• Very high total rigidity due to optimised design.
• With RFID/Balluffchip bore.
• Axial length adjustment, adjustment travel 10 mm.
• Flexible due to use of reducing sleeves.

Advantage: Very high transmitted torque (550 Nm), providing high process reliability.

• Ideal damping characteristics, resulting in optimum surface finishes, increased tool life and 30 7550_20 spindle protection.

Application: Especially for heavy-duty milling.

• For clamping tools with shank tolerance h6.

Supplied with: Hexagon socket drive with T-handle.

Optional extras: Coolant tube No. 309880, socket wrench No. 309890, reducing adapters No. 302135 – 302187.

Note: Caution in the case of extra-long tools and TPC machining. 30 7552_20

GARANT Master Chuck hydraulic chuck slim –

ISO 12164-1 (DIN 69893-1)

• Slim design (4.5° contour, identical to shrink contour according to DIN 69882-8) 30 7502 With RFID/Balluffchip bore. Same properties as shrink-fit chucks:

Axial length adjustment, adjustment travel 10 mm. Accuracy. Reducing adapters can be used. Extremely slim, identical interference contour.

• Advantages over shrink-fit chucks:
• Temperature resistant up to 120°C for 4 hours.
• Better damping.
• Up to 10× more clamping operations possible compared to a standard hydraulic chuck. Simpler to use. Very low tightening torque of the clamping screw – easy handling.
• Flexibility (through reducing adapters).
• Patented new hydraulic clamping system – reliable and durable premium radial run-out.
• No shrink-fit units required

Application: Particularly for use in tool and mould making where a reduced interference contour is required. (costs, energy consumption).

For drilling, reaming and milling. For clamping tools with shank tolerance h6. A

Optional extras: Coolant tube No. 309880, L socket wrench No. 309890, L reducing adapters No. 302140; 302135 302145 302147 each size 12 and V No. 302150; 302155; 302160; 302165 each size 20.
