You choose a rougher Mũi taro ren tay (tạo ren trong) when your process starts with a stable lead in, especially when you want a predictable first pass on a metric ren trong.
DIN 2181 and HSS-G in the product name indicate a Mũi taro ren tay (tạo ren trong) design made for practical shop work where tool control and consistent geometry matter.
Lưu ý Align the tool carefully and use lubrication suitable for your workpiece material to support surface quality and tool life.
Keep the tool aligned to the bore axis and apply steady torque. Use a suitable Chất bôi trơn cắt gọt ren and avoid forcing the tap when resistance rises, because misalignment can mark the first thread turns.
Does the title value M 90 x 2.0 include the pitch information you need?Yes. The thread designation in the title includes both diameter and pitch, which helps you distinguish fine pitch variants from other executions of the same nominal diameter.
Which holder or wrench is appropriate?Use a Tay quay taro or suitable holder that clamps the square reliably and keeps the tool aligned. Select the interface based on your tap size and your available guidance method.
How do you handle chips during tapping?Use suitable lubrication and advance with controlled torque so chips can evacuate through the flute space. Clean the tool as needed to avoid chip packing and surface scoring.
What is the role of the DIN 2181 reference?DIN 2181 supports standardised identification for Mũi taro ren tay (tạo ren trong). It helps you align purchasing, documentation, and workshop instructions with a recognised designation.
How do you select the correct variant for your drawing?Match the metric thread designation in your drawing to the product title, including the pitch value, because the pitch differentiates otherwise similar diameters.
