Frequently asked questions
What is a combined Morse taper 2 (MT 2) drill chuck?
It is a quick-change chuck that combines a drill holder and a tapered coupling in a single body, mountable directly into the machine spindle.
The "combined taper" system eliminates the need for a separate tang, reducing the number of components and the risk of misalignment. Suitable for series production and quick drill bit changes.
Which machine does it mount on?
It mounts directly onto the spindle nose with a Morse taper 2 (MT 2) connection.
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 connections for precision bench milling machines.
What is its drilling capacity? 13 mm
Clamping capacity up to Ø 13 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 needed.
Is it key-tightened or keyless?
Combined taper chucks are tightened with the supplied chuck key, ensuring secure clamping for intensive use.
Key tightening is more secure than quick clamping 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 chuck oil every 50-100 hours of use.
A jaw that moves with difficulty indicates an accumulation of chips or oxidation. Disassemble the chuck, clean the sliding surfaces, and apply light oil. Replace the chuck if concentricity exceeds 0.1 mm.
