KYOCERA 105-0625.400 Micro Drill Bit 0.0625″ Carbide 1/8″ Shank

Description

Product Overview

The KYOCERA 105-0625.400 series micro drill bit is engineered for high‑precision drilling in demanding industrial environments. Constructed from sub‑micron grain carbide, the tool offers exceptional hardness and wear resistance, ensuring a long service life even under continuous use. Its 0.0625″ cutting diameter, combined with a 130° cutting angle, provides a sharp, clean entry that minimizes material deformation and reduces the risk of burr formation. The 1/8″ shank diameter matches standard machine tool collets, delivering secure grip and minimizing run‑out during high‑speed operation. With a total length of 1‑1/2″ and a cutting length of 0.4000″, the bit balances reach and rigidity, making it suitable for deep‑hole drilling in thin‑walled components. The uncoated carbide tip maintains its geometry without the need for additional surface treatments, offering consistent performance across a wide range of metals, including stainless steel, aluminum alloys, and hardened steels. Designed for both CNC and manual drilling applications, this micro drill bit integrates seamlessly into existing production lines, delivering reliable results with minimal setup time.

Usage

Designed for precision tasks, this micro drill bit excels in printed circuit board (PCB) manufacturing, aerospace component fabrication, and automotive part machining. Its small cutting diameter allows for drilling tight‑tolerance holes in dense materials, while the 130° angle reduces thrust force, enabling faster feed rates without compromising accuracy. The tool is compatible with high‑speed steel (HSS) and carbide‑tipped drill presses, as well as CNC spindle units that support 1/8″ shank accessories. Operators can employ the bit for creating pilot holes, venting holes, and clearance holes in complex assemblies where space constraints demand a compact yet robust solution. The carbide construction tolerates temperatures generated during high‑speed drilling, making it suitable for continuous production runs. For best results, use appropriate cutting fluids to extend tool life and achieve smoother hole finishes. Whether you are a seasoned machinist or a production engineer, the KYOCERA micro drill bit provides the reliability needed for critical applications.

FAQ

What materials can this micro drill bit handle?

The bit is suitable for a wide range of metals, including stainless steel, aluminum alloys, brass, copper, and hardened steels. Its carbide construction also works well with plastics and composite materials when appropriate cutting speeds are used.

Do I need to use cutting fluid?

While the bit can operate dry for short runs, using a suitable cutting fluid or coolant extends tool life, reduces heat buildup, and improves hole finish, especially during high‑speed or deep‑hole drilling.

Is the bit compatible with CNC machines?

Yes, the 1/8″ shank is standard for most CNC spindle units and manual drill presses. Ensure the machine’s collet or chuck matches the shank size for optimal performance.

How do I maintain the sharpness of the carbide tip?

Maintain proper drilling parameters, avoid excessive feed rates, and regularly clean the bit to remove metal chips. If the tip becomes worn, replace the bit to ensure consistent hole quality.
