DEWALT DCD740 Right-Angle Drill & Driver Manual

Introduction

The DEWALT DCD740 Right-Angle Drill & Driver is a cordless tool designed for drilling and fastening where a conventional drill cannot fit. Its compact right-angle configuration helps users work between studs, inside cabinets, beneath flooring, and in other confined spaces. The tool is available in regional versions using DEWALT 20V MAX or 18V XR battery systems, so users should match the drill, battery, charger, and manual to the model designation supplied in their market.

A two-speed transmission provides a low range from 0 to 650 rpm for controlled drilling and screwdriving and a high range from 0 to 2,000 rpm for faster drilling in suitable materials. The compact 3/8-inch or 10 mm keyless chuck accepts common drill and driver accessories, while the automatic spindle lock helps simplify bit changes. A multi-position trigger, LED work light, and balanced handle design improve control when access and visibility are limited.

This right-angle drill is intended for tradespeople, electricians, plumbers, carpenters, installers, maintenance technicians, and capable DIY users. Typical applications include drilling through wood framing, installing hardware, fastening screws, and completing light- to medium-duty work in restricted areas. It is especially useful when the length of a standard drill prevents a straight approach.

Read the complete manufacturer’s instructions before operation. Use the correct battery platform, accessory, speed setting, and personal protective equipment for every task.

How to Set Up the DEWALT DCD740 Right-Angle Drill & Driver

Inspect the drill, chuck, battery, and accessory for damage. Do not operate a tool with cracked housing, damaged controls, or a defective battery.
Charge a compatible DEWALT lithium-ion battery with the correct charger. Insert the battery into the tool until it locks securely.
Move the forward/reverse selector to the center position before installing an accessory or making adjustments.
Open the keyless chuck by hand, insert the drill bit or driver bit fully and straight, and tighten the chuck firmly. Remove the chuck key if one is used with an accessory.
Select first gear for higher control and torque or second gear for faster drilling. Never change gears while the trigger is pulled.
Choose forward rotation for drilling and normal fastening. Use reverse only to remove screws or back a bit out of a hole.
Press the trigger gradually and allow the bit to reach the appropriate speed before applying steady pressure.

There is no Bluetooth pairing or wireless connectivity procedure for this drill. If the tool does not run, remove and reinstall the battery, confirm that the selector is not in its center lock position, and test the battery on an approved compatible tool.

Safety warning: Wear eye protection, secure the workpiece, keep hands away from rotating parts, and disconnect the battery before changing accessories or servicing the tool. Do not force a bit, exceed accessory limits, or use the drill in wet conditions unless the manufacturer specifically permits it.

Troubleshooting the DEWALT DCD740

Drill does not start

Check that the battery is charged and fully seated. Move the forward/reverse selector completely to the forward or reverse position. If the battery or tool is unusually hot, allow it to cool before trying again. Clean dust from the battery contacts with a dry cloth.

Chuck will not hold the bit

Remove the battery, open the chuck, and reinstall the bit so it is centered and inserted deeply enough for secure clamping. Tighten the chuck by hand using firm pressure. Replace worn or damaged bits and inspect the chuck for contamination or mechanical damage.

Drilling is slow or the motor stalls

Use the correct gear, reduce feed pressure, and select a bit designed for the material. Large bits generally require the lower speed range. Withdraw the bit periodically to clear chips, particularly when drilling metal. A depleted battery can also reduce performance.

LED does not illuminate

Confirm that the battery is installed and lightly press the trigger. If the drill operates but the LED remains off, discontinue use if visibility is inadequate and arrange professional service.

Error codes and support

The DCD740 is not generally documented with a user-facing numeric error-code display. Flashing battery indicators or unusual shutdown behavior should be handled according to the battery and charger instructions rather than interpreted as a drill error code.

For warranty evaluation, manuals, replacement parts, repair locations, and model-specific assistance, use DEWALT’s official support center or ServiceNet portal. In the United States, DEWALT lists customer-care assistance at 1-800-433-9258. Have the model number, type number, purchase information, and a description of the problem available.

Pros and Cons

Advantages

Excellent access: The right-angle body reaches between framing members and inside cabinets more easily than a standard drill.
Flexible speed control: Two mechanical speed ranges cover controlled fastening and faster drilling tasks.
Convenient bit changes: The compact keyless chuck avoids the separate chuck key typical of older drills.
Improved visibility: The integrated LED helps illuminate the work area in dark cavities.
Multiple hand positions: The multi-grip trigger is useful when the tool must be held at an unusual angle.
Cordless operation: Battery power eliminates extension cords and supports work on unfinished sites.

Limitations

Restricted chuck size: A 3/8-inch or 10 mm chuck is less suitable for very large accessories than many full-size drills.
Battery and charger may be separate: Bare-tool kits do not necessarily include a battery, charger, belt hook, or case.
Brushed motor design: Users seeking maximum efficiency, reduced maintenance, and longer runtime may prefer a newer brushless model.
Not a hammer drill: It is not the appropriate choice for masonry impact drilling unless a specific approved accessory and application permit it.
Best for confined-space work: Users mainly drilling large holes or performing heavy-duty continuous work may need a higher-capacity drill.

The DEWALT DCD740 Right-Angle Drill & Driver suits professionals and DIY users who prioritize compact access, two-speed control, and compatibility with an existing DEWALT battery platform.

Faqs

How do I set up the DEWALT DCD740 Right-Angle Drill & Driver for the first time?

Charge a compatible DEWALT 18V XR or 20V MAX slide battery using the correct charger, then remove the battery before installing a bit. Open the 3/8-inch ratcheting chuck, insert the bit fully, and tighten the chuck by hand until secure. Slide the battery into place, select forward or reverse, and choose the lower or higher speed range. Test the trigger briefly before starting work, keeping the bit clear of nearby surfaces.

Why is my DEWALT DCD740 Right-Angle Drill & Driver not starting?

First remove and reinstall the battery firmly, checking that it is charged and its terminals are clean. Confirm the forward/reverse selector is centered correctly or moved fully to the desired direction; a partially engaged selector can prevent operation. Inspect the trigger and battery for visible damage. If the tool still does not run, allow an overheated battery or motor to cool. Do not bypass safety features or disassemble the drill; arrange qualified service if the problem remains.

Which battery and charger work with the DEWALT DCD740 Right-Angle Drill & Driver?

The DEWALT DCD740 is designed for DEWALT 18V XR or 20V MAX slide-style lithium-ion batteries, depending on the regional version and labeling. Use a DEWALT charger approved for that battery platform rather than mixing incompatible battery systems. Check the battery and charger labels before use, especially when switching between North American 20V MAX and international 18V XR products. The tool-only model does not automatically include a battery or charger.

When should I use the low or high speed on the DEWALT DCD740 Right-Angle Drill & Driver?

Use the low-speed range, up to approximately 650 RPM, when drilling larger holes, driving screws, or working with materials that require greater control. Select the high-speed range, up to approximately 2,000 RPM, for smaller drill bits and faster drilling in suitable materials. Start slowly with the variable-speed trigger, keep the bit aligned, and avoid changing the gear selector while the chuck is rotating. Let the motor stop completely before switching ranges.

How can I stop bits from slipping in the DEWALT DCD740 Right-Angle Drill & Driver chuck?

Open the 3/8-inch ratcheting chuck fully, clean dust from the jaws and bit shank, and insert the bit straight and deeply enough for secure contact. Tighten the chuck firmly by hand around the bit; do not hold the chuck while operating the trigger. Avoid using damaged, undersized, or excessively worn bits. For short hex-shank driver bits, use the chuck’s deep hex pocket when appropriate, then test the bit at low speed before applying load.

Can the DEWALT DCD740 Right-Angle Drill & Driver drill through wood and metal?

Yes, the DEWALT DCD740 is intended for drilling and fastening applications in materials such as wood and metal when the correct bit is used. Select a sharp wood bit for timber and a suitable metal bit with appropriate cutting lubricant when required. Use the low-speed range for larger holes and maintain steady pressure without forcing the motor. Confirm the bit size and material thickness are within the tool and accessory limits before drilling.

How do I improve runtime and performance with the DEWALT DCD740 Right-Angle Drill & Driver?

Use a fully charged battery suited to the task, select the lowest effective speed, and keep drill bits sharp. Excessive pressure, binding, and repeated operation at maximum speed increase battery drain and heat. Clear chips from the hole periodically, especially when drilling metal, and avoid using a bit that is too large for the material. Allow the tool and battery to cool between demanding operations, and store spare batteries at moderate temperature.

How should I clean and maintain the DEWALT DCD740 Right-Angle Drill & Driver?

Remove the battery before cleaning or inspecting the DEWALT DCD740. Wipe the housing with a dry or slightly damp cloth and use gentle compressed air to clear dust from the chuck, vents, and trigger area. Do not immerse the drill or use solvents that can damage plastic components. Check the chuck, selector, battery contacts, and housing for wear or cracks. Store the tool without a bit installed, away from moisture, and replace damaged parts through an authorized service provider.
