What Is a Porcelain Tile Drill Bit?
A porcelain tile drill bit is a specialized drilling accessory designed for use with electric drills, a common power tool. These bits are compatible with standard models of power tools, including some multi-impact drivers with flat impact adjustment settings.
There are specific bits engineered for impact drivers and electric drills. For precise drilling tasks, lightweight, rotation-only electric drills are recommended.
The bits are made from extremely hard materials, often referred to as “Diamond Core Bit No XX,” reflecting their robust construction.
Usage of Porcelain Tile Drill Bits
Porcelain tile drill bits are primarily used for drilling into hard materials such as porcelain tiles, concrete, mortar, and marble. With the power of a rotary screwdriver or impact driver, they are ideal for drilling into stone materials used in building exteriors, wall tiles, and precast wall surfaces.
These bits are also available for DIY enthusiasts, suitable for working with stone and ceramics. They can be used on softer materials as well, making it economical to own various types with different specifications.
Principle of Porcelain Tile Drill Bit
The core of the porcelain tile drill bit is a cylindrical blade made of diamond or superalloy. Adhering to the principle that “Diamonds can only be drilled with diamonds,” the blade tip is crafted from ultra-hard gemstones or equivalent materials like tungsten or tool steel, and is polished for precision.
The bit’s surface is coated with titanium to enhance abrasion resistance, creating a durable, double-layered blade profile.
Higher-end models feature an attached water tank to reduce dust scattering and enhance convenience. The heavily-worn blade tip can be replaced, adding to the bit’s economic value.
There are also manual variants of these drill bits. These consist of a U-shaped hand-pushed rotating part with a grip, allowing the user to drill holes by pushing the spiral-grooved bit tip into the material.
