Precision Workholding for Grinding and Toolroom Applications
Designed for the meticulous requirements of mold making and precision machining, this 2-inch screwless vise offers a “no-lift” clamping solution. Unlike standard vises that may experience jaw tilt, the screwless design utilizes a downward-pulling force that ensures your workpiece remains perfectly parallel to the machine table or surface plate. The integrated side slots (G-slots) allow for easy clamping to machine tables or sine plates, making it a versatile addition to any CNC or manual setup.
Hardened Durability & Superior Accuracy
Manufactured from high-grade alloy steel and hardened to HRC 56-60, this vise is built to resist wear and maintain its geometric integrity over time. Every surface is precision ground to achieve a squareness and parallelism within .0002″. This level of accuracy is essential for EDM operations, precision grinding, and 5-axis inspection routines where even a micron of deviation can lead to out-of-tolerance parts.
Shop-Floor Benefits
- One-Piece Construction: Enhances rigidity and maintains alignment under clamping pressure.
- Screwless Design: Fast adjustment via the pin-hole system, allowing for quick transitions between different workpiece sizes.
- Versatile Mounting: Featured side slots allow for secure horizontal or vertical mounting.
- Corrosion Resistant Finish: Precision ground surfaces are treated to withstand standard shop oils and coolants.

Frequently Asked Questions
Q: Why is this vise called “screwless”?
A: It utilizes a pin and hole adjustment system rather than a lead screw. This creates a downward clamping force that prevents the jaw from lifting, which is critical for precision grinding.
Q: Can I use this vise for heavy milling?
A: While highly rigid, screwless vises are primarily designed for precision grinding, inspection, and light milling. For heavy material removal, a traditional Kurt-style vise is recommended.
Q: Is this vise compatible with the 3900-2012 model?
A: Yes, the 3900-0022 is being superseded by the 3900-2012. They share the same core dimensions and precision standards.
