Designed for Hard Material Drilling
This eccentric drill bit is made from premium high-speed steel (HSS), specifically engineered for drilling through tough surfaces such as ceramic tile, concrete, and brick. The unique off-center tip design ensures stable entry, reduces bit slippage, and minimizes surface cracking-perfect for precision drilling on delicate materials like glazed tile.
Clean and Accurate Drilling
Equipped with a sharp HSS tip and spiral flute design, the bit offers fast, clean drilling with minimal edge chipping. It ensures efficient dust removal and precise hole placement, making it ideal for installing wall anchors, electrical boxes, plumbing components, and more.
Durable High-Speed Steel Construction
Crafted from industrial-grade HSS, the bit features excellent wear resistance, hardness, and heat resistance. It performs reliably under continuous high-torque applications without bending or premature dulling, greatly extending tool life.
Versatile for Multiple Applications
Suitable for plumbers, electricians, construction workers, and DIY users, this eccentric drill bit works efficiently on tile, cement walls, concrete blocks, and drywall. Its multifunctional design reduces the need for frequent tool changes and ensures stable performance across a variety of job sites.
1. Sharp and Wear-Resistant HSS Cutting Tip
Made from premium high-speed steel (HSS), the drill bit features excellent hardness and heat resistance. It maintains sharpness during high-speed operations, ensuring smooth, clean drilling through ceramic tile, cement walls, red brick, and lightweight concrete-all with minimal edge chipping.
2. Anti-Slip Eccentric Tip for Accurate Positioning
The uniquely engineered eccentric tip prevents walking or slipping on smooth surfaces like glazed tiles. Combined with a precision-ground point, it ensures stable starting and accurate hole placement-ideal for applications such as electrical boxes, fasteners, and wall anchors.
3. Efficient Spiral Flute for Quick Debris Ejection
The optimized spiral groove enhances chip removal and reduces heat buildup during continuous use. This prevents clogging and allows for smoother operation, helping to prolong the life of both the drill bit and the drilling equipment.
4. Corrosion-Resistant Surface Coating
The drill bit is finished with a polished, anti-rust treatment that withstands moisture and dust, making it highly suitable for bathrooms, kitchens, and outdoor construction environments.
5. Ergonomic, Well-Balanced Design
Lightweight and evenly distributed in mass, the bit offers better control and reduced hand fatigue during long drilling tasks. It's engineered for user comfort and consistent handling by both professionals and DIY users.
1. Superior Performance with HSS Material
Unlike conventional carbon or alloy steel bits, HSS offers significantly higher wear and heat resistance. It delivers consistent sharpness and durability when drilling into hard wall materials, even under repeated heavy use.
2. Wide Compatibility with Wall Materials
This drill bit is suitable for multiple materials including ceramic tile, concrete, red brick, drywall, marble, and more. One bit meets the needs of various renovation and installation jobs without frequent tool changes.
3. Trusted by Professionals and DIYers
Whether you're a contractor, electrician, plumber, or a DIY hobbyist, this drill bit is engineered to provide reliable, precise results for all types of wall drilling applications-making it your go-to solution for challenging materials.
1. CNC Precision-Ground Eccentric Tip
Each drill bit is crafted with a CNC-machined, eccentric cutting tip to ensure precise entry and stability when drilling into ceramic tile, concrete, and other dense materials. The sharp edge geometry minimizes walking on smooth surfaces and reduces surface cracking.
2. Optimized HSS Core with Heat Treatment
Constructed from high-speed steel (HSS), the bit undergoes advanced quenching and tempering processes to enhance hardness, edge durability, and resistance to deformation-ideal for repetitive use on masonry, cement, and brick walls.
3. Polished Spiral Flute for Smooth Chip Removal
The flute surface is finely polished to reduce friction and improve chip evacuation. This design minimizes heat buildup and prevents jamming, especially when drilling through tile grout or composite surfaces.
1. High-Purity HSS Composition
Manufactured through electric arc furnace (EAF) smelting and vacuum degassing, the high-speed steel offers excellent wear resistance, toughness, and structural integrity-ensuring consistent performance even on abrasive masonry.
2. Balanced Hardness and Core Strength
Special thermal treatments deliver an ideal combination of hardness and core ductility. This prevents premature dulling, chipping, or breakage when used on reinforced concrete or brick substrates.
1. Eccentric Tip for Controlled and Stable Entry
The unique offset-point design improves drilling accuracy on glazed tile and rough concrete, helping reduce surface damage and improve alignment during installation.
2. Optional Customization Available
Flute length, cutting geometry, and wear-resistant coatings (such as TiN or TiAlN) can be customized to meet specific application requirements. Coated options are ideal for prolonging tool life in high-friction or abrasive environments.
1. High-Efficiency Spiral Flute Design
Engineered with an optimized spiral flute, this drill bit enables rapid evacuation of dust and debris generated when drilling through tile and concrete. The design reduces clogging and heat accumulation, allowing for smoother, uninterrupted drilling in dense wall materials-even during extended operation.
2. Precision Cutting Angles for Hard Wall Penetration
The cutting edge and helix angles are specifically tailored for materials like ceramic tile, brick, and concrete. These refined geometries reduce resistance during drilling, improve entry stability, and help minimize edge chipping or surface cracks-ensuring cleaner holes and better installation quality.
3. Customizable Surface Coatings for Harsh Conditions
To adapt to demanding drilling tasks, the bit supports advanced surface coatings such as TiAlN for superior heat resistance or TiCN for enhanced wear resistance. These coatings preserve edge sharpness under heavy load and high-temperature conditions, significantly extending tool life in abrasive environments.
Q1: What sets this eccentric drill bit apart from standard masonry bits?
A: This drill bit features a specially engineered eccentric tip that delivers stable and accurate entry, especially on smooth or glazed surfaces like ceramic tile. Unlike conventional masonry bits, it combines this unique design with a high-speed steel (HSS) core, offering significantly better durability, edge retention, and impact resistance-making it highly effective for tough wall materials such as tile, concrete, and brick.
Q2: What materials is this drill bit suitable for?
A: This is a multifunctional drill bit designed for a wide range of wall materials, including ceramic tile, concrete, red brick, cement board, stone, plaster, and drywall. Its versatility allows professionals to switch between different wall types without changing tools-ideal for construction, renovation, and installation tasks.
Q3: Are multiple sizes and configurations available?
A: Yes. The drill bit is available in standard diameters ranging from 5mm to 14mm, with custom sizes, lengths, and shank types (round or hex) available on request. We also support OEM/ODM services to match specific tool compatibility and application needs.
Q4: Is it suitable for high-speed or hammer drilling?
A: Absolutely. The HSS body is heat-treated to withstand high-speed rotation and impact drilling, making it compatible with rotary drills and hammer drills. It resists wear, chipping, and overheating, even under prolonged use in dense masonry or tile surfaces.
