Nueva hoja de sierra de diamante de diseño innovador

Product Overview

The GUSHI XLD New Design Turbo Diamond Saw Blade is a general-purpose construction and stone blade whose turbo rim is fitted with circular protective segments. These protective segments shield the steel core from undercutting and side wear, so the blade holds its true diameter and running shape far longer than a standard turbo blade. The XLD series spans 10 diameters from 4″ (105mm) to 14″ (350mm) with 8mm segment height and 20/22.23/25.4mm arbors, cold-pressed for fast cutting of granite, marble, concrete, brick and masonry. It is manufactured by Huzhou Gu’s Imp. & Exp. Co., Ltd. (founded 2004, ISO 9001:2015, CE / MPA / EN13236 certified) with an OEM MOQ of 500 pieces.

The defining feature is the new-design rim. On a conventional turbo blade the core is exposed between the cutting segments; as the blade cuts abrasive material, the core gradually wears away (undercutting) until it becomes too thin and the blade must be retired. The XLD adds circular protective segments — wear bars that sit proud of the core and take that abrasion instead. The cutting segments do the work; the protective segments preserve the blade.

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. Where the thin HHPST and THPST turbo blades are tuned for chip-free cutting of fragile tile, porcelain and sintered stone, the XLD is the heavier workhorse for tough building materials where blade longevity and core protection matter more than a hairline-clean edge.

For distributors, the XLD is a high-volume staple SKU: a broad 4″–14″ range covering grinders through masonry saws, a clear durability story (more cuts per blade), and OEM support with branded packaging. GUSHI backs it with the same anti-dumping-case pedigree and 20+ country export record as the rest of the line.

How the Protective-Segment Design Works

1. Circular Protective Segments Guard the Core

Between the cutting segments sit circular protective (gear/guard) segments that stand proud of the steel core. As the blade spins through abrasive concrete or stone, these protective segments take the sideways wear that would otherwise eat into the core. The core stays full thickness, so the blade keeps cutting true instead of wandering as the centre thins.

2. Turbo Rim Cuts Fast Through Hard, Abrasive Material

The turbo profile adds cutting edge and clears slurry and dust through the cut, so the blade advances fast in granite, concrete and brick without bogging down. The 8mm segment height gives a long service window before the diamond is spent.

3. Balanced Steel Core for Stability on Deep Cuts

The 65Mn core is laser stress-relieved and computer-balanced to a 0.1mm runout tolerance. Combined with the protective segments, the blade runs stable even on the deep, demanding cuts that normally flex and destroy a standard core — a key reason it lasts longer on the job.

Key Features Explained

Protective Segments = More Cuts Per Blade

Undercutting is the silent killer of ordinary turbo blades. The XLD’s protective segments absorb that wear, so the blade holds its diameter and structural integrity for far longer. On abrasive jobs (concrete, block, brick) this translates directly into fewer blade changes and lower cost per cut.

General-Purpose Range, 4″ to 14″

Ten diameters cover everything from an angle grinder on a 4″ blade to a 14″ masonry saw. One product family serves tile shops, stone fabricators and construction sites, simplifying inventory and ordering for distributors.

8mm Segment Height for Long Life

The 8mm segment height gives a generous diamond window. More diamond height means more cuts before the blade is spent — a direct lever on cost per cut in high-volume stone and concrete work.

Dry or Wet — Works Where You Need It

The blade is rated for dry cutting (ideal on site and for masonry without water) and wet cutting (recommended for granite, marble and long concrete cuts to keep segments cool and control dust). A light water spray is enough to extend segment life without a full wet table.

Certified, Trade-Case Backed Manufacturer

GUSHI is ISO 9001:2015 certified with CE, MPA, EN13236 and SGS references, and ships under a competitive 6.2% U.S. anti-dumping duty rate from its successful trade-case defense. Distributors get a credible, compliant supply story.

Size Selection Guide (XLD Series)

Choose the diameter by machine and material. Max RPM figures are reference values (~80 m/s peripheral-speed calculation, the standard basis for diamond-blade ratings); always verify against the RPM marked on your specific blade and the machine’s no-load speed.

Applications & Suitable Materials

New-Design XLD vs. Standard Turbo Blade

A standard turbo blade works, but its exposed core wears away on abrasive jobs. The XLD new-design blade adds protective segments to solve exactly that. Here is the comparison:

Bottom line: On abrasive jobs the XLD pays back through more cuts per blade and fewer core failures — the savings come from durability, not just the sticker price. For chip-free tile and porcelain, pair it with the HHPST / THPST thin turbo blades instead.

How to Use: Step-by-Step Guide

1. Inspect the blade for cracks, missing segments or damaged protective segments — never mount a damaged blade.
2. Confirm the blade’s marked max RPM is equal to or higher than your grinder, circular or masonry saw’s no-load speed.
3. Clean the arbor and flanges; mount the blade with the correct bushing and rotation direction (logo facing out).
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. Mark a guide line; let the blade reach full speed, then feed gently into the material — do not force it.
7. Use a steady push; the turbo rim cuts best with consistent pressure, not heavy force.
8. For granite, marble or long concrete cuts, use a wet saw or light water spray and keep the rim cool.
9. On brick, block and masonry, dry cutting is fine — but wear a respirator for silica dust.
10. Stop immediately if you see blue discoloration or smell burning — the bond is wrong or the feed is too aggressive.
11. Never twist the blade in the kerf or side-load it; keep the cut square to the material.
12. After use, spin down fully, inspect segments and protective bars, and store the blade flat in a dry place.
