Description
Condition
Used (Excellent Mechanical Condition / Partial New Old Stock).
This is a premium boring and facing kit in exceptional mechanical condition. The main boring head body shows some light cosmetic patina consistent with age, but it is structurally perfect, there are no signs of crashes or misuse. The slide moves smoothly, and the critical MT3 taper is clean, damage-free, and well-lubricated.
Kit Status: The original wooden/metal box shows its age, but the contents are a “time capsule.” Several accessories within the kit are still sealed in their factory protective wax coating, indicating they have never been used.
Product Overview
The KKS UFB-3 is not just a standard boring head; it is a Universal Boring and Facing Head. While standard heads only hold a boring bar at a fixed diameter to enlarge a hole, this “Facing” head features a mechanism that allows the tool slide to feed radially outward or inward while the spindle is rotating.
This capability allows you to perform complex operations that are usually impossible on a milling machine, such as:
- Facing the bottom of a blind hole.
- Grooving (cutting snap ring grooves inside a bore).
- Tapering (boring tapered holes).
- Turning outside diameters on small bosses.
The kit includes the Auto-Feed Arm (Stop Rod), which, when held stationary, engages the internal gearing to drive the slide. It comes complete with a handful of HSS (High-Speed Steel) cutting tools, making it ready to run immediately.
Brand Information
KKS is a highly regarded manufacturer of precision tooling (often associated with high-quality Japanese or Taiwanese production standards similar to Kuroda or Mizoguchi). These universal heads are complex pieces of engineering, built with hardened and ground gearing to ensure smooth radial feeding under load.
