Cut-off Wheel NORTON NOR-Quantum 3 NQ46ZZ 125x1.6x22.23 T41 — 125 mm abrasive cutting disc

NORTON NOR-Quantum 3 NQ46ZZ 125x1.6x22.23 T41 is a 125 mm cut-off wheel designed for precise, high-speed abrasive cutting on angle grinders. With a 1.6 mm thin cutting thickness and a 22.23 mm centre bore, this T41-shaped disc is intended for fast, low-resistance cutting of various metals and metal assemblies where a thin kerf and controlled heat generation are important. The disc is suitable for professional workshops and industrial environments that require reliable, repeatable results from an abrasive cutting wheel.

Advantages

The thin 1.6 mm thickness provides a narrow kerf for faster cutting and reduced material loss while minimizing heat build-up. The 125 mm diameter and balanced construction allow stable rotation at typical angle grinder speeds, supporting consistent performance and longer usable life under rated operating conditions. The T41 shape and reinforced bond deliver improved edge integrity and controlled wear during repeated metal cutting tasks.

Suitable for

• Cutting steel bars, rods, and profiles
• Trimming welded joints and removing weld beads
• Shearing sheet metal and thin plate material
• Workshop and on-site metal fabrication tasks
• General-purpose metal cutting with an angle grinder

Key specifications

• Diameter: 125 mm
• Thickness (kerf): 1.6 mm
• Centre bore: 22.23 mm
• Shape: T41 (flat, reinforced cutting disc)
• Intended use: Abrasive cutting of metals

How to use

Fit the cut-off wheel onto a compatible 125 mm angle grinder with a 22.23 mm arbor or suitable adapter, ensuring the disc is mounted in the correct orientation and secured with the provided flange and nut. Always verify the grinder’s maximum RPM does not exceed the disc’s rated speed before operation. Hold the angle grinder with both hands, apply steady, even pressure, and allow the abrasive to do the cutting; avoid forcing the disc through the material. Maintain a consistent cut line and withdraw periodically to inspect the disc and workpiece for heat or damage.

Usage recommendations

For safety and optimal results, use appropriate personal protective equipment including eye protection, hearing protection, and gloves. Use wheel guards and follow the angle grinder manufacturer’s instructions. Store discs flat in a dry environment and do not use if cracked, chipped or excessively worn.
