3/16" Glass and Tile Drill (Spear Point Drill)

About this item:

• 3/16" Glass and Tile Drill (Spear Point Drill)
• Tungsten Carbide Glass and Tile Drill.
• These drills are designed for drilling glass, tile and other hard, brittle materials.
• The tungsten carbide spear point is extremely hard and features uniquely sharpened edges for fast penetration with a reduced need for end thrust.
• These drill bits cut clean round holes without chipping or material breakage, and work best with a lubricant such as water to extend bit life.
• When drilling multiple holes in ceramic tiles, or when drilling vitrified porcelain, we recommend using either Bordo ceramic tile drills, the Bordo mist drill product range or Brilliant Diamond core drills.
• Tungsten Carbide (commonly referred to as Carbide) is a chemical compound containing equal parts of tungsten and carbon atoms.
• Carbide is three times stiffer than steel and is much denser than either steel or titanium.
• Carbide has a very high abrasion resistance and can also withstand higher temperatures than standard HSS.
• Carbide tools are often used for machining hard materials such as ceramics and stainless steel, as well as in situations where other tools would wear away, such as high volume production runs.
• Because carbide tools maintain a sharp cutting edge better than other tools, they generally produce a better finish on parts, and their temperature resistance allows faster machining.
• Whilst tungsten carbide is extremely hard it is also brittle so it is important to avoid bit “chattering" as this is the most common cause of tool failure.
