Description
Burred pipe ends and heat-affected zones create weld contamination when cutting structural tubing with dry abrasive chop saws. The JET CS-275 MANUAL COLDSAW produces clean square cuts on carbon steel using low-speed high-torque cutting actions. Slow cycle speeds frustrate operators accustomed to high-speed dry abrasive chops, while incorrect coolant ratios ruin expensive high-speed steel blades.
A heavy cast iron saw head pivots on hardened steel trunnion pins, damping vibrations that cause high-speed steel tooth fractures. The electric motor drives a case-hardened alloy steel worm shaft paired with a centrifugally cast bronze worm wheel inside an oil-bath gearbox. Flood coolant lines route lubrication through an internal diaphragm pump directly onto the blade face, flushing metallic chips out of the cut kerf to prolong cutting edge life.
Cold Cutting Matrix Mechanical Attributes
Pipe fabrication demands mill-finish square cuts without thermal distortion or heavy flash burrs. Manual downfeed levers translate human feed pressure into uniform chip loads across tube profiles.
- 1.5 HP dual-voltage electric motor provides balanced power for tough carbon steel sectioning
- Two-speed gearbox shifts between 54 and 108 RPM to match surface speed across steel alloys
- 275 mm high-speed steel circular blade slices thin wall tubing without thermal perimeter stress
- Manual clamping vise secures workpieces on both sides of the blade to stop cutoff drops
- Internal mechanical diaphragm pump floods cutting fluid across tooth tips during the stroke
- Miter head rotates forty-five degrees left and right with positive detent lock points
- Cast iron base sump stores coolant and collects heavy steel swarf settling below the pump
Bench Load Telemetry Amperage Draw
Motor load draws 3.2 amps at idle on 230-volt three-phase power settings. Plunging a 275 mm 120-tooth blade through two-inch schedule 40 carbon steel pipe at 54 RPM elevates current draw to 5.4 amps. Worm gear oil sump temperature rises from 68 degrees to 118 degrees Fahrenheit after two hours of cycling. Noise levels remain exceptionally low at 72 dBA, eliminating ear fatigue in indoor pipe fabrication shops.
Field Service Trade-Offs Application Filter
Do not use this machine to cut hardened tool steels or non-ferrous aluminum extrusions at low speeds. Operators forcing the hand feed lever chip brittle high-speed steel teeth on thin conduit. Clean magnetic swarf traps in the coolant reservoir at the conclusion of each shift. Check bronze worm gear backlash using a dial indicator every six months. Replace gearbox mineral oil after every five hundred operating hours to prevent bronze tooth wear.
Warranty Protection Standard Package Items
A 2-Year limited warranty protects against manufacturing defects and gearbox failures. Delivery includes the cold saw unit, floor pedestal stand, flood coolant pump, dual-clamping vise, material stop rod, operator splash shield, and mechanical service tool kit.
