Micro Drill Bits Daewon 10 Mixed Sizes 0.1-0.3mm CNC PCB Toy Jewelry

Description

Product Overview

Daewon Industries presents a meticulously engineered set of ten micro drill bits designed for the most demanding precision applications. Each bit is forged from Japanese‑sourced tungsten carbide, a material renowned for its superior hardness, heat resistance, and longevity. The set covers a comprehensive range of diameters—0.1 mm, 0.15 mm, 0.20 mm, 0.25 mm, and 0.30 mm—providing the flexibility required for intricate CNC machining, printed circuit board (PCB) prototyping, fine jewelry creation, and miniature toy assembly. The shank of every bit measures 1/8″ (3.175 mm), ensuring compatibility with a wide variety of standard power drills and CNC spindles. Packaged in a durable, reusable plastic case, the bits remain protected from contamination and mechanical damage, extending their service life even under heavy daily use.

Usage

These micro drill bits excel in environments where accuracy and repeatability are paramount. In PCB manufacturing, the sub‑millimeter diameters enable clean, burr‑free holes for component leads, vias, and micro‑connectors, reducing the need for post‑drilling cleanup. Jewelers appreciate the fine tolerances for setting delicate stones, engraving intricate patterns, and creating custom settings that demand flawless precision. Hobbyists and model makers find the bits indispensable for constructing miniature mechanical parts, assembling detailed toy components, and performing delicate installations in confined spaces where larger tools cannot reach. The bits are also suitable for aerospace and automotive prototyping, where tiny fasteners and sensor housings require exact hole dimensions.

FAQ

What material are the drill bits made from?

The bits are made from high‑grade Japanese tungsten carbide, which provides superior hardness, wear resistance, and heat tolerance compared with standard steel bits.

Can these bits be used in a CNC machine?

Yes, the 1/8″ shank is compatible with most CNC spindle holders, and the precise diameters are ideal for high‑resolution PCB routing and micro‑fabrication tasks.

How should I maintain the bits to ensure long life?

After each use, clean the bits with compressed air or a soft brush to remove debris, store them in the supplied case, and avoid drilling into hardened materials that exceed the recommended speed settings.

Are the bits suitable for jewelry making?

Absolutely. Their fine diameters and sharp carbide tips allow jewelers to drill precise holes for stone settings, create intricate patterns, and work with delicate metals without causing damage.
