Standard Abrasives™ Type 27 Unitized Wheel

A 4-1/2" Type 27 unitized grinding wheel designed for right‑angle grinders, offering a soft‑to‑medium density for light‑pressure finishing, blending and polishing of metal surfaces.

Key Features

• Depressed center (Type 27) fits 4‑1/2" right‑angle grinder, allowing access to internal angles
• Soft/medium density material reduces required pressure for fine finishes
• Silicon carbide abrasive works on ferrous, non‑ferrous, exotic metals, titanium and composites
• Open‑web, load‑resistant construction extends service life and prevents smearing
• Runs both clockwise and counter‑clockwise for greater versatility
• Non‑woven nylon strands resist melting or smearing when heated

Specifications

• Overall Diameter: 4‑1/2 in (wheel size)
