Cut-Off Wheel GRAPHITE 255×30 mm T40 57H686 for Angle Grinders

GRAPHITE Cut-Off Wheel 255×30 mm T40 is a reinforced abrasive disc designed for use with angle grinders that accept a 30 mm arbor. With a 255 mm diameter and flat profile, this cutting wheel is intended for making straight, accurate cuts in metal and similar materials. The wheel’s geometry and abrasive composition are optimized for clean sectioning of pipes, profiles, sheet metal and other ferrous workpieces in professional and DIY metalworking environments.

Advantages

The reinforced construction reduces vibration and helps maintain stable rotation at typical angle grinder speeds, improving cut quality and operator control. A medium-thickness profile balances cutting speed and disc durability, enabling efficient progress on longer cuts while preserving wheel life. The 30 mm center hole ensures secure mounting and concentricity on compatible grinders, contributing to safer operation and reduced runout.

Suitable for

• Cutting steel pipes and tubes
• Sectioning metal profiles and beams
• Separating sheet metal and metal plates
• On-site metal fabrication and repair tasks
• DIY workshop projects requiring straight, quick cuts

Key specifications

• Diameter: 255 mm
• Arbor bore: 30 mm
• Shape/profile: flat cutting disc (T40)
• Typical application: cutting ferrous metals and similar materials
• Construction: reinforced abrasive wheel for improved stability

How to use

Mount the cut-off wheel on an angle grinder compatible with a 30 mm arbor and the disc’s diameter. Ensure the disc is installed in the correct orientation and securely tightened according to the grinder manufacturer’s instructions. Before cutting, verify the wheel and grinder are in good condition, that protective guards are fitted, and that appropriate personal protective equipment (eye, hearing, and hand protection) is worn. Start the grinder and allow it to reach full speed before applying the wheel to the workpiece, and use steady, even pressure—do not twist or force the disc. After cutting, let the wheel come to a full stop before setting the tool down.

Usage recommendations

Do not use the wheel on grinders or applications that exceed the disc’s rated speed; follow the angle grinder manufacturer’s safety limits. Use cutting techniques appropriate for metal: maintain a perpendicular approach for straight cuts, avoid side loading, and replace the wheel if you observe excessive wear, cracks, or vibration. Store discs flat in a dry area to prevent damage and contamination.
