Core Craft of Plated Steel Blank Glass Drill Bits
Forging Process for Thickened Plated Steel Blank Base
Plated Steel Blank Glass Drill Bits adopt high-precision seamless steel tube as raw blank material, processed by CNC precision turning and high-temperature stress relief tempering. Compared with cheap thin-wall drill bits on the market, the base body of Plated Steel Blank Glass Drill Bits boasts 60% higher torsion and bending resistance. Large-size Plated Steel Blank Glass Drill Bits will not have shank distortion or cracking under long-term high-intensity drilling, extending the overall service life of tools and reducing frequent replacement costs of consumables.
High-Adhesion Vacuum Electroplated Diamond Technology
The head of Plated Steel Blank Glass Drill Bits applies closed-loop vacuum electroplating technology. High-strength synthetic diamond grains are evenly fixed on the working surface with deep embedding depth and strong bonding force, effectively preventing grain falling and rapid dullness during drilling. Under the same working conditions, the wear life of Plated Steel Blank Glass Drill Bits is 2-3 times longer than ordinary electroplated drill bits, maintaining stable cutting smoothness throughout the service cycle.
Tooth Anti-Slip Head Structural Design
The front end of Plated Steel Blank Glass Drill Bits features segmented serrated occlusion structure, which quickly bites the workpiece surface at the initial drilling stage to solve the slipping and deviation pain point on glossy glass & tile surfaces. Reserved chip removal gaps on the head discharge glass powder and stone debris with cooling water in time, avoiding abrasive blockage, overheating burnout of drill bits and edge chipping damage of workpieces.
Practical Performance of Plated Steel Blank Glass Drill Bits
Drilling Efficiency: With water cooling, the 6mm size Plated Steel Blank Glass Drill Bits only take 3-7 seconds to drill a hole on common float glass, realizing precise positioning without repeated correction;
Wear Resistance: After continuously drilling 200 standard tile boards, the diamond working layer has no obvious wear, keeping regular aperture without expansion deviation;
Workpiece Protection: The serrated positioning structure with uniform feed rarely causes edge chipping and cracking on glass, full-polished tiles and thin marble slabs, lowering the rejection rate of workpieces;
Safety Stability: Compliant with EN 13236 safety standard for power tool accessories, excellent concentricity during high-speed rotation without eccentric jump, reducing operation injury risks and workpiece damage.

5. Product Advantages
Advantage 1: Thickened Plated Steel Blank, Durable & Break-Resistant
Cheap glass drill bits on the market adopt inferior thin-wall blanks, easy to break with slight inclined drilling. Plated Steel Blank Glass Drill Bits feature thickened tempered steel blank structure with strong torsion & bending resistance. Even minor inclined feed from novice misoperation will not cause shank breakage, cutting long-term consumable procurement costs.
Advantage 2: Vacuum Electroplated Diamond, Sharp & Grain-Fall Resistant
Ordinary electroplated drill bits with rough plating process suffer massive grain falling after dozens of uses and get scrapped quickly. Plated Steel Blank Glass Drill Bits use vacuum electroplating technology to firmly lock diamond grains, maintaining stable sharpness throughout the service cycle and drastically reducing replacement frequency under the same usage intensity.
Advantage 3: Full Size Coverage, One-Stop Demand Matching
Plated Steel Blank Glass Drill Bits include 21 mainstream hole sizes from 6mm small positioning holes to 60mm large pipeline holes. Home purchasers and cross-border sellers do not need to place separate orders for multiple drill models, simplifying inventory management and meeting personalized aperture demands of diverse customers.
Advantage 4: Multi-Spec Shank Design, Wide Compatibility with Power Tools
6mm standard straight shank for small sizes fits 99% mainstream household electric drills globally; upgraded 9/10mm thickened shank for sizes above 18mm adapts to high-power industrial drills. Custom M14 thread shank is also available for direct assembly with angle grinders for heavy-duty work, expanding applicable scenarios greatly.
Advantage 5: Authoritative Safety Certifications, Global Market Compliance
Every batch of Plated Steel Blank Glass Drill Bits passes CE certification and EN 13236 EU power tool safety standard test. Fully compliant product qualifications allow cross-border sales to mainstream markets including Europe, America and Southeast Asia without extra compliance audit risks for foreign distributors.
Advantage 6: Anti-Chipping & Chip Removal Design, Lower Workpiece Rejection Rate
The dual design of serrated positioning head and chip removal slots on Plated Steel Blank Glass Drill Bits eliminates slipping & deviation issues on glossy materials. Cooling water paired with chip removal structure quickly dissipates heat and debris, minimizing edge chipping & cracking during glass and tile drilling and reducing raw material loss costs for processing users.

8. FAQ
Q1: What materials can Plated Steel Blank Glass Drill Bits drill?
A1: Plated Steel Blank Glass Drill Bits are ideal for float glass, thin tempered glass, glazed tiles, vitrified tiles, marble, travertine, crystal, jade and other brittle hard materials. We do not recommend drilling fully tempered safety glass thicker than 8mm to avoid spontaneous glass explosion.
Q2: Is water cooling required when using Plated Steel Blank Glass Drill Bits?
A2: Yes, continuous water cooling is mandatory. When operating Plated Steel Blank Glass Drill Bits, keep pouring clean water on the drilling position to reduce high-temperature friction burnout of the diamond layer, prevent glass cracking caused by thermal expansion & contraction and extend the service life of drill bits.
Q3: What power tools match Plated Steel Blank Glass Drill Bits?
A3: The standard 6mm straight shank of Plated Steel Blank Glass Drill Bits fits most 10mm/13mm chuck household electric drills. If you need to use angle grinders, select the optional M14 thread shank version of Plated Steel Blank Glass Drill Bits for direct assembly.
Q4: Why does the drill bit slip at the initial drilling stage of Plated Steel Blank Glass Drill Bits?
A4: Our Plated Steel Blank Glass Drill Bits are designed with anti-slip serrations on the top. If slipping occurs, tilt the drill bit by 15° to scratch a positioning groove on the glass surface first, then adjust the drill bit vertical and drill at low speed to completely solve the slipping problem.
Q5: What is the lead time for bulk orders of Plated Steel Blank Glass Drill Bits?
A5: For in-stock Plated Steel Blank Glass Drill Bits, we arrange delivery within 3 working days. For customized packaging, logo and special shank demands, the production lead time ranges from 7-15 working days based on order quantity. Changshunda factory has stable production capacity to guarantee on-time delivery.
Q6: How to maintain Plated Steel Blank Glass Drill Bits after use?
A6: After using Plated Steel Blank Glass Drill Bits, rinse the drill head with clean water to remove residual glass powder and sediment, dry it and store in a dry tool box. Avoid long-term damp placement which may cause shank rust and declined diamond layer bonding force.
Q7: Do Plated Steel Blank Glass Drill Bits support third-party quality inspection?
A7: Yes, all batches of Plated Steel Blank Glass Drill Bits support authorized third-party laboratory inspection against CE and EN13236 standards. We can provide factory test reports and certification documents to cooperate with customers’ inspection requirements.
