Diamond drilling is an effective drilling technique that can make clean, precise holes through the sturdiest of materials. To ensure proper and safe use of the technological equipment and to produce results of the highest caliber, this is a specialist service that should only be performed by qualified professionals. Continue reading to discover more about diamond drilling’s various applications.


Diamond Drilling Northampton enables precise hole drilling through almost any material, including reinforced concrete, stone, metal, and even concrete. Diamonds, the world’s strongest naturally occurring material, are used in the drill bit and are responsible for this strength. Diamond drill bits also have a hollow design that allows water to be pushed through to keep the drilling tip cool and reduce dust distribution, which makes them suitable for limited locations.


A variety of holes can be made by diamond drilling, all of which will be exact and well-formed. With the use of our equipment, we are able to create holes with a diameter ranging from 12 mm to 650 mm, and stitch drilling—drilling multiple overlapping holes—can be used to create larger openings.

Diamond drilling can be used to cut through a variety of materials, despite typically being used to drill through concrete. Diamond drilling is ideal for an astounding range of operations, including those that are underwater, from glass and tiles to reinforced concrete and masonry.

This technique decreases the possibility of chipping and cracking because it is non-percussive and causes only slight vibrations, which makes it ideal for situations where the rest of the structure needs to be maintained.


In many different types of building projects, diamond drilling is employed. Its widespread use can be attributed to a number of desirable characteristics, including: – Precise, neat, high-standard drilling – Capable of cutting through extremely tough materials

  • Less chance of chips, cracks, or debris since non-percussive drilling produces little dust – Much quieter than other techniques – can be employed in a number of settings, including undersea and tight spaces.
  • On the other hand, the smaller the torsion, the steeper the groove, and the harder it is for chips to be discharged. The greater the twist, the longer the distance; the lesser the twist, the shorter the distance. In other words, the greater the torsion, the longer it takes for chips to be ejected out of the hole, making it easier for chips to clog.
  • The larger the helix angle (the stronger the helix), the sharper the cutting edge, and the better the sharpness, which reduces the cutting resistance (cutting torque). However, since the strength of the cutting edge is low, chipping and chipping are likely to occur. 
  • Conversely, the smaller the helix angle (weak helix), the duller the cutting edge becomes and the less sharp it becomes, resulting in greater cutting resistance (torque: resistance in the direction of rotation). However, since the strength of the cutting edge increases, chipping and chipping are less likely to occur.
  • For this reason, select a “strong torsion” drill for relatively soft materials such as aluminum alloys and copper alloys, and a “weak torsion” drill for relatively hard materials such as steel and stainless steel.
  • Next, regarding the helix angle and the chip evacuation performance, in hole drilling, chips are expelled from the inside of the hole to the outside along the helix of the flute.

In line with this principle, a straight edge drill with a helix angle of 0° has a non-twisted flute (not a helical shape), resulting in poor chip evacuation. It is not suitable for deep hole drilling due to its poor drilling performance, but it is an effective drill for relatively shallow hole drilling and horizontal hole drilling where chips are easily discharged. In addition, straight blade drills have a helix angle of 0°, so they are inferior in sharpness, but the strength of the cutting edge is high, so chipping and chipping can be suppressed. It is suitable for drilling holes in steel and hard materials such as castings.
