Description
Thermal surface hardening and heavy perimeter burrs ruin structural weld joints when cutting carbon steel pipe with dry friction saws. The JET J-FK350-2K 350 mm Manual cold saw produces clean mill-finish cuts using low-speed high-torque rotation. Slow cycle times frustrate operators accustomed to high-speed abrasive saws, while running without flood coolant ruins expensive high-speed steel blades.
A massive cast iron saw head pivots on hardened steel trunnion pins, damping harmonics that break fragile high-speed steel saw teeth. The two-speed motor transfers high torque through a hardened steel worm shaft and centrifugally cast bronze worm wheel running inside an internal oil bath. A self-priming mechanical diaphragm pump delivers flood coolant directly to both sides of the 350 mm blade, flushing chips out of the cut kerf.
Ferrous Cold Saw Hardware Specifications
Structural pipe fabrication shops demand dead-square cuts without heat-affected zones or heavy perimeter slag burrs. Dual-clamping vises hold both sides of the workpiece to stop cut-off drop burrs and blade pinches.
- 2.5 HP electric motor operates on 230-volt single-phase power to section heavy structural alloy steels
- Two-speed gearbox provides 44 and 88 RPM options to match tooth surface speeds across tough alloys
- 350 mm high-speed steel blade capacity sections 4-1/2-inch round tube and 3-1/2-inch solid bar stock
- Dual manual clamping vise locks material on both sides of the blade to prevent cutoff whip burrs
- Flood coolant pump circulates cutting fluid through twin adjustable nozzles to maximize blade life
- Miter head rotates 45 degrees right and left with positive mechanical stops at common angles
- Heavy cast iron floor pedestal encloses the flood coolant reservoir tank and chip collection tray
Bench Load Telemetry Amperage Draw
The motor pulls 4.8 amps at idle on 230-volt line feeds. Sectioning three-inch solid 1045 steel bar at 44 RPM increases continuous current draw to 11.4 amps while blade speed holds steady. Bronze worm gear oil bath temperature stabilizes at 122 degrees Fahrenheit under continuous shop cycling. Acoustic output registers at 72 dBA, eliminating ear fatigue in enclosed structural fabrication shops.
Field Service Trade-Offs Application Filter
Do not use this low-speed machine to section thin non-ferrous aluminum extrusions or brittle plastic conduit. Operators who slam the manual downfeed lever chip expensive high-speed steel teeth on solid bar stock. Clean the magnetic chip collector in the coolant reservoir at the conclusion of each shift. Change the bronze gear oil after every five hundred operating hours. Inspect the vise screw brass nut for wear every six months.
Warranty Protection Standard Package Items
A 2-Year limited warranty protects the gearbox, motor, and cast iron frame against manufacturing defects. The delivery shipment contains the 350 mm cold saw unit, structural pedestal stand, flood coolant pump, dual-clamping vise, material stop gauge, and service tool set.
