BN Products Cordless Cutting Edge Saw Kit 20mm

Description

Abrasive cutoff wheels throw hot shower sparks that ruin architectural coatings and leave jagged rod burrs. The BN Products Cordless Cutting Edge saw kit 20mm slices rebar, steel pipe, and all-thread rod up to 3/4-inch diameter. A 24-volt brushless motor produces 2200 RPM for clean cuts. Pushing dull blades through high-tensile anchor bolts will trigger electronic thermal overloads.

Die-cast aluminum gear cases house precision spiral bevel gears running inside heavy synthetic grease. The brushless motor wet-end incorporates neodymium magnetic rotors and copper stator windings that shed thermal build under continuous feed friction. The drive arbor mounts inside rubber-sealed deep-groove ball bearings that stop concrete slurry intrusion. Tungsten-carbide-tipped blades spin behind a cast aluminum chip deflector that channels hot metal waste downward away from operator hands.

Flush Cutting Saw Hardware Specs

Flat housing profiles permit flush cutting along concrete walls, foundations, and floor slabs. Multi-position side handles balance tool weight during awkward horizontal cuts.

• 0.75-inch cutting capacity shears number six Grade 60 rebar and structural conduit flush
• 24-volt brushless motor delivers continuous rotational torque with low battery power drain
• 2200 RPM spindle speed maintains optimal tip speed for carbide cutting teeth
• Removable chip collection guard captures hot steel filings to protect finished floors
• Three-position auxiliary handle mounts to top or sides for tight corner access
• Cold-cutting carbide blade technology leaves burr-free cuts without burning zinc coatings
• Electronic overload protection system cuts power before motor windings experience thermal damage

Dyno Bench Load Telemetry

Bench testing monitors battery current draw and spindle speed under heavy metal resistance. Unloaded motor rotation draws 2.0 amperes from the 24-volt battery, surging to 16.8 amperes while cutting 0.75-inch Grade 60 steel rebar. Pack terminal voltage drops to 21.8 volts during maximum blade feed resistance. Spindle speed drops from 2200 RPM free speed down to 1820 RPM under heavy manual feed. Decibel sound level meters read 83 dBA at operator ear level. Gearbox casing temperatures climb twenty degrees Fahrenheit after ten cuts.

Field Service Operational Traps

Abrasive concrete dust packs behind blade guards if operators skip routine cleanings. Structural ironworkers cutting heavy I-beam flanges must use magnetic drills or torches instead. Never run this flush saw with missing blade collar screws.

• Clear metal shavings out of the blade guard cavity after every work shift.
• Check blade collar retaining screws for tight torque before starting cuts.
• Wipe battery connection pins with dry cloth wipes every forty run hours.
