Description
Hot abrasive spark showers and jagged slag burrs create severe workplace fire risks and slow down structural pipe welding. The Makita 12 In. Metal Cutting saw produces clean cold cuts through steel pipe and angle iron without open flame sparks. High-torque cermet blades cost four times more than abrasive discs, punishing operators who force downfeed cuts too fast.
A fifteen-amp electric motor delivers high torque through heat-treated alloy steel gearing housed in a rigid cast aluminum gear case. The one-inch arbor turns inside sealed ball bearings that resist fine iron swarf intrusion. A spring-loaded chip tray catches hot metal shavings beneath the cast iron base, while a quick-release manual screw vise clamps structural steel shapes without slippage during heavy cutting loads.
Cold Metal Chop Hardware Specifications
Structural metal fabrication shops demand dead-square cuts across steel tubing and pipe without hazardous spark plumes. Low-speed high-torque cold cutting preserves metal temper without creating heat-affected zones.
- 15-amp electric motor spins 12-inch cermet blades at 1300 RPM for burr-free cold metal sectioning
- 12-inch cermet-tipped blade slices four-inch steel pipe and 4-1/2-inch angle iron without sparks
- Removable chip collection tray catches hot metal shavings to maintain clean shop air
- Quick-release manual vise clamps structural stock tight and features an adjustable angle guide
- Cast aluminum base plate resists jobsite drop impacts while providing steady flat cutting support
- Spindle lock button holds the drive arbor stationary for rapid blade swaps using a single hex tool
- Heavy-duty motor brushes feature external access caps to speed up inspection during service teardowns
Bench Load Telemetry Amperage Draw
Motor draw settles at 5.2 amps during free-spin operation on standard 120-volt utility circuits. Slicing through three-inch schedule 40 structural steel pipe brings current draw to 14.6 amps while maintaining steady blade momentum. Workpiece edge temperatures remain under 125 degrees Fahrenheit, allowing immediate hand contact without heat gloves. Sound output reaches 89 dBA under load, requiring operator hearing protection.
Field Service Trade-Offs Application Filter
Do not use this cold chop saw for slicing masonry brick, concrete board, or wood timbers with embedded dirt. Inexperienced operators who slam the plunge handle down chip brittle cermet blade teeth on solid steel bar. Empty the swarf collection tray after every six cuts to prevent hot chip backup into the lower guard. Inspect carbon motor brushes every sixty operating hours for uniform contact wear. Blow metal filings out of the motor vents with dry shop air.
Warranty Protection Standard Package Items
A 1-Year limited warranty covers mechanical gear parts and motor windings under commercial use. The package includes the 12-inch metal cutting saw, 60-tooth cermet-tipped blade, socket wrench, safety goggles, and operating instructions.
