Mini Mill-Thread

MTSB type

An innovative solid carbide thread mills with internal coolant bore and increased
number of flutes.

The coolant bore provides high coolant pressure through the tool into the application
pre-hole and washes the chips away during the threading cycle.
The coolant liquid also cools the tool cutting edge very efficiently.

Excellent solution for: Demonstration

Small and deep threads.
Thread milling operations on horizontal machining centers, where chips are
concentrated at the bottom of the thread and external coolant can’t wash the chips
away.

Complicated applications where external coolant is inefficient or can’t reach the
machined area.
Case where the tool collet is close to the application pre-hole and blocks the
external coolant.

Can also be used in any other thread milling operation (blind or through hole) that
requires improved performance with high thread quality.

Features:

Increased number of flutes for high performance, shorter cycle time and improved
tool life.

Working at high machining parameters (increasing productivity).
Advanced PVD triple coating.

Threads size: M1.2 up to M8
0-80 up to 12-24UNC

Carbide grade: MT7

Our MT7 sub-micron grade with it’s advanced PVD triple coating provides extremely
high heat resistance along with smooth cutting action, delivering high performance under
normal machining conditions.
