Compared on paper

Every rating comes from the brand’s listing and is not a shop test (gathered 11 November 2026). Only the WEN listing states a warranty term, and none of the listings states an electrical listing, so safety scores zero across the picks.

How the points were given

Each shear is scored on performance, build, value, safety and warranty, using only what the listing publishes. The weights are on our How We Pick page.

No score drops under 9.2 or climbs past 9.8; a tool’s place inside those bounds is set by its weighted point total.

What the listings tell you

The WTK0040 states a 3 mm / 11 ga capacity for mild steel, the VEVOR guillotine states a 0.08 in / 2 mm thickness, the VEVOR rotary states 16 gauge mild steel, and the WEN and DEWALT listings state 18 gauge. No listing states a 12 gauge mild steel capacity in so many words, so the ranking weighs the stated capacity closest to the job, then the tool itself.

Buying guide: choosing the best metal shear for 12 gauge mild steel

Stated capacity first

Start with the capacity the listing states, not the tool type. The WTK0040 states 3 mm / 11 ga for mild steel, the VEVOR guillotine states 0.08 in / 2 mm, the VEVOR rotary states 16 gauge mild steel, and the WEN and DEWALT listings state 18 gauge. For 12 gauge mild steel, the WTK0040 is the only pick that states a mild steel capacity at 3 mm / 11 ga, while the electric shears are built for thinner sheet.

Electric or manual

Electric shears cut with a trigger pull: the WEN runs a 4 amp motor with a pressure sensitive trigger from 0 to 2500 strokes per minute, and the DEWALT runs a 5 amp motor with a variable speed dial from 100-350 spm. Both heads swivel 360 degrees, so you can follow a line without twisting the tool. Manual shears need arm power, but they need no cord and no outlet, and the throatless picks turn the work at any angle.

Throatless or guillotine

A throatless shear leaves the cutting point open, so the workpiece turns at any angle for straight, curved or irregular cuts. The WTK0040 and the VEVOR rotary both work this way. A guillotine shear cuts straight lines on a bench, and the VEVOR guillotine gives a max cutting length of 12.01 in / 305 mm for longer pieces. Pick throatless for shapes and curves, and the guillotine for straight cuts.

Weight and bench space

The VEVOR rotary weighs 3.97 lb, and the WEN and DEWALT electrics weigh 4.7 lb each, so they travel to the job in a tool bag. The WTK0040 weighs 15.43235834 lb, and the VEVOR guillotine weighs 39.68 lb with dimensions of 24.41 x 15.16 in, so both stay on the bench. Measure your bench before the guillotine arrives.

Blades and care

Blades decide the cut quality. The VEVOR guillotine uses T10 steel blades heat-treated to HRC52-54, the VEVOR rotary uses 40Cr blades heat-treated to HRC52-54, and the WTK0040 uses replaceable 4 in hardened alloy steel blades. The VEVOR listings state a blade gap of less than 0.07 mm. Keep the blades clean, keep hands clear of the cutting edge, and store the shear where the blades cannot catch a sleeve.

Garage Fit Check

• The VEVOR guillotine weighs 39.68 lb and measures 24.41 x 15.16 in, so give it a firm bench with room for the extended handle.
• The WTK0040 has 3 holes for mounting, so bolt it down before you start cutting.
• The WEN trigger runs from 0 to 2500 strokes per minute, so start slow until the cut feels right.
• Check the stated capacity against your steel before you buy: the WEN and DEWALT listings state 18 gauge, and the VEVOR rotary states 16 gauge.
• Store the shear where the blades cannot catch a sleeve, and keep hands clear of the cutting edge.

FAQ: garage tools

Can an 18 gauge electric shear cut 12 gauge mild steel?

Not per the listings: the WEN and DEWALT listings state 18 gauge, and neither states 12 gauge. The WTK0040 states 3 mm / 11 ga for mild steel, which is the pick that names the thicker material.

What is a throatless shear?

A throatless shear has no frame around the cutting point, so you can turn the workpiece at any angle for straight, curved or irregular cuts, per the WTK0040 listing. The VEVOR rotary shear cuts straight lines, curves and more complex shapes.

Do I need a bench shear or a handheld shear?

A bench shear like the VEVOR guillotine suits straight cuts in longer pieces, with a max cutting length of 12.01 in. A handheld electric shear suits curves and cuts on the car, with a swivel head that rotates a full 360 degrees.

How heavy are these shears?

The VEVOR rotary weighs 3.97 lb and the WEN and DEWALT electrics weigh 4.7 lb each. The WTK0040 weighs 15.43235834 lb, and the VEVOR guillotine weighs 39.68 lb, so it stays on the bench.

Do any of these shears come with a warranty?

Only the WEN listing states a warranty term: 2 years. The other listings state no warranty term.
