A 105 × 1 mm cut-off wheel is a thin abrasive disc for cutting with a compatible handheld grinder. For metal fabrication shops in the Philippines and Southeast Asia, the useful question is whether it produces an acceptable cut at a competitive total cost. Wheel thickness alone cannot establish speed, life or suitability for a material.
This guide explains how to select and trial FUJI Super Tsurugi 105 × 1 mm cutting discs, and when to compare other sizes or formulations.
What 105 × 1 mm Means—and What It Does Not
The first dimension is the nominal outside diameter; the second is thickness. The bore, wheel shape, approved material and maximum operating speed are also required before selecting a disc. “4-inch” is a trade description: do not assume that a grinder approved only for 100 mm wheels accepts a 105 mm disc.
A thin cutting edge can reduce the amount of material removed compared with a thicker cut-off wheel. Actual kerf, heat, burr formation and cutting time depend on the formulation, workpiece and operating conditions. A 1 mm disc is not a grinding wheel and must not be used for side grinding.
Check the Machine and Material Before Ordering
| Check | Information to confirm |
|---|---|
| Diameter and mounting | Approved wheel diameter, bore, flange arrangement and wheel type in the grinder manual; dimensions on the actual disc label. |
| Speed | The grinder's maximum speed must not exceed the wheel's marked maximum operating speed. Do not infer the limit from diameter alone. |
| Guard and operation | A guard approved for cutting, correct mounting and the manufacturer's instructions for the tool and disc. |
| Workpiece | Material grade, section thickness and shape. Stainless steel, aluminum and cast iron require a product explicitly approved for the intended material. |
| Finish requirement | Required cut accuracy, acceptable burr and whether a later deburring or finishing operation is allowed. |
For stainless steel, request the exact product's INOX suitability and any contamination specification required by the customer. Do not infer iron, sulfur or chlorine limits from a brand name. Electric, pneumatic and high-frequency grinders each require these compatibility checks.
Choosing Between FUJI Cutting Disc Options
Super Tsurugi: evaluate the 105 × 1 mm option for routine metal cutting where a narrow cut and consumable cost matter. Confirm the offered specification and material application before testing.
Super Raicho: compare the Super Raicho thin cutting disc range when assessing alternative thicknesses and cutting behavior. It is a separate product choice, not another name for every 105 × 1 mm disc.
Larger wheels: select a larger diameter only for equipment approved for it. More diameter is not a remedy for forcing an unsuitable handheld setup into a deep cut. The FUJI cutting wheel application guide connects handheld and larger-machine options.
Single and Double Mesh: Read the Whole Specification
Fiberglass reinforcement forms part of a resin-bonded cutting wheel's structure. Mesh count alone does not prove cutting speed, suitability or safety: formulation, dimensions, reinforcement design and testing all matter. Ask for the exact offered product's documentation.
Neither single nor double reinforcement permits twisting, binding or lateral grinding. Secure the workpiece and use the wheel only for its approved operation. Stop if there is abnormal vibration or damage, and follow the manufacturer’s inspection, guarding, protective equipment and storage instructions.
Use a Repeatable Cutting Trial
The existing FUJI comparison video below can help start a product discussion. A demonstration is not a guarantee of a fixed speed or life advantage across different materials, grinders or operators. Ask for the full test conditions before applying a result to your production line.
- Define the job: record material grade, section dimensions, cut length and the acceptance criteria for the finished cut.
- Keep the setup comparable: use compatible equipment, equivalent wheel specifications and a consistent documented procedure within all operating limits.
- Test several discs: record time per accepted cut, usable cuts per disc, wheel changes and any rework. One fast cut does not establish expected life.
- Compare total cost: include abrasive consumption, labor, changeover time and finishing, rather than purchase price alone.
Abrasive cost per accepted cut = cost of discs consumed ÷ number of accepted cuts. Record why a cut was rejected. Keep results for each material separate; a steel-tube result does not establish performance on stainless plate.
Frequently Asked Questions
Will a 105 mm disc fit any 4-inch angle grinder?
No. Check the approved diameter, bore, wheel type, flange, cutting guard and speed. A matching bore alone is not enough.
Does a 1 mm wheel eliminate burrs and heat discoloration?
No. Thin wheels may reduce material removal, but cut quality depends on the complete application. Include burrs, discoloration and finishing time in your trial criteria.
How many cuts should one disc produce?
There is no universal number. Material, cross-section, machine and technique affect consumption. Compare multiple samples on your actual job.
What should I send for a recommendation?
Send the material grade, section dimensions, grinder model, current wheel label, monthly consumption and delivery country. For distribution purchases, use the wholesale cut-off wheel procurement checklist.
