BORDO SDS Max DELTABIT 305mm
- The Bordo range of Deltabit SDS Plus and SDS Max solid tungsten carbide head masonry drill bits offer outstanding performance in a wide variety of drilling applications.
- Deltabits offer specific advantages over standard SDS masonry bits.
- Three edge cutter provides high durability and improved drilling speed.
- Tungsten carbide head is permanently bonded to the shank through the use of a unique fusion welding technology, rather than brazing.
- Eliminates rifling – drilling holes close to perfect roundness.
- Extremely round holes result in improved fastener performance by increasing pull out loads.
- More accurate hole starting without bit walk.
- Limited circumferential wear.
- Drills through reinforcing mesh and reinforcing bar.
- Minimised bit binding against reinforcing bar – increasing operator safety.
- Easily drills through all typical steel decking plate including Bondek®.
- Reduced vibration minimising operator fatigue.
- Extremely hard wearing for long tool life.
- Triple fluted for improved dust extraction.
- Asymmetrical five cutter head on a select range of sizes in SDS Max.

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.
