Specification

Description

Type 11 resin bonded aluminum oxide cup wheels deliver aggressive grinding power in a compact, versatile form factor for portable, hand-held machines such as angle grinders. Designed for foundry and primary metal applications, these cup wheels excel at removing weldments, casting flash, and metal trees with speed and control. The resin bond ensures durability under heavy grinding loads, while the tough aluminum oxide grain maintains sharp cutting edges for consistent performance. With their cup shape, these wheels provide a broad grinding surface, improving contact with workpieces and enhancing operator efficiency in demanding environments.

Features

Aluminum Oxide Grain—Engineered for ferrous metal grinding, offering toughness and cutting efficiency on steel and iron.
Cup Wheel Geometry (Type 11)—Provides a versatile contact area for stable grinding, enabling smooth material removal and easier control on irregular surfaces.
Resin Bond System—Ensures grain retention under heavy load, improving wheel life and maintaining consistent performance.
Portable Machine Compatibility—Designed for use on angle grinders and similar hand-held tools, giving operators mobility in demanding work areas.
Heat-Resistant Design—Helps manage grinding heat buildup, reducing risk of burn marks and improving finish quality.

Application

1
Grinding and smoothing weld seams on heavy steel fabrications.
2
Removing casting flash, fins, and parting lines from iron or steel castings.
3
Reducing gates, risers, and metal “trees” in foundry cleaning rooms.

Recommendations

Always mount securely on properly rated hand-held grinders with guards in place.
Use firm, controlled pressure to maximize material removal without overloading the wheel.
Avoid excessive side pressure—cup wheels are designed for face grinding, not edge use.
Wear appropriate PPE (eye, face, gloves, and hearing protection) during operation.
Inspect wheels before each use for cracks, chips, or damage to ensure safe grinding.
