thread cutting
THE BEST TOOLS
FOR HIGH-aCHIEVERS.

Reliable and versatile – the ARNO thread-cutting system for all types of threads, pitches and dimensions from a core diameter of 3.2 mm.

Unsurpassed quality, process reliability and versatility – this is the promise behind the ARNO thread-cutting system. With typical ARNO quality right down to the last detail, you benefit from a long tool life and maximum precision. Whether an internal or external thread, trapezoidal or round thread, Whitworth or conical pipe thread – with the appropriate clamp holders, boring bars, indexable inserts and support plates, success is possible at the first attempt.

Tool holders

Standard design for all thread profiles / U-design for more stable indexable inserts / V-design for vertical indexable inserts

Available with or without through-tool coolant

Sizes from 8x8 to 50x50 mm

Suitable for every thread

Metric threads (ISO)

Metric partial profile threads (60°, 55°)

Unified ISO coarse threads (UN)

Whitworth pipe threads (BSW, BSP)

Conical pipe threads (BSPT)

Trapezoidal threads (DIN 103)

American trapezoidal threads (ACME)

Aerospace threads (UNJ)

Tapered (fine) pipe threads (NPT)

Armoured steel conduit threads (DIN 40430)

Round threads (DIN 405), custom-made

Support plates

Tool holder with helix angle λ = 1.5°

In case of deviations in the rising angle, a corresponding support plate must be selected

The tip height of the indexable insert remains the same regardless of the chosen support plate

Indexable inserts

Standard version with three edges for all thread profiles

MINI 3 with three edges for internal machining of small diameters from 9.3 mm

MINI 2 with two edges for internal machining of small diameters from 7.3 mm

U-design with three edges, particularly stable for threads with steep pitches

V-design with three edges, vertical arrangement for machining large profiles, for pitches of 6–10 mm and external machining behind the collar

SB design with three edges, sintered chip-breaker, TiAIN-coated (AI 100) for long-chipping materials

Boring bars

Shanks with Ø 8 mm to 40 mm

Standard design for all thread profiles / U-design for more stable indexable inserts / V-design for vertical indexable inserts / Mini 3 for Dmin from 9.3 mm / Mini 2 for Dmin from 7.3 mm

With or without through-tool coolant

Steel or solid carbide boring bars
