Description

Product Overview

The Hordion Micro Drill Bit Set is engineered for the most demanding miniature drilling applications. Featuring twenty high‑speed steel (HSS) twist bits ranging from 0.3 mm to 1.6 mm, the collection provides a seamless gradient of sizes that cover virtually every micro‑drilling need. Each bit is forged from premium HSS, delivering exceptional hardness, heat resistance, and long‑term durability while resisting rust and corrosion even in humid workshop environments. The shank ends are thoughtfully rounded, eliminating the risk of accidental finger cuts during rapid bit changes—a safety feature that sets this set apart from standard micro bits. All twenty bits are housed in a sturdy, compartmentalized case with clearly labeled slots, allowing users to locate the exact size they need within seconds. The compact dimensions of the case (5.94 × 3.98 × 0.79 inches) and its lightweight design (2.47 oz) make it ideal for on‑the‑go professionals, hobbyists, and educators alike.

Usage

Designed for precision work, this micro drill bit set excels in a variety of specialized fields. Electronics technicians will appreciate the ability to drill clean, accurate holes in printed circuit boards (PCBs) for component placement and trace repair. Jewelers and watchmakers can rely on the ultra‑fine diameters to set diamonds, repair delicate chains, and work on intricate metal settings without causing damage to surrounding material. Artists creating resin sculptures or miniature models will find the bits perfect for carving fine details, creating texture, and drilling pilot holes for assembly. The ergonomic design and safety‑rounded shanks also make the set suitable for educational settings, where students learn the fundamentals of micro‑machining under supervised conditions. Whether you are a professional repairing high‑value electronics, a hobbyist building scale models, or a craftsman restoring vintage jewelry, the Hordion set provides the precision and reliability required for flawless results.

FAQ

What materials can these micro drill bits effectively drill?

The HSS construction allows the bits to drill through a variety of soft to medium‑hard materials, including printed circuit board laminates, soft metals such as copper and brass, plastics, resin, and even delicate gemstones when used with appropriate speed settings.

Are the bits compatible with standard rotary hand tools?

Yes, each bit features a standard 1/8‑inch shank that fits most rotary hand tools, micro‑drills, and Dremel‑style accessories. The rounded shank design also reduces the risk of slipping during bit changes.

How should I maintain the bits to ensure long‑term performance?

After each use, wipe the bits clean of debris and apply a light coat of oil to prevent corrosion. Store them in the supplied case when not in use, and avoid exposing them to extreme temperatures or moisture for extended periods.

Can I use these bits for high‑speed drilling applications?

While the bits are designed for precision work at moderate speeds, they can handle higher RPMs typical of micro‑drilling tools. It is recommended to stay within the manufacturer’s speed guidelines (generally up to 30,000 RPM) to avoid overheating and maintain cutting efficiency.

What is the warranty coverage for this drill bit set?

Hordion provides a one‑year limited warranty covering manufacturing defects. If a bit fails due to a material flaw within the warranty period, contact our support team for a replacement or refund.
