4-1/2" x 1/4" x 5/8-11" Grinding Wheel (Type 27)

Tackle tough surface preparation and aggressive material removal with the Milwaukee 49-94-4515 4-1/2" x 1/4" Type 27 Grinding Wheel. Built with an A24R aluminum oxide formulation, this depressed-center wheel delivers consistent stock removal on metal, concrete, rust, scale, and masonry. The integrated 5/8"-11 threaded hub enables fast, tool-free wheel changes directly onto compatible small angle grinders. Precision-tested for balance to reduce tool chatter and operator fatigue, it provides smooth, vibration-free performance across industrial fabrication, masonry cleanup, and jobsite maintenance.

Key Features:

• A24R Aluminum Oxide Grain: Formulated for aggressive stock removal, weld blending, and masonry cleaning.

• 5/8"-11 Threaded Arbor: Thread-on hub enables rapid, wrench-free mounting onto standard 4-1/2" angle grinders.

• Precision Balanced Design: Individually balance-tested to minimize vibration, chatter, and uneven wear during operation.

• Multi-Material Capability: Cleans concrete, strips rust and scale, grooves troughs, and handles light asphalt dressing.

• Type 27 Depressed Center: Allows optimal clearance when grinding at shallow angles (15° to 30°).

• Specifications: Diameter: 4-1/2" (115 mm) | Thickness: 1/4" (6.3 mm) | Hub: 5/8"-11 Threaded | Max RPM: 13,300
