Core Drill Hand Held

Core Drill Hand Held

  • For drilling into concrete to create holes for pipes in sanitary, heating and air conditioning installations.
  • Exceptionally user-friendly thanks to self-explanatory features and controls.
  • Compact, lightweight unit for extremely easy handling.
  • 2-speed gearing for optimum speed and torque.
  • Reset switches are on the machine in case of overload on the electric circuit of the machine switch assembly.
Don’t force drill. Drill slowly, don’t try to put too much pressure on the bit thinking you will cut through the steel. Let the diamond teeth do the work. It is a slow process. Use water to keep the bit cool. Always make sure water reaches diamond tips of bits. Secure with anchors prior to drilling. Careless or improper use of this equipment may result in serious injury. Never allow an inexperienced person operate this equipment. Drilling with diamonds (an abrasive technology), when compared to sds percussive drilling, is the slowest of all cutting methods. Concrete drilling with embedded steel can take many times longer. Have realistic expectations as to the time it requires. When coring through steel always drop to the lowest speed possible. Raise and lower the drill motor multiple times until you have cored through the steel. When cutting steel, the slurry usually changes colour (usually to gray), or the drill motor speed drops. Drop the motor speed down and relax pressure by about 1/ if you don't, the segments may overheat and bend inwards (occasionally outwards), and stop cutting. The barrel may also crack. Some operators reduce water after exiting the steel to redress the blade again, but don't forget to turn the water up again afterwards. We do not reco mm end turning off the water for best results, apply water until the slurry looks like coffee made with a lot of milk. Too much water flow washes away the abrasive slurry which is needed to keep wearing away the segment and keep fresh diamonds exposed. Too little water can cause the diamond segments to overheat clean out the core hole often never undo the stand with the barrel in the hole.. For operator safety, most manufacturers reco mm end drilling over 67 mm be done with the drill mounted in a stand. The bits become dull or “blunt” and need to be redressed if the drilling is slow, the barrel may have glazed up. Redress the bit by reducing the water by half for a few minutes, or by drilling into an abrasive material like limestone, a cinder block or similar. A bit of ajax or builders sand down the hole can also have the same effect - run the drill at a slower speed, with reduced downwards pressure, so that an abrasive paste forms that will sharpen the segments. Similarly, if you are drilling concrete with a high strength (or mpa), or with very hard aggregate in it, the bit may glaze up and need redressing. Do this by reducing the water by half for a few minutes, or by drilling into an abrasive material like limestone, a cinder block or similar. A bit of ajax down the hole can also have the same effect. Be aware, no two coring jobs are ever the exactly the same. Variables include (but are not limited to) – what age is the concrete, what hardness and size of stone was used, the quantity and type of chemicals added to produce harder mpa's, how much steel reinforcing rod will be drilled etc. If excessive vibration or 'snatching' at the core barrel is detected – stop, remove the core drill, remove the core and investigate. Remove any lose material, pieces of cut steel rod etc. When drilling brick walls, wall ties maybe encountered - remove them with pliers. Failure to fix these problems may result in segment damage or loss. If the drill speed is too high, the diamond segment will skip over the grinding surface. This means the core barrel bond will not wear away to expose new diamonds and the cutting edge becomes blunt or glazed over always turn on the water (always use clean water) before turning on the motor. Core drilling tips: ensure there are no gas, power or water lines or any other issues where you are going to drill never stand on a rig to hold it down, as this causes a 'ribbing' effect on the core, and the bit will eventually bind up in the hole the driller's experience in deep coring is essential. The slurry from the cutting of asphalt or concrete is distinct and consistent. As soon as the core barrel cuts through the bottom of the asphalt or concrete into the road base, the slurry coming up to the surface will look different. Watch for the change, and then you will know you are through.
