Makita 40V Max XGT Brushless Cordless 4 Speed High Torque 1/2 Inch Square Drive Impact Wrench Kit & 14pc Deep Impact Socket Set Bundle

Description

Fleet mechanics waste productive hours searching for missing impact sockets when stripping heavy machinery undercarriages. The Makita 40V Max XGT Brushless Cordless 4 Speed High Torque 1/2 Inch Square Drive Impact Wrench Kit breaks loose stubborn fasteners with 810 ft-lbs of breakaway torque. Forcing the detent pin anvil against frozen track pins with non-impact sockets shatters the chrome steel, throwing fragments across the maintenance bay.

A 40V max brushless motor couples to an alloy steel twin-hammer impact mechanism enclosed within a reinforced aluminum gear housing. The 1/2-inch square drive anvil features a case-hardened steel detent pin supported by needle roller bearings to resist severe radial shear shock. Makita integrates an electronic four-speed regulator and auto-stop modes, while the companion 14-piece socket pack features heat-treated chrome-molybdenum steel with deep broaching to grip fastener flats secure.

High Torque Fleet Maintenance Hardware

High-voltage battery architecture delivers sustained power under continuous heavy reverse hammering cycles. Deep chrome-molybdenum impact sockets transfer raw torsional energy direct to fastener flats without rounding drive corners.

• 40V max brushless motor produces 560 ft-lbs fastening torque and 810 ft-lbs breakaway torque to strip seized truck lugs.
• 4-speed power selector regulates speeds from 1000 to 2200 RPM to provide precise fastener control on delicate hubs.
• 1/2-inch square drive anvil with pin detent locks sockets positive to eliminate dropped socket hazards inside equipment.
• Twin-hammer impact mechanism strikes at 2700 blows per minute to shatter rust bonds on commercial trailer axles.
• Auto-stop forward and reverse modes shut off rotation after bolt loosening to prevent dropped nuts on shop floors.
• Reinforced aluminum hammer housing sheds clutch heat to prolong bearing grease life under continuous shop use.
• 14-piece deep impact socket set forged from chrome-molybdenum steel resists wall splits under continuous impact shock.

Impact Bench Dynamometer Load Audit

Bench testing demonstrates that the 40V max motor pulls 48 amps peak during continuous reverse hammering on an M24 test bolt. Spindle rotation drops from 2200 RPM free speed down to 1450 RPM under load, striking at 2650 blows per minute. Nose housing temperature rises 38 degrees Fahrenheit after ten continuous 30-second stall tests. Sound levels measure 83 dBA at free spin and hit 98 dBA under full mechanical impact hammering.

Fleet Maintenance Limits Service Directives

High reverse breakaway torque twists tool bodies hard if sockets bind on stripped threads, requiring a braced two-handed grip. Do not use this high-torque wrench with chrome hand sockets, which shatter under impact blows. Dropping the unit onto hard concrete bays cracks composite battery guide rails.

• Blow abrasive brake dust and metal filings from motor intake screens with clean air every shift.
• Coat the detent pin and anvil square with light preservative oil every work week.
• Inspect socket drive walls for hairline cracks before beginning heavy commercial wheel service shifts.
