Milwaukee 2466-20 Digital Torque Wrench with Battery

The Milwaukee 9993263 kit delivers the M12 FUEL 2466-20 1/2" Digital Torque Wrench and the M12 REDLITHIUM HIGH OUTPUT XC5.0 Battery Pack (48-11-2450) together — purpose-matched for aviation maintenance operations where wheel assemblies, propeller hardware, landing gear fasteners, and heavy structural bolts require documented, high-accuracy torque and a tool that is ready to run the moment it's needed. For A&P mechanics and MRO technicians who cannot afford a battery delay on the most safety-critical fastener applications in aircraft maintenance, this kit eliminates that failure mode from day one.

The Right Battery for the Heaviest Aviation Torque Applications

The 2466-20's POWERSTATE brushless motor drives 1/2" drive fasteners to within torque range at up to 100 RPM — and at the sustained output required for wheel change rotations, propeller reinstallations, and landing gear hardware, the battery pairing is not incidental to performance. The 48-11-2450 M12 REDLITHIUM HIGH OUTPUT XC5.0 delivers 25% more power and runs 25% cooler than Milwaukee's standard REDLITHIUM XC pack. On a 1/2" digital torque wrench running high-torque cycles continuously through heavy maintenance work, that thermal advantage translates directly to sustained peak motor output, more consistent torque delivery across a full job, and longer battery service life under demanding conditions. The resistant housing is rated for brake fluid, hydraulic fluid, and cleaning solvent exposure — the ambient chemistry of wheel and landing gear maintenance environments — making it the correct battery for this application, not just a convenient one.

• 25% more power and 25% cooler operation vs. standard M12 REDLITHIUM XC — sustains peak motor output through wheel changes, propeller work, and heavy structural fastening cycles
• 5.0 Ah capacity with fade-free power delivery — maximum fastening cycles per charge on extended MRO shifts
• Brake fluid, hydraulic fluid, and solvent-resistant housing — rated for wheel well and landing gear maintenance environments
• Below 0°F / -18°C rated — delivers full performance in cold ramp and hangar conditions
• REDLINK intelligence — real-time battery, tool, and charger communication for overload and over-discharge protection under heavy structural fastener loads
• Compatible with 125+ M12 tools — extends battery value across the technician's full M12 toolset

2466-20: Documented ONE-KEY Torque at the Highest-Consequence Fastener Range

The 2466-20 covers the 12.5–150 ft-lb range on a 1/2" drive — the band that governs wheel and brake assembly hardware, propeller flange bolts, landing gear strut attachment points, engine mount fasteners, and heavy structural airframe bolts. These are the fasteners where under-torque risks in-service failure and over-torque risks component damage, and where having a documented record of every torque value applied is both an airworthiness best practice and an increasingly expected quality management deliverable. ONE-KEY Bluetooth logs every torque event and generates downloadable reports that support FAA AC 43.13 documentation, Part 145 quality sign-off, and AS9100-aligned torque record keeping — replacing handwritten logs with verified, time-stamped digital records that inspectors and QA managers can pull before release to service. Adjustable run-down torque prevents the POWERSTATE motor from over-driving on composite panels, aluminum castings, and titanium hardware. Four simultaneous notification modes — audible, LED, LCD, vibratory — confirm torque achievement when the technician is inside a wheel well or working without a clear sightline to the display.

• 1/2" drive, 12.5–150 ft-lb, ±2% CW / ±3% CCW accuracy — covers wheel assemblies, propeller hardware, landing gear, engine mounts, and heavy structural fasteners
• ONE-KEY torque logging — downloadable reports for FAA AC 43.13, Part 145, and AS9100 documentation and quality sign-off
• ONE-KEY tool tracking, remote lockout, and inventory management — FOD risk reduction for controlled tool environments and Part 145 tool control programs
• Adjustable run-down torque — protects aluminum castings, composite panels, and titanium hardware from over-torque damage
• 5,000-cycle recalibration interval — aligns with standard MRO toolroom maintenance schedules
• Calibration certificate included — supports formal Part 145 and ISO 9001 tool introduction documentation
• 5-year wrench warranty | 3-year battery warranty
