Why Choose This Abrasive Wheel?

• Bakelite Aluminum Core Base: The lightweight composite core keeps the wheel balanced and stable under load. It will not crack under normal operating conditions, eliminating the risk of flying fragments during use.
• 100% Diamond Concentration: Full diamond loading means a sharper, faster-cutting surface that stays effective longer than conventional resin wheels.
• Two Grit Options: Choose P240 for aggressive stock removal and shaping, or P400 for fine finishing and a smooth surface ready for final polishing.
• Two Thickness Options: Select the 2 mm wheel for precision narrow-profile cuts or the 5 mm wheel for added stability and wider grinding passes.
• Versatile Applications: Engineered for cutting, grinding, and polishing hard and brittle materials — tungsten carbide, glass, ceramics, ferrite, semiconductors, electrical carbon products, precious stones, refractory materials, magnetic materials, iridium alloy, and blade tooling.
• Safe Operating Speed: Rated up to 3,500 RPM to work with a wide range of bench grinders and surface grinders.

Applications

This abrasive disc is ideal for metalworking shops, lapidary studios, ceramics workshops, electronics manufacturing, and precision tool-and-die operations. Whether you are shaping jade cabochons, truing carbide tooling, or finishing glass edges, the JX-150 provides consistent, repeatable results.

Frequently Asked Questions

Q: What materials can the 150mm resin diamond abrasive wheel grind and polish?

A: The RAMS BRALIN JX-150 resin diamond abrasive wheel is designed for hard and brittle materials including tungsten carbide, glass, ceramics, ferrite, semiconductors, electrical carbon products, precious stones, jade, refractory materials, magnetic materials, iridium alloy, and cutting tool edges. Its 100% diamond concentration ensures sharp, efficient material removal across all these substrates.

Q: What is the maximum safe operating speed for this abrasive disc?

A: The maximum rated speed is 3,500 RPM. Always ensure your bench grinder or surface grinder does not exceed this speed, and use appropriate personal protective equipment including eye protection and gloves when operating any abrasive wheel.

Q: Which grit should I choose — P240 or P400?

A: Select P240 if you need faster stock removal, shaping, or coarser grinding of hard materials. Choose P400 for finer finishing passes where a smoother surface finish is required before final buffing or polishing. Both grits are available in 2 mm and 5 mm thickness options.

Q: What is the difference between the 2 mm and 5 mm thickness options?

A: The 2 mm wheel is ideal for narrow-profile cuts and precision slotting, while the 5 mm wheel offers a wider contact surface for more stable flat grinding and lapping operations. Choose based on the geometry of your workpiece and the type of operation you are performing.
