DEWALT 20V 1/2 High Torque Impact Wrench Kit

Description

Low-torque impact wrenches fail to dislodge seized, rusted suspension pivot bolts on heavy commercial fleet chassis. The DEWALT 20V 1/2 High Torque Impact Wrench Kit breaks stubborn fasteners loose with 1200 foot-pounds of fastening torque. An 18-volt brushless motor drives a heavy twin-hammer mechanism producing 1890 blows per minute. Attempting to use thin chrome hand sockets will shatter socket walls.

Die-cast aluminum front housings protect a massive twin-hammer impact clutch forged from vacuum-degassed AISI 4140 chrome-molybdenum steel. The half-inch square drive anvil uses an induction-hardened friction ring socket retainer that grips impact sockets firmly under violent directional changes. The brushless motor wet-end incorporates neodymium rotor magnets and heavy-gauge copper stator coils that withstand sustained high-amperage draws. Glass-filled nylon body housings resist fleet garage chemical washdowns, engine oils, and brake fluids.

High Torque Impact Hardware Specs

Twin-hammer clutches produce 1750 foot-pounds of breakaway torque to shatter seized suspension hardware. Precision four-mode speed selectors tailor forward fastening speeds to prevent thread stripping.

• 1200 foot-pounds of maximum fastening torque secures heavy structural equipment fasteners
• 1750 foot-pounds of breakaway torque dislodges rusted commercial truck lug nuts in seconds
• Four-mode drive control selects three RPM speeds plus precision wrench mode for fastener control
• Half-inch square drive anvil with friction ring enables rapid impact socket changes
• Brushless 20-volt motor platform provides high rotational torque with low battery power drain
• Glass-filled nylon housing resists motor oil, hydraulic fluid, and shop chemical exposure
• Integrated LED work light illuminates dark vehicle undercarriages and suspension bays

Impact Dyno Bench Telemetry

Dynamometer bench testing tracks electric current and peak impact torque on calibrated grade eight fasteners. Unloaded motor rotation draws 2.8 amperes from the 20-volt battery, surging to 36.4 amperes during heavy anvil stall resistance. Pack terminal voltage drops to 16.2 volts during maximum breakaway impact cycles. Anvil impacts hit 1890 BPM with peak breakaway torque reaching 1750 foot-pounds. Acoustic sound meters register 102 dBA during active socket hammering. Front housing temperatures rise 28 degrees Fahrenheit after ten lug nut cycles.

Fleet Service Operational Traps

Using thin chrome hand sockets on this high-torque anvil shatters sockets and ruins anvil retainers. Technicians assembling light automotive dashboard trim have no need for this heavy impact gun. Never run this impact wrench without fully seating impact-rated sockets onto the friction ring.

• Inspect the friction ring anvil nose for metal wear or missing retaining O-rings weekly.
• Wipe corrosive road salt and engine grime off battery contacts with dry nylon brushes.
• Blow metal grit out of motor cooling vents using clean dry compressed air.

Commercial Warranty Package Inventory

DEWALT provides a 3-Year limited commercial warranty covering drive mechanisms and motor electronics. The kit carton includes the half-inch high torque impact wrench, one 20-volt 5.0Ah oil-resistant battery, fast charger, and heavy contractor bag.
