5-Piece Dry Diamond Core Drill Bit Set – Vacuum Brazed With Hex Shank, For Ceramic, Porcelain, Marble, Glass, Granite & Quartz (¼" To ½")

About This Product

This diamond core drill bit set gives you five solid pieces that'll chew through tile, marble, granite, glass, and brick like butter.
You get four dry diamond bits in ¼", 5/16", 3/8", and ½" – which covers most common hole sizes for plumbing, electrical, or mounting anchors.
Plus there's a bonus ¼" carbide hammer drill bit with a YG6X carbide tip for blasting into concrete and masonry.

What makes these special is the vacuum brazing tech.
Basically, the diamond grit is bonded to the steel core at a super high temp, so the diamonds stay put and keep cutting way longer than cheap electroplated bits.

These are dry drill bits, which is a huge convenience.

They've got a ¼" hex shank that fits most corded drills, cordless drills, and benchtop drills – no special adapter needed.
Just pop one in and start cutting.
Just remember: these are for hard, brittle materials like tile and stone.
Don't try them on wood or soft metals – they'll clog up and you'll be sad.
