FUJI resin cutting discs support everyday construction metalwork, from cutting steel rebar to trimming steel door frames, window sections, tubes and installation brackets. The range includes 4-, 5- and 7-inch options for compatible handheld angle grinders, plus 12- and 14-inch wheels for compatible stationary abrasive cut-off machines used for dry cutting.
Choose economical Super Tsurugi for routine carbon-steel work and suitable thin stainless steel, or evaluate the premium Super Raicho series when sharper cutting and longer usable disc life are priorities. Select the exact material-rated specification before ordering: diameter alone does not establish suitability.
Super Tsurugi cutting discs are the economical starting point for daily site cutting. Their double-layer reinforcing mesh supports the resin-bonded wheel structure. They suit contractors who want to balance purchase cost, cutting speed and frequent consumable use on ordinary carbon steel or suitable thin stainless sections.
Super Raicho cutting discs provide a premium option focused on cutting sharpness and durability. Compare an appropriate Raicho specification on repeated cuts when disc changes, operator time or edge cleanup contribute substantially to job cost. Performance depends on the material, section, machine and technique; there is no single speed or life improvement that applies to every site.
| Job priority | Selection starting point | Check on the job |
|---|---|---|
| Routine steel cutting with a controlled consumables budget | Super Tsurugi | Cost per accepted cut, cutting time and usable wheel life |
| Frequent cutting where sharpness and durability matter | Super Raicho | Repeated-cut performance, disc changes and edge cleanup |
| Larger sections or repeated cuts at a fixed station | 12- or 14-inch stationary cut-off wheel | Machine capacity, clamping and permitted wheel specification |
For exposed rebar that is authorized to be cut, select a steel-rated cutting disc and a grinder with adequate cutting capacity. Bar diameter, access and the ability to support the work determine whether a handheld grinder is appropriate. A smaller tool is convenient for local work; it is not a substitute for a larger cutting system when the section exceeds its capacity.
Secure the bar and control the offcut so that movement does not close the cut and pinch the wheel. Keep the disc aligned with the cut and avoid twisting or using its side for grinding. These metal-cutting discs are not a general solution for cutting through concrete surrounding embedded reinforcement. Confirm structural permissions and concealed services before altering installed materials.
Steel door and window fabrication often involves trimming hollow sections, angle steel, flat bar and brackets to installation dimensions. Select for wall thickness as well as overall section size. Thin sections require controlled feed and secure support; forcing a cut can increase distortion, burrs and rework.
Before preparing a batch, make a trial cut on matching stock and inspect length, squareness and edge condition. Deburr with a separate suitable abrasive if needed. Do not use a thin cut-off disc as a grinding wheel. For coated steel, protect adjacent finishes and plan ventilation and spark containment for the coating and work area.
For thin stainless trim or tubing, confirm that the chosen Super Tsurugi or Super Raicho specification is approved for that grade and application. Keep stainless work separated from carbon-steel contamination and check the required finish. Aluminum window frames require a separately approved aluminum-cutting solution; a steel or stainless disc is not automatically suitable.
Use 4- and 5-inch setups for suitable local cuts where access and handling are important. A compatible 7-inch grinder can provide more cutting reach, but its larger size and different handling must suit the job. Actual cutting depth depends on the tool, guard, wheel wear and workpiece geometry, not the nominal disc diameter alone.
Corded and cordless grinders both require these checks. A suitable thin disc may reduce cutting resistance, but battery runtime and cutting speed depend on the complete setup. Tool power, wheel size and access should be selected together; a compact tool does not make an awkward or overhead cut inherently safe.
Move larger metal sections or repeated stock preparation to a suitable fixed cutting station when its rated capacity and clamping arrangement fit the work. FUJI offers 12- and 14-inch resin cut-off wheels for stationary machines for dry metal cutting. Check the exact wheel diameter, bore, speed rating and material specification against the machine manual.
A stationary abrasive saw allows the work to be held in its designed vise and supported for repeat cuts. Check capacity for the particular round, square or rectangular section and cut angle. Even a 14-inch wheel does not guarantee that every large beam or pipe will fit. Use a different machine or process when capacity is insufficient.
Stationary wheels and handheld grinder discs are separate selections. Do not transfer a large stationary wheel to a handheld grinder, or assume that a toothed-blade cold saw accepts an abrasive wheel. Dry-cutting products must be used according to their instructions; do not add coolant to an unapproved setup.
For example, a contractor preparing steel door-frame sections can compare an appropriate Super Tsurugi and Super Raicho on the same stock and compatible tool. This is a suggested evaluation method, not a report of a measured customer project.
This comparison shows whether a premium wheel earns its place through productivity and durability, or whether the economical option already meets the job’s needs. Keep the result tied to the tested setup rather than treating it as a universal percentage improvement.
Super Tsurugi’s two reinforcing mesh layers are part of its construction, not a guarantee against breakage or kickback. Correct mounting, guarding, speed matching and work support remain essential. Follow the tool and wheel instructions, use suitable eye and face protection and other task-required PPE, and manage sparks, hot offcuts and combustible materials under the site’s hot-work procedures.
If access does not allow stable handling with the guard installed, change the work arrangement or cutting method. Stop if a wheel is damaged, binds or behaves unusually. For stone and tile work, see the separate FUJI 105mm diamond blade application guide; those materials require a different selection from the metal-cutting discs discussed here.
Which FUJI cutting disc is the economical option for steel?
Super Tsurugi is the economical starting point for routine carbon-steel cutting and suitable thin stainless work. Confirm the supplied specification for the material and machine.
When should I choose Super Raicho?
Consider the premium series when sharp cutting and durability are priorities. Evaluate total cost per accepted cut on representative material.
Can these discs cut steel window frames and rebar?
Suitable steel-rated versions can be selected for these tasks within the machine’s cutting capacity. Aluminum frames, embedded reinforcement and structural alterations require separate assessment.
Are 12- and 14-inch wheels used on an angle grinder?
No. The large wheels discussed here are selected for compatible stationary abrasive cut-off machines, with correct speed, guarding and clamping.
Does double reinforcement eliminate kickback?
No. Reinforcement does not remove the risks of pinching, twisting, overspeed or incorrect mounting. Correct selection and working methods remain necessary.
FUJI’s abrasive manufacturing history dates to 1953. For contractors, the practical value is selecting an appropriate resin cutting wheel for the material, tool and production requirement—from economical daily cutting to premium consumables for repeated work.
Send the metal grade, section dimensions, grinder or stationary saw model, permitted disc diameter and bore, maximum spindle speed and approximate daily cutting quantity. Include the required edge finish so FUJI can recommend a specification for evaluation.
