5 Inch 130mm Diamond Hole Saw with Pilot Bit - Deep Wet Cutting

In this review the 5 in 130mm Diamond Hole Saw with pilot bit is evaluated for tradespeople and serious DIYers who need large, clean holes in stone and tile. The single biggest reason to buy is its deep 1 3/8 in cutting depth combined with a removable pilot bit, which lets the tool bore through thick countertops and natural stone with minimal setup. The review focuses on performance on granite, quartz, porcelain and ceramic tile, and how the saw behaves when used wet with a standard corded drill.

Key Features

• Removable pilot bit: The included center pilot drill eliminates the need for special guiding tools and helps start holes accurately on smooth surfaces.
• Triple-layer diamond coating: Heavy diamond plating improves longevity and maintains cutting quality across hard materials like marble and granite.
• 1 3/8 in cutting depth: Increased hole saw body height allows drilling through thicker countertops and tiles in a single pass without frequent repositioning.
• Triangular 3/8 in shank: The standard shank fits most corded drills securely and reduces slippage during tougher cuts.
• Wet use recommended: Designed for wet cutting to reduce dust and heat, producing smoother, cleaner edges on sensitive materials like glass and porcelain.
• Solid steel body: A robust construction gives stable, straight holes and resists deformation under load.

Who It's For

This hole saw suits tile installers, countertop fabricators, and homeowners doing remodels who need to cut large diameter holes through stone, porcelain, ceramic tile, marble and glass. The depth and diamond coating make it appropriate for creating sink, fixture and plumbing openings in thick quartz or granite counters.

Those who should look elsewhere are casual users who rarely drill stone and prefer a smaller, cheaper bit, or anyone who needs a dry-cut solution for delicate indoor work; this blade is optimized for wet cutting and standard corded drills rather than compact battery tools.

Pros & Cons

Pros

• Cuts through thick countertops and natural stone with clean edges thanks to the deep body and diamond coating.
• Removable pilot bit makes positioning straightforward on slippery or glazed tile surfaces.
• Standard 3/8 in triangular shank fits common drills and limits bit rotation under load.
• Wet use reduces dust and heat, improving cut quality on glass and porcelain.

Cons

• Performance on speed and long-term durability varies by user and material; expect mixed reports on cutting speed depending on stone hardness.
• Requires wet cutting setup, which may be inconvenient for some workshop or field situations.
