If you’re after a no‑nonsense mid‑size grinder that tackles everyday metal and masonry work without fuss, the DEWALT DW801‑IN 4‑inch Heavy Duty Angle Grinder is legit. This isn’t some toy you stick in the corner — it’s got a gutsy, corded 850 W motor that doesn’t quit when you’re cutting, grinding, or removing rust off thick stock.

Here’s the thing: with a 100 mm (4″) disc diameter you get the size that tradespeople reach for every single day because it’s small enough to wriggle into tight spots but still big enough to shift material fast. It’s been built with the basics you really need — spindle lock for quick wheel changes and a handle you can swap to either side — so you’re not wrestling the tool trying to get the job done.

Key Features:

• 850 W Motor - Cranks out enough power to chew through steel, rebar, tile and more without bogging down.
• 100 mm Disc Size - Compact disc that’s ideal for both cutting and grinding in tight spaces.
• Spindle Lock - Lets you change discs fast — no mess, no hassle.
• Side Handle - Gives you a solid two‑hand grip so you can stay in control when the work gets rough.
• Toggle/Slide Switch - Simple on/off that doesn’t overcomplicate an already tough tool.

Applications

In practice, the DEWALT 4‑inch grinder is perfect for cutting through metal pipe on site, prepping welds, cleaning up mortar joints, and taking burrs off fabricated parts. It’s the grinder you’ll pop out for when angle and accessibility matter — like trimming tile edges in a tight corner or grinding weld seams on a frame.

Why Choose This Model

Look, there’s a lot of little grinders out there — but what really stands out with this one is how it hits the sweet spot between brute power and everyday usability. The heavy duty build means you aren’t babying it in the workshop, and that 850 W motor will shrug off jobs that would stall smaller units. The weight and balance feel right — not too front‑heavy, not floppy — so you actually enjoy using it even during longer sessions.

Technical Specifications Explained

• Power Input (850 W) - Enough juice to keep the tool cutting smoothly through tough materials without overheating.
• No‑Load Speed (~11,000 RPM) - Spins the wheel fast so cuts are clean and grinding is efficient.
• Disc Diameter (100 mm) - A size that’s versatile — big enough for material removal but small enough for detail work.
• Spindle Thread (M10) - Standard thread size means you can fit a wide range of aftermarket discs.
