Dry and wet drilling versatility

The bits are built to perform in both dry and wet drilling scenarios, giving you flexibility depending on the material and environment. Whether you’re creating clean openings in a porcelain tile backsplash or penetrating a dense brick veneer, these bits are designed to respond predictably to your workflow.

Performance you can count on

High-quality diamond grain supports fast and smooth drilling, reducing drag and chatter while delivering precise holes. The 10mm diamond height promotes steady cutting while helping you maintain a steady hand and reduced breakage risk on tough surfaces.

Durability and cooling design

Inside each bit, dense cooling wax works with the vacuum-brazed diamond surface to help manage heat during drilling. This design aims to preserve the sharpness of the cutting edge and extend service life under typical use conditions.

Usage tips and compatibility

• Ensure a proper adapter is used if your machine doesn’t natively support 5/8-11 threads.
• Work at a steady pace with light, even pressure to maximize cut quality and minimize wear.
• For wet drilling, apply a light splash of water to cool the bit and reduce dust and friction.

Ideal for tile installers, renovators, and DIY enthusiasts, this SHDIATOOL pair offers a compact, capable option for precise hole cutting in tough materials. Use them for creating openings in porcelain tiles, marble surfaces, stone, masonry, and brick with a focus on clean edges and reliable performance.
