Before You Buy

Review package contents carefully before purchasing. Models carrying the “B” suffix, including the DCF845B, DCF860B, DCF870B, and DCF809B, are bare tools; the listings state that batteries and chargers are sold separately. Additionally, while the DCF845 listing highlights TOOL CONNECT readiness, the tracking chip itself is sold separately. If you do not already own compatible 20V MAX batteries and a charger, choosing the DCF787D1 kit provides complete initial equipment.

Verify application requirements against published specifications. Several listings do not specify impact-per-minute (IPM) rates, and exact operating decibel ratings are omitted in favor of percentage comparisons. Furthermore, while all models feature a 1/4-inch quick-change hex chuck, you must ensure your fastening bits and socket adapters use impact-rated 1/4-inch hex shanks to prevent premature bit failure during high-torque driving.

FAQ

How does a hydraulic impact driver differ from a standard mechanical driver?

Standard mechanical impact drivers utilize a spring-driven metal hammer striking an anvil, producing loud acoustic clatter. A hydraulic driver like the DCF870B replaces metal-on-metal impacts with an oil-cushioned hydraulic mechanism. This delivers sustained fastening force with up to 57 percent quieter operation, significantly reducing jobsite noise disturbances in occupied buildings.

What is the benefit of a 3-speed mode selector?

A 3-speed selector allows trades to restrict motor RPM and impact force to suit specific fasteners. Lower speeds prevent head stripping and material blowout when driving small fasteners or sheet metal screws. Higher speeds deliver full power for rapid timber fastening and structural screws.

Can these 1/4-inch impact drivers accept standard round drill bits?

The quick-change chuck on these impact drivers accepts standard 1/4-inch hex-shank bits only. Smooth, round drill bits will not lock into the chuck sleeve. To drill holes in lumber or metal, you must use accessories specifically designed with a 1/4-inch quick-release hex shank.

Are 20V MAX batteries interchangeable across all six impact drivers?

All six models belong to the manufacturer’s 20V MAX system. Any genuine 20V MAX lithium-ion battery, from compact 2.0Ah packs to higher-capacity batteries, will fit and power each driver featured in this guide.

Which impact driver is best suited for tight clearance spaces?

The DEWALT ATOMIC 20V MAX* Impact Driver (DCF809B) is engineered specifically for confined spaces, featuring a head length of just 5.1 inches. This compact profile allows it to fit between narrow wall studs, under cabinetry, and inside equipment bays where standard full-sized drivers cannot reach.
