DEWALT 23-Piece 1/2" Drive Impact Socket Set, Metric/SAE with 72-Tooth Ratchet & Case

DEWALT's 23-piece 1/2" drive impact socket set (DWMT74739) is a compact kit of heat-treated CR-440 impact sockets, a 72-tooth quick-release ratchet, extension and adapter, built for heavy-duty fastening tasks in both metric and SAE sizes.

This impact socket kit combines DirectTorque socket contours, laser-etched size markings and an organized blow-molded case to give mechanics and tradespeople fast access to a wide range of fastener sizes. The set pairs impact-rated construction with a high-tooth-count ratchet to reduce handle swing, while the included accessories extend reach and adapt the drive for different tools. Ideal for garage work, fleet maintenance or professional job sites, the set balances durability and portability.

What sizes and components are included in the set?

The 23 pieces cover a selection of common SAE and metric sockets plus useful accessories so you can tackle both U.S. and international fasteners. The ratchet, extension and adapter expand the set’s versatility for recessed or awkward bolts.

• Mix of metric and SAE impact sockets (various popular sizes for cars and machinery)
• 1/2" drive 72-tooth quick-release ratchet for reduced arc swing
• Extension and drive adapter to reach recessed fasteners or change drive sizes
• Blow-molded carry case for organized storage and transport

How does DirectTorque technology affect fastener grip?

DirectTorque geometry modifies the socket contact areas to better engage fastener corners, helping minimize rounding during high-torque applications. It’s a mechanical design approach to improve grip rather than a chemical treatment.

• Socket contact profile optimized to distribute force across flats
• Reduces slipping on worn or soft fastener heads compared with standard designs
• Works with impact tools—heat-treated CR-440 steel maintains strength under shock loads

Is the ratchet and hardware durable enough for repeated impact use?

The ratchet has a 72-tooth gear count to allow small handle movement between clicks and a quick-release button for secure socket retention. All sockets are heat-treated CR-440 impact-rated steel, designed to withstand repeated use with impact wrenches and drivers.

• 72-tooth ratchet reduces handle swing in tight spaces for faster operation
• Quick-release mechanism secures sockets during use and eases changes
• Heat-treated CR-440 steel sockets rated for impact applications

How does this set fit into a workshop or mobile toolkit?

The compact blow-molded case keeps pieces organized and portable, making it practical for toolboxes, truck storage or a service van. The mixed metric and SAE selection reduces the need to carry multiple socket sets.

• Blow-molded case with labeled recesses for quick inventory
• Compact footprint fits standard tool storage and vehicle compartments
• Mixed sizes cover a broad range of common repair and maintenance tasks

Who is this for: The DEWALT DWMT74739 23-piece impact socket set is aimed at professional mechanics, fleet technicians, contractors and serious DIYers who need a durable, space-efficient kit that works with impact tools and hand ratchets. If you require impact-rated sockets with stamped markings, a high-tooth-count ratchet for tight spaces and a balance of metric and SAE sizes, this set provides a practical, jobsite-ready option without excess bulk.
