Description
Product Overview
The KYOCERA 226-1051L400 series micro drill bit is a precision‑engineered tool designed for the most demanding miniature drilling applications. Constructed from sub‑micron grain carbide, the bit offers superior hardness, wear resistance, and thermal stability, ensuring consistent performance even after extended use. Its 2.67 mm cutting diameter and 130° cutting angle provide a sharp, clean entry that minimizes burr formation and reduces the risk of material delamination, which is critical when working with printed circuit boards, micro‑electronics, and other delicate substrates. The 10.20 mm cutting length, combined with a 3 mm shank diameter, delivers excellent rigidity while maintaining a compact overall length of 38 mm, allowing the bit to reach into confined spaces and tight geometries. The two‑flute design optimizes chip evacuation, reducing heat buildup and extending tool life. Detailed specifications include a package size of 1.88 × 0.5 × 0.5 inches and a weight of just 0.19 oz, making it easy to store and handle. Since its introduction in February 2017, this model has earned a strong reputation, ranking #80 in the Micro Drill Bits category on Amazon and achieving a best‑sellers rank of #21,513 in the broader Drill Bits segment. Whether you are a professional technician, a hobbyist maker, or a manufacturing engineer, this drill bit delivers the reliability and precision required for high‑quality micro‑drilling tasks.
Usage
Designed for a wide range of micro‑drilling scenarios, the KYOCERA 226‑1051L400 excels in environments where accuracy and minimal material disruption are paramount. It is ideally suited for creating vias and mounting holes on printed circuit boards, drilling pilot holes in aerospace components, and fabricating intricate patterns in medical device housings. The bit’s carbide composition allows it to cut through hardened metals, alloys, and composite materials without dulling, making it a versatile choice for both prototyping and production runs. When paired with a high‑speed rotary tool or a CNC spindle, the bit maintains its geometry even at elevated RPMs, delivering consistent hole diameters and smooth wall finishes. Users should employ appropriate coolant or lubrication to further reduce heat and improve chip removal, especially when drilling into tougher substrates. The ergonomic shank design ensures a secure grip in collet or chuck systems, minimizing run‑out and vibration. This drill bit is also compatible with precision hand drills for field repairs or on‑site adjustments, providing flexibility across various workstations. Whether you are assembling delicate electronic modules, performing quality‑control testing, or conducting research and development on micro‑fabricated parts, this tool offers the reliability and performance needed to achieve professional results.

FAQ
What materials can this micro drill bit cut?
The bit is suitable for a variety of materials including printed circuit board laminates, hardened metals, alloys, composites, and delicate plastics. Its carbide tip maintains cutting performance across these substrates.
What is the recommended spindle speed for optimal performance?
For most PCB and electronic applications, a spindle speed between 15,000 and 30,000 RPM is ideal. When drilling harder metals, lower speeds around 8,000 to 12,000 RPM help prevent excessive heat.
How do I extend the life of the drill bit?
Use proper coolant or lubrication to reduce heat, ensure the bit is correctly seated in the chuck to avoid wobble, and periodically inspect the cutting edge for wear. Replacing worn bits promptly maintains hole quality.
Is this drill bit compatible with standard CNC machines?
Yes, the 3 mm shank fits standard collets and chucks used in most CNC milling and drilling machines. Its compact length also makes it suitable for high‑precision robotic drilling stations.
What warranty does Kyocera provide for this product?
Kyocera offers a limited warranty covering manufacturing defects for a period of one year from the date of purchase. Contact our support team for warranty claims or technical assistance.
