GIVIMO 3.86-in Steel Engraving Block Ball Vise with 5-in Chrome-Plated Ball 360-Degree Rotating Dual-Ball Bearing Base Coaxial Control Jaws and 35-Piece Attachment Set Including Ring Clamps Plate Clamps Pins and Hex Wrench

5-in Chrome-Plated Steel Ball: A 127-mm steel ball finished in hardened chrome plating pairs with an electroplated black core jaw so bench humidity does not leave pitting on the seat

360-Degree Rotation on Dual Bearings: A dual-ball bearing base turns the workpiece a full circle with no internal looseness so a graver angle changes without unclamping the piece

3.86-in Maximum Jaw Opening: Coaxial control jaws open to 98 mm and close on upgraded pins that hold rings and flat plate square rather than drifting under tool pressure

35-Piece Attachment Kit: Ring clamps plate clamps accessory pins and a hex wrench arrive in the box so stones settings and plate work of different shapes each get a proper grip

Low Profile for Microscope Work: A 5.7 x 5.7 x 6.7 in envelope on a rubber base sits low enough to work under a microscope while 20.3 lb of mass damps chatter during cutting
