230mm Dekton Turbo Diamond Saw Blade

Product Overview — 230mm Dekton Blade

The GUSHI 9THPST 230mm (9 inch) Turbo Diamond Blade is the full-size member of the THPST series — a hot-pressed sintered blade with an ultra-thin continuous-rim turbo design engineered specifically for ultra-compact sintered surfaces: Dekton, Lapitec and Neolith. The 1.6mm narrow kerf cuts fast and clean with almost no chipping, and an advanced steel core reduces noise during cutting. Rated to 6,800 RPM max with a 22.23/25.4mm arbor for 9 inch angle grinders and hand-held saws, it is manufactured by Huzhou Gu's Imp. & Exp. Co., Ltd. (founded 2004, ISO 9001:2015, CE and EN13236 certified) with an OEM MOQ of 500 pieces.

The 230mm size is the workhorse for full-thickness slab work. Where smaller 4–7 inch turbo blades serve trim and detail, the 9 inch blade covers the deepest, straightest arc per pass — making long Dekton and Neolith miter and seam cuts smoother and reducing the number of passes on a full slab. The defining feature is still the super-thin turbo rim tuned to the density of sintered stone: narrowed to 1.6mm and given a turbo profile that clears slurry, it glides through full-thickness slabs with far less chipping than a typical turbo blade on the market.

The blade is built on the same 65Mn spring steel core platform as the rest of the GUSHI range — laser stress-relieved, computer-balanced and EN13236 burst-speed tested. The "advanced core" is a reinforced, noise-reducing core that dampens the high-pitched whine of high-speed rotation, which matters most during the long, full-thickness cuts that Dekton and Neolith fabrication demands. On most cuts, the edge is already clean enough that no edge-grinding pass is needed.

For distributors serving the premium countertop and sintered-surface market, the 9THPST is a clear, high-intent SKU: the 230mm size is exactly what fabricators search for when they need to cut Dekton slabs on a 9 inch grinder. GUSHI supports it with OEM branding, custom packaging and segment bonds tuned to local sintered-stone and porcelain markets. The same THPST line is also available in 4"–8" sizes — see the full Dekton Turbo Blade range for the complete 100–230mm set.

230mm (9THPST) Specifications

How the 230mm Turbo Blade Works

1. Ultra-Thin 1.6mm Turbo Rim Cuts Clean Through Full-Thickness Slabs

At 230mm, the 9THPST rim is narrowed to just 1.6mm and given a continuous turbo profile. Because the kerf is so thin, the blade removes less material per pass and generates less side pressure on the slab — which is exactly why Dekton, Neolith and Lapitec chip less. The turbo profile adds cutting edge and clears slurry, keeping the cut cool and smooth on a full-thickness slab rather than bogging down like a blunt thick blade.

2. Hot-Pressed Sintered Segments Hold a Sharp Edge on Hard Surfaces

Segments are compressed and sintered at high temperature in a cobalt-nickel matrix, locking in high-quality industrial diamond grit. The bond is tuned so the blade stays sharp across the full 5–10mm segment height without glazing, delivering long, stable cutting performance on the densest engineered surfaces — and more cuts per blade on premium Dekton stock.

3. Advanced Core Reduces Noise at 6,800 RPM

The 65Mn core is laser stress-relieved and computer-balanced to a 0.1mm runout tolerance, so the 230mm blade runs true at its 6,800 RPM rating and produces straight, precise cuts. The advanced, reinforced core additionally dampens the whine of high-speed rotation — a practical advantage during the long, full-thickness cuts that sintered-stone fabrication demands on a 9 inch grinder.

Key Features Explained

The 230mm Size Is the Slab Workhorse

The 9 inch / 230mm diameter is the standard for full-thickness Dekton, Neolith and Lapitec work on a 9" angle grinder or hand-held cut-off saw. It covers a longer arc per pass than smaller blades, making long miter and seam cuts smoother and reducing passes on a full slab. Smaller 4–7 inch THPST sizes remain the choice for trim and detail.

Super-Thin 1.6mm Kerf — Almost No Chipping on the Hardest Surfaces

The 1.6mm kerf is the core benefit for sintered stone. A thinner cut means less material torn from the slab (fewer chips), less stone discarded per cut, and lower resistance on the grinder — which reduces motor load and extends tool life. On full-thickness Dekton and Neolith, the narrower cut consistently delivers a cleaner edge than a typical turbo blade on the market.

Selectable 5–10mm Segment Height

Operators choose segment height by job: thinner 5–7mm segments for fine trim work, thicker 8–10mm for longer life on full-thickness slabs. More diamond height means more cuts before the blade is spent — a direct lever on cost per cut on premium material, and especially valuable at the 230mm size where each blade sees heavy slab use.

Dry or Wet — Works Where You Need It

The blade is rated for dry cutting (convenient on site and interior trim) and wet cutting (recommended for Dekton, Neolith and Lapitec to keep the thin rim cool, suppress dust and extend segment life). A light water spray is enough to extend segment life on a hard slab without a full wet table.

Advanced Noise-Reducing Core

The advanced core dampens vibration and the characteristic blade whine, improving operator comfort during long slab-cutting sessions on a 9 inch grinder and meeting expectations on residential and retail jobs. It is the standard core on the THPST series.

Size Selection Guide (THPST Series)

The 230mm / 9THPST is highlighted below. Choose the diameter by machine and material. Max RPM figures are reference values (GUSHI/Roycel published data for 115/125/230mm plus ~80 m/s peripheral-speed calculation for the others); always verify against the RPM marked on your specific blade and the machine's no-load speed.

9THPST 230mm Blade vs. Standard Turbo Blade

A standard turbo blade is a generalist for tile and masonry; the 9THPST is engineered as a sintered-stone specialist in the 230mm size. Here is how they compare for Dekton, Neolith and Lapitec work on a 9 inch grinder:
