6ft Dry Diamond Core Drill Bit 152mm Tile Hole Saw - Precise Wet/Dry

In this review of the 6' Dry Diamond Hole Saw from DKIBBITH the bottom line is simple: this tool is aimed at tradespeople and experienced DIYers who need to cut clean 6' (152mm) holes in hard tile and stone for fixtures and ductwork. The single biggest reason to buy is the combination of a full 6' diameter cutting face with a high quality diamond tip and a 5/8-11 thread that fits standard angle grinders, letting users make large, accurate holes in porcelain, ceramic, granite and marble without complicated setups.

Key Features

• 6' Diameter: Produces a true 6' (152mm) hole size suitable for faucets, drains and ventilation cutouts without secondary trimming.
• High Quality Diamond Tip: The diamond cutting edge delivers consistent cutting performance on hard materials like granite and porcelain for longer life.
• 5/8-11 Thread Fit: Female 5/8-11 connection fits most angle grinders and wet polishers so it can be used with common, readily available tools.
• Slot for Debris Removal: A side slot helps clear dust and debris during cutting so dust buildup does not impair progress.
• Max Cutting Depth: With up to 2' cutting depth it handles thicker tile and stone applications commonly found on countertops and walls.
• Easy Cooling Tip: Designed for dry use but can be cooled by dipping or pausing, which helps manage heat and extend bit life.

Who It's For

This diamond hole saw is best for professional tilers, plumbers and installers who regularly cut large holes for fixtures in hard surfaces, and for experienced DIYers comfortable using an angle grinder. The solid 5/8-11 fit and the 6' diameter make it especially useful when installers need a single tool that works across porcelain, ceramic, marble, granite and other natural stone.

Those who should look elsewhere include beginners who lack experience with high-speed grinders or anyone who needs a smaller, more delicate hole size; the tool is large, requires control at high RPMs and benefits from an accessory guide or steady technique to get accurate start grooves.

Pros & Cons
