Vacuum-brazed diamond drill bits with built-in cooling wax help make drilling tile, glass and stone simpler, cleaner and more convenient with compatible power drills.
Built-In Cooling Wax Vacuum-Brazed Diamond 1/4" Hex Shank 6 Useful Sizes
Upgrade Your Drill Setup
WHY IT WORKS BETTER
Built for the Materials Standard Bits Hate
The right cutting surface, cooling support and shank design make hard-surface drilling far more manageable.
Tough Surface? Bring Diamond Grit.
A vacuum-brazed diamond cutting layer gives the bit an aggressive working surface for hard materials where conventional drill bits can struggle, skate or wear quickly.
Chuck It In and Get to Work
The standard 1/4-inch hex shank offers quick, secure installation with many cordless drills and electric hand drills—no complicated adapter setup for everyday jobs.
One Bit Style for More of Your Projects
Use it for common renovation and installation materials including porcelain tile, ceramic, glass, marble, granite, jade and quartz stone. Great for fixture holes, hardware installation and DIY upgrades.
Pick the Hole Size Your Project Actually Needs
Available in six commonly used diameters so you can match the bit to anchors, fittings, hardware and other installation requirements instead of forcing one size to do every job.

BEFORE YOU START
Frequently Asked Questions
Do I need to continuously add water while drilling?
The bits contain built-in cooling wax and are designed to support dry drilling, so continuous external water feeding is not normally required. Always follow appropriate drilling practices for your specific material and application.
What materials can I drill?
They are intended for hard surfaces such as porcelain tile, ceramic, glass, marble, granite, jade, quartz stone and similar masonry or stone materials.
Will these bits fit my cordless drill?
The bits use a standard 1/4-inch hex shank and are compatible with many common cordless and electric drills. Check your drill chuck or bit holder before ordering.
What sizes are available?
Available diameters are 6mm, 8mm, 10mm, 12mm, 14mm and 16mm. Choose the size that matches your fixture, anchor or installation.
Why use vacuum-brazed diamond instead of a standard bit?
The diamond-coated cutting surface is specifically suited to hard materials that conventional metal drill bits may struggle to cut efficiently.
Can beginners use these bits?
They can be used for DIY work, but hard-surface drilling requires controlled speed and technique. Starting the hole at a slight angle can help prevent the bit from skating across smooth surfaces.
How can I help extend bit life?
Avoid excessive force, use an appropriate drill speed, allow the bit to cool between demanding cuts, and use the correct bit diameter for the job.
