Drywall sander (giraffe) Bosch Professional GTR 550

Drywall sander Bosch Professional GTR 550 — a high-performance machine that qualitatively sands walls inside or outside rooms from paint, plaster. Installation power — 550 W. Operating revolutions are set in accordance with the tasks (from 340 to 910 rpm). The backing pad diameter is 215 mm, sanding sheet — 225 mm. The standard version (1.7 m long) weighs 4.8 kg. Supplied in a carrying case with a set of backing pads, a sanding sheet (P180), and cable clips (3 pcs).

Description of drywall sander Bosch Professional GTR 550:

• The Bosch GTR 550 giraffe is designed for high-quality treatment of drywall walls to clean them from roughness, residues of paint or glue;

• The quality of work significantly depends on the surface being processed, selected consumables that differ in abrasiveness, rotation frequency (340-910 rpm) and pressing force;

• For full safety, it is worth inspecting the sander before starting and after completing work and replacing consumables in time; use a construction vacuum cleaner;

• Before replacing one sanding sheet with another, it is worth cleaning the sanding backing pad from construction dust and dirt;

• Several types of backing pads are distinguished for work: 1) soft, which are designed to work out more precise contours, curves; 2) hard — in order to qualitatively prepare walls for painting (sand down irregularities, scrape off old paint);

• The wheel makes it easy to set the required number of revolutions before starting work or in the midst of the working process. Constant electronics ensures high performance both at idle and under load;

• The electronics takes care of the motor's service life, so the mechanism is equipped with a smooth start;

• The machine is equipped with an airflow regulator, which can be used to set 1 of 3 modes: 1) external airflow — for work at high revolutions without the vacuuming process; 2) mixed flows (internal and external) — has average productivity with vacuuming turned on; 3) also mixed flows, which have a low rotation speed, but a high level of vacuuming (the settings are ideal for processing ceilings);

• The wheel makes it easy to set the waste suction power, which is adjusted from level 1 to 6. It is worth starting from a lower position to a higher one in order to establish the optimal option (if too high a speed is set, the machine will bounce too much, it will be difficult to hold in hands);

• By using the brush segment, it will be convenient for the user to work with the sanding machine near edges;

• For convenience, tubes can be shortened or extended, where there are such fixed tool lengths — 1.1 m, 1.7 m, 2.3 m;

• The handle is ergonomic with an insulated surface, reduces the risk of altering the working surface during sanding operations.

Technical features of drywall sander Bosch Professional GTR 550:

• Connects to 230 V mains

• Input power 550 W (nominal)

• The giraffe is equipped with constant electronics, smooth start, selection of optimal settings

• The motor generates constant power with identical revolutions; adds productivity at any rotation speed and choice of airflow mode

• Revolutions are set manually within 340-920 rpm.

• Operating backing pad diameter 215 mm, sanding sheet — 225 mm

• The latter has the following grit sizes: 1) P100 — for processing hard surfaces; 2) P120 — average hardness of putty; 3) P180 — soft or very soft

• A dust extractor is used, the diameter of which is 45 or 35 mm

• The working part features UltraFlexible technology, which consists in safe movement of the tool on working surfaces without damage

• The backing pad with the sanding sheet literally "suctions" to the ceiling, so that it is comfortable for the operator to work

• The segments are sectioned, selected according to the workspaces (has 3 variations). This adds versatility to the work

• 3 lengths: 1) shortened version (without extra tubes) — 1.1 m; 2) standard (with 1 tube) — 1.7 m; 3) extended (2 tubes) — 2.3 m

• Sound power reaches 95 dB (A)
