Diamond Saw Blade for Dry Cutting — 114 × 1.8 × 20 mm

Diamond saw blades for dry cutting are powerful tools designed to cut through tough, brittle materials like granite, marble, concrete, and cast iron. They are essential for construction, road work, and tile-setting projects. Unlike wet-cutting blades, these are engineered to operate without water, making them ideal for applications where a water source isn't available or dust and slurry need to be managed differently.

Material and application guidance

The original product specification lists granite, marble, concrete, dry-hanging stone and cast iron applications. Actual suitability depends on the blade's diamond formulation, rim design, machine speed, cutting depth and the exact workpiece.

How to select the correct dry-cut diamond blade

1

Confirm the cutting tool

Provide the tool brand, model, spindle or flange arrangement, guard capacity and no-load speed.

2

Identify the workpiece

State the exact material, thickness, reinforcement or inclusions, and whether the cut is straight, curved, slotting or trimming.

3

Define the finish requirement

Tell us whether cutting speed, service life or a cleaner edge is the main priority.

4

Verify speed and direction

The tool speed must not exceed the blade marking, and any directional arrow must match spindle rotation.

Wholesale and OEM inquiry checklist

Include these details for product confirmation and an accurate quotation:

Blade specification

Dry-cutting safety and operating guidance

  • Inspect the blade for cracks, distortion, missing segments or shipping damage before mounting.

  • Use only a compatible guarded tool, correct flange and approved personal protective equipment.

  • Never exceed the maximum operating speed marked on the blade.

  • Follow the directional arrow, keep the blade aligned and do not twist or side-load it in the cut.

  • Use controlled passes and cooling intervals recommended for dry cutting; do not force the blade.

  • Control silica and other hazardous dust with suitable extraction, ventilation and respiratory protection according to local rules.

  • Do not use the blade on a material unless the exact product configuration is approved for that application.

Frequently asked questions

Can this diamond blade be used without water?
Yes. It is specified for dry cutting, but the operator must follow the blade's permitted duty cycle, use controlled passes and allow cooling intervals when required.
Does a 20 mm bore fit every 4.5-inch angle grinder?
No. Arbor and flange systems vary between grinder models and markets. Confirm the tool manual, spindle, flange, guard and blade mounting requirements before use.
What materials can this blade cut?
The current product information lists granite, marble, concrete, dry-hanging stone and cast iron. Because each material requires a suitable rim and diamond formulation, send the exact workpiece details for confirmation before ordering.
Can the blade be used for porcelain or ceramic tile?
Do not assume that a general dry-cut blade will deliver the required tile edge quality. Request a configuration specifically confirmed for the tile type, thickness and desired finish.
Are samples available?
A sample may be supplied for compatibility and cutting tests, with courier freight paid by the customer. Sample availability and shipping cost are confirmed before dispatch.
Can you provide OEM labels and wholesale packing?
OEM options may include blade marking, labels, inner packing, barcodes and carton marks. Send the required quantity, artwork, destination and compliance requirements so MOQ, lead time and pricing can be confirmed.
