Description
Trailing extension cords trip finish carpenters and drop motor voltage when trimming interior casings far from panel boxes. The Makita 40V Max XGT Brushless 8-1/2-inch sliding miter saw bundle delivers corded cutting capacity on a compact folding stand. Compact 8-1/2-inch blade diameters restrict vertical cut height, requiring operators to lay tall crown moldings flat on the table.
A brushless DC motor mounts on a cast aluminum arm, drawing 40 volts DC from an XGT battery through digital control circuits. Dual linear ball bearings slide along forward-facing fixed steel guide rails, permitting flush placement against shop walls without rear rail clearance issues. Cast aluminum table components incorporate CNC-machined miter detent plates that maintain positive lock locations at standard trim angles.
Forward Rail Cordless Miter Metrics
Finish carpenters trimming interior window casings require light transport mass combined with hair-line cut accuracy. Forward rail configurations permit placement directly against finished drywall inside tight rooms.
- 40-volt brushless motor delivers 4800 RPM to make crisp chip-free cuts in brittle oak and pine trim
- Forward rail configuration permits placement directly against rear walls without clearance interference
- Dual bevel capacity reaches 48 degrees left and right with up-front thumb-latch bevel detents
- 8-1/2-inch carbide blade cuts 2-13/16-inch vertical baseboard and twelve-inch flat shelving stock
- Integrated shadow cut line projection unit casts an exact blade kerf shadow across workpieces
- Machined aluminum base table features positive miter detents at standard trim angles for rapid setups
- Folding jobsite stand provides sturdy tubular beam support with extendable material roller wings
Bench Load Telemetry Amperage Draw
Under free-spin rotation, the brushless motor draws 2.6 amps DC from the 40-volt platform. Crosscutting eight-inch wide laminated oak stair treads increases battery discharge current to 28.5 amps while motor speed dips from 4800 RPM down to 4390 RPM. Rail deflection tests under 0.001 inches under crosscut downforce. Acoustic emissions measure 86 dBA under load, staying within normal construction ear limits.
Field Service Trade-Offs Application Filter
Do not use this machine to cut wet structural green timbers or non-ferrous metals without proper coolants. Workers who slam the forward carriage into the rear travel stops fracture the aluminum bearing housings. Clear accumulated sawdust from the sliding rail wiper seals using dry compressed air. Verify miter detent zero alignment with an engineer square every fifty cutting hours. Store lithium batteries inside climate-controlled work vans during freezing winter nights.
Warranty Protection Standard Package Items
A 3-Year limited warranty protects the cordless saw, folding stand, battery, and charger against factory defects. The kit bundle contains the miter saw, folding stand with rollers, 4.0 Ah battery, rapid charger, carbide blade, clamp, and dust bag.
