Pro-Series AT-MV4 4″ Angle-Tight Positive-Lock Milling Vise
The Pro-Series AT-MV4 milling vise provides secure, accurate workholding for milling, drilling, shaping, and general metalworking applications. Featuring a precision-ground construction and an Angle-Tight Positive-Lock clamping mechanism, this 4-inch milling vise is designed to help maintain workpiece stability during machining.
Its compact size makes it well suited for smaller milling machines, toolrooms, maintenance departments, fabrication shops, and precision machining applications where dependable workholding is essential.
Angle-Tight Positive-Lock Clamping System
The AT-MV4 incorporates an Angle-Tight Positive-Lock mechanism that applies downward clamping force as the movable jaw is tightened.
This design helps minimize jaw lift, a common concern with conventional machine vises, and promotes consistent workpiece positioning during cutting operations.
By helping keep the workpiece securely seated against the vise bed or appropriate parallels, the positive-lock mechanism supports reliable machining setups.
Precision-Ground Construction
The Pro-Series AT-MV4 features precision-ground surfaces designed to support accurate alignment and repeatable workpiece positioning.
Its heavy-duty construction provides a stable clamping platform for milling, drilling, shaping, and general machine shop operations.
