Description
The 155L Hold-Tight Machine Vice from the 6523 Series is a precision clamping solution designed for milling machines, drill presses, grinders and other equipment that require high accuracy and safe workholding. It delivers a secure, repeatable grip on a wide range of workpieces, helping you achieve accurate cuts and reduce setup time in busy workshops. With four-position jaw capability and hardened steel inserts, it combines versatility with long-term precision in a compact, durable package.
- 4-position jaw capability: Four jaw positions let you clamp different workpiece sizes and shapes without flipping or swapping jaws, increasing versatility and reducing setup time.
- Hardened, ground steel jaw inserts: Hardened and ground inserts provide longer life while maintaining accuracy and repeatability across multiple uses, reducing wear-related downtime.
- Rigid cast-iron construction with included handcrank slot nuts: The body and movable jaw are made of high-quality cast iron for stability, delivering reliable clamping; the standard handcrank slot nuts enable quick, secure adjustments.
With its versatile jaw arrangement and durable construction, this vice minimizes setup time, reduces rework, and delivers repeatable, high-precision results across a wide range of applications. The combination of hardened inserts and a rigid body keeps cutting forces steady, helping you finish jobs faster and with confidence.
