Description
Deep-dish aluminum truck wheels trap standard impact anvils, chewing up expensive wheel rims during fast tire changes. The Ingersoll Rand DXS2 1/2 Inch extended anvil wrench reaches deep lug nuts with two inches of extra reach and 1500 ft-lbs of breakaway power. It clears deep rims, but extended anvils flex under high torsional shock loads.
The extended two-inch anvil is hot forged from nickel-chromium-molybdenum alloy steel, induction hardened to resist torsional twist and neck fractures. Inside the front housing, a twin-hammer clutch mechanism delivers balanced rotational blows to reduce side-loading on the anvil shank. The air motor incorporates phenolic composite rotor vanes sweeping a micro-honed ductile iron motor cylinder, supported by double needle roller bearings that hold tight end-plate tolerances under severe radial runout forces.
Hardware Performance Matrix
Commercial tire maintenance and fleet service demand deep wheel clearance and maximum rotational breaking force. This extended-anvil impact wrench removes recessed fasteners without requiring torque-robbing socket extension bars.
- 2-inch extended square drive anvil accesses recessed lug nuts inside deep-dish commercial wheels
- 1500 ft-lbs nut-busting torque shatters frozen wheel studs and seized fleet chassis hardware
- Hot-forged alloy steel anvil metallurgy resists torsional fracturing under heavy repetitive impact cycles
- Twin-hammer impact mechanism balances rotational impacts to reduce stress on internal hammer pins
- Titanium hammer case front housing defends internal clutch parts against heavy shop floor drops
- 1/4-inch NPT air inlet port interfaces with high-flow fittings to ensure maximum pneumatic volume
- Multi-stage quiet exhaust deflector routes vented air away from the operator while cutting noise
Dyno Realities Air Telemetry
Torque dyno testing shows air consumption of 31 CFM at 90 PSI dynamic under full stall load, dropping to 4.7 CFM at free-run. Free speed measures 8300 RPM, delivering 1300 blows per minute. Dynamic line pressure drop across 50 feet of 1/2-inch hose measures 5 PSI during full breakaway stall. Adiabatic air expansion plunges exhaust temperatures down to 26 degrees Fahrenheit, demanding moisture separator traps upstream. Acoustic noise output meters at 89 dBA under load.
Field Trade-Offs Application Filter
The two-inch anvil extension improves wheel clearance, yet added length shifts the center of gravity forward, increasing wrist strain. Machine shop operators doing delicate bench teardown should not purchase this unit; extended anvil mass combined with 1500 ft-lbs torque will snap small fasteners without warning.
- Inject five drops of ISO VG 32 pneumatic oil into the air inlet before starting operations.
- Lube the front hammer mechanism with synthetic impact grease every fifty operating hours.
- Inspect the anvil friction ring groove for metal burrs that prevent positive socket retention.
Commercial Warranty Package Inventory
Ingersoll Rand protects this extended anvil tool with a 2-Year limited commercial warranty covering drive motor and hammer clutch failure. The retail carton contains the pneumatic impact wrench, an extended anvil friction ring replacement, an air inlet connector, a protective rubber boot, and a manufacturer safety booklet.
