AccuThread™ 856
Thread mills drastically reduce the occurrences of scrap when compared to taps, which makes them desirable when manufacturing large and/or costly components. AccuThread™ 856 is a premium thread milling product backed by Allied’s experienced technical staff. AccuThread™ 856 provides quality threads when compared to other thread making processes.
Advantages
- Provides a 25-50% increase in tool life over the competition
- Increased strength and rigidity when cutting forces are applied
- Standard cutting lengths accommodate multiple applications without the need for an engineered special
- Re-sharpening service available
Features
- Allied's proprietary AM210® coating
- Thicker core
- Helical flutes
- Wide range of forms and pitches
- Imperial and metric shanks
- Online programming

AccuThread™ T3
The AccuThread T3 is built for machining hardened or hard-to-machine materials such as stainless steel, tool steel, and high temp alloys. It is designed to machine only 3 threads at a time, reducing tool pressure and dramatically increasing the chances of tool survival.
Advantages
- Improves tool life and produces a precise thread form
- Cuts harder materials and produces deeper threads than a standard thread mill
- Improves cycle time and tool life
Features
- Left hand cutting allows the tool to climb mill while it moves from top to bottom, creating a right-handed thread
- 3 cutting teeth cuts minimal threads at once and reduces side deflection
- AM210® multi-layer PVD coating
