Advantages of drill bushings
In addition to the original purpose of guiding drills, drill bushings support a wide range of positioning tasks thanks to their design. This is often achieved in conjunction with guide pins, such as GN 771.1, or indexing plungers.
Drill bushing designs
Drill bushings with cylindrical bore are typically available in two designs:
- Drill bushing DIN 172 "headed drill bushing"
- Drill bushing DIN 179 "headless drill bushing"
In addition, the Winco selection has designs with conical bore GN 172.1 and GN 179.1, which pair especially well with conical indexing plungers GN 817.5.
All drill bushings and guide bushings are made of hardened steel.
