TUNA Microblock Ball Vise With Inside Ring Holder Attachment Set

A ball vise holds a ring or a small part steady and lets you turn it to any angle without releasing it, which makes clean stone setting and engraving possible at the bench. The TUNA Microblock Ball Vise from Ikohe is built in matte stainless steel and turns on precision ball bearings for stable 360° workpiece access, whether you work under a microscope, under a magnifier, or in the open. The 18-piece expandable collet set and accessory hardware that ship with it make it a ready-to-use system across a wide range of ring sizes and holding tasks.

Features

• Matte stainless steel finish resists glare under bright bench and microscope lighting
• Precision ball bearings provide smooth, even 360° rotation
• Self-centering jaws maintain secure, even pressure on the workpiece
• 18-piece expandable collet set accommodates rings from size 4–16 (15mm–25mm ID)
• 18 mounting holes of 3.7mm diameter, six of them threaded, for flexible attachment configurations
• Peg set extends the maximum jaw opening to 2.88" (72.5mm) for larger workpieces

Compatibility

• Suitable for use with microscopes, GRS-style systems, Optivisors, and similar magnification setups
• Works with flex shaft and micromotor handpieces for stone setting and engraving
