Tork Craft Taper Adaptor — MT3 to B22 (Morse → B-taper)
Adapt machines with an MT3 (Morse Taper #3) spindle to accept B22 taper-mount drill chucks. This hardened, precision-ground adaptor provides concentric seating for smooth, accurate drilling on drill presses, lathe tailstocks and milling machines in drill mode.
Features
- Conversion: MT3 male shank → B22 male taper for B22-bore chucks.
- Precision-ground tapers to minimize run-out and improve accuracy.
- Hardened steel construction for durability under workshop use.
- Smooth seating surfaces for reliable fit and easy release.
- Industry-standard geometry compatible with common machines and arbors.
Benefits
- Versatility: mount B22 drill chucks on MT3 machines without changing arbors.
- Accuracy: concentric fit improves hole quality and tool life.
- Fast setup: simple press-fit install; no special tools required for assembly.
Extra Information
- Clean and degrease both tapers before assembly; debris reduces holding power.
- Seat the chuck with firm hand pressure on a solid surface—avoid striking the chuck body.
- Remove using the machine’s eject feature or the correct taper drift/wedge.
Pro Tip
- Add a small witness mark across adaptor and chuck; reassembling in the same orientation can help preserve best concentricity.
- If insertion feels rough, lightly stone only raised burrs—never sand or file the precision seating surfaces.
