Why choose to shrink Fit tool holders  
1. Achieved using an inexpensive hot air heater
2  Hot loading and unloading operation
3, Can be safely immersed in cooling
4, No matter the placement, there will be no overheating with a wall thickness of 1.5mm
5, Ultra-thin apex part and abundant shape change
6. Hot refilling of φ3/32 ~ 1" can be performed without replacing the heating nozzle.
7. High rigidity-shortest tool protrusion
8. Hot-fitting tool holders do not require a nut and collet for holding the tool with a collet holder. It is an integrated type consisting of only the main body.
Half angle 3 °, wall thickness 1.5mm is a very light and slender shape, try to avoid interference with the workpiece.
Since the protruding length of the tool can be set to the shortest, high rigidity, strong and stable cutting can be performed without flutter, and a high-quality machined surface is obtained. 
And we guarantee that we can dramatically increase the tool life.High accuracy = extended tool life
There are no parts (nuts, collets, etc.), which can be accurate regardless of proficiency, Installation with high accuracy

Because there is no need to adjust the clamping degree, anyone can install the tools with high precision ,high-precision clamping will be extend the tool long life time
Clamping tools more than 2,000 times.
