Description
Dragging tangled cords through puddle-strewn steel erection sites creates severe electrical shock hazards during structural framing. The Makita 40V max XGT 7 1/4in Metal cutting saw kit delivers cold metal slicing mobility via a 40-volt brushless motor and 4.0 Ah battery pack. High-feed cuts through thick structural plate drain single battery packs fast, demanding multiple charged batteries during all-day steel fabrication shifts.
A brushless DC motor mounts inside a rigid cast aluminum gear case, utilizing high-temperature neodymium magnets to maintain rotational torque under load. Hardened alloy steel spur gears transmit power to the 5/8-inch arbor, supported by sealed ball bearings that stop fine metal swarf intrusion. A heavy stainless steel base plate resists gouging on sharp metal edges, while an electronic motor brake halts blade momentum within seconds of trigger release.
Cordless Metal Cutting Hardware Matrix
Commercial metal framing crews demand spark-free cold cuts on structural steel studs, conduit, and threaded rods. Stainless steel guide shoes glide smooth across corrugated metal decking without marring finishes.
- 40-volt brushless motor delivers 3500 RPM to section structural steel, iron pipe, and metal studs
- 7-1/4-inch cermet-tipped blade slices steel plate up to 1/4 inch thick without producing thermal burrs
- Integrated chip collector chamber traps hot swarf to maintain clean shop air and prevent burns
- Electronic blade brake halts rotational momentum within two seconds to maximize jobsite safety
- Stainless steel base plate glides smooth over metal decking without gouging galvanized coatings
- 4.0 Ah high-output battery pack supplies high current discharge through low-resistance cell welds
- Rapid battery charger restores full operational charge to depleted 4.0 Ah packs in under forty-five minutes
Bench Load Telemetry Amperage Draw
Under free-spin rotation, the brushless motor pulls 2.8 amps DC from the 40-volt platform. Slicing through 1/4-inch solid structural steel plate brings battery discharge current up to 26.4 amps while blade velocity holds at 3180 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 cermet 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. Store lithium batteries inside heated jobsite tool trailers.
Warranty Protection Standard Package Items
A 3-Year limited warranty covers the metal cutting saw, 4.0 Ah battery, and rapid charger. The kit box contains the 7-1/4-inch metal cutting saw, one 4.0 Ah battery pack, rapid charger, cermet blade, hex wrench, and contractor tool bag.
