste curling away from operator hand knuckles
Dyno Bench Load Telemetry
Bench telemetry records motor power and current demand through heavy sheet materials. The 120-volt motor pulls 1.4 amperes unloaded, rising to 3.2 amperes while slicing twelve-gauge cold-rolled carbon steel. Stroke rates dip from 1600 SPM free speed down to 1320 SPM under aggressive feed force. Decibel sound level meters read 80 dBA at operator ear level. Drive gearbox surface temperatures stabilize at 112 degrees Fahrenheit after shearing thirty feet of twelve-gauge stock.
Field Service Trade-Offs And Filters
Pushing this shear through heavy welded seams or multiple metal layers jams the reciprocating jaw. Demolition workers cutting corrugated roofing sheets should use punch nibblers instead of this shear. Never run this machine with loose blade gap clearance screws.
- Check blade gap clearances using feeler gauges before every production run.
- Rotate four-sided lower cutting blades when edges show dull or rounded corners.
- Blow metal grit out of motor intake slots with clean compressed air every week.
Factory Warranty And Case Components
Fein protects this commercial shear with a 3-Year limited warranty upon product registration. The package includes the electric sheet shear, one upper blade, one four-sided lower blade, thickness feeler gauge, hex wrench, and heavy carrying case.
