Description

Overview: Precision in Compact Form

The FUJI 70x2mm Mini Grinding Wheel is a precision abrasive tool engineered for detailed metalworking tasks. Crafted by FUJI in Japan, this wheel features a Depressed Center (Type 27) design, optimized for light grinding, deburring, and spot weld removal.

Specifically designed as the dedicated accessory for the HSF-50F T2 Micro Sander, it combines high-performance alumina with a durable resin bond. This ensures safety, longevity, and surgical precision in tight spaces where standard 4-inch wheels simply cannot fit.

Why Choose FUJI Mini Wheels?

🎯 Compact Precision At just 70mm (2.75 inches), this wheel supercharges the functionality of compact sanders. It allows you to execute precise grinding tasks in deep corners, narrow channels, and intricate machinery components.
⚙️ Optimized for HSF-50F Engineered to work in perfect harmony with the FUJI HSF-50F series. The weight and balance are tuned to the machine's motor, reducing vibration and guaranteeing a smooth, professional finish.
🛡️ Durability & Quality Made with premium High-Performance Alumina particles. The abrasive grains are securely bonded to prevent premature shedding, significantly extending service life even on tough steel.
📐 Depressed Center Design The offset center allows the locking nut to sit flush, enabling the operator to grind at flatter angles (15°-30°) without the spindle interfering with the workpiece.

Frequently Asked Questions

Q: Can I use this wheel on a standard 4-inch angle grinder?
A: No. This is a 70mm wheel designed for mini grinders like the HSF-50F. Standard 4-inch grinders use 100mm wheels and have different guard sizes and RPM ratings.
Q: What materials can I grind with this wheel?
A: It is suitable for general ferrous metals, including mild steel, carbon steel, and cast iron.
Q: Is a safety guard required?
A: Yes, absolutely. Even with mini grinders, you must always use the appropriate safety guard provided with your HSF-50F tool to protect against debris.
