Taper Adapter Mt3 - Jt4

Extra Information

• Thoroughly clean and degrease both tapers before assembly.
• Seat the chuck with a firm hand press; avoid hammering on the chuck body.
• Remove using the machine’s eject feature or correct taper drift/wedge.

Features

• Conversion: MT3 male shank → JT4 male taper (for JT4-bore chucks).
• Precision-ground tapers for low run-out and reliable grip.
• Hardened steel construction for durability in workshop use.
• Smooth finish for clean seating and easy release.
• Industry-standard geometry compatible with common machines and arbors.

Benefits

• Versatility: mount JT4 chucks on MT3 machines without replacing arbors.
• Accuracy: concentric fit improves hole quality and tool life.
• Quick setup: press-fit assembly—no special tools needed.

Safety

• Disconnect power before installing/removing chucks or adapters.
• Ensure tapers are fully seated; avoid side-loading small drills.
• Use rotary drilling only—do not use hammer/impact with taper-mounted chucks.
• Wear eye protection and secure the workpiece properly.
