Overview
Coated Thread Mill M1 x 0.25 mm Single Flute Shank 4 mm Sintered Carbide Rainbow Coating and Silver Shank CNC Thread Milling M1

The coated single flute thread mill is designed for milling metric threads M1 x 0.25 mm on CNC milling machines and machining centres. The tool is made of sintered carbide and its cutting part and neck have a colourful coating with a rainbow sheen. The thread is not created by a tap but by milling along a helix, which is controlled by the machine's programme. The cutting head is at the end of the tool, followed by a thin neck and a silver cylindrical shank with a diameter of 4 mm. The mill is suitable for very small threads that require precise tool guidance.

  • Colourful Coating — as seen in the image, the cutting head and neck have a rainbow coating in shades of pink, purple, and blue, while the shank remains silver. The type of coating is not specified by the supplier.
  • Very Fine M1 Thread — the mill is intended for a metric thread with a nominal diameter of 1 mm and a pitch of 0.25 mm. Such threads are used, for example, in miniature screws in precision mechanics, electronics, or modelling.
  • Single Flute Cutting Head — the head carries a single row of thread profile and the image shows a groove for chip removal. The thread is formed gradually and its length is determined by the programme.
  • Helical Control — the mill revolves around the thread axis and advances by a pitch of 0.25 mm with each revolution. This movement is called helical interpolation and must be supported by the machine.
  • Carbide Base — the body of the tool is made of sintered carbide, which is harder than tool steel. The coating is applied to the cutting parts and neck.
  • Silver Shank 4 mm — the cylindrical shank without coating is clamped into a collet or holder for a diameter of 4 mm. The thin neck allows the cutting head to enter a small hole.
  • Right or Left Hand — the direction of the thread is determined by the direction of the helix set in the programme. The same mill can thus produce both right and left-hand threads M1 x 0.25 mm.
  • Hole Before Milling — the internal thread is milled into a pre-drilled hole. Choose its diameter according to tables for thread M1 and clean it of chips before milling.
  • Brittle Tip — the cutting part for the M1 thread is very thin and may break under overload. Choose small feeds and work on a machine with a precise spindle. Store the mill in a case to prevent damage to the cutting edge or coating.
  • Package Contents — 1x coated thread mill M1 x 0.25 mm with a single flute and a 4 mm shank.

The coated mill for M1 x 0.25 mm thread is used for milling miniature metric threads on CNC machines. The sintered carbide body gives the tool the hardness needed for precise work. The cutting head with rainbow coating has a single flute, allowing the thread to form gradually, and its length and direction can be set in the programme. The mill is inserted into the holder with the silver shank 4 mm. It is applicable wherever very small M1 threads need to be milled.
