230mm T-Segment Diamond Blade for Granite — Granite Professional

The Vus Cutting Technology 230mm Granite Professional T-segment diamond blade is a hand-held angle grinder blade designed specifically for production granite work. At 230mm it delivers the cutting depth needed to work through full-thickness granite slabs, tombstone panels, and countertop material in a single pass — making it the go-to blade for stonemasons, tombstone manufacturers, and countertop fabricators who need reliable, fast granite cutting from a large-disc grinder.

The T-segment design sets this blade apart from standard segmented granite blades. Where a conventional segment has straight sides and a flat cutting face, the T-segment features a wider cutting face supported by a narrower body. This T-profile does two things: it increases the diamond-bearing surface area at the top of each segment, putting more cutting material in contact with the stone on each rotation, and it deepens the effective gullet space between segments, improving cooling water flow and stone slurry clearance during wet cutting.

The result is a blade that cuts faster than standard segment designs on the same material, runs cooler, and maintains a cleaner cutting face with less slurry build-up — translating to more cuts per blade and lower cost-per-metre in a production granite workshop environment.

Best For

• Granite slab sizing and through-cuts in tombstone manufacturing workshops
• Countertop slab work on granite, quartzite, and similar hard natural stone
• Production workshop cutting where speed and blade life are the priority
• Hand-held angle grinder work on thick granite panels and slabs
• Stonemasons working on site or in smaller workshops without a bridge saw
• Rough profiling and shaping of granite before edge finishing
• Any application requiring fast, deep wet cutting of hard granite on a 230mm angle grinder

The T-Segment Advantage on Granite

Granite is one of the most abrasive natural stones encountered in fabrication work. It generates significant heat at the blade-stone interface during cutting and produces a fine, highly abrasive dust that accelerates segment wear if not flushed away effectively. Standard straight segments perform adequately on granite, but the T-segment profile addresses both of these challenges more effectively:

• More cutting surface: The wider T-face puts a larger diamond-bearing area in contact with the stone on each rotation. This spreads the cutting load across more diamond, reducing the wear rate on any individual point and maintaining a sharper, more aggressive cutting face for longer.
• Better cooling: The deeper effective gullet between T-segments allows more water to reach the cutting zone directly, improving blade cooling and preventing the thermal build-up that causes premature diamond glazing on hard granite.
• Cleaner cutting face: The improved water flow and wider gullet cross-section flush stone slurry out of the cut more effectively, preventing the slurry from being re-cut on each rotation — a common cause of blade drag and reduced cutting speed on hard stone.

For tombstone manufacturers and countertop fabricators who are cutting granite daily, the T-segment design delivers a measurable improvement in both cutting speed and blade longevity compared to standard segment alternatives at a similar price point.

T-Segment vs Continuous Rim — Choosing the Right Blade for the Job

Both blade types are available in 115mm for angle grinder use, but only the T-segment is available in 230mm. For most 230mm granite work, the T-segment is the correct choice because:

• At 230mm, cutting speed and depth are the primary requirements — the T-segment delivers both.
• The cut face produced by the T-segment blade is clean and consistent for most granite fabrication purposes, including tombstone panels that will be further finished by sandblasting or polishing.
• For final edge finishing on polished surfaces where absolute chip-free edge quality is required, switch to the 115mm continuous rim blade for the finishing pass. This two-blade workflow — 230mm T-segment for the main cut, 115mm continuous rim for the edge finish — is standard practice in quality tombstone and countertop workshops.

Technical Specifications

Machine Compatibility

This blade fits any large-disc angle grinder with a 22.23mm arbour — the standard spindle size on all 230mm / 9-inch angle grinders. Compatible with popular brands including Makita, DeWalt, Bosch, Metabo, and Ryobi large-disc grinders commonly used in South African stone fabrication workshops and on site.

Always confirm your grinder’s maximum disc diameter and rated RPM before fitting. Never fit a 230mm blade to a grinder rated for a smaller disc diameter.

Safety & PPE

Granite work with a 230mm angle grinder generates high-velocity stone particles, silica dust, and significant noise. Always observe the following:

• Connect water supply and confirm flow before beginning any cut — do not use this blade dry
• Wear a full face shield and safety glasses at all times
• Wear an N95 or higher-rated dust mask — granite dust contains crystalline silica, a serious respiratory hazard
• Wear hearing protection during extended use
• Wear cut-resistant gloves when handling stone and blades
• Inspect the blade before every use for cracks, missing segments, or damage to the steel core
• Ensure the blade guard is correctly fitted to your angle grinder before use
• Maintain a firm two-handed grip on the grinder throughout the cut
