MBT SuperFinisher Ball Nose Insert

Precision ground, harder grade, for semi-finish and finish milling. Excellent choice for unattended finish milling at small depth and high speeds and feed rates.

BDS Flat Bottom Insert

Precision ground, non-chipbreaker. Unique crossover design between flat bottom FB and back draft BD inserts. Allows straight walls with a larger step down than BD, but less cutting forces than FB; allows higher cutting speeds and feeds.

HF (High Feed) Insert

The HF insert can be used in the following applications: Roughing, semi-finish of all softer materials. Nickel-based alloys and Stainless steel alloys (XRN coated) to pre-heat treated Tool steels (TLN coated). It can be used for roughing and semi-finishing of heat-treated materials up to 48 HRc.

New TOBD-NF Back Draft Inserts for Non-Ferrous Materials

Millstar’s new TOBD-NF insert is specifically designed for high speed and high feed roughing of Aluminum, but also has the versatility to be used for fine finishing as well. This unique cutting edge design allows the chips to flow freely up the flute allowing higher speeds and feeds. The TOBD-NF comes in diameters from 1/2 inch (12mm) up to 1 inch (25mm) and fits into our standard flat type tool holders making the holders more versatile than ever.

Carbide Modular Shrink System

Millstar’s Shrink System offers versatility, strength and accuracy. The carbide shanks and heads are interchangeable between inch and metric versions. Metric heads fit on inch shanks and inch heads fit on metric shanks. The 12mm and 1/2 inch shanks will accept any head that is the same diameter or smaller (see chart for connectivity). The carbide shank offers strength and rigidity and the shrink tolerances offer better accuracy than screw on type systems. These tools are designed for high speed machining and hard metal machining and will allow for better tool life as well as better surface finishes.
