Craftsman V20 CMCD700C1: problems, parts and running costs

Checked: 2026-10-17

Summary

The CMCD700C1 kit’s standing limits are the small 1.3 Ah battery and heavy drilling: in independent testing the pack finished four drilling cycles per charge, where the top drills in the group exceeded ten, and a full recharge took 58 minutes, while a 5-inch hole saw left the side vents uncomfortably hot. Owner reports add chuck slip and wobble, plus one kit that arrived without its chuck. Electricity runs about $0.33 a year at 50 charge cycles, and the real extra cost is a $49 spare battery when one pack is no longer enough. It is a good buy at $50-$60 all-in before tax and acceptable at $65-$80 for owners already on the V20 platform, but weak at $90-$100 once the spare battery is priced in.

Common problems and fixes

Battery drains fast and charging stops work — TechGearLab’s 2022 test of the exact kit ran four full cycles of repeated drilling on the included 1.3 Ah pack, almost a fifth, where the leading drills in the group exceeded ten, and a full charge took 58 minutes; with one pack in the box, work stops while it charges. The workaround is a second battery, and the 3-year limited warranty covers defects in materials and workmanship rather than battery wear. [3][9]
Stalling and hot exhaust under heavy drilling — a 5-inch hole saw took about 55 seconds, the high gear bound and low gear was needed to finish, and air from the side vents became uncomfortably hot; a 1/2-inch bit through 16-gauge steel took 5-7 seconds and sometimes bound as it broke through. Use low gear for large holes and let the tool cool between attempts. [3]
Large lag screws stall — the tester’s largest lag screw was left about 5/8 inch proud, so repeated big lag fastening belongs on an impact driver or a more capable drill. [3]
Chuck slips or wobbles — owner reports describe bit slip after tightening, runout within two years, and one tool that seized after five holes, with no failure rate published; if the chuck slips or wobbles, stop running large bits and contact service. One August 2026 report says CRAFTSMAN arranged a replacement part for a kit that arrived without a chuck. [4][8]
Work light is shadowed — the LED above the trigger is partially blocked by the chuck at the drilling point, so a separate work light helps in dark cabinets. [3]
Brushed motor, no hammer mode — the brushed motor runs hotter than brushless alternatives under tough work, and the drill has no hammer mechanism, so masonry means carbide bits, light pressure, or a separate hammer drill. [1][2]

Parts and consumables

V20 battery, 1.3 Ah — the pack included in the kit; the product title says 1.5 Ah but the official kit breakdown and the tested kit say 1.3 Ah. No fixed replacement interval, and the manual says the battery and charger have no user-serviceable internals; replace when it stops holding a charge. [1][2]
CRAFTSMAN CMCB202 2.0 Ah battery — $49 at Lowe’s (2026-10); CRAFTSMAN rates it at up to 1.5x the runtime of the 1.3 Ah pack, though not on every workload. Replace on condition, not on a schedule. [5][10]
CRAFTSMAN CMCB104 charger — listed separately at $99 at Lowe’s (2026-10), which is more than a complete kit is worth in most cases; the exact charger bundled in the box is not confirmed to be this model. [6]
Double-sided screwdriver bit — one is included and the kit does not include a drill-bit set; replace bits when they are dull, bent or damaged. [1]

Yearly running cost

There is no subscription and no fixed annual parts schedule. Illustrative electricity calculation: a 1.3 Ah, 18 V pack holds 23.4 Wh nominal; at an assumed 70% wall-to-battery charge efficiency, each full-capacity replenishment is about 0.0334 kWh, so 50 cycles a year comes to about 1.67 kWh, or $0.33 at an assumed $0.20/kWh. That is an illustration, not a measured draw. [1][2]

A second battery is a one-time $49 purchase at Lowe’s (2026-10), not an annual expense; amortized over a hypothetical three years it would be $16.33 a year, but the real pack lifespan was not established. The only other regular cost is worn or damaged bits. [5]

When it is a good buy

$50-$60 all-in before tax — good beginner buy if one battery is enough for your projects.
$65-$80 — acceptable when you already own V20 batteries and want the full kit.
$90-$100 — weak without a second battery: a $99 purchase plus the $49 spare costs $148 before tax, more than the $129 Ryobi ONE+ HP brushless kit at Home Depot (2026-10), which includes a 2.0 Ah battery and charger. [14]
Above $100 — favor a newer brushless kit or a platform you already own.

Retail pricing for this exact kit is inconsistent: Ace Hardware has indexed $99 regular with a $59 Ace Rewards promotion, but that snapshot predates this page and the promotion is not confirmed active; Lowe’s shows a price only after entering a store or ZIP code; HomeBase USA reported $99 in stock in October 2026.

Alternatives:

Ryobi ONE+ HP PBLDD01K1 brushless kit — $129 at Home Depot (2026-10); the better choice when you want more power and runtime than the 280 UWO brushed motor delivers. [14]
CRAFTSMAN V20 CMCD702D1 2.0 Ah kit — a newer same-platform kit that comes with a larger factory battery instead of a separate $49 pack. [13]
