KKS UFB-3 MT3 Tang Boring & Facing Head
Description
Arriving late October 2025 for delivery – Pre-order now
Condition:
Used; presents beautifully. Hand-tested—feed and dial feel smooth with positive action. MT3 taper with tang is clean. The included 32 mm sleeve shows patina and may affect ultimate concentricity; fine for general use but consider re-polish/replace if you need tight runout. Sold as pictured.
Product use / description
Compact boring & facing head for precision boring, fine diameter setting, and facing/undercutting on milling machines and jig borers. The tanged MT3 shank suits spindles without drawbars—great for quill-feed down operations. The supplied 32 mm sleeve lets you hold the head in a collet chuck or other 32 mm bore tooling when needed.
