DEWALT DCD801 & DCD806 Compact Hammer Drill or Driver Manual

Introduction to the DEWALT DCD801 and DCD806

The DEWALT DCD801 and DCD806 are compact 20V MAX XR brushless cordless drills designed for demanding drilling and fastening tasks. Both models use a 1/2-inch keyless chuck, a two-speed transmission, and a variable-speed trigger to provide controlled performance across a wide range of materials. The DCD801 is a drill/driver, while the DCD806 adds a dedicated hammer-drilling mode for masonry applications.

These tools combine professional-level power with a compact form that is useful in confined work areas, on ladders, inside cabinets, and around framing. Their brushless motors help improve runtime, durability, and efficiency compared with traditional brushed designs. The integrated LED work light helps illuminate dark work surfaces, while the belt hook supports convenient tool access during installation work.

The DEWALT DCD801 & DCD806 Compact Hammer Drill or Driver is suitable for electricians, remodelers, carpenters, maintenance technicians, contractors, and capable DIY users. Use the DCD801 for wood, metal, plastic, and general screwdriving. Choose the DCD806 when occasional drilling in brick, block, or other masonry requires an impact-like hammer action. Neither model replaces a rotary hammer for heavy concrete drilling or extended masonry work.

Battery and charger requirements depend on the package purchased. Tool-only versions require a compatible DEWALT 20V MAX battery and charger, while selected kits include batteries, a charger, belt hook, and storage bag.

How to Set Up the DEWALT DCD801 or DCD806

1. Inspect the drill, chuck, battery, and accessory for damage. Do not use cracked, wet, or damaged components.
2. Charge a compatible DEWALT 20V MAX battery using the appropriate DEWALT charger. Allow the battery to cool or warm to room temperature if its temperature is outside normal charging conditions.
3. Slide the charged battery into the tool until it locks securely. Pull gently on the pack to confirm that it is seated.
4. Move the forward/reverse selector to the center position before installing a bit or making adjustments. This locks the trigger.
5. Open the keyless chuck by turning it counterclockwise, insert the bit fully, and tighten the chuck by hand. Remove the chuck key if one is used with an accessory.
6. Select low speed for high-torque screwdriving or large holes. Select high speed for smaller holes and faster drilling. Stop the tool before changing the gear selector.
7. Set the clutch to a low number for small screws and increase it gradually until the fastener seats without stripping. Use the drill setting when full drilling power is required.
8. On the DCD806, select hammer mode only for compatible masonry drilling. Do not use hammer mode on wood, metal, tile, or fasteners.
9. Wear eye protection, secure the workpiece, keep hands away from the rotating chuck, and remove the battery before changing accessories or performing maintenance.

If the tool does not start, check battery seating, charge level, and the position of the forward/reverse selector. If the chuck slips, remove the battery and retighten the accessory securely.

DEWALT DCD801 and DCD806 Troubleshooting Guide

Tool will not start

Check that the battery is charged and fully latched. Move the forward/reverse selector out of the center lock position. Inspect the battery contacts for dirt and allow an overheated tool or battery to cool before retrying.

Bit slips in the chuck

Remove the battery, open the chuck, clean the jaws and bit shank, then reinstall the accessory straight and tighten the chuck firmly by hand. Avoid using worn, bent, or undersized bits.

Fastener strips or overdrives

Reduce the clutch setting, use the correct driver bit, and operate at low speed. Begin with light trigger pressure and increase torque only when necessary.

Drilling feels slow

Confirm the correct speed range and use a sharp bit designed for the material. Apply steady pressure without forcing the tool. For masonry, use the DCD806 hammer mode and a masonry bit. Heavy concrete or deep holes may require a rotary hammer.

Battery runtime is poor

Use a fully charged battery suited to the workload, avoid excessive pressure, and keep ventilation openings clear. Large bits, dense materials, and repeated high-torque operation naturally reduce runtime.

Error codes and support

These drills do not provide a user-facing numeric error-code display. Automatic shutdown or intermittent operation can result from overload, overheating, low battery charge, or excessive rotational movement on versions equipped with protective control systems. Release the trigger, remove the battery, inspect the accessory, and allow the tool to cool.

DEWALT DCD801 & DCD806 Pros and Cons

Advantages

• Compact professional design: The shorter form is easier to control in cabinets, wall cavities, and other restricted spaces than many full-size drills.
• Brushless efficiency: The motor is designed to deliver strong performance while reducing routine brush replacement.
• Flexible control: Two speeds, a variable trigger, and adjustable clutch settings support both delicate fastening and demanding drilling.
• Useful model choice: The DCD801 suits general drilling and driving, while the DCD806 adds hammer drilling without requiring a separate compact tool.
• Common battery platform: Existing DEWALT 20V MAX users can select a tool-only package and use compatible batteries.
• Work-area visibility: The integrated LED helps when drilling under sinks, inside framing, or in poorly lit service areas.

Limitations

• Not a heavy masonry tool: The DCD806 is appropriate for occasional masonry holes, but extended concrete work is better handled by a rotary hammer.
• Battery not always included: Tool-only packages require a separate compatible battery and charger.
• Chuck maintenance matters: Improperly tightened accessories can slip, especially during high-torque drilling.
• Compact size has trade-offs: Users performing continuous heavy drilling may prefer a larger high-torque drill or specialized hammer drill.

The DEWALT DCD801 & DCD806 Compact Hammer Drill or Driver is best for professionals and DIY users who want a versatile, compact cordless drill. Select the DCD801 for general-purpose work; choose the DCD806 if occasional masonry drilling is part of the job.
