THREAD MILLING

D-Thread

The D-Thread family of inserts and tool holders were originally developed in order to enable the cutting of threads in deep parts. The multi-insert holders allow for improved productivity.

Features:

  • A wide range of threads supported (60°-based and 55°-based)
  • Both standard and U-type inserts available
  • Each insert and tool holder can be used for external and internal threads

Our range of D-Thread tools consists of the following lines:

Image

THREADING INSERTS (PARTIAL PROFILE)

Partial profile thread milling inserts, for use only with the D-Thread toolholders.

Features:

  • Three cutting edges on each insert (reduces tooling costs)

Carbide Grade:

PVD TiALN coated sub-micrograin grade for stainless steels and exotic materials, at medium to high cutting speeds (P20-P40, K20-K30)

THREADING INSERTS (PARTIAL PROFILE, U-TYPE)

U-Type partial profile thread milling inserts, for use with the D-Thread toolholders. These inserts differ from the standard ones by offering support for threads with larger pitches (made possible by the altered geometries).

Features:

  • Three cutting edges on each insert (reduces tooling costs)

Carbide Grade:

PVD TiALN coated sub-micrograin grade for stainless steels and exotic materials, at medium to high cutting speeds (P20-P40, K20-K30)

TOOL HOLDERS FOR STANDARD INSERTS

Tool holders for machining long threads using the standard, partial-profile D-Thread inserts. These tool holders have an internal coolant bore.

Features:

  • 3 inserts per holder
  • Holders allow for a long overhang

Note:

  • Not compatible with U-type D-Thread inserts

TOOL HOLDERS FOR U-TYPE INSERTS

Tool holders for machining long threads using the U-type, partial-profile D-Thread inserts. These tool holders have an internal coolant bore.

Features:

  • 1-4 inserts per holder
  • Holders allow for a long overhang

Notes:

  • Not compatible with standard D-Thread inserts
  • For SR0580M11U, the thread pitch is restricted to:
    10-9 TPI (60° / Internal), 12-10 TPI (60° / External), 12-9 TPI (55°)
  • For SR0810M11U, the thread pitch is restricted to:
    10-8 TPI (60° / Internal), 12-9 TPI (60° / External), 12-9 TPI (55°)

SHELL MILL HOLDERS

Shell mill tool holders for machining long threads using the U-type, partial-profile D-Thread inserts.

Features:

  • 5 inserts per holder

Notes:

  • Currently, only 16U-sized U-type inserts are supported
  • Not compatible with standard D-Thread inserts
