Self-clamping drill chuck 1-13 mm BT40 - the universal standard for machining centers
The 1-13 mm self-clamping drill chuck with BT40 mounting is the most popular diameter range in professional tool shops and production departments. The MAS-403-compliant interface (JIS B 6339-2) guarantees compatibility with Japanese machining centers, and a minimum axial runout of 0.04 mm at a distance of 55 mm from the jaws ensures the precision required for machining responsible parts. The Balance Taper system combines low weight with high joint rigidity.
Why choose the BT40 1-13 mm self-clamping chuck
- Universal clamping range from 1 to 13 mm - covers 95 percent of standard drills used in the industry, from precision micro holes to typical diameters
- Japanese BT40 interface according to MAS-403 - full compatibility with Mazak, Okuma, Mori Seiki centers and practical interchangeability with European SK40 taper
- Run-outparameter of 0.04 mm at 55 mm measuring point - precision grade to extend drill bit life and eliminate hole positioning errors
- Keyless tool change - self-clamping mechanism reduces changeover time and eliminates the risk of losing fastening keys
- Reinforced design up to 12,000 RPM - stable clamping at high speeds with a torque transmission of up to 125 Nm
The 1-13 mm range is the choice of specialists who prefer a standard, proven tool format. The drill chuck for CNC milling machines with the BT40 system proves its worth in mass production of precision parts, where repeatability and speed of changeover are crucial. Reduced weight design lowers the load on spindle bearings without compromising rigidity. Choose a solution trusted by thousands of workshops worldwide.
Frequently asked questions
1. Why is the 1-13 mm range more popular than 1-16 mm?
Most drilling operations in the industry use diameters up to 13 mm. This range covers standard workshop needs, is lighter and offers better rigidity for typical applications than versions with a wider range.
2. Does the BT40 1-13 mm chuck fit European machine tools?
The BT40 standard is virtually interchangeable with the European SK40 - both use an identical taper angle of 7:24. However, it is worth checking the spindle specifications before purchasing, as there may be subtle design differences between manufacturers.
3. What drills can be clamped in a chuck with a range of 1-13 mm?
The system clamps all standard HSS, HSSE and VHM drills with diameters from 1 mm to 13 mm. This includes precision micro drills as well as typical workshop diameters used in steel, aluminum and plastics.
