Description
Airborne silica dust clouds trigger OSHA fines and pose severe respiratory health hazards during commercial concrete drilling. The Makita 18V X2 (36V) LXT 1-1/8in AVT Rotary Hammer with Dust Extractor AWS bare tool captures concrete dust directly at the hole collar. Twin 18-volt batteries power a brushless motor delivering 3.2 foot-pounds of impact energy. Pushing bits beyond 1-1/8-inch solid diameter limits stalls the drive.
Die-cast aluminum gearcases house an air-cushioned hammer mechanism supported by cylindrical roller bearings. Anti-Vibration Technology utilizes an internal counterbalance system that moves opposite the drive piston to cancel mechanical recoil. The HEPA dust extractor mounts directly onto the hammer chassis, drawing vacuum power from an independent motor. Auto-start Wireless System modules activate paired shop vacuums via Bluetooth the instant the drill trigger is pulled.
AVT Rotary Hammer Hardware Specs
Integrated HEPA vacuum attachments capture airborne silica dust to meet OSHA Table 1 compliance. Internal mechanical counterbalances cancel striker vibration before it reaches operator hand grips.
- 1.125-inch drilling capacity cuts commercial structural anchor holes in reinforced slabs
- 3.2 foot-pounds of impact energy shatters high-strength concrete aggregate effortlessly
- Twin 18-volt battery configuration delivers 36-volt power across high-demand drilling runs
- Anti-Vibration Technology counterbalances cancel reciprocating shock inside the tool chassis
- Integrated HEPA dust extractor vacuums silica particles directly at the drill hole mouth
- Auto-start Wireless System pairs with jobsite vacuums via Bluetooth for cordless dust control
- SDS-plus tool chuck permits rapid bit changes with single-hand pull-back collars
Hammer Dyno Bench Readings
Bench power analyzers track electrical current draw and impact energy across high-strength cured concrete. Running unloaded, the twin 18-volt pack draws 3.1 amperes, climbing to 28.4 amperes while driving a one-inch bit. Battery pack terminal voltage drops from 36.2 volts down to 31.4 volts under peak hammering resistance. Striker cadence hits 4500 BPM under active load. Sound level meters read 92 dBA at the operator position. Gearcase temperatures rise 26 degrees Fahrenheit after twenty holes.
Field Service Operational Traps
Clogged HEPA filters choke vacuum suction and allow toxic silica dust into the air. Interior drywall installers hanging light fixtures should use small twelve-volt drills instead. Never run the hammer without emptying full dust extractor canisters.
- Empty the dust extractor collection box before concrete powder reaches the fill line.
- Tap HEPA filter pleats clean over a trash bin after every twenty drilled holes.
- Grease SDS-plus bit shanks with high-pressure chisel lubricant before every work shift.
Commercial Warranty Package Inventory
