Small Hole. Clean Cut. Get It Done.

 

The 12mm Needle D's Diamond Drill Bit is built for fast, precise holes through porcelain, ceramic and stone using a standard drill or impact driver.

The 1/4" hex shank makes it quick to chuck up, while the diamond cutting edge handles the hard materials standard drill bits weren't made for.

Perfect for anchors, fixtures, accessories and those everyday holes tile installers drill constantly.

CHUCK IT. DRILL IT. DONE.

BUILT FOR TILE

  • 12mm / 1/2" Diameter — A versatile size for fixtures, anchors and installation work.

  • Dry-Cut Capable — Convenient for quick holes without setting up constant water cooling.

It'd be great if I could get the core out of the drill bit. Gets jammed up and I cant drill anymore holes with it.

Amazing little bits

I love these bits. They last twice as long as other brands and they give you better control when coring holes through tile.

Lasted 2 holes with water cooling

Bought 2 bits since I install a lot of shower accessories. Used water cooling system when drilling, first bit lasted 2 holes and barely started a 3rd until the tip was shiny and dull. Thought it was a dud, until the 2nd bit lasted the same amount of time. Got 4.5 holes out of 2 brand new bits. My cheapo Amazon ones lasted much longer.

Disapponted and definitely would not recommend.

Mixed results

I bought a few of these sized bits and had mixed results with longevity. One drilled 22 holes in ceramic tile submerged in water with the next one only drilling 6 holes before the end was just metal.
Same drilling style and pressure. I did buy 5 more to try, I’ll review them soon

Core bit review

Honestly I didn't get to use the bits that I paid for. A following trade was having issues dealing with the 7/8" porcelain material we installed and I offered my bits as a possible solution. I was assured that they performed far better than the hardware store solution at 25% of the price
