Flared Hole

Create flares around already-cut holes in sheet metal up to 3/16" thick to make the edges stronger and more rigid. Also known as dimple dies. Press a male and female die together using a hydraulic press. When you don’t have access to a hydraulic press or your material won’t fit in a press, bolt the dies together. For making multiple flares quickly, use a hydraulic knockout punch driver. Dies are made of hardened steel for strength and durability.
