Expert FAQ: Technical Terms & User Concerns
Frequently Asked Technical Questions
-
Q: What is the material composition of angle grinder stone cutting discs?
A: These discs typically feature high-purity aluminum oxide abrasive, layered fiber mesh (for reinforcement), and a phenolic resin binder. Some “granite cutting disc for angle grinder” models also embed diamond grains for extra hardness. -
Q: What does ISO 15636 certify?
A: ISO 15636 is an international standard covering the safety, design, and performance requirements for abrasive products used for cutting/construction on stone, concrete, and masonry substrates. It mandates testing for dynamic balance, breakout resistance, and humidity aging. -
Q: What is the recommended installation torque for 115mm discs?
A: The disc should be mounted on an angle grinder spindle adapter and torqued to 15–20 Nm (as per ANSI B7.1), to prevent slippage or over-torque cracking. -
Q: How often do discs require inspection?
A: Inspect angle grinder stone cutting discs before each use for wear, cracks, or imbalance (max 0.25mm lateral runout). Use only discs with intact batch/ISO labeling and expiry within 3 years of production. -
Q: Are custom grit discs (e.g., 60# vs 100#) better for certain stones?
A: Yes. Finer grit (e.g., 100#) creates a smoother surface, suitable for granite and high-finish applications; universal (80#) is optimal for general concrete/stone. -
Q: What is the expected service life in industrial use?
A: For reinforced 115mm discs: typical working life is 50–70 minutes of continuous cutting (varies with stone type and pressure). That’s 20–38% longer than non-reinforced, entry-level discs. -
Q: Do these discs support wet cutting?
A: Yes, they are water-resistant and suitable for both dry and wet cutting, increasing lifespan and reducing dust—important for granite and stone slabbing work.
