Clear Radius Bullnose Blade
Clear Radius Bullnose Blade Core is shaped to diameter and radius in one step leaving small ridges throughout the core surfaces. The core radius is shaped a 2nd time in microns for a more precise radius and well-balanced blade than a wheel. The diamond is then bonded. Clear Radius Bullnose Blade idea was started by the explosion of tile usage with no finish edges (round over, bullnose). Today's thin hard porcelain tile 1/4 inch and 1/2 inch tiles needed a blade with less wobble, chipping, cracking and easy to use on thin porcelain tile. We added an additional step of clearing the radius using micron measurements in manufacturing. By adding the clear radius step you can now bullnose the thinner porcelain tiles with less cracking. iron Rock's clear radius produces a smooth honed finish.
Demi Profile Wheel
Demi Profile Wheel Core is shaped to diameter and radius in one step leaving small ridges ( milled rough finish ) throughout the core surfaces. The diamond is then bonded. The small ridges in the core produce a slight wobble that causes cracking and chipping in hard porcelain tile.
The Demi Profile Wheel has been produced since late 1960 to profile 20mm 3/4 in. and use to bullnose thicker material granite, brick, and stone for large dual rail low RPM machines. Good for round over on the thick material when a smooth finish is not required.
