Micro Mini Drill Bit Set ZZHXSM 40pcs Fully Ground HSS 0.3-1.6mm

Description

Product Overview

The ZZHXSM 0.3‑1.6mm Micro Mini Drill Bit Set is engineered for precision work where size and accuracy matter most. Each of the 40 bits is fully ground from high‑speed steel (HSS), a material known for its hardness, heat resistance, and long‑lasting edge retention. The set covers a comprehensive range of diameters—from the ultra‑fine 0.3mm tip up to 1.6mm—allowing users to tackle delicate tasks such as PCB drilling, model making, and fine woodworking without sacrificing stability. The bits are supplied in two clear, snap‑fit plastic drawer cases, each holding 20 pieces, which protect the tips from damage and make selection quick and intuitive. With a total package weight of just 2.24 ounces and compact dimensions of 6.3 x 4.33 x 0.39 inches, the kit is portable enough to fit in a tool belt, a small toolbox, or a desktop organizer.

Usage

Designed for a wide variety of applications, this micro drill bit set excels in environments where space is limited and precision is critical. Hobbyists who build electronic prototypes will find the 0.3mm‑0.8mm bits ideal for creating clean vias and component holes on printed circuit boards. Woodworkers and model makers can rely on the 0.9mm‑1.6mm sizes to drill fine detail holes in hardwood, softwood, and engineered wood without splintering. The bits also perform well on plastics such as acrylic, polycarbonate, and PVC, making them suitable for DIY home‑repair projects like installing hardware in furniture or creating custom brackets. Because the bits are not intended for hard metals, they preserve their cutting edge when used on softer substrates, extending the life of the entire set.

FAQ

What materials can these micro drill bits safely drill?

The bits are optimized for wood, soft plastics, acrylic, circuit boards, and other non‑metallic substrates. They are not recommended for hard metals such as steel or titanium.

How do I choose the correct bit size for my project?

Match the required hole diameter to the bit size list provided in the packaging. The set includes sizes from 0.3mm up to 1.6mm, clearly labeled on each drawer case for quick reference.

Can I use these bits in a standard electric drill?

Yes, the bits feature a standard 0.3‑1.6mm shank that fits most miniature drill chucks and precision drill presses. For best results, use a low‑speed setting and apply steady pressure.

What should I do if a bit becomes dull?

Because the bits are made from high‑speed steel, they retain their edge longer than carbon steel alternatives. If a tip does dull, you can sharpen it with a fine diamond stone or contact our support for a replacement.

Is there a warranty on this drill bit set?

ZZHXSM offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues, contact our customer service for a replacement or refund.
