Features:

1 Stronger steel

Adopt imported 20CrMnTi to create strong steel and wear resistance

2 Higher accuracy

The shank has been tested tens of thousands of times and lasts longer than ordinary shank

3 High finish

The surface is polished and bright

4 Strong shock resistance

Vacuum quenching carbonitriding treatment has higher hardness and strong shock resistance

5 Higher precision

Shank body accuracy is 0.003, smaller runout, higher precision

6 High speed stability

High speed operation after (dynamic) dynamic balancing treatment

7 High concentricity

The inner hole of the handle is finely ground and the concentricity is high

8 Excellent details

Shank keyway through the fine grinding chamfer nose temple rounded without scratching hands

9  Low noise of high-speed machining. High precision of dynamic balance. Good toughness and wear resistance. High efficiency and long life

Strong and durable

Using the process of first infiltration and then quenching, high surface hardness, high wear resistance and fatigue strength to keep the heart with the strength and toughness of low carbon steel after quenching is able to withstand the impact load

G2.5 dynamic balance high precision

Further improve the comprehensive precision

Dynamic balance G2.5:30000RPM

Suitable for all kinds of CNC engraving machine and other equipment

Widely used in milling, boring, drilling, tapping and so on

High concentricity of one molding

Stable performance to ensure the accuracy of work

Electroplating anti-rust coating technology

Body coating added plating anti-rust coating process, waterproof, anti-oil, anti-rust. Keep the taper unchanged to improve accuracy
