Bosch GWS 800 Angle Grinder: Attachments, Accessories & Price Guide

What is the Bosch GWS 800 Angle Grinder

The Bosch GWS 800 is an 800W professional-grade angle grinder built for cutting, grinding, and surface prep work on metal and other hard materials. It sits in Bosch's entry-level professional lineup, meant for both site professionals and serious home users who need reliable performance without paying for a bulkier, higher-wattage machine. I've run this tool through cutting mild steel sheets, deburring welded joints, and light surface grinding, and it handled all of it without breaking a sweat.

Core Features That Matter in Real Use

• 800W motor with 11,000 RPM: This combination is what makes the GWS 800 professional angle grinder feel snappy. In my testing, it chewed through 3mm MS sheet cutting without bogging down, something budget grinders often struggle with.
• 100mm disc size: Smaller than the 115mm or 125mm grinders, this size gives you better control in tight corners, railings, and fabrication work, though it limits how much material you can remove in one pass.
• M10 spindle thread: This is the standard thread size for most 100mm discs and attachments sold in India, so you won't struggle to find compatible accessories.
• 1.7 kg weight: Noticeably lighter than most 4-inch grinders in this price bracket. After an hour of continuous grinding, my wrist fatigue was much lower compared to heavier machines I've used before.
• Dust-resistant build and safety guard: The sealed motor housing kept dust out even during dry cutting sessions, and the guard stayed firmly in place through repeated angle adjustments.

Attachments and Accessories You Can Use

One thing buyers often ask is what angle grinder attachments actually work with the GWS 800. Since it uses a standard M10 spindle thread, you get decent flexibility here.

• 100mm angle grinder discs: Cutting discs, grinding discs, and flap discs in 100mm size fit directly. Stick to genuine or well-reviewed third-party discs rated for the grinder's RPM.
• 100mm angle grinder sanding discs: With a backing pad attachment, you can convert this into a sander for wood or metal surface finishing. It's not a dedicated sander, but it works fine for occasional use.
• Angle grinder wood cutting attachment: Wood cutting blades designed for angle grinders do fit, but I'd recommend caution here. These blades are aggressive and the grinder wasn't originally designed for wood cutting, so use a proper guard and go slow.
• 100mm angle grinder saw blade for wood: Similar to the wood cutting attachment, these are available in the market and compatible by thread size, but treat them as an occasional-use accessory rather than your primary wood-cutting tool.
• Angle grinder stand: If you're doing repetitive precision cuts, a bench-mounted stand attachment can convert this handheld grinder into a mini cut-off station. It's a genuinely useful add-on for small fabrication setups.

Benefits of Choosing the GWS 800

The biggest benefit I noticed is the balance between power and control. Many budget grinders either lack sufficient RPM or feel too heavy for extended use. The GWS 800 professional angle grinder manages to stay light while still delivering enough torque for real cutting work, not just light hobbyist tasks.

It's also a practical choice if you're building a multi-purpose toolkit at home. With the right discs, it handles metal cutting, deburring, rust removal, and light sanding, saving you from buying multiple single-purpose tools.

Value for Money

At its current price point, the Bosch GWS 800 price sits competitively against other 800W angle grinders from brands like Dewalt, Ryobi, and Dongcheng. Compared to a Dewalt 800w angle grinder or Ryobi 800w angle grinder, Bosch's advantage is mainly in build consistency and easier availability of spare parts and discs across India. You're not just paying for the brand name; the fit and finish, motor durability, and after-sales network genuinely add value here.

If you compare it to the Bosch angle grinder 750w models, the GWS 800 offers a meaningful power bump for a relatively small price difference, which makes it the better pick for anyone doing more than occasional light-duty work.

Pros and Cons

• Pro: Strong power-to-weight ratio, so you get real cutting performance without excessive arm fatigue.
• Pro: Wide availability of Bosch GWS 800 spare parts and discs across online and offline stores in India.
• Pro: M10 thread compatibility opens up a large range of attachments beyond standard discs.
• Pro: Compact 100mm disc size makes it easier to work in tight spaces compared to bigger grinders.
• Con: Smaller 100mm disc means slower material removal on large surface jobs compared to 125mm grinders.
• Con: Not designed primarily for wood cutting, so using wood attachments requires extra caution and isn't ideal for heavy wood work.

Who Should Buy the Bosch GWS 800

This grinder makes sense for fabricators, metalworkers, and DIYers who need a reliable, lightweight tool for cutting and grinding metal regularly. It's also a solid pick if you want one machine that can handle multiple small jobs around the house or workshop with the help of different discs and attachments.

If your work primarily involves larger surface grinding or heavy wood cutting, you might be better served by a bigger 125mm grinder or a dedicated wood-cutting tool instead.

Is the Bosch GWS 800 Worth Buying

Based on my hands-on use, yes, it's worth buying if you fall into the target use case of metal cutting, grinding, and light fabrication. The build quality, motor performance, and accessory ecosystem justify the angle grinder price you're paying, especially when you factor in Bosch's service network for spare parts down the line.
