Description
Dull shears twist sheet panels into warped metal scrap that fails precision HVAC fitting standards. The Fein Cordless Slitting Shears Kit slices through sixteen-gauge mild steel sheet without surface scratches or panel distortion. An 18-volt brushless motor delivers 2200 to 3500 strokes per minute. Forcing this slitting tool into welded structural seams will snap the reciprocating center blade.
Die-cast aluminum gear housings protect a precision eccentric drive system supported by dual needle roller bearings. The drive converts motor rotation into rapid scissor strokes using high-tensile alloy steel rockers. Cryogenically treated AISI D2 tool steel forms both the reciprocating center cutter and dual stationary side blades. The brushless motor wet-end incorporates neodymium magnetic rotors and sealed ball bearings that block conductive metal swarf from settling inside electrical windings.
Cordless Slitting Shear Specs
Curled waste chips roll out through dedicated guide slots to prevent sheet surface scratches. The slim barrel grip gives technicians positive steering control across long sheet metal panels.
- 16-gauge mild steel cutting capacity produces smooth edge seams without plate distortion
- 18-gauge stainless steel capability cuts kitchen exhaust ductwork without edge discoloration
- Brushless 18-volt motor platform maintains reciprocating blade speed under heavy operator hand feed
- Variable stroke speed control selects 2200 to 3500 strokes per minute for various metal alloys
- Single continuous curled chip curls away from sheet surfaces to preserve protective paint coatings
- Reversible D2 tool steel cutter blades provide double edge life before replacement cycles
- Electronic cell protection blocks battery pack overload during aggressive sheet feed motions
Electrical Power Bench Diagnostics
Bench instruments record battery power consumption and motor speed across cold-rolled sheet metal. Unloaded motor rotation draws 1.8 amperes from the 18-volt battery pack, rising to 13.6 amperes during sixteen-gauge steel cuts. Stroke rates drop from 3500 SPM down to 2950 SPM under maximum feed pressure. Decibel sound level meters read 78 dBA at operator ear level. Gearbox casing temperatures climb sixteen degrees Fahrenheit after shearing forty feet of sheet metal.
Field Service Operational Traps
Attempting to cut multiple sheet layers or standing seams jams the reciprocating center blade. Ironworkers cutting heavy steel plate must use plasma cutters or band saws instead. Never adjust cutting blade clearances without disconnecting the lithium battery pack.
- Clear curled waste metal chips from the cutter head using pliers after long cuts.
- Lubricate blade sliding tracks with thin cutting oil every four operating hours.
- Check blade clearance settings using feeler gauges when changing material sheet gauges.
