Makita 40V Max XGT Brushless Lithium-Ion 4-1/2 in./5 in. Cordless Paddle Switch Angle Grinder Kit with Electric Brake (4 Ah) - GAG03M1

Makita 40V Max XGT Brushless Lithium-Ion 4-1/2 in./5 in. Cordless Paddle Switch Angle Grinder Kit with Electric Brake (4 Ah) - GAG03M1 

The 40V max XGT Brushless Cordless 4-1/2" / 5” Paddle Switch Angle Grinder Kit with Electric Brake (GAG03M1) delivers corded grinding performance without the cord for the most demanding applications. It's powered by a Makita-built brushless motor which delivers 8,500 RPM for heavy-load applications and increased power and speed. The GAG03M1 offers up to 60% faster cutting speed when cutting #5 (5/8”) rebar. It is ideal for grinding and cutting a wide range of materials including tile, concrete, pipe, conduit, and more.

An electric current limiter helps protect the motor from overload in high-torque applications. Additional features include an electric brake that stops the grinding or cut-off wheel in 2 seconds or less and Active Feedback-sensing Technology (AFT®) that turns the motor off if rotation of the wheel is forced to a stop.

What our Experts Think

• Contractor‑Grade Suction: Powerful 12 AMP motor delivers up to 148 CFM airflow and 92″ water lift — strong enough for concrete, wood, and general jobsite cleanup.

• Premium HEPA Filtration: Certified HEPA filter traps 99.97 % of particles ≥0.3 µm, with a multi‑stage system to extend filter life and boost efficiency.

• Smart Operation: On‑board tool‑activated outlet automatically starts/stops with connected power tools — improving workflow and reducing wasted runtime.

• Quiet & Mobile: Sound‑absorbing motor chamber runs at about 60 dB(A), while wide wheels and steel casters add stability and easy movement.

• Auto Filter Cleaning: Reversing airflow gently knocks off buildup to maintain suction and extend filter life.

• Job‑Ready Accessories: Includes long anti‑static hose and multiple adaptors for flexible connections.

Q: How large and portable is it?
A: 35 lbs dry weight, 24.6 ft cord, and 13 ft anti‑static hose for reach and mobility around the job site.

Maintenance Tips

• Empty & clean container regularly: Empty the dust/hazardous debris before it fills to capacity, and wipe the interior clean to preserve suction power.

• Clean or replace filters: Use the automatic filter‑cleaning system during dry use; periodically remove and gently clean or replace the HEPA and flat filters to maintain airflow and capture efficiency.

• Monitor wet pickup: When collecting liquids, turn off automatic filter cleaning, ensure water level limit systems work, and empty/clean the tank promptly to prevent sensor issues.

• Inspect hose & connections: Check the anti‑static hose, cuffs, and seals for blockages or wear; clear obstructions to maintain consistent suction.

• Keep cooling vents clear: Clean the cooling air diffusor and external vents to prevent dust build‑up around the motor and electronics.

• Store properly: After use, unplug, coil the power cord neatly, and store in a clean, dry area to prevent moisture or dust damage.
