KOT-T-Slot Cutter

Recommended for milling T-slots and lateral grooves in carbon, alloy and prehardened steel parts.
The TiSiN-coated head has six straight flutes. Its reduced neck enters a pre-machined slot so the head can mill the widened lower section from the side to form the T-slot profile.
⌀4–12 mm; 35 sizes.

UCIL-UN Internal Thread Mill, 3× Thread Length

Recommended for UN coarse- and fine-pitch internal threads requiring longer thread lengths in carbon, alloy and prehardened steels.
Extended reach places the cutting head at deeper thread locations, while the reduced neck provides wall clearance. The three-flute cutter has a 15° helix and TiSiN coating.
⌀1.18–6.65 mm; 10 sizes.

UENE-2-Flute Long-Neck End Mill

For sidewall milling and stepped-floor machining at greater reach in carbon, alloy and prehardened steels.
Two flutes with a 30° helix and AlTiCrN coating are combined with a short cutting section and reduced neck, extending tool-tip access to local profiles that require clearance past an upper wall.
⌀1–8 mm; 88 sizes.

KAB-2-Flute Ball End Mill for Aluminum

• Recommended for 3D surfaces and internal radii on aluminum parts, including curved profiles and rounded transitions.
• The ball nose machines concave profiles and fillets, while the two-flute layout leaves space for chip evacuation during continuous contour passes.
• ⌀1–16 mm; 16 sizes.

UAB-2-Flute Ball End Mill for Aluminum

• Recommended for 3D contours and internal radii on aluminum parts, including curved profiles and fine-radius details.
• The 40° helix and two-flute chip space suit continuous contour passes in aluminum, while the ball nose machines internal fillets at profile transitions.
• ⌀0.6–16 mm; 19 sizes.

KOV-Equal-Angle Chamfer Cutter

• Recommended for milling sloped side edges and trimming edges on aluminum, copper and resin parts.
• The 90° included-angle geometry and reduced neck suit edge features close to an adjacent wall. The tool has four flutes, a 20° helix and a TiSiN coating.
• ⌀1–12 mm; 9 sizes.

UCI-UN Internal Spiral Thread Mill

Recommended for UN internal thread milling in carbon, alloy and prehardened steels, with coarse-, fine- and extra-fine-pitch options.
A pitch-specific, multi-row cutting section machines the internal thread by helical interpolation. The TiSiN-coated design has a 15° helix, with three or four flutes depending on size.
⌀4.8–20 mm; 24 sizes.

UZE-4-Flute End Mill for Stainless Steel

For side milling, slotting and face milling in stainless and prehardened steels.
Four flutes with a variable 40°/42° helix and ZrN coating also support plunge milling, allowing vertical entry followed by side milling or slotting where side access is restricted.
⌀1–16 mm; 26 sizes.

UPE-4-Flute Heavy-Duty End Mill, 45° Helix

Recommended for side milling, slotting and face milling in carbon, alloy and prehardened steels.
Four flutes with a 45° helix and an AlTiCrN coating are suited to continuous side-profile and groove milling, with the helical edges entering the cut progressively.
⌀3–20 mm; 21 sizes.

UCN-NPT Internal/External Thread Mill

For milling NPT tapered internal and external pipe threads in carbon, alloy and prehardened steels, including threaded fittings and connectors.
Multiple rows of NPT-profile teeth span several pitches along the cutting length for form milling at the specified thread pitch. The design uses 15° helical flutes and TiSiN coating.
⌀4.74–17.99 mm; 8 sizes.

UCNF-NPTF Internal/External Thread Mill

For milling NPTF tapered internal and external pipe threads in carbon, alloy and prehardened steels where the component specifies an NPTF thread form.
Multiple rows of NPTF-profile teeth span several pitches along the cutting length, providing a dedicated form-milling option for NPTF pipe threads. The design uses 15° helical flutes and TiSiN coating.
⌀4.74–17.99 mm; 8 sizes.

UPET-4-Flute Heavy-Duty End Mill, 35° Helix

For side milling, slotting and face milling of carbon, alloy and prehardened steel components.
Four flutes with a 35° helix and AlTiCrN coating combine peripheral edges for walls with square-end edges for flat floors, making this a practical choice for straight walls and stepped surfaces.
⌀3–20 mm; 13 sizes.
