Vise, 3" Screwless Sine

3" Precision screwless sine vise.
Jaw width is 2.9" (73 mm), jaw depth is 1.4" (35 mm), jaw opening is 4" (100 mm).
The base size is 7" x 2.9" (190 mm x 73 mm) The center distance of the cylinders is 100.00 mm.
Hardened and precision ground to a tolerance of .0004” for both parallelism and squareness.
Sine range: 0 - 60°.
Jaw can be opened or closed without unbolting vise from work surface.

You can set the Sine Vise to a precise angle using our Space Blocks.

The Sine Vise Height Table shows how to set the sine vise.

Take a look at our vise comparison page before you choose a vise.

There are tables available that tell you how tall a stack of space blocks you need for a particular angle with a sine vise or sine bar. But nowadays, it is probably easier to find a calculator that has a sine function than the appropriate table. (There is such a calculator built into Windows--switch to scientific view.)

Here is how to use a calculator to calculate the stack of space blocks you need:
1. Enter the angle in decimal degrees (for example 15.2).
2. Press the SINE (or SIN) key (result 0.26218).
3. Press the X (multiply) key.
4. Enter the roll spacing (for example 5).
5. Press the = (equal) key (result 1.31095).
