Which one should you choose?

Choose Cerycose 1/2" Brushless 1700 ft-lb Wrench if

  • You need high torque for heavy-duty tire removal or construction.

  • You want a complete kit with batteries and charger included.
  • You need both an impact wrench and a ratchet for general maintenance.
  • You prefer a lighter, more compact tool for tight spaces.

Verdict: Choose the Cerycose 18V model if you require serious torque for professional or heavy automotive work and already have compatible batteries. Select the ACDelco 12V kit if you need a versatile, ready-to-use set with both impact and ratchet functions for lighter tasks. The 12V option is better for general maintenance, while the 18V unit is built for demanding jobs.

18V vs 12V Impact Wrench Specs

Voltage and Power

Edge: Cerycose 1/2" Brushless 1700 ft-lb Wrench

The Cerycose tool operates on an 18V platform, while the ACDelco kit uses a 12V Max system. Higher voltage generally supports higher torque output for demanding tasks. Cerycose lists a maximum torque of 1700 ft-lbs, suitable for heavy-duty automotive work like tire removal. ACDelco specifies 90 ft-lbs for its impact wrench, which is adequate for lighter fastening and ratcheting duties. You should choose 18V if you frequently tackle stubborn bolts or large fasteners. The 12V option is better for precision work where excessive power might strip threads or damage components.

Included Tools

Edge: ACDelco G12 12V 3/8-Inch Cordless Impact & Ratchet Kit

You get two distinct tools in the ACDelco package: a 3/8-inch ratchet wrench and a 3/8-inch impact wrench. This combination covers a wider range of standard mechanical tasks without needing to swap bits or adapters frequently. The Cerycose listing describes a single impact wrench unit. It does not include a ratchet in the standard bare-tool configuration. If you need both driving and ratcheting capabilities in one purchase, the ACDelco combo provides immediate versatility. You would need to buy a separate ratchet for the Cerycose setup.

Chuck Size

Edge: Cerycose 1/2" Brushless 1700 ft-lb Wrench

The drive size determines which sockets fit your tool directly. Cerycose features a 1/2-inch chuck, the standard for heavy-duty impact applications. It accepts large sockets commonly used for lug nuts and structural bolts. ACDelco uses a 3/8-inch drive, which is common for general automotive repair and lighter mechanical work. While you can use adapters, the 3/8-inch drive limits the size of sockets you can attach directly. For heavy construction or tire service, the 1/2-inch drive on the Cerycose tool is the more practical choice for durability and socket availability.

Motor Type

Edge: Cerycose 1/2" Brushless 1700 ft-lb Wrench

Cerycose specifies a brushless motor in its features list. Brushless motors offer longer lifespan, reduced maintenance, and improved efficiency compared to brushed designs. They also typically provide better speed control and heat management. The ACDelco specifications do not explicitly state the motor type, though it is a cordless lithium-ion tool. Without this specific detail, the Cerycose tool has a clear technical advantage in modern motor technology. You benefit from potentially longer run times and sustained performance with the brushless design on the Cerycose unit.

Battery Included

Edge: ACDelco G12 12V 3/8-Inch Cordless Impact & Ratchet Kit

Battery availability affects your immediate usability. The ACDelco kit includes a 12V Li-ion battery and a fast charger, allowing you to start working right out of the box. Cerycose is sold as a bare tool only, meaning it does not include a battery or charger. You must already own compatible Milwaukee 18V batteries or purchase them separately. If you are building a new tool collection or lack existing batteries, the ACDelco kit offers a complete solution. Existing Cerycose users with Milwaukee batteries will find the bare tool more cost-effective.
