Craftsman CMCF800C1: problems, parts and running costs

Checked: 2026-10-17

Summary

The CMCF800C1 is the entry brushed-motor V20 impact driver kit: 1,460 in-lbs of torque, 2,800 RPM and 3,100 IPM, single speed, with one 1.5Ah battery and a charger, and no bag or bits. Its limits are the brushed motor, the smallest V20 battery CRAFTSMAN sells, and the absence of any independent instrumented test of this exact model. At $99 (Ace Hardware and McCoy’s, October 2026) it is a reasonable first impact driver for a household; at $119 or more the brushless CMCF830 kit at $168.99 is the stronger step up.

Common problems and fixes

Brushed motor — runs louder, less efficiently and for a shorter life than a brushless tool; no service-parts catalog was found for this model, so repairs are not documented. [1]
Smallest V20 battery — the included 1.5Ah pack is the smallest CRAFTSMAN sells, and CRAFTSMAN does not flag battery life on the kit page; heavy daily use will outrun it, so budget another V20 battery for all-day work. [1]
Single speed — no speed modes or torque selector. [1]
Battery capacity listing disagreement — McCoy’s lists the kit battery as 1.3 Ah while CRAFTSMAN, Ace Hardware and Acme Tools state 1.5 Ah; treat 1.5 Ah as correct. [6][1][4][5]
No bag or bits in the kit — the box holds only the driver, battery and charger; buy a bag and bits separately. [1]

Parts and consumables

V20 1.5Ah Li-ion battery (included) — the smallest V20 pack; shared across the platform, with replacement V20 batteries sold individually. [1]

No consumables (such as bits) are included, and no service-parts catalog was found for the tool.

Yearly running cost

Not enough data.

When it is a good buy

$99 at Ace Hardware and $99.99 at McCoy’s (October 2026): reasonable for a first household impact driver or an add-on for someone already on V20 batteries. [4][6]
At $119 or more the case weakens against CRAFTSMAN’s own brushless CMCF830 kit ($168.99 in 2025) with 1,800 in-lbs, 3-speed control and independent test coverage. [3]
Below $80 on sale it is a strong budget entry, with the 3-year limited warranty and platform compatibility as the differentiators. [1]

Alternatives:

CRAFTSMAN CMCF830 brushless kit, $168.99 (2025) — the better choice when you want more torque (1,800 in-lbs), 3-speed control and independently tested performance. [3]
A larger V20 battery — the better choice than a second kit if you need all-day runtime from the CMCF800C1. [1]
