Overview

Wilton Verti-Lock Machine Vises

Wilton Verti-Lock machine vises are heavy-duty, precision work-holding tools designed primarily for milling machines, drilling machines, and grinders. Modeled after the industry-standard Kurt-style vise, they feature a unique "verti-lock" mechanism that prevents the movable jaw from lifting under heavy clamping loads, ensuring your workpiece stays perfectly flat.

Key features:

* Rugged Construction: Built with ductile alloy and cast iron bodies (often 60,000 to 80,000 psi) and flame-hardened beds for maximum durability, wear resistance, and long-term accuracy
* Enclosed Spindle: The vise screw/spindle is completely enclosed to protect it from damaging metal chips, shavings, and other milling debris
* High Clamping Force: They typically feature fixed jaw ratings between 85,000 psi and sliding jaw ratings around 70,000 psi for secure, vibration-free machining
* Precision Ground: The sliding jaws are annealed and surface-ground, and many models provide parallel accuracies down to 0.0005 in.
* Popular models:
-- 5 in.: Offers a 5 in. jaw width, roughly 4.5 in. to 5 in. jaw opening, and is great for slightly smaller mills or highly repetitive tasks
-- 6 in.: The most versatile and common size, featuring a 6 in. jaw width and a 7.5 in. opening capacity
-- 8 in.: Ideal for heavy-duty industrial machining, offering an 8 in. jaw width and a 7.5 in. to 10.5 in. opening
