What makes this set unique
Designed specifically for hard tile and glass, the carbide-tipped bits in the ARTU Porcelain Plus line resist dulling far longer than standard bits. The 1/4" straight shank fits most common drill chucks, while the 4-1/2" overall length and 2-3/8" flute length strike a balance between control and depth, enabling precise entry holes for hardware, fixtures, and mounting plates. With a dedicated 5/16" drill size, you can create clean, finished holes without chiseling or excessive pressure.
Ideal for
- DIY remodelers tackling tile installation, fixture mounting, or glass interfacing projects
- Tile installers working with porcelain, ceramic, or glass tiles
- Homeowners upgrading bathrooms, kitchens, or glass tabletops who require durable, reliable bits
Use cases and benefits
- Openings for towel bars, shower heads, outlets, or lighting in porcelain or glass tile without micro-fractures
- Creating through-holes in glass tabletops or glass backsplash panels with cleaner edges
- Reliable performance in hard tile applications where standard bits wear quickly
How to get the best results
- Mark the drilling spot on the tile or glass, then apply a small piece of masking tape over the area to reduce wandering and chipping.
- Secure the workpiece and set your drill to a slow, steady speed suitable for tile and glass; avoid high RPM that can overheat the carbide tip.
- Apply light, consistent downward pressure. Let the bit do the cutting—too much force can cause fracture.
- Keep the work cool with a continuous spray of water or a damp cloth to prevent overheating and to improve edge quality.
- Once the hole is through, pause before withdrawing to prevent pinching or cracking the surrounding material.
Care and longevity
Rinse and wipe the bit clean after use to remove dust and debris. Store in a dry place to preserve the carbide tip integrity for long-term performance. This two-piece set is a cost-effective choice for ongoing projects where frequent, reliable tile and glass drilling is needed.
