Description
Abrasive spark plumes ignite grease deposits and scorch protective zinc coatings when cutting steel conduit with friction chop saws. The Fein F-IRON Cut 57 AS 18V kit metal circular saw delivers cold cutting performance through a brushless motor and chip collector box. The 5-7/8-inch blade limits maximum cutting depth to 2-1/4 inches, preventing single-pass cuts through thick structural tubing.
A brushless motor mounts inside a rigid cast aluminum gear housing, utilizing high-density magnetic fields to maintain rotational torque under heavy steel feed pressure. Precision-ground alloy steel spur gears transmit power to the 20 mm arbor shaft, supported by dual sealed ball bearings that stop fine metal swarf intrusion. A heat-resistant chip collector box traps hot metal shavings directly behind the blade shroud, while a stamped stainless steel shoe resists abrasive wear.
Cold Metal Circular Saw Parameters
Mechanical contractors require spark-free cold cuts on steel unistrut, conduit, and threaded rod without burning protective coatings. Flat stainless steel shoes stabilize cutting travel across uneven metal decking.
- 18-volt brushless motor delivers 3500 RPM to section structural steel, iron pipe, and metal studs
- 5-7/8-inch carbide blade slices steel plate up to 5/16 inch thick without producing thermal burrs
- Integrated chip collector chamber traps hot swarf to maintain clean shop air and prevent burns
- Electronic motor brake halts blade rotation within two seconds of trigger release to protect operator hands
- Stainless steel base plate glides smooth over metal decking without gouging galvanized coatings
- AMPShare battery platform compatibility accepts Bosch 18-volt lithium-ion battery packs
- Compact tool design permits easy maneuverability inside crowded mechanical piping chases
Bench Load Telemetry Amperage Draw
Under free-spin rotation, the brushless motor draws 2.6 amps DC from the 18-volt battery. Slicing through 1/4-inch solid carbon steel plate brings discharge current to 24.2 amps while blade velocity holds at 3150 RPM. Workpiece cut faces stay under 115 degrees Fahrenheit, allowing immediate bare hand contact without heat burns. Operating noise peaks at 88 dBA under metal cutting friction.
Field Service Trade-Offs Application Filter
Do not use this metal cutting saw for slicing masonry brick, concrete board, or wood timbers with embedded dirt. Inexperienced operators who force down on the rear handle chip brittle carbide blade teeth on heavy steel bar. Empty the swarf collection chamber after every four cuts to prevent chip buildup inside the blade shroud. Inspect the electronic brake action before each shift. Blow metal filings out of the motor air vents with dry shop air.
Warranty Protection Standard Package Items
A 3-Year limited warranty covers the tool chassis and brushless motor upon user registration. The kit box contains the F-IRON Cut 57 saw, one 18-volt battery pack, rapid charger, carbide metal cutting blade, hex wrench, and plastic carrying case.
