The rusted bolt will not budge, the cutoff wheel on the old grinder is worn to a nub, and the mower blade needs an edge before the weekend. That is the moment for the best angle grinder under 100: a corded grinder that cuts, grinds and cleans metal without a big spend. This guide compares five grinders by what their listings state: amps, RPM, included wheels, weight and warranty.
All five picks are 4-1/2 in corded grinders on 120 volts, so the only power question is how many amps each one draws, and the only size question is which discs come in the box. Corded tools skip the battery question entirely: plug in and work until the job is done.

How we scored them
Each grinder is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. None of these listings names a safety certification, so every safety score here is 0. Two listings state a 1-year warranty term, so two warranty scores are above 0. Grinders that bundle wheels, guards and cases earn value points; listings that contradict themselves on weight lose build points.
| Product | Shop Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Metabo HPT G12SR4 Grinder | 9.6 | 29 | 21 | 22 | 0 | 3 |
| Skil 9295-01 Grinder | 9.5 | 27 | 21 | 21 | 0 | 3 |

| Bosch GWS8-45 Grinder | 9.4 | 28 | 21 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
What the listings tell you
We read 5 angle grinder listings. All five are 4-1/2 in corded grinders on 120 volts. Three state 12,000 RPM and two state 11,000. Two state a 1-year warranty term, and none names a safety listing. Two listings contradict themselves on weight, which their reviews call out.
On motors, the range is 6.0 to 7.5 amps and 720 to 980 watts. The AVID POWER, SHALL and Bosch state 7.5 amps, the Metabo HPT 6.2 amps with 980W of max output, and the Skil 6.0 amps with 720 watts. On included wheels, the Metabo HPT brings 5 grinding wheels and a case, the AVID POWER 2 cutting and 2 grinding wheels, and the SHALL 3 cutting wheels plus 3 flap discs; the Bosch and Skil state no included wheels. On guards, the AVID POWER and SHALL state tool-free adjustment, the Skil a tool-less guard, and the Bosch a burst-protection guard; the Metabo HPT states no guard type beyond the included Type 27 grinding guard in its parts list.
Buying guide: best angle grinder under 100
Amps and RPM
Amps and RPM set the pace of the work. Three listings state 12,000 RPM: the AVID POWER and SHALL at 7.5 amps and the Metabo HPT at 6.2 amps. The Bosch and Skil state 11,000 RPM at 7.5 and 6.0 amps. For cutting rebar and grinding welds, the higher RPM picks finish faster; for occasional rust removal, 11,000 RPM is plenty. Note the Metabo HPT’s 980W max output against the AVID POWER and SHALL at 900W and the Skil at 720W: watts and amps together describe the motor better than either alone.
Included wheels and discs
Wheels are where budget grinders differ most. The Metabo HPT includes 5 grinding wheels and a hard case. The AVID POWER includes 2 metal cutting wheels and 2 metal grinding wheels. The SHALL includes 3 cutting wheels and 3 flap discs at 60 grit, plus 2 wheel guards. The Bosch and Skil list no included wheels, so budget a few discs with those two. Flap discs, like the SHALL’s 60-grit three, suit finishing and blending; grinding wheels suit stock removal on welds; thin cutting wheels suit slicing rebar and pipe.
Weight and handling
The stated weights run from 3.64 lb on the AVID POWER and 3.7 lb on the SHALL to 4.0 lb on the Metabo HPT and Skil and 4.2 lb on the Bosch. The AVID POWER spec table says 5.1 lb against its bullets’ 3.64 lb, and the SHALL spec table says 60 g against its bullets’ 3.7 lb; trust the bullets in both cases. A lighter grinder fatigues the arms less on overhead work. Handle design matters as much as weight: the AVID POWER and SHALL state 2-position side handles for left and right hands, the Metabo HPT a forward-canted handle, and the Skil a vibration-reducing handle with wrench storage.
Warranties at this price
Two of the five state a warranty term: the Metabo HPT a 1-year base warranty and the Skil 1 Year. The Bosch spec table says only “Warranty” with no term, and the AVID POWER and SHALL state nothing. At this price a stated year of coverage is a real differentiator, which is why those two lead the ranking. A warranty without a term, like the Bosch’s, earns no points here; only a concrete period counts. That rule is why the Metabo HPT and Skil sit atop the ranking despite not having the biggest motors. When two grinders tie on paper, the one with a stated warranty and a case wins the drawer space.
For the rest of the metal shop, a welding table for the home garage gives the grinder a flat place to work, and cordless vs corded angle grinder covers the battery alternative.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Check your outlet situation: all five are corded 120-volt grinders.
- Match the discs to the job: cutting wheels for rebar, grinding wheels for welds, flap discs for finishing.
- Wear eye protection and keep the guard on; sparks and debris are part of the job.
- Note the warranty picture: only the Metabo HPT and Skil state a 1-year term.
- Plan disc storage; only the Metabo HPT includes a case.
- Unplug the grinder before changing discs, and let the wheel stop before setting the tool down.
- Keep spare brushes with the grinder; two picks include them.
Frequently Asked Questions
What size angle grinder do I need for metal work?
A 4-1/2 in grinder is the standard home-shop size, and all five picks here are 4-1/2 in. The AVID POWER and SHALL state a 7/8 in arbor with a 5/8-11 threaded spindle, which fits most common wheels. Larger 7 in grinders exist for heavy cutting, but they cost more and tire the arms faster.
How many amps do I need in an angle grinder?
The five here run 6.0 to 7.5 amps and 720 to 980 watts. For cutting and grinding metal regularly, the 7.5-amp picks give more headroom; for occasional rust removal and sharpening, 6.0 amps is enough. Amps describe current draw and watts describe power; the Metabo HPT’s 980W max output is the highest power figure here despite its 6.2 amps.
What is the difference between cutting and grinding wheels?
Cutting wheels are thin discs for slicing through metal like rebar and pipe; grinding wheels are thicker for removing welds and rust. The AVID POWER includes 2 of each, the SHALL includes 3 cutting wheels and 3 flap discs, and the Metabo HPT includes 5 grinding wheels. Never use a cutting wheel for grinding: the thin disc can shatter under side load.
Do these grinders come with a case?
Only the Metabo HPT states a hard case. The others state no case, so plan a spot on the shelf or in a tool bag for the grinder and its discs. The AVID POWER and SHALL include spanner wrenches for wheel changes; keep the wrench with the grinder or the next disc change takes twice as long.
Can an angle grinder cut wood?
The SHALL listing mentions metal and wood in its title, and the AVID POWER is aimed at metal and masonry. Standard grinding and cutting wheels are made for metal and masonry; cutting wood with an angle grinder needs a proper wood-cutting disc and care, and none of these listings includes one.
