2. Craft & Performance
All drill bits of the Blue Exposed Grit Dry Diamond Drill 9PC Set are produced by high-temperature integral brazing technology, the core manufacturing craft that guarantees long service life and balanced stable dry cutting performance of the Blue Exposed Grit Dry Diamond Drill 9PC Set. The full exposed diamond grit layout on each cutting head of the Blue Exposed Grit Dry Diamond Drill 9PC Set forms open chip removal gaps, which can automatically discharge high-temperature stone powder generated during dry rotation and effectively avoid grit clogging and local overheating abrasion during long-hour continuous dry drilling. The blue anti-rust electrostatic coating on thickened 45# steel body of the Blue Exposed Grit Dry Diamond Drill 9PC Set isolates dust and corrosive stone powder residue, preventing surface oxidation even under long-term dry construction environments without water cooling. The seamless brazed fusion structure firmly locks exposed diamond grit to prevent partial grit shedding under high-speed rotation and continuous friction load. The solid thickened steel base resists bending and drilling deviation, generating smooth round holes and greatly reducing tile edge chipping risk during dry processing. The matched blue hex flat tip drill supports positioning and rapid penetration, significantly improving the scene adaptability of the Blue Exposed Grit Dry Diamond Drill 9PC Set for no-water construction projects.
Application
The multi-spec functional Blue Exposed Grit Dry Diamond Drill 9PC Set is an indispensable power tool accessory for tile installers, home maintenance workers, renovation contractors and DIY stone processing enthusiasts who often carry out no-water construction. The nine matched drill sizes equipped in the Blue Exposed Grit Dry Diamond Drill 9PC Set can drill precise neat holes on glazed ceramic tile, vitrified tile, marble, granite, quartz stone and artificial stone without continuous water cooling. At indoor renovation and wall hardware installation sites, workers rely on the Blue Exposed Grit Dry Diamond Drill 9PC Set to drill hanging piece fixing holes, small pipeline through-holes and switch bottom box holes on wall tile and stone slabs. The unified compact body design of each standard drill allows operation in narrow confined gaps, while the hex shank flat tip drill fits all mainstream cordless drills without extra conversion adapters. Whether residential indoor quick tile refitting, short-term outdoor hardware installation or temporary small-scale stone processing without water supply, the complete size combination of the Blue Exposed Grit Dry Diamond Drill 9PC Set satisfies all common dry hole-making requirements without purchasing separate single-size drill bits individually.

3. Blue Anti-Corrosion High-Durability Protective Coating: It combines blue rust-proof protective coating and exposed diamond cutting layer, balancing long-term dry construction anti-oxidation performance and lasting cutting efficiency.
4. Dual Shank Design for Wide Compatibility: Standard bits fit ordinary drill chucks, and the supporting 1/4" blue hex flat tip drill is plug-and-play with all standard cordless electric drills.
5. Thickened 45# Steel Integral Brazed Structure: It adopts heavy-duty solid 45# steel substrate with full high-temperature brazing, anti-twist and anti-grit-shedding under continuous high-speed dry drilling load.
6. Authorized Industrial Safety Certification: The full set passes CE & EN 13236 industrial safety certification, featuring low vibration during dry operation to lower cracking risk of brittle tile and stone materials.
FAQ
Q1: What materials can the Blue Exposed Grit Dry Diamond Drill 9PC Set process?
A1: It fits glazed tile, vitrified tile, marble, granite, quartz and artificial stone; it is not suitable for thick steel-reinforced concrete.
Q2: What power tools match this drill set?
A2: Standard drills suit ordinary electric drill chucks; the 6mm blue hex flat tip drill fits all 1/4" hex cordless drills, no extra conversion adapter needed.
Q3: Can this drill set work for long continuous dry drilling?
A3: Intermittent short dry drilling is recommended to reduce tool overheating; prolonged non-stop dry drilling will shorten its service life and increase tile cracking risk.
Q4: Can I customize the appearance and packaging of the Blue Exposed Grit Dry Diamond Drill 9PC Set for bulk orders?
A4: Yes. As the original manufacturer of this drill set, we provide full OEM & ODM customization including drill body color, private brand logo printing and personalized packaging for global hardware importers.
