Makita 18V X2 (36V) LXT Rotary Hammer 1 9/16in Advanced AVT SDS MAX AFT AWS (Bare Tool)

Description

Massive concrete coring bits shake hand-held tools violently and induce severe operator fatigue during high-volume commercial installations. The Makita 18V X2 (36V) LXT Rotary Hammer 1 9/16in Advanced AVT bare tool powers large carbide core bits through structural slabs without user fatigue. Dual 18-volt batteries drive a brushless motor delivering 8.4 foot-pounds of impact energy. Coring hard river rock without downforce trips electronic limiters.

Die-cast magnesium gear housings enclose an air-cushioned striker assembly supported by double-row cylindrical roller bearings. Anti-Vibration Technology incorporates an internal counterbalance system that reciprocates opposite the drive piston to cancel mechanical recoil. The brushless motor wet-end features heavy copper stator windings and rare-earth rotor magnets that shed thermal build under continuous drilling. Active Feedback-sensing Technology decouples the motor if bit rotation suddenly halts.

AVT Rotary Hammer Hardware Specs

Internal mechanical counterbalances cancel striker vibration before it reaches operator hand grips. Dual 18-volt battery architecture provides 36-volt power without leaving the standard battery platform.

• 1.562-inch solid bit capacity cuts commercial structural anchor holes in reinforced slabs
• 8.4 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
• Active Feedback-sensing Technology shuts down motor power instantly during bit snag events
• SDS-max drive chuck locks large core bits and demolition chisels securely without slip
• Auto-start Wireless System pairs with jobsite dust extractors via Bluetooth for OSHA compliance

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 3.2 amperes, climbing to 34.6 amperes while driving a 1-1/2-inch bit. Battery pack terminal voltage drops from 36.2 volts down to 31.2 volts under peak hammering resistance. Striker cadence hits 2900 BPM under active load. Sound level meters read 94 dBA at the operator position. Gearcase temperatures rise 28 degrees Fahrenheit after fifteen holes.

Field Service Operational Traps

Neglecting bit shank grease causes high-friction galling that seizes expensive SDS-max bits inside the chuck. Finish carpenters hanging drywall trim have no need for this heavy concrete hammer. Never hammer drill into reinforced slabs without checking the electronic clutch status light.

• Grease bit shanks with high-temperature chisel paste before inserting into the chuck.
• Wipe concrete dust off the rubber chuck nose cone after every shift.
• Clean battery terminal contact tracks using dry nylon bristle brushes every week.
