Diablo Grinding Disc DBD070250701C 7 In x 1/4 In 5/8-11 Hub (8450 RPM Silicon Carbide Type 27 Depressed Center Concrete Brick Masonry Wheel)

High-Performance Diablo 7 Inch Type 27 Depressed Center Masonry Grinding Disc DBD070250701C

The Diablo 7-Inch x 1/4-Inch Type 27 Masonry Grinding Disc (DBD070250701C) operates as a heavy-duty abrasive wheel engineered to execute rapid stock removal, surface smoothing, and edge beveling on concrete, brick, and cinder block substrates. Formulated with a high-grade silicon carbide grain blend reinforced with fiberglass mesh, this 0.25-inch thick depressed center disc features an integrated 5/8-11 threaded hub rated for operation up to 8,450 RPM. Compatible with standard 7-inch industrial angle grinders, this fully reinforced masonry wheel provides low-angle surface grinding and flush-cutting capability without premature wheel breakdown on hard stone materials.

Best Used For:

• Concrete Surface Smoothing & Levelling: Grinding down rough pour seams, high spots, and form marks on poured concrete walls, slabs, and footings.
• Masonry Paver & Brick Shaping: Beveling edges and removing excess mortar from clay bricks, concrete pavers, and retaining wall blocks.
• Cinder Block Prep & Tuckpointing Cleanout: Shaping heavy cinder blocks and smoothing out mortar joints prior to waterproof coating applications.

Key Performance & Safety Features

• Premium Silicon Carbide Grain Blend: Ultra-hard mineral formulation continuously fractures under high stress to maintain aggressive cutting action on abrasive masonry.
• Type 27 Depressed Center Geometry: Sunken hub design enables shallow 15-to-30-degree grinding angles for flush surface leveling and tight corner access.
• Integrated 5/8"-11 Threaded Steel Hub: Allows direct spin-on mounting to standard large angle grinder spindles without requiring separate flange nuts.
• Full Fiberglass Mesh Reinforcement: High-tensile inner fiberglass layers prevent wheel fragmentation under side-load grinding stress.
• 8,450 RPM Maximum Velocity Rating: Precision-balanced construction supports continuous full-speed operation on heavy-duty commercial angle grinders.
• 0.25-Inch Heavy-Duty Profile: Thick abrasive cross-section resists edge wear during aggressive material removal and gouging tasks.

What's Included

• (1) Diablo 7" x 1/4" x 5/8"-11 Type 27 Masonry Grinding Disc (Model DBD070250701C)

Technical Specifications

Pro-Tip: When grinding high spots on cured concrete slabs with this 7-inch 5/8-11 disc, maintain a consistent 15-to-20-degree angle relative to the work surface and let the 8,450 RPM speed do the work without applying excessive down-force. Applying light, sweeping pressure allows the silicon carbide grains to self-sharpen cleanly, preventing heat glaze and maximizing wheel life.
