14 Inch Cutting Disc (355mm): Chop Saw Wheels for Heavy-Duty Cutting
The 14 inch cutting disc (355 mm) is the standard wheel for stationary and portable chop saws (cut-off machines). Engineered for heavy-duty applications, it delivers clean, fast cuts through high-density materials such as rail steel, cast iron, angle beams and heavy-gauge pipes.
Applications
- Metal chop saws in fabrication shops and steel service centers
- Cutting angle beams, channels, solid bar and heavy-wall pipe
- Railway maintenance: cutting rail steel and track components (16"/400 mm versions)
- Construction sites: batch cutting of rebar and structural steel
Advantages
- Deep, straight cuts: 100+ mm cutting capacity with the machine clamped for accuracy.
- Heavy-duty bond: enhanced resin formula withstands the sustained load of fixed-machine cutting.
- Stable performance: rated 4,300 RPM / 80 m/s with double fiberglass reinforcement.
- Multiple thicknesses: 1.9–3.0 mm options balance cutting speed against wheel life.
- Cost-effective: low cost per cut for high-volume repetitive work.
Specifications
| Size (mm) | Size (inch) | Max RPM | Max Speed |
|---|---|---|---|
| 300 × 2.5 × 25.4 | 12" × 1/10" × 1" | 5,100 | 80 m/s |
| 300 × 3.0 × 25.4 | 12" × 1/8" × 1" | 5,100 | 80 m/s |
| 355 × 1.9 × 25.4 | 14" × 1/13" × 1" | 4,300 | 80 m/s |
| 355 × 2.5 × 25.4 | 14" × 1/10" × 1" | 4,300 | 80 m/s |
| 355 × 2.8 × 25.4 | 14" × 7/34" × 1" | 4,300 | 80 m/s |
| 355 × 3.0 × 25.4 | 14" × 1/8" × 1" | 4,300 | 80 m/s |
| 400 × ≥3.0 (rail cutting) | 16" × 1" | 3,800 | 80 m/s |
How to Choose
- Confirm bore: 25.4 mm (1") is standard for chop saws; some machines need reducer rings.
- Thinner (1.9–2.5 mm) for speed and fine finish; thicker (2.8–3.2 mm) for maximum wheel life on solid bar.
- For stainless tubes, use dedicated stainless-grade wheels (fine abrasive, no burrs, no contamination).
FAQ
What machine uses a 14 inch cutting disc?
A 355 mm chop saw / abrasive cut-off machine. Always verify the machine's rated RPM is at or below the disc's 4,300 RPM maximum.
Can a 14 inch cutting disc cut stainless steel?
Yes, with a stainless-grade (INOX) 355 mm wheel. Standard wheels contain fillers that can contaminate stainless surfaces.
How long does a 14 inch chop saw wheel last?
On 50 mm solid steel bar, expect 30–60 cuts from a quality 3.0 mm wheel. Thin-wall tube yields far more. Wheel grade and operator technique are decisive.
