Compared with the traditional BT Tool holder, HSK tool holder has the following features of structure and performance:

(1).Double face simultaneous positioning

One of the most significant features of HSK tool holder is that the conical and flange end faces are in contact with the spindle taper and end faces simultaneously.

(2).Hollow structure

The HSK tool holder adopts hollow thin wall structure, which the structure is more suitable for high speed cutting. It is also easier to arrange and install the clamping mechanism, and easy to realize the clamping from the inside to the outside.

(3).1:10 taper shank

HSK tool holder adopts 1:10 (accurate value is 1:9.98) small taper, and the taper length is short. This kind of taper shank has two advantages:

1). Small taper is conductive to self-locking of the shank, making clamping more reliable;

2). After each tool change, the consistency of the contact area between the tool shank taper and the spindle taper hole is good, which can improve the repeated positioning accuracy of the tool shank tool change.

Features:

1. Material: 20CrMnTi;

2. Hardness: 56-58HRC;

3. Carbon depth:＞0.8；

4. Integrated design of the rob and chuck can avoid the rob and chuck separate, enhance reliability and stability;

5. Self-tightening, hold the chuck slightly, when drilling, holding power is enhancing with the torque increasing and develop obvious strong holding power to prevent the drill remove;

6. Coating surface enhance surface hardness durability, anti-rust and anti-corrosion better, precision more stable, surface more smooth and appearance more nice.

Our advantages

7. High accuracy;

8. Large clamping force;

9. Dust tightness is good;

10. Anti-rust and anti-corrosion

11. High rigidity
