THREAD MILLING

Spiral Mill-Thread

The Spiral Mill-Thread family of indexable tools is a family of tools that use a spiral-based design. Each spiral-fluted tool holder contains anywhere between 1 and 9 inserts, in a comparatively small cutting diameter. This makes the tools well-suited for a wide range of applications: From machining minuscule components in small machining centers, to heavy-duty applications in high-power milling machines.

Features:

  • Spiral tools reduce vibration and chatter
  • High-quality finish is achieved in all applications
  • Tools allow for a smooth cutting operation at at high feed rates, reducing machining times
  • Unique clamping method enables optimal indexability

The following product lines can used for thread milling:

THREADING INSERTS

A product line containing threading inserts for popular thread profiles. Depending on the length of the insert, these tools can provide a solution for pitches from 1.0 mm / 16 TPI to 6.0 mm / 4 TPI.

Features:

  • The same insert can machine both internal & external applications (except for inserts for ISO and UN threads)

Carbide Grade(s):

Sub-micron grade with multi-layer TiAIN coating. This is a general purpose grade, which can be used with all materials. (ISO K10-K20)

TOOL HOLDERS

A product line of basic holders for the Spiral Mill-Thread family of tools. All holders in this line have internal coolant bore, allowing an efficient delivery of the cooling liquid to the cutting edges.

Features:

  • Multi (1-5) inserts per holder

Note:

  • SRH17-2 / SRH17J-2 / SR0670H17-2 / SR0670H17J-2: When using inserts for the conical threads (NPT / NPTF / BSPT), the cutting diameter (D) becomes 18 mm / 0.71 inch.

TOOL HOLDERS (WITHOUT NECKS)

Unlike the tools that belong to the line of basic Spiral Mill-Thread holders, the holders in this line use slightly different geometries, as they don’t have a “neck”. These holders are equipped with an internal coolant bore, enabling efficient removal of chips from the hole.

Features:

  • Multi (4-6) inserts per holder

SHELL MILL HOLDERS

A product line of shell mill holders with an internal coolant bore.

Features:

  • Multi (5-9) inserts per holder
