The Diablo 3" Diamond Continuous Rim Masonry Cut-Off Disc is engineered for professionals who demand clean, precise cuts through granite, marble, porcelain, and tile. Featuring an ultra-thin continuous rim design and industrial-grade diamonds bonded to a hardened disc body, this 3" cut-off wheel delivers up to 60% smoother cuts compared to standard diamond cut-off discs - making it the ideal choice for tile work, natural stone fabrication, and demanding masonry applications where chip-free results matter.

Key Features

• Superior quality diamond edge rim design delivers up to 60% smoother cuts versus standard diamond cut-off discs - resulting in chip-free cuts without burn marks, reducing rework and material waste on finished surfaces
• Hardened disc body absorbs vibration and increases impact resistance - providing superior cut quality in hardened materials even during extreme applications, extending the working life of the disc
• Ultra-thin constant contact continuous turbo rim design provides precise cuts at high rates of speed - allowing faster, more controlled cuts through dense tile and natural stone without sacrificing accuracy
• Compatible with 3/8" arbor - fits standard 3" saws already found in most tile and masonry tool kits, requiring no special adapters
• Rated for both dry and wet cutting - offering flexibility on the jobsite whether a water source is available or not
• Maximum 20,000 RPM rating - supports full-speed operation on compatible 3" saws for efficient, high-throughput cutting
• Ultra-thin 1.4mm kerf and 1.3mm blade thickness - minimizes material loss per cut and reduces drag through hard stone and porcelain

Why This Product

• Cuts granite, marble, porcelain, and tile with up to 60% smoother results than standard diamond cut-off discs - making it a practical upgrade for tradespeople who need clean edges on expensive finish materials where chipping is unacceptable
• The continuous rim design combined with industrial-grade diamonds means the disc maintains cutting quality even in hardened and dense materials - reducing blade changes and downtime during intensive tile and stone work
• At 1.4mm kerf, this disc removes minimal material per pass - preserving more of the workpiece and allowing tighter tolerances in precision masonry and stone cutting tasks
• Wet and dry compatibility makes this disc versatile across different jobsite conditions - from indoor tile installations where water use is limited to outdoor stone cutting where wet cutting is preferred for dust control

Frequently Asked Questions

Can the Diablo DMADC0300 be used for both wet and dry cutting?

Yes. This disc is rated for both dry and wet cutting applications, giving you the flexibility to use it with or without water depending on your jobsite setup and dust control preferences.

What materials can this diamond cut-off disc cut through?

The DMADC0300 is designed to cut granite, marble, porcelain, and tile. Its industrial-grade diamond edge rim and hardened disc body are built to handle these dense, hardened materials even in demanding conditions.

What saw is this disc compatible with?

This disc is designed for use with a 3" saw and requires a 3/8" arbor. It has a maximum operating speed of 20,000 RPM, so always verify your saw's rated speed does not exceed this limit before use.

How does the continuous rim design affect cut quality compared to standard diamond discs?

The continuous rim design maintains constant contact with the material throughout the cut, which - combined with the superior quality diamond edge - produces up to 60% smoother cuts than standard diamond cut-off discs, resulting in chip-free edges without burn marks on finished surfaces like porcelain and polished stone.
