The ultimate in accuracy of cut and cleanliness of breakout

  • Armeg Dry Diamond Core Drills offer a quick, clean and economical way to drill soft abrasive materials such as standard facing bricks and concrete building blocks.
  • Dust Relief Slots help the dust escape and not become trapped in between the barrel and material which will improve performance
  • 130mm Throat is designed for deep core drilling, with the ability to core through a standard brick in one action – no need to stop and break out the core
  • Designed with the optimum segment configuration as the segments sit in balance with the body and give relief internally and externally. This results in smoother and more accurate cutting and helps material core removal
  • Laser welded segments create a stronger bond between tip and barrel resulting in increased core durability in extreme drilling conditions
  • Industry segment heights can be as low as 7mm whereas Armeg Dry Diamond Cores are designed with 9mm segments to increase product life.
  • Designed with a high concentration of diamond grit within the segment structure, allowing the Cores to be used on ‘rotary only’ for cleaner exit holes, improved performance and product life

 

Dry Diamond Core Drills can be used in:

  • General concrete
  • Soft bricks
  • Lightweight blocks
  • Natural stone
  • Limestone
  • Ideally suited to lightweight building materials, ordinary facing brickwork and block-work up to 10n/mm2
  • Typical Connection Diagram as follows NB Only the red core drill will be supplied . If you require any of the additional parts please email us at admin@toolvillage.co.uk and we will be happy to provide you with a cost for what is required

 

  • For optimum performance and perfect results use any rotary drill with a minimum drive power of 850 watts. The machine should also be capable of speeds up to 3000rpm and have variable speed control and a slipping clutch.Safety and Operation GuidelinesALWAYS
    • Drill a pilot hole in the wall first with a 10mm masonry bit.
    • Use an 850 watt (minimum) rotary drill with a slipping clutch and variable speed control.
    • Locate the 10mm A-taper guide rod down through the core and push fit the guide rod into the adaptor.
    • Make sure the chuck is tight.
    • Clear the debris at regular intervals, as build-up of dust leads to inefficient drilling and can result in overheating, excessive clutch wear and possible loss of segments.
    • Use the machine between 350 and 3000 rpm.
    • The harder the material and larger the diameter of the core, slower the rpm.
    • The softer the material and smaller the diameter of the core, higher the rpm.
    • Faster rotational speeds do not always mean better material penetration – please refer to the operation speed chart below.
    • Rotate the core drill whenever entering or removing from the hole.
    • Keep the machine level.
    • Reduce pressure if the bit starts to vibrate.

    NEVER

    • Drill concrete.
    • Use hammer action when drilling with a diamond core drill.
    • Force the core – let it do the work. This prolongs the life and reduces the chance of failure.
    • Make long, continuous drilling motions without clearing the debris.
    • Let excessive heat be generated at the drilling edge.


    IF DRILLING WITH SDS PLUS MACHINES

    • Whenever possible use a dedicated dry diamond core drilling machine.
    • While SDS Plus machines can be used, most can only rev up to 1200 rpm which means reduced drive power and slower drilling speeds compared to dedicated dry diamond drilling machines.
    • Using SDS plus machines for dry diamond drilling increases the risk of product damage and exposure to hand arm vibration.
    • Do not use the SDS Plus adaptor with the 117 and 127mm cores.
    • These diameters are beyond the capability of SDS Plus machines – adaptor and machine damage could occur.
    • If adaptors should fail whilst drilling with these cores then they will not be warrantable.

    Tech-Tips

    • It is advisable to drill a pilot hole first with a masonry bit and then core using a guide rod assembled in the adaptor
    • Our 1/2″ BSP Accessories are compatible with all 1/2″ BSP threaded core drills
