Core drills for Diamond drill with micro impact 108

Core drill bit for a diamond drill with micro-impact

On construction sites, you can often encounter high-strength reinforced concrete, drilling which with a regular hammer drill or diamond drill becomes a difficult or time-consuming task.

Or, for example, it is necessary to drill holes in a short time. Specifically for such tasks, diamond drills with micro-impact have appeared on the power tool market.

To ensure high working speed on such equipment, manufacturers of diamond tools produce special diamond drill bits.

The micro-impact system is similar to what is used in conventional drills. Two ratchets have a certain number of teeth, and during rotation they come together and move apart, thus creating a slight impact.

Unlike a conventional drill, where it is not possible to work in impact mode with diamond accessories, a micro-impact drill has several times lower impact force, which only positively affects the processing speed of the material without damaging the drill bit.

Currently, many micro-impact drills are already available on the market, so when purchasing, you should pay attention to the main parameters that affect tool performance:

• Power. This parameter can range from 1.5 kW to more than 3 kW. The more powerful the drive, the larger the diameter of the drill bit that can be used with it. Power also directly affects drilling speed.
• RPM. Diamond drills with micro-impact have higher RPM than conventional ones. The minimum RPM among available models is 1500 rpm, while the maximum reaches up to 3600 rpm. High RPM also positively affects drilling speed.
• Number of impacts. This parameter depends on the number of rotations and the number of teeth on the ratchets. It also has a significant effect on drilling speed. The number of impacts can range from 28,000 RPM to 48,000 RPM.
• Additional features. These include the presence of a dust extraction nozzle, speed modes, the possibility of mounting on a stand, and, most importantly, protection against overload and overheating.

The more functions and better parameters a power tool has, the faster the drilling will be, and the longer the tool itself will last. Very often, craftsmen ask themselves – can any consumables be used on a diamond drill with micro-impact?

Almost any diamond accessory used on hammer drills or diamond drills will also work on micro-impact drills, but with such use its service life will be significantly reduced. Specifically for working with micro-impact, TM "ADTnS" offers 2 types of drill bits:

1. CS-X. This drill bit is designed for drilling holes for sockets and junction boxes. Available in diameters of 68, 72, and 82 mm.
2. RS-TX. This diamond accessory is designed for deep holes with a wide range of diameters from 42 to 200 mm. An excellent solution for making multiple technological holes – for air conditioners, ventilation, water pipes, and much more.

Many micro-impact drills have a special dust extraction pipe, which is especially useful when drilling deep holes, as dust removal becomes more difficult as the drill penetrates deeper.

For drills that are not equipped with dust extraction, TM "Mechanic" produces special attachments called "DrillStream". This device solves the mentioned problem and can be mounted on any micro-impact drill. Depending on the type of mounting hole, there are attachments with M18 or 1 1/4 UNC connections.

In addition to dust extraction, TM "Mechanic" also produces special attachments for convenient centering and initial drilling – "Centrator". Currently, this attachment is available in three sizes: 42/52 mm, 62/72 mm, and 82/102 mm.

On the DISTAR website, you can quickly choose a drill bit for a micro-impact drill in the required diameters, as well as purchase various attachments to simplify the workflow.

In addition to the above devices, extensions for core drill bits are always available, allowing you to make holes of any depth.
