Description
Traditional hand snips curl thin sheet edges and cause severe wrist tendonitis during long duct fabrication runs. The Fein Sheet Metal Shear up to sixteen-gauge steel cuts cold-rolled sheet without edge twisting or surface scratches. A 350-watt motor produces 2800 to 4700 strokes per minute. Forcing this hand shear into heavy steel plate exceeding sixteen-gauge thickness stalls the reciprocating drive.
Die-cast aluminum gear cases house a precision eccentric drive mechanism supported by dual needle roller bearings. High-tensile alloy steel rockers convert motor rotation into rapid vertical shear strokes. The cutting unit pairs an upper moving blade with a four-sided lower stationary blade machined from cryogenically treated AISI D2 tool steel. Copper commutator segments and high-temperature resin armature coatings protect the motor from electrical heat breakdown during continuous sheet profiling.
Sheet Metal Shear Performance Specs
Four-sided indexable lower blades provide four sharp shearing edges before replacement is required. The slim barrel grip gives technicians positive steering control across complex sheet curves.
- 16-gauge mild steel cutting capacity produces smooth edge seams without panel warpage
- 19-gauge stainless steel capability cuts kitchen cladding without edge discoloration or burrs
- 350-watt motor unit maintains reciprocating blade speed under heavy operator hand feed
- Variable speed dial adjusts stroke frequency between 2800 and 4700 strokes per minute
- Four-sided indexable lower blade rotates to expose fresh sharp edges before replacement needs
- Slim motor barrel housing provides secure single-handed steering across narrow sheet contours
- Integrated chip deflector shoe guides metal waste curling away from operator hand knuckles
Dyno Bench Load Telemetry
Dyno bench testing monitors motor current draw and speed stability under sheet metal friction. The 120-volt motor pulls 1.2 amperes running unloaded, rising to 2.8 amperes while slicing sixteen-gauge cold-rolled carbon steel. Stroke rates decrease from 4700 SPM free speed down to 3950 SPM under aggressive feed force. Decibel sound level meters read 79 dBA at operator ear level. Drive gearbox surface temperatures climb eighteen degrees Fahrenheit after shearing thirty feet of sixteen-gauge stock.
Field Service Operational Traps
Feeding double-lapped sheet seams into the blade slot jams the reciprocating upper cutter. Structural ironworkers cutting heavy angle iron must use cold cut saws or plasma torches instead. Never operate this shear with loose blade gap clamping screws.
- Check blade gap clearances using feeler gauges before starting heavy production shifts.
- Rotate four-sided lower cutting blades when edges show dull or rounded corners.
- Blow metal grit out of motor cooling vents with clean compressed air every week.
