This multifunctional drill bit is specially designed to handle tough wall surfaces such as ceramic tile, concrete, brick, cement board, and natural stone. Its eccentric tip structure provides a stable starting point and minimizes surface cracking, making it ideal for precision drilling on delicate or dense materials.
Equipped with a sharp carbide or alloy steel tip and an optimized spiral flute, this drill bit offers clean chip removal, reduced friction, and accurate hole placement. The design minimizes edge chipping and is perfect for mounting hardware, anchor setting, or electrical installations on masonry and tile walls.
Made from industrial-grade alloy steel with a reinforced core, the bit is heat-treated for excellent hardness and wear resistance. It endures high torque and friction, ensuring a long service life, even in continuous or demanding use on reinforced walls.
Ideal for professionals and DIY users alike, this eccentric drill bit works across various substrates, including tiles, concrete blocks, cement plaster, red brick, and drywall. Its versatile design reduces tool changes, improves work efficiency, and ensures consistent performance across different wall drilling applications.
1. Sharp, Wear-Resistant HSS Cutting Edge
Forged from premium high-speed steel (HSS), this bit delivers exceptional hardness and red hardness, retaining its sharp edge even under high-speed, high-temperature drilling. Ideal for clean, efficient holes in tile, cement walls, red brick, and lightweight concrete-with minimal chipping.
2. Anti-Slip Eccentric Tip for Precise Entry
Featuring a dedicated eccentric tip design plus a finely ground pilot point, it prevents walking on smooth surfaces like glazed tile. You'll enjoy accurate, stable entry every time-perfect for high-precision tasks such as installing electrical boxes, hangers, or pipe clamps.
3. Optimized Spiral Flute for Smooth Chip Evacuation
The scientifically profiled spiral flute rapidly expels dust and debris, reducing heat buildup and preventing clogging. This means uninterrupted drilling-even during long jobs-and less wear on both the bit and your drill.
4. Corrosion-Resistant Finish for Long-Lasting Durability
A polished surface with anti-rust treatment ensures reliable performance in humid or dusty environments, such as kitchens, bathrooms, or outdoor projects where corrosion resistance is essential.
5. Lightweight, Ergonomic Design to Reduce Fatigue
Engineered for balance and comfort, the bit minimizes hand strain during extended use. Whether you're a tradesperson or a DIY enthusiast, enjoy excellent control and reduced fatigue on every job.
1. Superior HSS Performance
Compared to conventional carbon or alloy-steel bits, high-speed steel offers dramatically better wear resistance and heat tolerance-staying sharp and dependable even under repeated, demanding use.
2. Broad Compatibility Across Wall Materials
One bit handles tile, concrete, red brick, drywall, marble, and more. Perfect for plumbing, electrical work, wall mountings, and general renovation, it eliminates frequent bit changes and speeds up workflows.
3. Ideal for Pros and DIYers Alike
From contractors and electricians to plumbers and home-improvement hobbyists, this versatile eccentric bit delivers precise, reliable results on every hard-wall drilling task-making it the go-to tool for challenging surfaces.
1. CNC Precision-Ground Cutting Tip
Each eccentric drill bit is manufactured using CNC precision grinding, ensuring stable and accurate drilling on hard surfaces such as ceramic tile and concrete. The sharp cutting geometry and offset tip prevent slipping on smooth surfaces, enabling clean starts and reducing the risk of surface cracking.
2. Optimized Heat Treatment for HSS Core
Built from high-speed steel (HSS), the drill bit undergoes carefully controlled heat treatment to maximize hardness, edge retention, and resistance to deformation. It is ideal for repetitive drilling in masonry, cement walls, and brick structures.
3. Polished Spiral Flute for Efficient Chip Removal
The spiral flute features a refined polished finish that promotes smooth chip evacuation and reduces friction. This helps minimize heat buildup and prevents clogging, particularly when drilling into dense materials like tile grout or fiber cement boards.
1. High-Purity HSS Material
Manufactured through electric arc furnace (EAF) melting and vacuum degassing, the high-speed steel core delivers excellent toughness, wear resistance, and material purity, ensuring consistent performance even in abrasive masonry environments.
2. Balanced Structural Strength with Tough Core
Advanced quenching and tempering processes give the bit an ideal balance of surface hardness and core toughness, minimizing risks of breakage, edge chipping, or premature dulling-especially when working with reinforced concrete or solid brick walls.
1. Eccentric Tip for Accurate and Stable Entry
The uniquely offset cutting tip is specifically designed to reduce wandering on glazed tiles or uneven concrete, improving starting accuracy and reducing edge damage during installation work.
2. Optional Customization Available
We offer custom flute lengths, cutting geometries, and optional surface coatings such as TiN (titanium nitride) or TiAlN (titanium aluminum nitride). These coatings enhance tool life and cutting performance when drilling into abrasive or high-friction materials.
1. High-Efficiency Spiral Flute Design
This eccentric drill bit incorporates an optimized spiral flute structure that rapidly removes concrete dust, tile debris, and fine particles during drilling. The design minimizes clogging and heat buildup, ensuring smooth chip flow and efficient operation-even under prolonged use on dense, hard wall materials.
2. Precision-Engineered Cutting Angles for Hard Surfaces
The cutting edge and helix angles are specifically tailored to penetrate materials like ceramic tile, concrete, and brick with reduced resistance. These optimized geometries improve drilling accuracy and stability, while minimizing chipping, surface cracking, and material damage-especially on brittle or glazed surfaces.
3. Customizable Coatings for Harsh Conditions
To meet the demands of abrasive or high-friction applications, this drill bit supports advanced surface coatings such as:
- TiAlN: Excellent heat resistance for high-speed drilling
- TiCN: Superior wear resistance for extended tool life
These coatings help maintain sharpness and structural integrity during heavy-duty operations, significantly increasing durability and performance in demanding environments.
Q1: What distinguishes this eccentric drill bit from standard masonry bits?
A: This drill bit features a specially engineered eccentric tip that offers stable and precise starting, particularly on smooth, glazed, or brittle surfaces like ceramic tile. Unlike standard masonry bits, it combines this with a high-speed steel (HSS) core, delivering enhanced durability, edge retention, and impact resistance. This makes it ideal for challenging wall materials such as concrete, brick, tile, and cement panels.
Q2: What materials can this drill bit be used on?
A: This is a multifunctional bit designed to handle a variety of surfaces including ceramic tile, concrete, red brick, cement board, stone, drywall, and plaster. It's particularly suitable for professionals who need to switch between different wall types during installation, construction, or renovation tasks.
Q3: Are various sizes and specifications available?
A: Yes. We offer standard diameters ranging from 5mm to 14mm, with custom sizes available upon request. Length, flute design, and shank type (round, hex, or SDS) can also be tailored to match your specific tools and applications. OEM and ODM support is available.
Q4: Can this bit withstand high-speed or impact drilling operations?
A: Absolutely. The heat-treated HSS construction provides outstanding strength and thermal resistance, making it suitable for high-speed rotary drills and impact (hammer) drills. It resists wear, chipping, and overheating even during intensive, repeated use on masonry and tile walls.
