Wheel Safety
Cutting wheels operate at high rotational speeds. Poorly manufactured or damaged wheels can create serious hazards. Correct wheel selection, machine compatibility, operating speed and safe handling are essential.

A Better Cutting Disc Starts with the Right Abrasive System
Metal cutting looks simple from the outside: install a disc on an angle grinder, start the machine and cut the workpiece. In a production environment, however, the cutting wheel becomes part of a much larger process. Cutting speed, wheel wear, heat generation, operator control, edge condition, changeover frequency and machine compatibility can all affect the actual cost of every cut.
This is why choosing a metal cut off wheel should not be based only on the lowest price per piece. A suitable cutting disc for grinder applications must be matched to the wheel diameter, thickness, operating speed, workpiece material and cutting conditions.
FUJI Grinding Wheel provides resin-bonded abrasive solutions for these requirements, from compact 4-inch cutting discs for general fabrication to heavy-duty cut-off wheels for shipyards, steel structures and foundry work.
For Southeast Asian industrial users:
The product range is designed around common handheld grinder and industrial cutting applications, with particular attention to practical productivity, wheel stability and total consumable cost.

Why Cheap Metal Cutting Discs Can Become an Expensive Production Problem
Procurement teams often compare abrasive products by unit price. Workshop supervisors see the problem differently: how many cuts can be completed, how often the operator must change wheels, how much rework is required, and whether performance remains consistent from one batch to the next.
Batch Consistency
A wheel that cuts quickly in one batch but wears rapidly in the next creates unpredictable production costs. Industrial buyers need repeatable manufacturing parameters and quality control.
Heat & Rework
Stainless steel and other difficult materials can generate significant heat during dry cutting. Excessive heat may contribute to discoloration, burr formation and additional finishing work.
Industrial safety reminder:
Never use a cutting wheel that is cracked, damaged, improperly mounted or rated below the grinder's operating speed. Always follow the wheel marking, grinder manufacturer's instructions and applicable workplace safety requirements.

Indicative B2B pricing for the featured cutting wheel program is approximately US$1.50–US$6.50 per piece, depending on model, specification, packaging, order volume and application. Confirm the final quotation before purchase.
1. Super Tsurugi — 4" and 4.5" Thin Cutting Discs
The Super Tsurugi series is designed for users who need an economical and practical grinder cutting disc for everyday metal fabrication. The 105 × 1.0 mm version is particularly relevant to Southeast Asian markets where compact handheld angle grinders are widely used.
When cutting large steel sections, the wheel is subjected to considerably greater mechanical and thermal demands. The Raicho Gold 180 × 2.6 mm is designed for heavy industrial applications where durability, stability and fewer wheel changes are important.
Typical applications include steel structure fabrication, shipbuilding, marine equipment, foundries, casting sprue and riser cutting, and thick-wall pipe.
Its reinforced structure is designed to improve resistance to lateral twisting and impact during demanding cutting operations. Internal application testing supplied in the product materials indicates that the wheel can provide a substantial productivity improvement in suitable heavy-section applications. Actual results depend on material, operator technique, machine power and cutting conditions.
See the Raicho heavy-duty cutting wheel for detailed product information.
3. Hakusan — 12" to 18" Stationary Cutting Wheels
Handheld angle grinders are not suitable for every cutting operation. Large production workshops often use stationary dry cutoff machines for pipes, profiles, bars and other repeatable cutting work.
The Hakusan series covers 305, 355, 405 and 455 mm diameters with 2.8 or 3.0 mm thickness options. Selected formulations use WA36N white aluminum oxide abrasive grain for controlled cutting of metal sections, including stainless steel applications.
For production teams concerned about heat, discoloration and secondary finishing, choosing the correct abrasive formulation and machine parameters can help reduce unnecessary rework.

Manufacturing & Quality
What Is Inside a Resin-Bonded Cutting Wheel?
A professional cutting disc is not simply abrasive powder pressed into a circle. Its performance depends on the interaction between abrasive grain, resin bond, reinforcing fiberglass, wheel density, curing conditions and dimensional accuracy.
Abrasive Grain
Determines cutting behavior and interaction with the workpiece.
Resin Bond
Holds abrasive particles together and controls wheel strength and wear behavior.
Fiberglass Reinforcement
Supports the wheel structure during high-speed rotational operation.
Controlled Curing
Manufacturing conditions influence density, bond strength and consistency.
Hot-Press Manufacturing
FUJI uses mature hot-press manufacturing technology for selected resin-bonded abrasive products. Controlled heat and pressure during curing can help create a dense and uniform abrasive structure with stable bonding characteristics.
This manufacturing approach is one reason abrasive wheel production should be evaluated as a complete process, rather than by looking only at abrasive grain type or wheel thickness.
Technical reference:

How to interpret field-test results:
Cutting speed and wheel life are influenced by material grade, thickness, machine power, spindle speed, operator technique, cutting pressure and environmental conditions. Field videos should be treated as application evidence rather than a universal guarantee of performance.
Technical Selection
Match the Cutting Disc to the Angle Grinder
One of the most important safety principles for any abrasive cut-off wheel is correct speed matching. The maximum operating speed marked on the wheel must never be exceeded.
Diameter alone is not enough. Buyers should verify the wheel's maximum RPM, peripheral speed, grinder rating, bore size, wheel condition and application before use.
Practical RPM Selection Checklist
| Check | What to Verify |
|---|---|
| Wheel Diameter | Confirm the grinder accepts the selected wheel diameter. |
| Maximum RPM | Grinder operating speed must not exceed the wheel's marked maximum speed. |
| Wheel Type | Use a cutting wheel for cutting. Do not use a flat cut off wheel for side grinding. |
| Material | Select the appropriate formulation for carbon steel, stainless steel or the intended workpiece. |
| Condition | Do not use wheels that are cracked, damaged, wet or improperly stored. |
Use our grinding wheel speed and RPM conversion guide for a more detailed wheel-speed reference.
