Industrial Diamond Tools

Technical Comparison of Diamond Segments

Diamond segments are the consumable cutting components sintered or welded onto saw blades, gang saw frames, and core drill bits. The correct segment specification — bond hardness, diamond grit, and segment profile — is determined by the stone's Mohs hardness and abrasiveness, not by the machine brand. The table below compares Dinosaw's four segment types by application parameters.

Notes on specification

Bond hardness is the single most important variable: a soft bond in hard stone exposes fresh diamonds continuously; a hard bond in soft stone retains diamonds until they glaze. Mismatching bond to material is the primary cause of premature segment wear and poor cut quality. Dinosaw supplies segments in custom formulations — contact our technical team with your stone type, blade diameter, and machine RPM to receive a matched specification.

Technical Comparison of Diamond Saw Blades

Diamond saw blades differ from cutting discs in diameter, core thickness, and segment design. Saw blades are typically used on bridge saws, circle saws, and horizontal multi-blade saws where precise depth control and consistent kerf width are required. The table compares Dinosaw's six saw blade products by material and application.

Notes on blade specification

Blade diameter must match the saw guard capacity — never exceed 80% of the guard diameter. Core thickness directly impacts kerf width and therefore material waste: a 3.0mm kerf on 1,000 cuts per day at 2,400mm blade length represents over 7 linear metres of stone lost as dust daily. Thin-kerf blades (2.0–2.5mm kerf) recover this waste but require higher machine rigidity and consistent coolant flow. All Dinosaw saw blades ship with matching segment specifications — do not substitute segments from a different manufacturer without confirming bond compatibility.

Technical Comparison of Diamond Cutting Discs

Cutting discs are angle-grinder and small table-saw format tools (typically 100–230mm diameter) distinguished from larger saw blades by their thinner profiles, lighter machines, and greater portability. The table compares Dinosaw's six disc products by application environment.

Notes on disc selection

The primary decision between disc types is rim profile: segmented rims clear debris aggressively but leave a rougher edge; continuous rims produce clean, chip-free cuts but require wet cooling to prevent heat build-up; turbo rims balance both. For construction site use where wet cooling is impractical, segmented and T-segment discs handle dry cutting. For tile and porcelain in a workshop setting, continuous rim or ultra-thin mesh with water is always the correct choice.

Technical Comparison of Diamond Wire Saws

Diamond wire saws consist of a steel cable strung with diamond beads at regular intervals. They are the primary tool for large-format stone extraction and demolition cutting because they produce an extremely narrow kerf (0.5mm with 0.35mm wire), impose no structural vibration, and can cut unlimited depths and shapes. Wire selection depends on the material, the cutting machine, and whether the goal is dimensional stone production or demolition.

Notes on wire specification

Wire diameter, bead spacing, and bead bond hardness must be matched to the wire saw machine's flywheel diameter and operating speed. Dinosaw supplies wire in custom lengths with matched bead specifications for each machine model. For multi-wire saw machines (Dinosaw and third-party), wire diameter as low as 0.35mm is available for ultra-thin slab production — this is not interchangeable with standard quarry wire. Provide your machine model and target stone type when ordering.

Technical Comparison: Diamond Core Drill Bit Application Matrix

Dinosaw supplies a single core drill bit product line (Stone Dry/Wet Core Bit) covering a wide range of diameters and two drilling modes. Rather than a model-versus-model comparison, the table below maps application scenarios to the correct configuration — bond type, drilling mode, and machine pairing.

Notes on configuration

Core bit lifespan varies significantly by material hardness and cooling adequacy: marble and soft limestone — up to 1,200 linear metres per bit in well-configured factory conditions; hard granite — 200–500 linear metres. These are reference ranges only. Dinosaw offers a re-tipping service: worn core bits can be returned for segment replacement at lower cost than full bit replacement, which is relevant for high-volume factory operations running large-diameter bits.

Technical Comparison of Grinding & Polishing Tools

This category contains tools for four distinct sub-processes in stone surface and edge finishing. The comparisons below are organised by sub-process rather than by product name, because selecting the right tool requires understanding where in the workflow it is used, not just its product label.

Sub-process 1: Surface Grinding & Calibration

Surface grinding is the first stage after cutting — levelling thickness variation, removing saw marks, and preparing the surface for polishing. Tools used in continuous polishing lines or standalone grinding machines.

Sub-process 2: Surface Polishing

Polishing follows grinding and requires a systematic grit progression from coarse to fine. The standard 7-step ladder (50# → 100# → 200# → 400# → 800# → 1500# → 3000# + Buff) is used for mirror finishes on granite and marble. Abridged sequences (3-step, 5-step) are appropriate for softer stone or when pre-finished slabs require only final gloss refinement.

Sub-process 3: Edge Shaping & Profiling

Edge shaping tools create the profiles and cutouts that define the finished product — bullnose, ogee, bevel, waterfall edges on countertops; sink and basin cutouts; floor edge chamfers. These tools run on CNC routers, edge polishing machines, and angle grinders.

Sub-process 4: Engraving & Fine Detail

Engraving tools are used on CNC engraving machines for monument lettering, relief carving, 2D/3D decorative motifs, and custom design work. Bond selection — sintered for granite, brazed for marble — directly impacts line quality and tool life on detailed work.
