Grinding Cutting Diamond Blade 4-1/2ft 115mm - Dual-Sided Grinding

In this review of the Grinding Cutting Diamond Blade 4-1/2' (115mm) the bottom line is simple: this is a practical, aggressive dual-purpose wheel for tradespeople who need one blade that can both cut and grind hard stone materials. The tester found the vacuum-brazed diamond on both faces makes the wheel durable for roughing and shaping, and the 5/8-11 thread fits standard angle grinders so it can be swapped in without adapters. If you regularly shape porcelain, tile, or granite and want to consolidate tools, this wheel delivers clear value.

Key Features

• Dual-sided design: Vacuum-brazed diamonds on both surfaces let you use the wheel for cutting and then flip it to keep full diamond life for grinding tasks.
• Compact 4-1/2' diameter: The 115mm size works well on standard angle grinders for access to edges and corners without excess weight.
• Thick diamond height: A 26mm diamond layer gives aggressive material removal and better life during rough shaping and beveling.
• Coarse 40/50 grit: The grit grade is tuned for fast cutting and shaping of porcelain, ceramic, marble, and granite rather than fine polishing.
• Wide compatibility: Standard 5/8-11 thread fits most grinders and is recommended to run at about 8000 RPM (max 13200 RPM) for safety and consistent performance.

Who It's For

The wheel is a good fit for tile installers, stonemasons, and DIYers who do frequent edge finishing, beveling, or shaping of hard stone materials and want a single aggressive disc that handles both cutting and grinding. Its compact 4-1/2' size and 5/8-11 thread make it easy to use with common angle grinders on-site.

It is not aimed at users seeking fine polishing or very delicate finish work; for final polish steps one should use finer grit polishing pads or specific polishing wheels. Also, if you need a larger cutting diameter for deep cuts, a bigger blade would be required.

Pros & Cons

Pros

• Dual-sided vacuum-brazed diamonds extend usable life by allowing both faces to be used for rough work.
• Robust 26mm diamond height provides aggressive material removal for fast shaping and beveling.
• Standard 5/8-11 thread and 4-1/2' size make it compatible with most angle grinders and easy to handle for edge work.

Cons

• Coarse 40/50 grit is for roughing and shaping, so separate finer tools are required for polishing or mirror finishes.

Frequently Asked Questions

Can this blade be used on any angle grinder?
Yes, the wheel uses a standard 5/8-11 thread and fits most standard grinders, but always check grinder compatibility and run at recommended speeds.

Is this wheel suitable for wet use?
The product is designed primarily for cutting and grinding; dry use is common for these wheels, while wet use can prolong life for similar diamond tools but check tool and safety guidance.

Will this replace separate cutting and grinding discs?
It can consolidate many rough cutting and shaping tasks thanks to the dual-sided vacuum-brazed diamonds, but it does not replace fine polishing pads for final finishes.
