Cutting and Grinding Blade

Product Overview

The GUSHI Cutting and Grinding Blade is a hot-pressed sintered 2-in-1 diamond tool that cuts tile and stone and grinds the edge to a finished surface in a single pass. It eliminates the classic two-tool workflow — a cutting disc followed by a separate grinding cup wheel — so tile setters, stone fabricators and countertop shops finish 45° bevels, miters and bullnose edges without switching tools. Available in 4.5" (115mm), 5" (125mm), 7" (180mm) and 9" (230mm) with 16/20/22.23mm arbors, the HEP series is manufactured by Huzhou Gu's Imp. & Exp. Co., Ltd. (founded 2004, ISO 9001:2015, CE and EN13236 certified) and exported to 20+ countries with an OEM MOQ of 500 pieces.

The innovation is the segment geometry. The X-turbo and hive (honeycomb) diamond layers cut fast and stay cool through deep kerf clearance, while the wide diamond-coated side layer grinds the cut face as the blade passes. On a 45° bevel cut, the rim slices the tile at angle and the side layer simultaneously dresses the bevel smooth — producing a seam-ready edge in one operation instead of two.

The HEP series is built on the same 65Mn spring steel core platform as the rest of the GUSHI diamond blade range — laser stress-relieved, computer-balanced to 0.1mm runout, and certified to EN13236 burst-speed standards. Operators run it at up to 12,200 RPM on a standard angle grinder with the confidence of a blade that runs true from the first cut to the last.

For distributors, the cutting and grinding blade is a fast-moving SKU with a clear sales story: it saves labor, reduces tool inventory and delivers a better finished edge on visible miter work. GUSHI supports it with OEM branding, custom packaging and segment bonds tuned to your local tile and stone market.

How the Cutting & Grinding Blade Works

1. Two Diamond Functions on One Steel Core

The blade combines a cutting rim with a grinding side layer. The rim — X-turbo or hive pattern — is built from hot-pressed sintered diamond segments that slice through porcelain, granite and marble. The sides of the segments carry a wide diamond coating (up to 25mm of active surface) that abrades the cut face as the blade rotates, dressing the edge to a smooth, finished profile.

2. Bevel and Miter Cutting Without a Second Tool

On a 45° bevel cut, the operator tilts the grinder to the required angle and makes the cut in the normal way. The rim cuts the tile; the diamond side layer simultaneously grinds the bevel surface, removing the saw marks and micro-chips that a plain cutting blade would leave behind. The result is a seam-ready miter edge with no separate grinding pass.

3. X-Turbo / Hive Geometry Balances Speed and Finish

The X-turbo segments present a continuous serrated edge that cuts aggressively yet controllably, while the hive (honeycomb) diamond pattern adds cutting surface area for a smoother finish on glazed porcelain. Both geometries clear debris through the gullets, keeping the segment edge cool during dry cutting on interior job sites.

Key Features Explained

True 2-in-1: Cut and Grind in One Pass

The blade's defining feature is that it eliminates a whole step from the workflow. Instead of cutting with a disc, swapping to a cup wheel and grinding the edge, the operator completes both operations with one blade. On a typical kitchen countertop job with 20+ beveled miters, this can cut finishing time by roughly 30-40%.

Wide Double-Sided Diamond Edge Layer

The segments carry a 25mm-wide diamond side layer on both faces. This is what turns a cutting disc into a grinding tool: as the blade passes through the kerf, the side layer dresses the vertical cut face — removing saw marks, easing sharp edges and producing the clean, slightly radiused finish that specifiers expect on visible miter joints and bullnose edges.

Hot-Pressed Sintered Segments

Segments are compressed and sintered at high temperature in a cobalt-nickel matrix, giving 8-10× the life of an abrasive disc and reliable performance on hard porcelain and granite. The matrix is tuned so the blade stays sharp through its 10mm segment height without glazing.

65Mn Spring Steel Core, Balanced to 0.1mm

The core is laser stress-relieved and computer-balanced to a 0.1mm runout tolerance, so the blade runs smoothly at 12,200 RPM. Low vibration means cleaner bevels, less chipping on glazed tile and no premature wear on the grinder spindle.

EN13236 Safety Compliance

Manufactured and tested to EN13236, with max RPM marked on every core and SGS inspection reports available per batch. For importers, this is the documentation your compliance team needs before the container clears customs.

Blade Size Selection Guide

Choose the diameter by machine and job type. All sizes use the standard 22.23mm angle-grinder arbor; 16mm and 20mm bushings are included.

2-in-1 Blade vs. Abrasive Disc + Separate Grinding

The traditional method for cutting tile and finishing edges uses an abrasive cutting disc plus a separate grinding cup wheel — two tools, two purchases, two changes. Here is how the GUSHI cutting and grinding blade compares on a typical tiling or countertop job:

Bottom line: If you cut tile or stone for a living, the 2-in-1 blade removes a step from every job and replaces a box of abrasive discs — the labor saving alone typically pays for the blade within the first project.

How to Use: Step-by-Step Guide

1. Inspect the blade for cracks, missing segments or worn side layers — never mount a damaged blade.
2. Confirm the blade's marked max RPM is equal to or higher than your grinder's no-load speed.
3. Clean the arbor and flanges; mount the blade with the logo facing out, matching the rotation direction.
4. Tighten the spindle nut to the manufacturer's torque spec with the wrench — never hand-tighten.
5. Run a 60-second test at full speed clear of the workpiece; listen for vibration or wobble.
6. For straight cuts, mark a guide line, let the blade reach full speed, then feed gently into the tile.
7. Use a back-and-forth sawing motion in the kerf to clear debris and keep the segment cool.
8. For a 45° bevel, tilt the grinder to the required angle and make the cut in one steady pass — the side layer grinds the bevel as you go.
9. For bullnose edges, run the blade along the edge at a shallow angle with light side pressure to dress it smooth.
10. On granite and quartz, cut wet and reduce feed pressure; never force the blade or twist it in the kerf.
11. Stop immediately if you see blue discoloration or smell burning — the bond is wrong for the material or the feed is too aggressive.
12. After use, spin down fully, inspect segments and side layers, and store the blade flat in a dry place.
