Product Description

Introducing the remarkable Precision Serrated Drill Bit for Heavy-duty Tile Drilling Applications with an advanced four-bladed serrated design.

Exterior Design

Four Blade Serrated Structure: Featuring four skillfully crafted cutting edges with serrated contours, this design not only expands the cutting surface but also adeptly minimizes friction. This innovative feature prevents overheating, enhancing both the speed and precision of your drilling endeavors.
Eccentric Design: Ingeniously engineered with non-coinciding center and axis lines, this drill bit generates substantial centrifugal force variation during rotation. This dynamic difference boosts rotational speed and precision, effectively diminishing shaking and offset for unparalleled accuracy in drilling.

Hexagonal Shank: Designed with a robust hexagonal shape, this shank guarantees a secure and firm fit with the chuck of various electric tools. It ensures steady clamping, reduces slippage, and enhances both the stability and precision of your drilling tasks.

Material Characteristics

High-Speed Steel Material: Boasting excellent toughness and wear resistance, this material endures impact loads and excels in drilling on materials with lower hardness, such as ordinary tiles and wood, delivering reliability and versatility.

Tungsten Steel Material: Renowned for its superior hardness and heat resistance, tungsten steel is perfect for dry casting on high-hardness materials like ceramic tiles, marble, and concrete, promising extended durability and longevity.

Performance Advantages

Efficient Drilling: The synergistic blend of a four-blade serrated design and eccentric engineering propels drilling speeds beyond conventional bits, enabling swift task completion and significantly boosting work efficiency.

• Precise Positioning: The alignment of eccentric design with a stable structure ensures meticulous precision in positioning, crafting smooth and perfectly rounded holes with minimal deviation, thereby enhancing construction outcomes.

Smooth Chip Removal: The serrated configuration facilitates seamless chip removal, ensuring debris is promptly evacuated during drilling. This prevents accumulation, maintaining high drilling efficiency and superior quality.

Wide Applicability: This versatile drill bit is adept for various materials across home decoration and construction projects, including tiles, glass, marble, concrete, wood, metal, and more, making it an indispensable tool for diverse applications.
