- 【Size and package】 right hand; Thread size: 3/8-16 UNC; outside diameter (OD): 30mm / 1.2"; Thickness: 11mm / 0.43"; Package includes 1pc machine thread cutting die.
- 【Durable Alloy Steel】Manufactured from hardened alloy tool steel, the thread cutting die has strong wear resistance and stable hardness, ensuring long service life when used on stainless steel, aluminium, cast iron and other common engineering materials.
- 【Strong Locking Force】The conical locking hole design ensures stability during threading. Just align the positioning groove with the screw in the middle of the die wrench, and then tighten. The end of the bar should be chamfered 45 degree to cut in.
- 【Easy Chip Removal】The round die design and precise cutting edges provides smooth threading, while recommended lubrication and periodic reverse rotation help improve chip removal, reduce resistance during repeated thread cutting operations.

This metric threading die is widely used in automotive, machinery and DIY projects, restoring external threads on bolts, rods, fasteners.

To ensure easy cut and prevent damage to the die teeth, the bar dia. should be smaller (about 0.05-0.15mm) than the nominal diameter of the required thread.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
