How to Choose Diamond Segments

Segment selection follows a simple material-first logic. The process below applies whether you are specifying segments for a new blade order or re-tipping an existing blade.

Step 1 — Identify your stone's Mohs hardness

• Mohs 6–7 (granite, quartzite, dark basalt, sandstone): these are hard, low-abrasion materials. They do not expose diamonds quickly, so the segment bond must be soft enough to wear and release worn diamonds on its own. Use the Granite Segment.
• Mohs 3–5 (marble, limestone, travertine, onyx, soft sandstone): these are soft, often highly abrasive materials. They wear bond quickly, so the segment must hold diamonds for longer. Use the Marble Segment or Gangsaw Segment.
• Mixed or uncertain: if you process both hard and soft stone on the same blade, specify a medium-bond segment and contact Dinosaw's team for a mixed-material formulation.

Step 2 — Match segment to machine and application

• Circle saw / bridge saw slab cutting: use the Granite Segment (hard stone) or Marble Segment (soft stone) in standard saw blade format.
• Frame gang saw (multi-blade block-to-slab): use the Gangsaw Segment — it is engineered for the reciprocating motion and the higher lateral loads of gang saw frames.
• Core drill bit (countertop holes, quarry guide holes, construction drilling): use the Core Drill Bit Segment, which is sized and profiled for cylindrical bore cutting rather than lateral saw cutting.

Step 3 — Specify wet or dry cutting

• Wet cutting (water cooling at blade): required for granite, marble, and all hard stone in production settings. Extends segment life significantly and prevents thermal cracking in the stone.
• Dry cutting: only acceptable for occasional shallow cuts in softer materials (concrete, brick) using angle grinders. Never use dry segments on production circle saws or gang saws.

Step 4 — Quantity and supply format

Dinosaw supplies segments in four formats: laser-welded blade assembly (segments already on blade), loose segments for field re-tipping, bulk packs for factory consumable programmes, and custom-specification batches for OEM blade manufacturers. Minimum order quantities and lead times vary by format — request a quote with your annual segment consumption volume for programme pricing.

How to Choose a Diamond Saw Blade

The correct blade is determined by three factors in order: the material being cut, the machine being used, and the required cut quality. Getting the first factor wrong invalidates the other two.

Step 1 — Material hardness and composition

• Natural granite (Mohs 6–7): Diamond Saw Blade for Granite. Laser-welded sintered segments with segmented rim for debris clearance. Wet cutting mandatory at production feed rates.
• Natural marble, limestone, travertine (Mohs 3–4): Diamond Saw Blade for Marble. Softer bond matrix with continuous or fine segment — marble's softness and abrasiveness require a bond that wears steadily rather than glazing.
• Engineered quartz (Mohs 6–7 with resin binder): Quartz Diamond Saw Blade (thin-kerf). The resin component in quartz causes gumming on standard granite blades. The thin-kerf chip-control design maintains a cooler cut and prevents resin build-up on segments.
• Sintered ceramic, Dekton, Neolith, Lapitec (Mohs 7–9): Diamond Saw Blade for Dekton & Sintered Stone. These ultra-hard materials require vacuum-brazed or thin-kerf sintered segments with mandatory high-flow wet cutting (≥8 L/min). Do not use a granite blade on sintered stone — segment failure will occur rapidly.
• Full-body porcelain, rectified ceramic tile (Mohs 7–8): Sintered Diamond Saw Blade for Ceramic & Porcelain. Engineered for clean edge on brittle, highly-fired materials.
• Horizontal slab cutting, block squaring: Horizontal Diamond Saw Blade. Large-diameter format for multi-blade horizontal saws; laser-welded for the lateral loads specific to horizontal cutting.

Step 2 — Machine compatibility

Bridge saws, circle saws, and CNC table saws require different core diameters and arbor configurations. Confirm your machine's spindle bore, maximum blade diameter, and motor power before ordering. Dinosaw's technical team can cross-reference your machine model against the correct blade specification — this service is available at no cost with any sample or production enquiry.

Step 3 — Wet vs. dry and feed rate

• All natural stone cutting at production feed rates: wet cutting required. Minimum water flow at the blade face should maintain a continuous film — not splash. For bridge saws: 8–15 L/min depending on blade diameter.
• Sintered ceramic and Dekton: wet cutting is not optional. Dry cutting on these materials will destroy segments and risk blade body separation.
• Tile and occasional construction cuts: some disc blades (not full saw blades) permit short dry runs. See Cutting Disc category.

How to Choose a Diamond Cutting Disc

Step 1 — Application environment: site or workshop

• Construction site, dry cutting, general masonry: Segmented Cutting Disc for Concrete & Masonry or T-Type Segmented Disc. Segmented rims cool themselves through debris ejection and tolerate dry cutting for short runs.
• Workshop tile and stone cutting, wet table saw: Continuous Rim for glazed tile and ceramic; Ultra-Thin Turbo Mesh for full-body porcelain; Turbo Continuous for granite and hard stone tiles.
• Confined cuts, rapid stock removal on hard stone: Bevel Turbo Segmented — the bevel design assists debris exit in tight geometries.

Step 2 — Edge quality requirement

• Clean, chip-free edge (wall tile, polished porcelain, display stonework): continuous rim or ultra-thin mesh. Always use wet.
• Rough cut for further finishing: segmented rim — faster cut, coarser edge.
• Balanced speed and finish (general-purpose hard stone): turbo continuous rim.

Step 3 — Angle grinder compatibility

Confirm your grinder's maximum disc diameter (100mm, 115mm, 125mm, 230mm are standard), spindle speed (RPM), and whether wet attachment is available. All Dinosaw cutting discs conform to EN 13236 safety ratings. Maximum operating speed is marked on every disc — never exceed this, and always verify the disc RPM rating exceeds your grinder's no-load speed.

How to Choose a Diamond Wire Saw

Step 1 — Quarry/fabrication vs. demolition/construction

• Stone quarry block extraction and squaring: Diamond Wire Saw for Granite or for Marble, depending on stone type. Optimised for low kerf loss and high surface quality on dimensional stone.
• Concrete cutting, demolition, infrastructure removal: Diamond Wire for Reinforced Concrete Cutting. This wire is engineered to handle rebar without bead stripping and is used for bridge cutting, nuclear decommissioning, dam repairs, and slab removal where explosives are not permitted.
• Precision curved and contoured cuts, shaped stone products: Electroplated & Vacuum Brazed Diamond Wire Saw — suited for small-radius turns and detailed cutting where standard sintered wire cannot flex tightly enough.

Step 2 — Material: marble vs. granite

• Marble (Mohs 3–4): the Diamond Wire Saw for Marble uses a soft sintered bond with fine diamond distribution that matches marble's lower abrasiveness. Using a granite wire on marble over-cuts and increases waste.
• Granite and hard stone (Mohs 6–7): the Diamond Wire Saw for Granite uses a hard sintered bond with high diamond concentration to sustain penetration through abrasive formations without bead glazing.

Step 3 — Integration with DTH drilling (quarry workflow)

In quarry extraction, DTH drill rigs create the entry and exit holes for the wire. The QKZ90 series DTH drill (Φ65–90mm holes) is specifically dimensioned to match Dinosaw's quarry wire saw gauge. This means the entire workflow — drill holes, thread wire, run wire saw machine — uses a single integrated system from one supplier, eliminating dimensional incompatibilities between the hole and the wire. This is a logistics and quality advantage that single-product suppliers cannot offer.

How to Choose a Diamond Core Drill Bit

Step 1 — Wet or dry drilling mode

• Wet drilling (water-cooled through hollow spindle): superior for all hard, thick materials. Extends bit life by a factor of 3–5× vs dry, flushes cuttings continuously, and produces a cleaner hole wall. Required for granite, reinforced concrete, and any material thicker than 30mm.
• Dry drilling: only for thin, soft materials (glazed ceramic tile, shallow holes in marble) where water is impractical. Do not dry-drill granite at production depth — the bit will overheat, segments will detach, and the hole quality will be unacceptable.

Step 2 — Bond hardness to stone hardness

• Hard stone (granite, quartzite, Mohs 6–7): soft bond matrix. The stone's hardness does not naturally wear the bond away, so the bond must be soft enough to self-expose fresh diamonds. A hard bond bit on hard granite glazes within the first few holes.
• Soft and medium stone (marble, limestone, engineered stone, Mohs 3–6): hard bond matrix. These materials wear the bond quickly, so the bond must hold diamonds longer to maintain cutting efficiency.
• Glazing symptom: bit rotates but does not advance, surface appears polished — this means the diamonds are buried. Dress the bit by running it through a silicon carbide block, or switch to a softer bond specification.

Step 3 — Machine and diameter selection

Core bit diameter must match the required hole size, not the machine capacity. Common reference diameters: standard faucet hole 35mm; kitchen sink cutout start 60mm; countertop core samples 50–100mm; DTH quarry guide holes 65–90mm; architectural columns up to 600mm (gantry drilling machine required). For diameters above 150mm, a bench-mounted or gantry drilling machine is required — handheld drills do not provide the stability or torque required at these diameters.

How to Choose Diamond Grinding & Polishing Tools

Tool selection in this category is determined by your position in the processing sequence, your stone type, and your machine setup. The quick selection guide below maps common tasks to the correct tool. Detailed selection logic by sub-process follows.

Step 1 — Define your position in the processing sequence

• Raw slab from cutting, saw marks visible, thickness variation: start with grinding (Fickert / Frankfurt / Cup Wheel at coarse grit). Do not start with polishing pads — they are designed to remove the previous step's scratches, not raw saw marks.
• Slab pre-ground to flat surface, no major defects: start with medium resin Fickert (200–400 grit) to bridge from grinding to polishing, then continue through the polishing pad ladder.
• Factory-polished slab with minor site damage or installation scratches: start polishing pad sequence at 400# or 800# depending on scratch depth. A 50# pad on a near-polished surface will over-grind and extend restoration time significantly.

Step 2 — Match bond type to stone hardness

• Granite, quartzite, basalt (Mohs 6–7): metal bond Fickert and Frankfurt for grinding stages; resin bond pads for polishing. Sintered router bits and profiling wheels for edge work.
• Marble, limestone, travertine (Mohs 3–4): resin bond Frankfurt and resin Fickert for intermediate stages; resin bond pads (wet preferred) for polishing. Vacuum-brazed router bits for profiling — marble's softness benefits from the higher diamond exposure of brazed tools.
• Engineered quartz (Mohs 6–7 with resin): treat as granite for grinding; use wet polishing with higher flow rate than natural stone to prevent pad loading from the resin binder.

Step 3 — Machine compatibility

Most Dinosaw grinding and polishing tools are designed with Velcro (hook-and-loop) backing or standard M14 thread mounting. For continuous polishing line machines (Fickert / Frankfurt format), confirm the machine's head count and segment holder dimensions. For CNC router and engraving tools, confirm spindle taper, shank diameter (typically 6mm or 8mm for carving bits), and maximum RPM. Dinosaw's tooling is tested on Dinosaw grinding and polishing machines and is compatible with all major third-party brands — if in doubt, request a compatibility checklist with your machine make and model.
