I will buy the next rotary hammer with a built-in vacuum cleaner for collecting dust
Anyone who has drilled with a hammer drill knows how dust interferes with work when drilling on the ceiling. Yes, and it is not advisable to dust on the walls when finishing indoors. If there is an assistant nearby, you can ask to take a vacuum cleaner and substitute a hose for sucking up dust during drilling. And if you are in a commercial facility and alone?
Some manufacturers in the lineup have dust extraction systems for rock drills. And these are not just rubber or silicone tips that mechanically keep dust from spreading (close the drill). There are full-fledged electric vacuum cleaners, which, when installed, become one piece with a perforator. Let's start the review with simple, air-powered impellers of an electric motor:
Dust extraction system MAKITA 136018-6 for hammer drills HR2650; HR2651
There is a limiter for drilling and adjustment for the outreach of the dust extraction rod. Unfortunately, the attachment is not universal. This is an accessory for a specific range of MAKITA rotary hammers. Cost - 7700 rubles.
The dust is sucked in from the drill site and enters the HEPA filter through the nozzle. A vacuum is formed when the fan impeller of the electric motor is running. The punch body has a hole at the bottom. Through it, air is sucked in. The TM HEPA filter retains up to 99% of all dust and does not get into the electric motor.
This power tool manufacturer also has dust extraction systems:
Dust extraction system DX07 MAKITA 199570-5 for rotary hammer BHR243, DHR243
Designed for cordless rotary hammers BHR243, DHR243. The device also filters dust through a HEPA filter. But it already has a separate electric motor. Powered by a perforator battery. Those. in fact, it is a full-fledged hanging vacuum cleaner. Price: 9870 rub.
Junior model:
But, perhaps, the most affordable model with a dust collection system from this brand is a hammer drill Makita HR 2432
The hole for air intake in this rotary hammer is also located at the bottom of the case. And there is also a special bag for collecting dust. Through a special impeller in the punch body, dust enters the bag, remains there, and the air comes out through the fabric. As in a simple household vacuum cleaner.
The disadvantage of all dust collection systems driven by the impeller of an electric drill motor is that dust suction does not work at low speeds. Makita HR 2432 made high speed - 1000 rpm. The cost of the puncher is 14,000 rubles.
Cordless tools are now becoming more and more popular. And it's not just screwdrivers. Battery model from another brand:
Dust extraction system BOSCH GDE 18V-16 for cordless rotary hammer GBH 18 V 26
This is an analogue of the DX07 MAKITA 199570-5 model. Also with battery power and its own electric motor and a convenient filter. Price: 7500 rubles.
A few more examples of dust collectors-vacuum cleaners from other manufacturers:
TM Milwaukee and other manufacturers have similar systems. You can see prices in online stores here:
But, perhaps, the most affordable for most buyers are simple nozzles for the hose of a construction vacuum cleaner:
Although, something similar can be done with your own hands for 100 rubles:
Vacuum cleaner nozzle from a sewer tee 50 / 50x45 gr. and two cuffs - 50x40 and 50x32.
