Vacuum Brazed Bonding
Unlike standard electroplated drill bits, our high-vacuum furnace process creates a mechanical bond between steel body and diamond grit, quadrupling tool longevity and resistance to heat breakdown.
Vacuum Brazed & Thin Kerf Diamond Tile Drills
Industrial Tile Drilling Solutions
Precision Dry Core Bits for Hard Porcelain & Natural Stone
DURO vacuum brazed diamond tile drills are engineered to overcome the challenges of modern tile installation. Built with ultra-thin kerf geometry and premium synthetic diamond grit, our core drills deliver rapid, clean, non-chipping hole drilling through Grade 5 hard porcelain, ceramic, quartz, marble, and granite without cracking delicate tile faces.
Technical Mastery
Designed for Maximum Speed & Extended Tool Life
Standard tile drills suffer from rapid heat build-up and diamond stripping. DURO solves this through advanced vacuum brazing technology, permanently fusing diamond grains onto the high-tensile steel core.
- Integrated Cooling Wax: Internal paraffin core melts under drilling heat to absorb thermal stress during waterless drilling.
- Chip-Free Edge Finish: Thin wall matrix ensures minimal material displacement, preventing surface blow-outs.
- Multiple Fitting Options: Available in M14 female thread (angle grinders), 1/4" quick-release hex shank, and straight cylindrical shanks.
- Extensive Diameter Range: Standard sizes from 5mm up to 120mm for pipe passages, anchors, and electrical outlets.

Frequently Asked Questions
Expert application and procurement insights for commercial buyers and professional tradespeople.
Yes. DURO vacuum brazed diamond tile drills feature integrated cooling wax cores or enhanced side ventilation slots, enabling rapid, chip-free dry drilling through Grade 5 hard porcelain, quartzite, and sintered stone.
DURO offers tile drills in M14 thread attachments for standard angle grinders, quick-change hex shanks for cordless impact drivers and drills, and standard straight shanks for conventional drill chucks.
Start drilling at a 45-degree angle to create an initial crescent groove, then gradually bring the drill perpendicular while maintaining a light orbital rocking motion. This allows air to circulate, removes dust, and keeps cutting temperatures low.
DURO supplies global importers and distributors with bulk packaging, retail-ready blister packs, private labeling (OEM), custom size manufacturing, and fast international freight support.
