Ingersoll Rand 1/2 Inch Square Impactool Air Pistol, 450 Ft-Lbs Max Torque

Description

Mechanics battle frozen lug nuts with the Ingersoll Rand 1/2-Inch Impactool Wrench to break stubborn automotive suspension bolts and rusty wheel hardware without tool stalls. The classic twin-hammer impact mechanism generates up to 450 ft-lbs of maximum breakaway torque at 8000 RPM free speed on 90 PSI shop air. Automotive technicians spin heavy fasteners rapidly. The high-torque pneumatic impact draws 4.2 CFM average and 22 CFM under full hammer stall.

Precision-cast aluminum forms the front hammer case, protecting the dual forged steel impact hammers from severe shop floor drops. A high-density composite rear housing surrounds the 6-vane air motor, balancing tool weight to reduce wrist fatigue during all-day tire rotations. The pressure-feed lubrication system distributes grease evenly across hammer pins. Sized for service bays, the bare impact wrench weighs 5.8 lbs, measuring 7.3 inches long with a 1/2-inch square drive hog-ring anvil.

Twin-Hammer Torque Dynamic Bench Limits

Dynamometer bench testing confirms the twin-hammer clutch produces 450 ft-lbs of ultimate breakaway torque in reverse, with forward working torque calibrated from 25 to 350 ft-lbs across five power regulator settings. Testing on Grade-8 3/4-inch frozen suspension bolts demonstrates break-loose times under 1.8 seconds at 90 PSI dynamic inlet pressure. The twin-hammer mechanism delivers 1200 impacts per minute, while the contoured rear exhaust deflector keeps exhaust air directed away from the operator.

Key Features of Ingersoll Rand 231C

Automotive service mechanics and tire shop technicians buy Ingersoll Rand 1/2-Inch Impactool Wrenches to spin vehicle lug nuts and break stubborn chassis hardware. Compare professional 1/2-inch pneumatic impact wrench pricing to upgrade your automotive service bay tooling.

• Twin-hammer impact mechanism delivers 450 ft-lbs of maximum reverse torque with balanced, smooth impact blows cleanly.
• Adjustable multi-position power regulator controls forward torque output across five settings to prevent overtightening cleanly.
• Pressure-feed lubrication system forces grease into hammer pins and clutch faces, extending internal tool life cleanly.
• Standard 1/2-inch square drive anvil with friction ring socket retainer allows rapid impact socket changes cleanly.
• Contoured ergonomic grip handle balances tool center of gravity comfortably, minimizing operator hand fatigue cleanly.
• Two-piece construction allows easy shop teardown, cleaning, and replacement of motor vanes after years of service.

Automotive Bay Negative Selection Filter

The variable-speed trigger permits feathering motor throttle, starting nuts onto threads smoothly without cross-threading. Do not purchase this 1/2-inch impact wrench for heavy commercial semi-truck 1-inch axle nuts requiring over 1000 ft-lbs, delicate micro-fastener assembly under 20 ft-lbs, or operating on small 2-gallon compressors lacking 5 CFM delivery. Routine care requires adding six drops of air tool oil into the air fitting daily before connection, and greasing the hammer case monthly.

Factory Warranty Delivery Manifest
