Side by side

Specs are the manufacturer’s ratings as listed, collected 4 November 2026.

How corded vs cordless cut off tool power compares

Power is stated in different units on each side. The DCA example lists 7.2 Amp at 860W and 11,800 RPM, the DEKOPRO example lists 8-Amp at 900W and 12,000 rpm, the TEENO example lists 16.8V at 500W and 19,500 RPM, and the ZFULVO example lists 16.8V at 19500 rpm. A higher speed figure alone does not decide the side.

Disc size and tight corners

The corded examples both use 4-1/2 inch discs, while the TEENO cordless example uses 3 inch discs. The TEENO listing says its shorter gear head reaches awkward corners where larger 4-1/2 inch tools do not fit. The ZFULVO listing does not state a disc size, so that figure stays unclear.

Weight, kit and power source

Only two listings state a weight: the DCA example at 3.53 lbs, and the ZFULVO example at 1100g in its bullets, while its spec table states 3.63 Pounds, so the bullet figure is used here. The DEKOPRO and TEENO listings do not state a weight. Corded kits include guards, discs and handles, while cordless kits include 2 batteries each, a charger and discs, plus a hard case and gloves for the TEENO example.

Garage Fit Check

• Check disc size first: 4-1/2 inch for the corded examples, 3 inch for the TEENO example; the ZFULVO listing does not state one.
• Check power: corded examples need mains power, cordless examples need chargers and 2 batteries each.
• Check storage: only the TEENO example states a hard case.
• Check guards before cutting: 2 guards for the DCA example, a wheel guard and a cutting guard for the DEKOPRO example, and an adjustable base guard and a widened cutting guard for the TEENO example.

FAQ: garage tools

Which side suits cutting metal for long jobs?

The corded examples suit long jobs plugged in, with no battery to swap: the DCA example lists 7.2 Amp at 860W, and the DEKOPRO example lists 8-Amp at 900W.

Do the cordless examples cut faster?

Speed alone does not answer that. The TEENO example lists 19,500 RPM and the ZFULVO example lists 19500 rpm, against 11,800 RPM for the DCA example and 12,000 rpm for the DEKOPRO example, but disc sizes and motors differ too.

What disc size does each side use?

The corded examples use 4-1/2 inch discs, and the TEENO cordless example uses 3 inch discs. The ZFULVO listing does not state a disc size, so that figure stays unclear for that example.

What do the cordless kits include?

The TEENO example includes 2 batteries at 2.0Ah each, a charger, 6 discs, gloves and a hard case. The ZFULVO example includes 2 batteries at 2000mAh each, a fast charger, 6 cutting discs, 2 wrenches and a glove.
