Overview
Thread Mill M2.5 x 0.45 mm With Rainbow Coating Single Tooth Shank 4 mm Sintered Carbide Silver Shank CNC Milling Machines Threads M2.5

The thread mill M2.5 x 0.45 mm with rainbow coating has a single tooth with a thread profile and is used on CNC milling machines and machining centres. The tool body is made of sintered carbide, a hard material commonly used for manufacturing precise cutting tools. The coloured coating covers the cutting head and neck, while the clamping shank is silver. The thread is formed gradually as the machine guides the mill along the helix according to the programme. The tool is clamped by a cylindrical shank with a diameter of 4 mm.

  • Rainbow Surface Layer — the coating is visible in transitions of pink, purple, gold, and blue colours in the image. The type of coating is not specified by the supplier.
  • Size M2.5 x 0.45 mm — the mill is designed for a metric thread with a nominal diameter of 2.5 mm and a pitch of 0.45 mm, which is the standard coarse pitch for M2.5. M2.5 threads are used, for example, in small screws in electronics, devices, or small mechanisms.
  • Profile with a Tooth at the End — the cutting head carries a single row of the thread profile and a groove for chip removal is visible in the image. The thread is formed gradually, and its length can be set in the programme.
  • Path Around the Thread Axis — the mill rotates around the thread axis and moves vertically by 0.45 mm with each revolution. This movement is called helical interpolation, and the machine must support it.
  • Hard Carbide Material — the tool body is made of sintered carbide, which is harder than tool steel and retains the precise shape of the small tooth well.
  • 4 mm Uncoated Shank — the silver cylindrical shank is clamped into a collet or holder for a diameter of 4 mm. The thin neck allows the cutting head to enter the hole.
  • Direction of Helix in the Programme — a right or left thread is created depending on the direction the programme guides the tool. One mill can thus be used for both directions of the M2.5 x 0.45 mm thread.
  • Pre-drilling Before Milling — the internal thread is milled into a pre-drilled hole. Determine its diameter according to the tables for thread M2.5 and clean the hole of chips and burrs before milling.
  • Protection of the Cutting Edge — the cutting head is small and may break under overload. Choose appropriate feeds and speeds, and ensure firm and precise clamping. Store the mill in a case when not in use to prevent damage to the tooth or coating.
  • Package Contents — 1x single tooth thread mill M2.5 x 0.45 mm with rainbow coating and 4 mm shank.

The mill for thread M2.5 x 0.45 mm is used for producing small metric threads on CNC milling machines and machining centres. Sintered carbide provides the hardness needed for precise machining. The cutting head with rainbow coating has a single tooth, allowing the thread to be formed gradually, with its length and direction controlled by the programme. The mill is inserted into the holder by the silver 4 mm shank. It finds application in workshops and production where M2.5 threads need to be milled.
