Crowne Tools Ultra Thin Wall Hole Bit For Ceramics and Glass

Crowne Tools Ultra Thin Wall Hole Bit: Diamond Hole Saw for Porcelain and Glass

The Crowne Tools Ultra Thin Wall Hole Bit is a professional-grade sintered diamond hole saw engineered for exceptionally clean, precise drilling in hard porcelain tile, ceramic tile, and selected glass surfaces. Designed for demanding tile and glass applications, this advanced hole bit combines ultra-thin wall technology with long-lasting sintered diamonds to deliver superior cutting performance with minimal chipping.

Its revolutionary 1 mm ultra-thin wall construction significantly reduces surface pressure during drilling, helping prevent cracks, edge damage, and material blowout commonly associated with traditional hole saws. This makes it especially effective when working with fragile or polished surfaces where finish quality is critical.

Unlike standard electroplated bits, the Crowne hole bit utilizes sintered diamond technology, where premium industrial diamonds are embedded throughout a durable metal bond matrix. This design provides faster drilling speeds, cleaner cuts, improved durability, and longer overall tool life — even on extremely dense porcelain materials.

Optimized for wet drilling applications, the bit performs best with water cooling to maintain lower operating temperatures, reduce dust, and maximize cutting efficiency. The result is smooth, chip-free 1" - 2" holes suitable for plumbing penetrations, drains, fixtures, electrical openings, and precision installation work.

Featuring a standard 5/8"-11 thread connection, the Crowne Ultra Thin Wall Hole Bit integrates seamlessly with most professional angle grinders and drilling tools used by tile installers, fabricators, and contractors.

For professionals who require flawless results on premium tile and delicate materials, the Crowne Ultra Thin Wall Hole Bit delivers precision, speed, and reliability in every cut.
