Low-Profile Fixture Clamps
Blunt Edge
Knife Edge
Install these clamps into a slot in your fixture to grip at the bottom of workpiece edges, giving the cutting tool maximum access to your workpiece. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.
Blunt edge is less likely to mar your workpiece. Knife edge bites into your workpiece for faster and more aggressive machining.
Clamps with brass heads are nonmarring when used with steel and aluminum workpieces.
