Description

Product Overview

The KYOCERA 105-1161.400 micro drill bit is a precision‑engineered tool designed for the most demanding drilling applications in metalworking, electronics, and prototype manufacturing. Constructed from sub‑micron grain carbide, the bit offers superior hardness, wear resistance, and thermal stability, allowing it to maintain a sharp cutting edge even under high‑speed operation. Its 130° cutting angle and two‑flute geometry provide optimal chip evacuation and reduced friction, resulting in smoother hole finishes and extended tool life.

Measuring a cutting diameter of 0.1161 inches and a cutting length of 0.4000 inches, this micro drill delivers exceptional accuracy for tiny apertures that are common in printed circuit board (PCB) drilling, micro‑machining, and fine‑detail metal fabrication. The 1/8 inch shank diameter ensures compatibility with standard collet systems, while the overall length of 1‑1/2 inches offers sufficient reach for deep‑hole drilling without compromising rigidity.

Designed for versatility, the bit can be used in a variety of CNC machines, manual drill presses, and handheld rotary tools. Its uncoated carbide surface reduces the risk of material buildup, making it ideal for drilling through hardened steels, aluminum alloys, brass, and composite materials. The precise tolerances and consistent geometry of the KYOCERA 105‑1161.400 series guarantee repeatable results across multiple production runs.

In addition to its technical specifications, the drill bit benefits from Kyocera’s reputation for quality and reliability. Each bit undergoes rigorous testing to meet strict industry standards, ensuring that users receive a product that performs consistently under demanding conditions. The compact packaging dimensions of 1.88 x 0.5 x 0.5 inches make storage and inventory management straightforward for workshops and manufacturing facilities.

For engineers and technicians who require exacting tolerances, the KYOCERA micro drill provides a balance of durability and precision that reduces downtime and tool changes. Its ability to produce clean, burr‑free holes minimizes the need for secondary finishing operations, thereby improving overall production efficiency. Whether you are fabricating intricate mechanical components or assembling delicate electronic devices, this drill bit delivers the performance you need.

Beyond its core capabilities, the bit’s design incorporates a balanced weight distribution that minimizes vibration during high‑speed drilling. This feature not only enhances user comfort but also contributes to the longevity of the tool by reducing wear on bearings and spindle motors. The two‑flute configuration is optimized for rapid chip removal, which is especially important when working with softer materials that tend to clog conventional drill geometries.

Kyocera’s commitment to sustainability is reflected in the manufacturing process of this micro drill. The carbide material is produced using environmentally responsible methods, and the uncoated finish eliminates the need for additional chemical treatments. This approach aligns with modern industry standards for eco‑friendly tooling while maintaining the high performance expected from a premium product.

Overall, the KYOCERA 105-1161.400 micro drill bit stands out as a reliable, high‑precision solution for professionals seeking consistent results in micro‑drilling applications. Its combination of advanced carbide technology, thoughtful geometry, and robust construction makes it a valuable addition to any toolset.

Usage

This micro drill is ideally suited for creating tiny holes in printed circuit boards, aerospace components, medical devices, and precision instrumentation. Its small cutting diameter enables the creation of vias and clearance holes that are essential for signal routing and component placement in densely packed electronic assemblies. The carbide material allows it to penetrate hardened steel and titanium alloys without losing sharpness, making it a versatile choice for both soft and hard substrates.

When used in CNC drilling operations, the bit’s consistent geometry ensures repeatable positioning and depth control, which is critical for high‑volume production environments. Operators can program the drill to achieve exact tolerances, reducing scrap rates and improving overall yield. In manual drilling scenarios, the ergonomic design of the shank provides a comfortable grip and stable rotation, allowing technicians to achieve precise results even in tight spaces.

For hobbyists and small‑scale manufacturers, the drill’s compact size and affordable price point make it an accessible tool for prototyping and custom projects. Whether you are fabricating a prototype enclosure, assembling a custom PCB, or working on a delicate metal sculpture, the KYOCERA micro drill delivers the accuracy and reliability needed to bring your ideas to life.

In high‑temperature environments, the carbide composition maintains its hardness, preventing deformation that could compromise hole quality. This makes the bit suitable for drilling in applications where heat buildup is a concern, such as high‑speed machining or when using lubricants that may raise operating temperatures.
