Epoch D Thread Mill
Enables a single tool to cut the pilot hole and threads at the same time in hardened materials with hardnesses of 45HRC or higher.
Epoch D Thread Mill for PT,NPT Threads
Achieving a good finished surface without tear!
Features of Epoch Thread Mill
Tough and strong edge design Tip shape that reducesriStting résistance tool bending.
Drastically redugesftool breakage, a particular problem
Epoch Thread Mills are designed with no incomplète thread and Epoch D Thread Mills hâve only one incomplète thread, making them idéal for when you want to perform thread milling to the bottom of shallow holes.
Since the load is smaller than when using taps, these tools can be used even on machines having low-powered spindle.
In addition, spécial tooling such as tapping holders are not necessary.
By using a tool with a diameter smaller than the inside diameter of the thread, cutting chips are smaller and chip évacuation is improved.
The risk of the tool breaking off inside the hole is reduced as a resuit.
Right hand, left-hand and fine thread milling can be performed by just changing the NC program.
The nominal diameters of the coarse threads and fine threads that can be processed with the same tool are different. (Example: For ET-1.25-16-PN, coarse thread is M8 * P1.25 and fine thread is M10 * P1.25)
