DIN 69880 Type C3 VDI External Tool Holder With Coolant Hole For CNC Lathe Turning Grooving

C3 VDI Tool Holder

This C3 VDI external tool holder complies with DIN 69880 standard, designed for CNC lathe VDI turrets. It is specially used for external turning, grooving and facing processes with integrated coolant hole design.

Core Features & Performance

1. Standard C3 VDI Shank Interface

Knurled cylindrical shank ensures tight locking on VDI turret, quick installation without extra modification.

2. Built-in Coolant Channel

Side coolant port sprays cutting fluid directly to cutting edge, reduces heat, extends insert service life and smooths workpiece surface finish.

3. High-rigidity Split Clamping Structure

Multi-bolt fastening eliminates tool vibration and runout, maintains stable precision during heavy stock removal.

4. Premium Alloy Steel Material

Whole body adopts quenched alloy steel with black oxide anti-rust coating, great hardness, wear resistance and long service life for continuous mass production.

5. Wide Machining Compatibility

Suitable for external turning, grooving and facing inserts, fits shaft parts, hydraulic fittings and auto hardware processing.

Application Scenarios

Widely matched with VDI turret CNC lathes for batch machining steel, stainless steel, aluminum alloy and copper workpieces in automotive, hydraulic and general machinery workshops.
