PRECISION FOR PERFECT THREADING

WhizThread’s innovative design features four precision-ground cutting edges, which provide exceptional stability during the threading process. This stability is crucial as it minimizes vibrations and tool deflection, leading to a smoother and more consistent cut. As a result, the surface finish of the threaded component is significantly improved, achieving a high level of precision and quality.

Advantages of WhizThread

Precision-ground threading inserts ranging from 0,2-2,0 mm pitch (120, 12 TPI).
Tangential mounting for better stability.
Threading tools with four cutting edges.
Capable of threading up to the shoulder.
Exceptional performance for Trapezoidal and ACME threads.

BOOSTING STABILITY

The enhanced stability allows for faster machining speeds and feeds, reducing the overall cycle time. This means that not only is the quality of the finished product superior, but the efficiency of the production process is also greatly increased. In essence, WhizThread combines high performance with time-saving benefits, making it an excellent choice for precision threading applications.

TR, ACME and Stub ACME

These threading inserts feature additional side clearance along the profile while maintaining exceptional stability.

Perfect for all tolerance classes: All inserts are made according to ISO and AISI standards.
Great clearance: Even when helix angle varies at major and minor diameters.
Good surface finish: Thanks to sufficient clearance.
Outstanding stability: Compared to traditional design threading inserts.
Productivity increases: Use higher speeds and feeds thanks to the combination of high stability and reliefs.
Customized inserts: Can also be made with similar benefits, for module and other thread types.

WhizGuide

Select your holders with the ideal cutting angle

1

Cutting angle: +2°, +4°,+6°

The secret of threading really small parts is to select the correct cutting angle of the toolholder.
WhizThread tool holders are available with a 2°, 4° and +6° or bigger cutting angle.

2

Pitch and diameter

The WhizGuide-table recommends an appropriate toolholder, depending on part thread and diameter.
If you have a very high pitch-to-diameter-ratio we advice special toolholders.
