1. Furniture Restoration with Cordless Angle Grinder: Economical Solutions

Furniture restoration is pretty easy with a cordless angle grinder. Here are five ways you can accomplish this.

Scene 1: Refinishing an Old Wooden Table

A cordless angle grinder with a flap disc is a powerful tool for refinishing an old wooden table. It can prepare the surface, for example.  
Here's how your angle grinder can be effectively used. Use a flap disc (80-grit to start), and you'll strip that old in half the time it takes to hand sand. Work in the direction of the wood grain, keeping the grinder moving to avoid gouges. Once you hit bare wood, switch to 120-grit for a smooth finish that's ready for staining.

Scene 2: Restoring a Rusty Metal Chair

A cordless angle grinder can effectively handle metalwork tasks. For instance, you can effortlessly remove rust and give it a new shape.
Do you have a vintage metal patio chair that's seen better days? Your angle grinder with a wire cup brush will make quick work of that rust. Start at the most heavily rusted areas and work your way around. Keep the grinder at a 15-degree angle; this gives you the best contact without being too aggressive. Once the rust is gone, smooth out any rough spots with a flap disc before painting.
This ONEVAN 125mm Brushless Cordless Angle Grinder can easily handle tough tasks. Its cordless design lets you move freely, and the brushless motor gives it power. You can change speeds for sanding wood or removing rust from metal. The 125mm disc works with different tools, like brushes and sanding discs.

Scene 3: Refinishing a Wooden Armchair

Ornate armchairs with curved details are usually a pain to refinish—but not with your cordless grinder.  In this scenario, a cordless angle grinder can make your work very easy and allow you to execute your work with more precision. Grab a detailed sanding pad attachment and you can get into those tight spots around the arms and back. Start with coarse grit in the really rough areas, then work your way up to finer grits. The trick is using light pressure and letting the tool do the work.

Scene 4: Transforming an Old Wooden Box into a Storage Bench

A cordless angle grinder can fix a lot of old items in your home. With an angle grinder, you can easily make more precise and accurate cuts.

Ready to tackle those tile projects you've been putting off? Your cordless angle grinder can handle the job - and yes, it's easier than you think. Here's how to master five common tile-cutting challenges:

Scene 1: Cutting Tiles to Fit Kitchen Counter Edges

You want to achieve an attractive look for kitchen tile edges. If you use a proper diamond cutting wheel with your cordless angle grinder, you can easily master the task.
Cutting Tiles to Fit Kitchen Counter Edges. Ever wonder how pros get those perfect counter edge cuts? Here's the setup:
Diamond cutting wheel (continuous rim for porcelain, segmented for ceramic)
Speed square for marking
Painter's tape to prevent chipping
Splash bottle for dust control
Mark your cut line with tape, mist the tile with water, and make steady passes. Pro tip: Cut halfway through from the top, then flip the tile and complete the cut from the opposite side. You'll get cleaner edges every time.

Scene 2:  Remodeling Bathroom Wall Tiles

Remodeling bathroom wall tile cuts don't have to be a headache. You can easily remodel bathroom tiles and achieve precise cuts with an angle grinder.
You'll need:
Diamond wheel
Cardboard template for odd shapes
Marker for transfer lines
Safety goggles (tile dust is no joke)
Start with a full-size template of your cut area. Transfer it to your tile, then take it slow - rushing wall cuts is asking for trouble. Work in sections, keeping the blade wet for smooth cutting and longer wheel life.

Scene 3: Replacing Bathroom Floor Tiles

Floor tiles need special attention because everyone sees them. Their surface can fade with time. However, a cordless angle grinder can give you professional-grade results.
Grab:
Fresh diamond wheel (dull blades = rough cuts)
Straight edge
Non-slip mat to hold tiles
Dust mask
Here’s the trick: First, score the glaze with a light pass, then make your full-depth cut. This technique prevents chipping at the edges of the tiles. For long cuts, use your straight edge as a guide - your grinder will follow it like a track.

Scene 4: Cutting Tiles for Pipe/Outlet Installation

Circular cuts that may appear challenging can be accomplished with the right cordless angle grinder.  You'll want:
Diamond wheel
Compass for marking circles
Plunge cutting technique
Extra patience (this one takes practice)
Mark your circle, then make relief cuts from the edge to your line - think pizza slices. Then connect the dots around your circle. Take your time here - rushing circular cuts is a recipe for cracked tiles.

Scene 5: Carving Decorative Patterns on Tiles

Do you want to be creative and draw some patterns? In this scenario, a cordless angle grinder with the right attachment can give significant results.
Here's what you need:
Diamond point bit
Pencil for pattern transfer
Variable speed control
Light touch
Start with simple patterns—straight lines or basic curves. Keep your speed low and pressure light. The secret is multiple gentle passes rather than one heavy cut. Once you've mastered the basics, try more complex designs.

3. Artistic Creations with Cordless Angle Grinder: Metal Sculptures and Functional Pieces

You can accelerate your artistic creations by incorporating a cordless angle grinder effectively. Here are fine scenes.

Scene 1: Creating Metal Sculptures

Let's transform that cordless grinder into your personal sculpting tool. Start with your basic setup: You'll want a 4½-inch cutting wheel for precise cuts paired with 40- and 80-grit flap discs for shaping and smoothing. A wire wheel is essential for creating the organic textures that make metal art come alive.
When you're ready to cut, begin with the larger shapes. Here's a pro secret: always leave about 1/8 inch extra - you can always grind away more, but you can't add metal back. Run your grinder at about 75% speed for better control.
The magic happens in the detail work. Switch to that 40-grit flap disc for defining edges, working in small sections no larger than 6x6 inches at a time. Create depth by layering pieces - this is where metal art really starts to pop.
Want to create some eye-catching effects? Try the basket weave look by cross-hatching with your wire wheel. For a raindrop effect, make quick touches with your grinding wheel. Tree bark textures come alive with irregular passes using a coarse disc, while a moon surface emerges from random circular motions.

Scene 2: Designing Functional Metal Furniture

 Functional art starts with the right materials and a good battery operated angle grinder. One-inch square tubing creates rock-solid frames, while 1/8-inch plate steel makes perfect tops. Keep various thicknesses of flat bars handy for those creative details that set your work apart.
Start with your frame construction. Those 45-degree angles need to be spot-on for corners - no gaps allowed here. Test fit everything before making your final cuts. Here's a secret that separates pros from amateurs: clean those joints thoroughly with a wire wheel before welding.
For surface treatments, start with 40-grit to establish your texture, then move to 80-grit to achieve a finer finish. The key is maintaining consistent pressure as you work.

Scene 3: Crafting Metal Collage

Metal art collage involves combining different metals for visual impact. However, an angle grinder can significantly save time and effort.
Copper paired with steel creates a stunning rust patina, while brass and aluminum offer bright contrasts that catch the eye. For a classic look, try steel with bronze, or go modern with stainless and copper combinations.
Your base layer needs to be sturdy—think 1/8-inch minimum thickness. Create your anchor points first, then texture the entire surface before adding details. For your overlay pieces, 22-gauge metal works perfectly. Bend those edges to add dimension, secure everything with tabs or welds, and blend your transitions with a fine flap disc.

Scene 4: Adding Textures and Surface Effects

A cordless angle grinder is undoubtedly a good tool for cutting and grinding, but it can also be used to add textures and surface effects.
Texturing metal allows your grinder to act like a precision tool. Work with a wire cup brush fitted with 0.020-inch wire for basic effects, then graduate to diamond burr bits for finer details.
For swirls, adjust your grip based on the desired effects, making steady circles with the grinder. Straight lines need consistent speed - any variation shows up in your final piece. Want to create water ripples? Try overlapping arc motions. Wood grain effects emerge from long, wavy passes.

Scene 5:  Customizing Metal Signs

Making custom metal signs requires a wise selection of materials. It also requires precision. You can incorporate a cordless angle grinder to achieve professional results.
Customizing Metal Signs Sign-making requires the right material choices. Sixteen-gauge steel offers durability that will last for years, while 1/8-inch aluminum keeps things lighter. Brass is hard to beat for that elegant touch. Achieving professional-looking signs starts with thorough preparation. Take time to create clean templates, and never rush your cutting—steady hands make straight lines.
