Description
Product Overview
The KKS Kuroda UFB-3 is a masterclass in Japanese toolmaking. This is not a standard, static boring head; it is a true Universal Boring and Facing Head, designed to bring lathe-like turning capabilities directly to your milling machine spindle.
- Automatic Radial Feed: The defining feature of a universal head is its internal gearing. By engaging the feed mechanism and holding the stop ring, the tool block automatically feeds outward radially while the spindle turns. This allows you to machine flat faces, internal/external snap ring grooves, and complex undercuts with a single setup.
- MT3 Shank: This unit is equipped with a versatile Morse Taper 3 (MT3) integral shank, making it a perfect fit for a wide variety of milling machines, radial arm drills, and horizontal borers.
- Micro-Adjustable Accuracy: For standard boring operations, the micrometer dial provides ultra-fine adjustability, allowing you to dial in bearing fits and tight-tolerance bores with absolute confidence.
- Japanese Rigidity: Built to rival the legendary European Wohlhaupter heads, the Kuroda UFB series is prized for its hardened internal components, buttery-smooth dovetail slide, and ability to take heavy cuts without introducing chatter.
Condition
Used (Very Good Condition / Bare Tool).
This high-end universal boring head is in very good used condition. It has been well cared for in a professional environment and shows only minor visual signs of standard shop use.
- Mechanical Integrity: The dovetail slide is tight and smooth, the micrometer dial turns precisely, and the auto-feed engagement mechanism functions as it should.
- Important Note: This listing is for the bare tool only. It does not include the original storage box, boring bars, or the external stop rod/block (though a standard rod can easily be adapted for your specific machine to hold the ring during auto-facing).
