Introduction

This CRAFTSMAN CMCF800C1 review covers the V20 20V MAX 1/4-inch impact driver kit sold with one battery and a charger. It is aimed at homeowners, DIY users, and maintenance technicians who want a cordless fastening tool without buying a battery and charger separately. CRAFTSMAN lists it as a kit, not a bare tool.

Figures below come from the CRAFTSMAN product page for CMCF800C1. This is not a hands-on test, and it does not include prices, star ratings, or customer stories. Do not confuse this brushed kit with later brushless CRAFTSMAN impacts such as the CMCF813 or CMCF830.

Product overview

An impact driver is a fastening tool, not a drill. A 1/4-inch hex collet holds driver bits. Inside, a hammer-and-anvil mechanism delivers rotational impacts so screws and bolts turn with less twisting force at the wrist than a drill/driver alone. That makes it useful for deck screws, cabinet hardware, furniture assembly, bracket installs, and other repetitive fastening once the correct bit and fastener are chosen.

The CMCF800C1 runs on CRAFTSMAN V20 batteries. CRAFTSMAN notes that 20V MAX is the maximum initial voltage measured without a workload, and that nominal voltage is 18. The kit includes one 1.5Ah pack, so runtime is suited to shorter home and maintenance sessions rather than all-day production fastening.

Key features

• 1/4-inch hex quick-release chuck
• LED work light
• Cordless V20 / 20V MAX operation
• Manufacturer-listed 1,460 in-lbs, max 2,800 RPM, and 3,100 IPM
• One 1.5Ah battery and charger in the kit
• Brushed motor, per the CRAFTSMAN specification table

Performance and practical uses

Based on the published specification, not on a personal test, the CMCF800C1 is positioned for fastening rather than boring large holes. Typical jobs include driving screws during furniture assembly, hanging hardware, light carpentry repairs, and maintenance fastening where an impact-rated 1/4-inch bit fits the fastener.

A single 1.5Ah pack is a real limit. Plan to charge between longer projects, or add another V20 pack if you already know the work will run past one battery. For seized automotive fasteners, a dedicated impact wrench is the better tool class. For drilling holes, use a drill/driver and the correct bit.

Pros and cons

Pros

• Battery and charger are included, so a first-time buyer can start without a second purchase
• 1/4-inch quick-release chuck and LED are listed by the manufacturer
• Published torque and speed figures are specific enough to compare with other impacts
• V20 batteries can be shared with other CRAFTSMAN V20 tools
• Useful size class for furniture, fixtures, and home repairs

Cons

• The motor is brushed, not brushless
• Only one 1.5Ah battery is included
• Not a substitute for a drill when you need to bore holes, or for an impact wrench on rusted hardware
• Bits are not listed as included
• Users already invested in DEWALT 20V MAX, Milwaukee M18, or RYOBI ONE+ may prefer to stay on that charger

CRAFTSMAN impact driver maintenance

Follow the official CMCF800 manual for cleaning, charging, and service. The notes below are general care, not a substitute for that manual.

• Clean dust and debris from the housing and ventilation openings. Do not spray liquid into the tool.
• Inspect the chuck, bits, battery, and charger for cracks, bent contacts, or a collet that no longer holds a bit.
• Use compatible V20 batteries and the correct CRAFTSMAN charger. Do not force another brand’s pack into the foot.
• Store the tool and battery according to the manufacturer’s instructions, away from extreme heat, moisture, and a full discharge for long periods.
• Stop using the tool if it smokes, sparks unexpectedly, or the battery case is swollen, and follow the manual for service.

Safety tips

• Wear eye protection. Fastener fragments and bit pieces can leave the work.
• Use impact-rated bits. A standard screwdriver bit can shatter in an impact collet.
• Match the bit to the fastener head and do not over-drive into thin or finished material.
• Keep hands, hair, and loose clothing away from the rotating bit.
• Secure the workpiece. An impact driver can still walk a screw if the start is off-center.

Which alternative fits which buyer

• DEWALT DCF887B suits someone who already owns 20V MAX batteries and wants a brushless XR impact as a bare tool.
• Milwaukee 2853-20 suits M18 users who want a FUEL impact and already have packs and a charger.
• RYOBI P238 suits ONE+ owners who want a brushless 1/4-inch impact and will confirm whether that listing is tool only.
• CMCF800C1 suits a buyer who wants CRAFTSMAN V20 fastening power with the battery and charger in the same box.

Who should consider buying it?

Consider the CMCF800C1 if you want a 1/4-inch cordless impact driver for home repairs, furniture, and general fastening, and you do not already own another battery system. The included 1.5Ah battery and charger are the practical reason to choose this kit over a bare pro tool.

Who might prefer an alternative?

Prefer another tool if you need brushless runtime, a second battery in the box, or you already standardized on DEWALT, Milwaukee, or RYOBI. Also look elsewhere if the job is drilling, masonry, or high-torque automotive work.

Final verdict

The CRAFTSMAN CMCF800C1 is a straightforward 20V MAX impact driver kit for homeowners and light maintenance work. Its strengths are the included 1.5Ah battery and charger, the 1/4-inch quick-release chuck, the LED, and published fastening specs of 1,460 in-lbs and 2,800 RPM. Its limits are the brushed motor, a single small pack, and the fact that bits are not part of the manufacturer includes list. Buy it if you want to start fastening on the V20 system without a separate battery purchase. Skip it if you need brushless power or you are already committed to another battery platform.
