BORDO HSS Co5 TiN Coated 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.
Titanium Nitride (TiN) Coated Countersinks have a very hard gold coloured surface finish.
This coating is only a few microns thick and is achieved by Physical Vapour Deposition (PVD).
This treatment results in reduced friction, greater heat dissipation and reduced cold welding – which means higher speed and feed rates with greatly increased tool life.
As with all surface coated tools, performance will deteriorate after resharpening.
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.

These Rotary Only ceramic tile drills provide outstanding performance and extended tool life in hard ceramic materials.
Unique cutting edge geometry in conjunction with high temperature brazing to ensure reliable and accurate drilling in multiple hole applications.
Use of water cooling will extend bit life.
Although these drill bits are not recommended for drilling vitrified porcelain, their superior multi-facet tungsten carbide tip enables them to drill most materials of this type, albeit with a reduced tool life.
These ceramic tile drills can also be used to successfully drill in brick, concrete and other masonry materials.
