Sine Bars


Measure, mark, and inspect exact angles on dies and other precision parts. These sine bars are smaller and less expensive than sine plates and more accurate than other measuring tools, such as protractors. They are made from hardened, precision-ground steel to resist wear and ensure accurate measurements over time.
Sine Plates

Use with gauge blocks to tilt the plate surface to a precise angle. Measure angles on your workpiece or set up a part for precision grinding. Do not use for milling and drilling machine processes.
Magnetic Sine Plates

Turn the handle to switch the magnet on and secure steel parts—no need for clamps or screws. Use these plates with gauge blocks to tilt the plate surface to a precise angle. Measure angles on your workpiece or set up a part for precision grinding. Do not use for milling and drilling machine processes.

Any-Which-Way Angle Plates

The handle extends the full length and height of these plates for use on any of their six sides. Ensure accurate right angles and hold workpieces and fixtures perpendicular to a machine table by securing them to the plate with clamps.
