Product Description

Exceptionally suitable jaws for small bowl and miniature unsupported spigot turning work. Ideally suited for mini/midi lathe work, or for work below the size that can be handled by the 50mm (2″) jaw set.

• A quick and easy work holding solution for small bowls and small unsupported spigot work.
• A great range of smaller projects can be mounted and turned using either the expansion mode (mostly for bowls) or the contraction mode (mostly for spigots)
• Multiple turned pieces (i.e. lace bobbins) can be turned from dowel stock
• Made from K1045 steel for maximum structural strength.
• Only NOVA chucks give you the same jaw fixing system and same insert/adapter system across all standard chuck models, giving you optimal flexibility. All accessory jaws in the Standard Chuck range will fit all the Standard NOVA (NOVA Infinity Quick Change requires optional accessory Upgrade Kit or Retro Fit Kit to attach standard NOVA Accessories) Some jaws, however, are not recommended for use on all NOVA Chucks due to sizing . See manual for recommendations.
• NOVA chucks are specially designed so the jaws cut into the wood, grip firmly in the contraction mode and provide high tear out strength.
