silicon carbide vs bullet types

Know Rotary Saw Blades - Fire Rescue Magazine

30/9/2008· Silicon carbide discs are made to cut concrete, as well as stone, brick, soft aggregate and masonry—materials we encounter when performing forcible entry and often on flat roofs. These discs are fairly inexpensive (usually under $20) and, as with all abrasive discs, wear out rather quickly and will need to be replaced during an emergency if many cuts are required.

Bulletproof vest - Wikipedia

History Early modern era In 1538, Francesco Maria della Rovere commissioned Filippo Negroli to create a bulletproof vest. In 1561, Maximilian II, Holy Roman Emperor is recorded as testing his armor against gun-fire. Similarly, in 1590 Sir Henry Lee expected his Greenwich armor to be "pistol proof".
