This multifunctional drill bit is specially engineered to tackle tough materials like ceramic tile, concrete, brick, and stone. Its eccentric tip design allows for stable entry and reduces surface cracking, making it ideal for precision drilling in demanding conditions.
Featuring a sharp carbide tip and spiral flute design, the bit ensures smooth debris removal and accurate hole placement with minimal chipping. It's perfect for wall-mounted installations, electrical boxes, or anchor setting in tiles and masonry walls.
Crafted from industrial-grade alloy steel with a reinforced core, this drill bit withstands high torque and friction. The heat-treated body resists bending and wear, providing extended tool life even under continuous heavy-duty use.
Ideal for plumbers, electricians, contractors, and DIYers, this eccentric drill bit adapts well to a variety of materials-tile, cement wall, concrete block, and drywall. Its multifunctional design reduces tool changes and ensures consistent performance across different jobs.
Crafted from premium high-speed steel (HSS), this drill bit delivers outstanding hardness and red hardness, maintaining sharpness even under high-speed and high-temperature drilling. Perfect for clean and efficient drilling in tile, cement walls, red brick, and lightweight concrete, with minimal chipping.
The specialized eccentric tip, combined with a finely ground point, helps prevent slippage on smooth tile surfaces. It ensures accurate starting and stable drilling-ideal for applications requiring precise positioning, such as installing electrical boxes, hangers, or pipe fasteners.
Designed with an efficient spiral flute structure, the bit smoothly ejects dust and debris during drilling. This helps reduce heat buildup and prevents clogging, supporting continuous operation and extending the tool's service life.
The polished and anti-rust-treated surface enhances durability in humid or dusty environments. Suitable for construction tasks in bathrooms, kitchens, or outdoor settings where corrosion resistance is essential.
Lightweight and evenly balanced, the drill bit minimizes hand fatigue during extended use. Its user-friendly design ensures excellent control and maneuverability, making it suitable for both professionals and DIY users.
Compared to regular carbon or alloy steel, HSS offers superior wear resistance and heat resistance-ideal for demanding high-speed drilling tasks. It stays sharp and durable even when used repeatedly on tough wall materials.
This drill bit works seamlessly on ceramic tile, concrete, red brick, drywall, marble, and more. It's perfect for plumbing, electrical installation, wall mountings, and general renovation needs.
Whether you're a professional contractor or a home improvement enthusiast, this multifunctional HSS drill bit provides reliable and precise performance for various wall drilling tasks-making it a truly versatile drilling solution.
Each eccentric drill bit features a CNC precision-ground cutting tip, designed to deliver stable and accurate drilling in hard surfaces like ceramic tile and concrete. The sharp geometry and eccentric point reduce walking on smooth surfaces, ensuring precise entry and reduced surface cracking.
Constructed from high-speed steel (HSS), the drill bit undergoes controlled heat treatment processes to maximize hardness, edge retention, and resistance to deformation. Ideal for repetitive drilling in masonry, cement, and brick walls.
A finely polished spiral flute enhances chip evacuation and minimizes friction during drilling. This helps reduce heat buildup and prevents bit seizure, especially in dense materials like tile grout or composite wall panels.
Manufactured using electric arc furnace (EAF) melting and vacuum degassing, the high-speed steel base offers exceptional toughness, wear resistance, and structural purity. This ensures consistent performance even when drilling through abrasive masonry materials.
Quenching and tempering treatments provide the drill bit with optimal hardness and core toughness-reducing risks of breakage, chipping, or premature dulling when working on tough substrates such as reinforced concrete and brick.
The uniquely engineered eccentric tip is tailored to reduce walking on glazed tile or uneven concrete surfaces. This design improves start-point accuracy and minimizes damage to the surrounding area.
Custom flute lengths, cutting angles, or specialized coatings (e.g., TiN, TiAlN) can be applied based on user needs. Coated options are ideal for prolonging tool life when drilling into abrasive, high-friction materials.
The drill bit features an optimized spiral flute structure that enables fast removal of concrete dust and tile debris. This design helps prevent clogging and heat buildup, ensuring smooth and efficient drilling even during extended use on hard wall materials.
The cutting and helix angles are precisely engineered to enhance penetration into hard materials such as ceramic tile, concrete, and brick. These optimized angles reduce drilling resistance, improve entry stability, and minimize chipping or surface cracking.
Compatible with advanced surface coatings like TiAlN (for heat resistance) and TiCN (for enhanced wear resistance), this drill bit can be customized for demanding drilling environments. These coatings help maintain sharpness under high temperatures and heavy loads, significantly extending tool life.
Q1: What makes this eccentric drill bit different from standard masonry bits?
A: This drill bit features a unique eccentric tip design for stable, accurate starting, especially on smooth or glazed surfaces like ceramic tile. Combined with a high-speed steel (HSS) core, it offers superior durability, edge retention, and impact resistance compared to standard bits-making it ideal for drilling into tough wall materials.
Q2: What materials can this drill bit be used on?
A: This multifunctional bit is engineered to drill through ceramic tile, concrete, brick, cement board, and stone surfaces. It is also suitable for drywall or plaster when switching between different wall types on a job site-offering wide versatility in construction and renovation tasks.
Q3: Are different sizes available?
A: Yes. We offer this eccentric drill bit in a variety of standard diameters (e.g., 5mm to 14mm), with custom size options available upon request. Length and shank type (round or hex) can also be customized to fit specific tools and applications.
Q4: Can this drill bit handle high-speed or impact drilling?
A: Absolutely. The HSS body is heat-treated for strength and durability, allowing it to perform under high-speed rotary tools or hammer drills. It resists wear, overheating, and chipping during intensive drilling in masonry or tile walls.
