Description
KKS UFB-3 MT3 / C32 Universal Facing & Boring Head — Full Kit
A complete, working boring head kit from KKS — a name well regarded in European precision tooling — the UFB-3 is a universal facing and boring head built for toolroom-grade hole finishing, facing operations, and fine boring on mills and machining centres. This example ships as a full kit in its original wooden case, with the MT3 arbor, a removable 32 mm parallel sleeve for larger spindle tapers, a selection of boring bars, insert holders, collets, a countersink, drill, and all associated tooling. If you’ve been running a Morse taper mill or a machine with a 32 mm spindle bore and want a capable, adjustable boring head without paying new prices, this is a hard set to walk past.
- Micrometer-style cross-slide adjustment with engraved scale — The UFB-3 head features a graduated adjustment slide with clearly engraved markings, allowing repeatable radial tool offset in fine increments. This matters when you’re sneaking up on a final bore diameter in thou rather than chasing it with roughing cuts — you dial in the offset, take the finish pass, and hit the number.
- MT3 shank with removable C32 parallel sleeve — The Morse Taper 3 arbor seats directly into any MT3 spindle with no adapter required, giving a solid, self-holding taper connection ideal for knee mills and manual machining centres. The removable 32 mm parallel sleeve opens the head up to machines with a 32 mm (ISO 32) spindle bore, making this a genuinely dual-purpose unit that covers two of the most common light-mill spindle standards.
- Full accessory complement — boring bars, insert holders, collets, countersink, and drill — Visible in the kit are multiple boring bars of varying reach, what appear to be carbide insert boring holders, a set of collets (ER-style, stepped-bore type), a countersink, a twist drill, Allen keys for setup, and a fine adjustment pin tool. A complete kit like this gets you boring, spot facing, and countersinking from one box without sourcing individual accessories.
- Original wooden case, papers, and accessories — The dovetail-fitted hardwood case keeps every component located and protected. Having the original documentation means you’re not guessing at cross-slide pitch, offset range, or compatible bar shank sizes — the specs are there in front of you.
- Ideal for finishing bored holes to close tolerance on a knee mill or Bridgeport-style machine; facing bosses and step-bored housings; single-point boring bearing fits and housing bores; countersinking and spot facing on manual mills; toolroom setups where a boring head is used intermittently and storage matters.
Condition
Used (Good Condition / Full Working Kit, Original Box)
The boring head body presents with the expected patina of a used toolroom instrument — there is light surface wear consistent with workshop handling, and minor marks on the case exterior — but the precision surfaces tell the real story. The cross-slide dovetail moves smoothly with no detectable slop or binding, the graduated scale is legible, and the locking screws engage cleanly. The MT3 taper shank shows no visible dings or raised burrs that would compromise seating in the spindle. The C32 sleeve fits and removes as intended. The boring bars and insert holders show use but no chipping, cracking, or deformation to the shank diameters that would affect concentricity in the head. All components are present and housed in their correct locations in the original fitted case. Before first use, it is recommended practice to verify the head’s offset accuracy against a known bore or ring gauge, and to stone any minor handling marks from bar shanks before seating — standard procedure for any used boring tooling entering a new shop.
