Frequently Asked Questions
What is a combined ISO 30 drill chuck?
It is a quick-change chuck that combines a drill holder and coupling cone in a single body, mountable directly into the machine spindle nose.
The "combined chuck" system eliminates the need for a separate shank, reducing the number of components and the risk of misalignment. Suitable for series production and quick drill bit changes.
Which machine is it mounted on?
It mounts directly onto the spindle nose with an ISO 30 taper.
Morse Taper 2 (MT 2) is typical for bench drills, MT 3 for professional drills, MT 4 for industrial drills. ISO 30 and ISO 40 are tapers for precision bed milling machines.
What is its drilling capacity? 16 mm
Clamping capacity up to Ø 16 mm on the drill bit shank.
The capacity indicates the maximum diameter of the drill bit shank that the chuck can accommodate. For larger diameter holes, specific core drills or milling cutters are required.
Is it key-tightened or keyless?
Combined chucks are tightened with the supplied chuck key, ensuring a secure grip for intensive use.
Key tightening is more secure than quick-release for operations with high torque or hard materials. The key must be kept near the machine and never left in the chuck during operation.
How is it maintained?
Regular cleaning of the jaws after use, removal of chips and coolant, lubrication with specific spindle oil every 50-100 hours of use.
A jaw that moves with difficulty indicates chip accumulation or oxidation. Disassemble the chuck, clean the sliding surfaces, and apply light oil. Replace the chuck if concentricity exceeds 0.1 mm.
