Bordo 2552-S1 4 Cutter Glass and Tile Drill Set

Tungsten Carbide 4 Cutter

• Precision diamond ground, double chamfered spear point tungsten carbide for fast cutting and extreme tool life (when used at slow to medium speeds).
• Fast starting with reduced bit wander. Suitable for use in: glazed and un-glazed ceramic tiles, glazed porcelain tiles, through-body porcelain tiles, plate (float) glass and annealed glass.
• Not suitable for use with toughened or laminated safety glass.
• Use a slow speed with steady but gentle pressure.
• Reduce the pressure at break through.
• For increased bit life use a cutting fluid/lubricant such as water or turpentine to reduce heat.
• When drilling multiple holes in ceramic tiles or when drilling vitrified porcelain use Bordo ceramic tile drills or a Bordo diamond drilling system.

Drill Bit Material

• Drill Bit Material 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.
