BORDO Reduced Shank HSS 1/2″ Shank Metric Set
- Reduced shank HSS twist drill set.
- 118° notched point with 30° helix.
- Notched point is a variation on the standard chisel point, providing faster starting and reduced drill wander.
- 118° point angles are ideal for use in materials such as mild steel and cast iron.
- The 118° point creates easily controlled chips which are wide and thin.
- Bordo reduced shank HSS drills are ground and then a black finish is achieved by steam tempering, a thermal process resulting in a porous tool coating.
- This surface aids chip flow and heat dissipation.
- The drill is then ground a second time to achieve a bright finish on the shank and cutting edges.

Drill Bits/SetsSUTTON Jobber Drill Sets – Viper
Sutton Tools presents a breakthrough in twist drill technology, the revolutionary Viper Bit.
Drill Bits with bite!The Viper Bit has been developed specifically for the industrial trades person and the home handy person. For machine and hand held drilling in a wide range of ferrous & non-ferrous materials such as steel, aluminium, brass, wood & plastics. The Viper point design out-performs conventional HSS drill bits by delivering up to 2X faster drilling speeds. The 118° split point is self-centering, minimising wandering when starting and requires less pressure to be applied when drilling.

Drill Bits/SetsBORDO 4 Cutter Glass and Tile Drill Set
- 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.
