How to Set Up the Craftsman CMCD732 Cordless Hammer Drill

Inspect the drill, chuck, battery, charger, and bit for visible damage. Do not use damaged components.
Charge a compatible V20 battery using the appropriate Craftsman charger. Allow the battery to cool if it is hot after use.
Insert the battery into the drill until it locks securely. Pull gently on the pack to confirm that it is seated.
Open the 1/2-inch ratcheting chuck by rotating it counterclockwise. Insert the bit straight into the chuck, then tighten the chuck firmly by hand.
Select first gear for slower, higher-torque work such as driving large fasteners. Select second gear for faster drilling in suitable materials.
Rotate the mode collar to drilling, screwdriving, or hammer-drilling mode. Use the clutch for screws and the drill setting for unrestricted drilling.
Check the forward/reverse selector before pulling the trigger. Keep the selector centered when carrying or storing the tool.
Test the tool at low speed before beginning the workpiece.

Wear eye protection, keep hands away from the rotating bit, and secure the workpiece. Disconnect the battery before changing bits or accessories. If the drill does not run, remove and reinstall the battery, verify the selector is fully in forward or reverse, and check the battery charge.

Craftsman CMCD732 Troubleshooting Guide

Drill does not start

Check that a charged V20 battery is installed correctly and that the forward/reverse selector is not in the center lock position. Allow an overheated battery or motor to cool before trying again.

Chuck does not hold the bit

Remove the battery, clean debris from the chuck jaws, insert the bit straight, and tighten the ratcheting chuck securely. Replace worn or damaged bits and avoid using accessories that do not fit the chuck properly.

Drilling speed is too low

Confirm that second gear is selected when appropriate, press the variable-speed trigger smoothly, and use a sharp bit designed for the material. Excessive pressure can reduce performance and increase heat.

Battery drains quickly

Use a fully charged battery, reduce unnecessary trigger operation, and select the correct gear and bit. Large masonry holes, heavy drilling, and repeated high-load work naturally consume more energy.

Bit overheats or stalls

Reduce pressure, withdraw the bit periodically to clear debris, and allow the bit to cool. Do not continue using a dull bit or force the drill through a bind.

Error codes and support

The CMCD732 does not rely on a user-facing numeric error-code display. Battery or thermal protection may interrupt operation without showing a code. Stop work, remove the battery, inspect the tool, and allow it to cool. For product support, manuals, warranty service, and repair information, contact Craftsman customer service at 1-888-331-4569 or use the customer-support section of the Craftsman website. The tool carries a three-year limited warranty, subject to exclusions for normal wear, misuse, and abuse.

Craftsman CMCD732 Pros and Cons

Advantages

Brushless efficiency: The motor is designed to provide strong cordless performance with less routine maintenance than a brushed motor.
Versatile operation: Drilling, screwdriving, and hammer drilling support a wide range of home improvement and trade applications.
Two-speed control: The 0–600 RPM range favors torque and control, while the 0–1,900 RPM range supports faster drilling.
Secure chuck: The 1/2-inch ratcheting chuck is suitable for many common drill bits and accessories.
Shared battery platform: Existing Craftsman V20 users can use compatible battery packs across supported tools.

Limitations

Not a rotary hammer: Hammer-drill action is appropriate for occasional masonry holes, but frequent heavy concrete drilling may require a dedicated SDS rotary hammer.
Battery-dependent: Performance and runtime vary with battery capacity, material, bit size, and workload.
Manual chuck operation: The keyless ratcheting chuck is convenient, but it requires firm hand tightening for reliable bit retention.
Potentially more tool than needed: Users who only drive small screws may prefer a lighter drill/driver.

The craftsman CMCD732 Brushless RP Cordless Hammer Drill is best suited to users who want one capable V20 tool for general drilling, fastening, and occasional masonry work. Choose a heavier-duty rotary hammer or specialized drill when continuous concrete drilling is the primary requirement.

Faqs

How do I set up the craftsman CMCD732 Brushless RP Cordless Hammer Drill for the first time?

Charge a compatible CRAFTSMAN V20 MAX lithium-ion battery, then slide it into the drill handle until it locks. Insert the appropriate bit into the 1/2-inch keyless chuck and tighten it by hand. Select the desired speed range, drilling mode, and clutch setting before pulling the variable-speed trigger. For masonry, choose hammer-drill mode; for wood or metal, use standard drilling mode. Remove the battery before changing accessories or performing adjustments.

Which battery and charger work with the craftsman CMCD732 Brushless RP Cordless Hammer Drill?

The craftsman CMCD732 Brushless RP Cordless Hammer Drill uses CRAFTSMAN V20 MAX lithium-ion battery packs. Compatible packs include models such as CMCB201, CMCB202, CMCB204, CMCB205, CMCB206, CMCB209, CMCB2011, and CMCB2015. Compatible chargers include CMCB100, CMCB101, CMCB102, CMCB104, CMCB1104, and CMCB124. Confirm the exact battery and charger model against the tool manual before use, and never force an incompatible pack into the tool.

Why is the craftsman CMCD732 Brushless RP Cordless Hammer Drill not turning on?

First, remove and reinstall the battery to ensure it is fully seated. Check the battery charge indicator and try a known-good compatible V20 MAX battery if available. Inspect the trigger area for debris and make sure the forward/reverse selector is centered correctly; the center position can lock the trigger. If the drill still does not run, allow an overheated tool or battery to cool. Persistent failure may require authorized service rather than disassembly.

How do I prevent the craftsman CMCD732 Brushless RP Cordless Hammer Drill from overheating?

Use the correct bit for the material and avoid forcing the tool through the workpiece. Let the motor maintain speed instead of applying excessive pressure, and use the lower speed range for demanding drilling or larger bits. Clear chips regularly when drilling metal or wood. During masonry work, periodically release the trigger and allow the drill to cool. If the tool becomes unusually hot, stops under load, or smells burnt, remove the battery and discontinue use until it has been inspected.

When should I use hammer-drill mode on the craftsman CMCD732 Brushless RP Cordless Hammer Drill?

Use hammer-drill mode for drilling small holes in masonry materials such as brick, block, or concrete with a suitable masonry bit. The impact action helps the bit break through mineral-based surfaces. Do not use hammer mode for wood, plastic, or ordinary metal drilling because it can damage the workpiece or bit. Hold the drill firmly with both hands when appropriate, keep the bit aligned, and apply steady pressure without forcing it.

How can I get better drilling performance from the craftsman CMCD732 Brushless RP Cordless Hammer Drill?

Choose the correct speed range before drilling: the lower range provides better control and is useful for larger bits or heavy work, while the higher range suits smaller bits and faster drilling. Match the clutch setting to the task when driving screws, but use the drill setting for drilling holes. Keep bits sharp, mark the drilling point, and clamp loose material securely. A fully charged V20 MAX battery and moderate trigger pressure also improve control and runtime.

What should I do if the chuck on the craftsman CMCD732 Brushless RP Cordless Hammer Drill slips?

Remove the battery before inspecting the chuck. Open the keyless chuck, clean dust or debris from the jaws and bit shank, then insert the bit straight and tighten the chuck firmly by hand. Avoid gripping the chuck with pliers, which can damage its surface. Use a bit with a clean, undamaged shank and avoid excessive side pressure during drilling. If the chuck continues loosening or the jaws do not close evenly, arrange professional service.

How should I clean and store the craftsman CMCD732 Brushless RP Cordless Hammer Drill?

Remove the battery before cleaning or storing the drill. Wipe the housing with a dry or slightly damp cloth, and use a soft brush or gentle air stream to clear ventilation openings and the chuck. Do not use solvents, immerse the tool, or block the motor vents. Store the drill and battery in a dry, protected location away from extreme heat and moisture. Remove the bit after use and keep the battery separate when the tool will not be used for an extended period.
