BORDO HSS Co5 Bright Cross Hole 90° Countersink
- Cross hole countersinks are ideal for countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals.
- The intersection of the hole and cone form the cutting edge on the tool.
- The cone is not truly symmetrical as it is essential that the cone retreats away from the cutting edge as the tool rotates.
- If this does not occur the cutting edge will lack clearance and rub rather than bite into the material.
- This clearance is referred to as cutting relief.
- The radially relieved single cutting edge provide fast stock removal with low vibration for chatter- free operation ensuring the smoothest finish.
- These tools are best used as deburring tools, where a burr, or sharp edge, from a previous machining operation needs to be removed for cosmetic and safety reasons, however they may be used in softer materials (such as wood or plastic) to create a countersunk hole for a screw.

- 4-10mm 5 Pce 4 Cutter Glass and Tile Drill Set
- Tungsten Carbide 4 Cutter Glass and Tile Drill Set
- 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, 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.
