Real Tool Reviews tests the EarthQuake XT 1/2 in. Composite Xtreme Torque Air Impact Wrench side-by-side against the Snap-On MG725

The professional-grade EarthQuake XT Impact Wrench is a big hit with customers. Features range from the lightweight design for reduced fatigue to its through-the-handle exhaust that keeps debris away from the operator. However, when it really comes down to the nuts and bolts of EarthQuake XT’s performance, some question whether this tool performs as well as it claims, especially compared to its Snap-On counterpart priced significantly higher.

In a recent product comparison video produced by Real Tools Review, the EarthQuake 1/2 in. Composite Xtreme Torque Air Impact Wrench goes head to head (or this case—anvil to anvil) with the ½ in. Snap-On MG725. Brace for impact because the results may surprise you…

The review starts off with basic feature comparisons.


Weight with a fitting installed
XT: 4 lbs, 7 oz.
MG725: 5 lbs., 1 oz.

Height (top of impact to bottom of fitting)
XT: 9-1/2 in.
MG725:  9-1/2 in.

XT:  2-3/4 in.
MG725: 2-3/4 in.

XT: 7-1/4 in.
MG725: 7-3/4 in.

Speed/Power Modes
XT: 3 speed/power modes that work in forward and reverse; large dial for easy switching between modes
MG725: 3 speed/power modes that work in forward, reverse operates in max torque mode only; small dial knob for switching between modes

XT and MG725 both have variable speed triggers

XT: Metal and composite housing
MG725: all metal housing but with rubber overmold grip and top pad

XT and MG725 both have 3/8 in. air fittings with ¼ in. NPT threads
(Can turn line pressure down lower compared to ¼ in. air fitting)

Both XT and MG725 have friction ring anvils
(Enables attachment of standard sockets without falling off during use or depressing a pin to detach – ideal for automotive use)

The basic shape and dimensions of both impact wrenches are relatively similar but the EarthQuake XT is a bit more compact. Additionally, the EarthQuake impact wrench weighs in a half-pound lighter, which can make a huge difference in terms of reduced fatigue when using an impact wrench for an extended period of time.

EarthQuake XT has the advantage with three speed/power modes in reverse compared to Snap-On’s single max torque only reverse mode. EarthQuake XT’s speed/power mode dial is also larger and easier to operate compared to the small knob on the Snap-On model, especially with gloved or greasy hands.

EarthQuake XT’s metal and composite design has an advantage over brands with rubber on the housing because certain chemicals (e.g. brake cleaner) can swell rubber. Snap-On does offer a protective boot at an additional cost which can help prevent scratches and other potential surface damage. It also has a flat rubber top to prevent the impact wrench from falling over when set down as well as a rubber sleeve on the handle to protect the hand from freezing when compressed air flows through the tool.

After the features, the review moves on to the much-anticipated torque testing, running three separate scenarios: maximum reverse torque, forward working torque and dynamic torque (forward and reverse).

Torque Tests

Maximum reverse working torque
XT: 1,000 ft. lbs.
MG725: 1,002 ft. lbs.

Forward working torque
XT: 869 ft. lbs.
MG725: 860 ft. lbs.

Impact Wrench Dynamic Torque Testing

Dynamic torque forward, lowest power
XT: 275 ft. lbs.
MG725: 332 ft. lbs.

Dynamic torque forward, medium power
XT: 325 ft. lbs.
MG725: 399 ft. lbs.

Dynamic torque forward, maximum power
XT: 450 ft. lbs.
MG725: 421 ft. lbs.

Dynamic torque reverse, lowest power
XT: 301 ft. lbs.
MG725: 465 ft. lbs. (max setting only)

Dynamic torque reverse, medium power
XT: 346 ft. lbs.
MG725: 465 ft. lbs.  (max setting only)

Dynamic torque reverse, maximum power
XT: 465 ft. lbs.
MG725: 465 ft. lbs. (max setting only)

Performance Results

Comparison 2

Overall, the three tests reveal both impact wrenches perform within very close torque ranges of each other with the EarthQuake having a higher dynamic forward torque of 450 ft. lbs., almost 30 ft. lbs. more than the Snap-On MG725.

While both impact wrenches generate identical maximum dynamic torque in reverse (465 ft. lbs.), EarthQuake XT offers more control with three settings—using the maximum setting only (as with the Snap-On impact wrench) could potentially snap the head off a bolt.

Snap-On does offer a two-year warranty on their impact wrench straight out of the box. EarthQuake XT comes with an initial 90-day warranty and the option of adding a one or two-year extended warranty for a nominal additional cost.

Where the EarthQuake XT really outperforms its Snap-On counterpart is on price—the Snap-On MG 725 sells for nearly 3-1/2 times higher than the 1/2 in. Composite Xtreme Torque Air Impact Wrench.
