FUJI Tsurugi standard resin-bonded cut-off wheels for general steel pipes, bars, angle iron and sections.
FUJI Tsurugi (つるぎ) is a standard resin-bonded cut-off wheel series for general steel pipes, angle iron, bars and channel sections. This page covers the 100–255 mm range. Select the exact diameter, thickness, bore and speed rating for the approved cutting machine.
Tsurugi is a practical option for cutting steel stock to length before assembly, welding or maintenance. Evaluate cutting time, wheel consumption and the required cut quality on your actual section. Burr formation and service life depend on the material, machine and cutting conditions; neither a burr-free finish nor a fixed saving is guaranteed.
This standard series is distinct from Super Tsurugi thin cut-off discs. Do not transfer the Super Tsurugi dimensions, reinforcement specification or 80 m/s rating to this range.
| Diameter × thickness × bore (mm) | Specification |
|---|---|
| 100 × 2 × 15 | A46R BF |
| 110 × 2 × 20 | A46R BF |
| 125 × 2 × 22 | A46R BF |
| 150 × 2 × 22 | A46R BF |
| 180 × 2 × 22 | A46R BF |
| 205 × 2 × 22 | A46R BF |
| 255 × 3 × 25.4 | A46R BF |
The 2025 Japanese catalogue lists 72 m/s for these sizes. The 255 mm wheel is 3 mm thick, not 2 mm. A46R identifies the abrasive/grit and bond grade; BF identifies the reinforced resin bond. Check the delivered wheel label and machine instructions before use.
The catalogue marks 125 × 2 × 20, 160 × 2 × 20, 180 × 2 × 20 and 205 × 2 × 25.4 as discontinued after remaining stock. Confirm availability before ordering these legacy bores. Export specifications, if offered, require separate confirmation.
The catalogue application is general steel. For stainless steel, aluminium, plastics, tile or other materials, request a wheel explicitly specified for that material and operation. This listing does not establish contamination-free stainless cutting or universal multi-material compatibility.
Select FUJI Tsurugi cut-off wheels for general steel stock preparation in workshops and maintenance operations. The cutting task and machine determine the size required; wheel diameter alone does not establish cutting capacity.
Tsurugi offers a defined, catalog-listed range of resin-bonded steel cutting wheels, with A46R BF specification and several diameter and bore combinations. This makes it possible to select by the actual machine and steel section instead of choosing a disc from its nominal inch size alone.
The listed range uses 2 mm thickness through 205 mm diameter and 3 mm at 255 mm. For buyers, the useful comparison is cost per accepted cut: consider wheel consumption, cutting time and any subsequent deburring together. Run a controlled trial on representative stock before estimating savings or wheel life.
No. This page describes the standard Tsurugi series. Super Tsurugi thin cutting discs and larger EX-Tsurugi wheels are separate ranges with their own specifications.
No. Confirm the exact bore, flanges, guard and rated speed. The catalog size shown here is 180 × 2 × 22 mm; do not assume compatibility from the nominal 7-inch description.
No. The listed 255 mm version is 3 mm thick with a 25.4 mm bore. Select an approved cutting machine for this exact wheel.
Send the required wheel dimensions, machine details, steel section, expected quantity and a photo of the current wheel label. Confirm availability of legacy bore sizes before planning repeat supply.
Send the steel grade, section dimensions, wall thickness, machine model, speed, current wheel label and required quantity. We can then confirm the wheel specification and supply arrangement. Compare Super Tsurugi thin discs · Larger EX-Tsurugi wheels ·
Choosing the correct abrasive wheel is critical for both operational efficiency and JIS-compliant safety. Fuji Grinding Wheels are engineered with precise technical markings to ensure the perfect match for your specific material and machine requirements.
For professional export markets, always verify the Peripheral Speed (m/s) compatibility. Fuji wheels are designed to exceed JIS Burst Speed factors, but operating at the recommended R.P.M. ensures the longest tool life and cleanest cut.
Note: Mismatched grit or hardness can lead to excessive heat buildup, affecting the workpiece's structural integrity.
Global Maintenance Standard: To maintain the high safety factor of Fuji wheels, avoid exposure to excessive humidity and chemical solvents during storage. Proper care preserves the resinoid bond's strength, crucial for high-load industrial applications.
Fuji products are manufactured following strict Japanese standard process requirements. Every wheel is engineered to meet or exceed JIS (Japanese Industrial Standards), such as JIS R 6242 and B 4051. Our core engineering logic prioritizes maximum operator protection by maintaining safety factors and burst speed capabilities that often surpass the highest industry benchmarks.
| Standard Region | Safety Factor (Burst Multiplier) | Safety Logic & Benchmark |
|---|---|---|
| FUJI (High Precision) | > 2.0x | Engineered to exceed JIS requirements for maximum reliability. |
| Japan (JIS R 6242) | 2.0x | Extreme Safety: A wheel rated at 80m/s must withstand a 160m/s burst test. |
| Europe (EN 12413) | 1.73x | Risk Balanced: Provides high safety redundancy for most industrial apps. |
| USA (ANSI B7.1) | 1.5x | Efficiency Focused: Relies on machine guarding and operational procedures. |

When deploying Fuji high-performance tools in overseas markets, ensure that the regional power grid frequency and voltage match the tool specifications. To maintain the superior burst speed safety of Fuji wheels, store abrasives in a dry, temperate environment. Humidity can degrade the resin bond, potentially lowering the wheel’s resistance to centrifugal forces.
