The Allied Maxcut range of 'AccuThread' thread mills provide a fast and precise solution for high speed internal thread milling applications, including both solid carbide and indexable inserts covering a range of metric ISO, British Standard (BS) and other widely used parallel and taper thread forms.
All thread mills are PVD TiCN coated as standard with the new 'AccuThread' range having the additional benefit of AMEC's newly patented AM210 coating
Both the solid and indexable insert ranges are designed to allow full form profiles to be achieved to the full thread depth which also enables threading to within one full pitch for blind holes and bores. Also, the cutting geometry of the thread mills is optimised to reduce machine power requirements during thread cutting operations.
The solid carbide thread mills cover metric ISO 60O thread sizes from M1.6 to M64, in both standard and fine pitch forms, as well as BS 55O threads from 1/16" to 2". In addition, thread mills for 60O NPT, NPTF and various UN forms are available from 1/16" to 6", depending upon the thread type.
The 80O PG form for cable conduits is also included within the range covering all standard sizes from PG7 to PG48. Straight fluted thread mills are available across the range with a helical fluted option provided on ISO and UN thread mills as well as a range of solid carbide shell thread mills covering M48, M56 and M64 as well as 1 ¾", 2 ½" and 2 ¾" sizes.
AMEC's indexable inserts and tool holders cover thread forms for ISO, UN and NPSM threads with pitch ranges from 1mm to 6mm, 48 to 3.5 TPI and 18 to 8 TPI respectively. Inserts for cutting BSP, BSPT, NPT, NPTF and NPSF threads are also incorporated in the range, giving a wide choice as well as high accuracy and repeatability with minimum of down time between insert changes.
All inserts are manufactured in four different lengths of 14mm, 21mm, 30mm and 40mm to meet specific production requirements. Three different styles of tool holder are provided within the range including single insert, dual insert and a four insert designs to provide optimum performance.
