Types Explained
Corded Angle Grinders
Plug into a wall outlet for unlimited runtime and consistent power. Typically heavier but cheaper and more powerful.
- No battery runtime limits
- Higher amps / torque available
- Lower upfront cost
- Tether limits mobility
- Heavier than cordless
Best for: Garage workshops, continuous grinding, and budget buyers.
Example: BLACK+DECKER BDEG400 ($46)
Cordless Angle Grinders
Battery-powered for portability. Usually more expensive but ideal for remote jobs.
- Fully portable
- Can be used anywhere without power
- Battery and charger cost extra
- Shorter runtime under load
Best for: Construction sites, outdoor projects, and quick touch-ups.
Example: DEWALT DCG413B ($157)
Compact / Lightweight Grinders
Smaller frame and lower weight for maneuverability in tight spaces.
- Easy to handle one-handed
- Less fatigue over long periods
- Usually lower power (amps or voltage)
- Smaller discs limit depth of cut
Best for: Tight corners, overhead work, and lighter tasks.
Example: Metabo HPT G12SR4 ($59)
What Actually Matters
| Factor | Importance | Best brand |
|---|---|---|
Power (amps for corded, voltage for cordless) Corded: ≥6A for light tasks, ≥11A for heavy. Cordless: ≥20V. More amps mean faster cuts and less bogging. For occasional use, 6A is fine. | Must-have | DEWALT (11A corded, 20V cordless brushless) |
RPM (rotations per minute) ≥10,000 RPM for general grinding; ≥12,000 for fast cutting. Higher RPM cuts faster but may generate more heat. 12,000 is the sweet spot. | Must-have | Metabo HPT (12,000 RPM in a lightweight package) |
Weight Under 5 lbs for comfortable one-handed use. Heavier grinders (6+ lbs) cause fatigue on long jobs. Lighter is better for precision. | Nice-to-have | Metabo HPT (4.0 lbs) |
Safety features (brake, kickback protection) Look for electronic brake (stops disc in ≤2 sec) and anti-kickback. A brake prevents the disc from spinning after shutoff — critical for safety. | Must-have | DEWALT (2-sec brake and Kickback Brake on DCG413B) |
Corded vs Cordless Cordless: 20V+ battery platform required. Corded: 120V outlet. Cordless adds $60-100 for battery & charger. Corded is cheaper and never runs out of power. | Must-have | DEWALT (best cordless ecosystem) |
Brand name alone Don't pay extra just for a logo. Rebadged tools often match performance at half the price. | Marketing BS | — |
Included accessories (wheels, case) Accessories are cheap to buy separately. A carrying case is nice but not worth a premium. | Marketing BS | — |
Budget Tiers & Top Picks
What to buy at each price point — and exactly where spending more stops paying off.
Budget (Under $50)
$36 – $46
Stop paying more: Diminishing returns above $50. For occasional home use, this 6.0A grinder is all you need.
When to upgrade: Need a corded model with more power? Step up to the $59-94 mid tier.
Mid ($50 – $100)
$59 – $94
Stop paying more: At $59, this gives you 12,000 RPM and a compact 4.0 lb design. Spending more than $100 doesn't add much for light/medium tasks.
When to upgrade: Need more power or cordless convenience? The premium tier adds brushless motors and batteries.
Premium ($100 – $160)
$137 – $157
Stop paying more: At $157, you get brushless motor, 2-sec brake, and kickback protection. Above $200 is overkill for most homeowners.
When to upgrade: Need even more power? Consider a corded 11A model like DEWALT DWE402 at $94.
Common Mistakes to Avoid
Buying a grinder with too many accessories you won't use
Many budget grinders come with 10+ discs and a case—but discs are cheap and you'll likely replace them with better ones.
Cost of getting it wrong: Paying $10-20 extra for accessories that sit in a drawer.
Overpaying for brand name alone
DEWALT and Milwaukee are excellent, but brands like BLACK+DECKER and Metabo HPT offer similar performance at half the price.
Cost of getting it wrong: Wasting $30-60 on branding when a lesser-known brand would suffice.
Ignoring disc compatibility (arbor size)
Most angle grinders use 7/8" arbor with 5/8"-11 threaded spindle, but some specialty grinders use different sizes.
Cost of getting it wrong: Buying incompatible discs means additional cost for adapters or returns.
Neglecting brush life on corded models
Corded motors have carbon brushes that wear out. Models with auto-off brushes (like DEWALT DWE402) save damage.
Cost of getting it wrong: Replacing a burnt motor costs more than brush replacement ($5-10).

Frequently Asked Questions
Which angle grinder should I buy for cutting metal?
For metal cutting, look for a grinder with at least 6 amps (corded) or 20V (cordless) and 10,000+ RPM.
What is the best cordless angle grinder?
Its brushless motor delivers runtime comparable to corded models, and the 2-second brake and kickback protection are class-leading. It's a bare tool, so you'll need a DEWALT 20V battery.
What is the best budget angle grinder?
It has a metal gear case, 6.0A motor, and three-position side handle. For a complete starter kit, the AVID POWER 7.5A at $37 includes 5 wheels and a case.
Which grinder is best for grinding concrete?
For concrete, you need high power—at least 11 amps corded. Use a diamond cup wheel for best results.
What is the most powerful angle grinder?
It's corded, so no battery concerns.
What is the best angle grinder for DIY home projects?
It's affordable, durable, and handles cutting and grinding around the garage.

What should I look for when buying an angle grinder?
Focus on power (amps for corded, voltage for cordless), RPM (10,000+), weight (under 5 lbs for comfort), and safety features like a brake. Don't overpay for brand or excessive accessories you won't use.
Is a corded or cordless angle grinder better?
Corded grinders offer unlimited runtime and more power per dollar. Cordless ones provide portability and are ideal for remote work. Choose cordless if you already own a compatible battery system, otherwise corded is more practical.
