Description
Abrasive cutoff wheels burn galvanized coatings and leave warped sheet edges on architectural metal jobs. The Fein Slitting Shear up to sixteen-gauge steel cuts metal strips without surface distortion or chip waste. A 350-watt electric motor delivers 2100 to 4500 strokes per minute. Forcing this slitting tool into structural plate beyond eighteen-gauge stainless steel will snap cutter blades.
Die-cast aluminum gear housings protect high-precision eccentric drive shafts supported by needle bearings. The drive converts motor rotation into rapid linear strokes using surface-hardened alloy steel rockers. Cutting blades utilize high-carbon AISI D2 tool steel that maintains edge sharpness through abrasive zinc coatings. Solid motor commutator assemblies feature pure copper bars and high-temperature resin insulation that resists brush arc degradation.
Slitting Shear Performance Matrix
Twin stationary side blades support thin sheet surfaces while a center cutter shears clean kerf ribbons. The smooth guide table glides across polished metals without scratching.
- 16-gauge mild steel cutting capacity produces burr-free cuts without panel deformation
- 18-gauge stainless steel capacity handles industrial restaurant and laboratory sheet cladding
- 350-watt motor armature delivers sustained high-speed shearing strokes under continuous feed
- Variable stroke rate control dials adjust cuts between 2100 and 4500 strokes per minute
- Single continuous curled chip curls away from workpieces to preserve surface finishes
- Reversible D2 tool steel blades double operating life before blade replacement cycles
- Slim motor barrel grip reduces hand fatigue during continuous architectural profiling cuts
Dyno Bench Load Telemetry
Dyno testing quantifies motor current and speed retention under heavy sheet resistance. Free-stroke current measures 1.2 amperes at 120 volts, climbing to 2.9 amperes during 16-gauge cold-rolled steel severance. Stroke frequency drops from 4500 SPM free speed to 3800 SPM under maximum feed pressure. Sound pressure output measures 79 dBA at the operator ear. Gearbox temperatures rise 24 degrees Fahrenheit above ambient room levels during continuous ten-foot sheet cuts.
Field Application Traps And Rules
Feeding twisted seams or heavy lock joints into the blade slot jams the reciprocating center cutter. Ironworkers cutting heavy structural angle iron must use magnetic base drills or bandsaws instead. Never adjust blade clearances without unplugging the power cord.
- Clean curled scrap metal spirals out of the cutter head using needle-nose pliers.
- Lubricate cutter blade slide surfaces with light machine oil every four hours.
- Check blade gap clearances using feeler gauges whenever cutting different sheet gauges.
