Flap discs types
Flap discs types depending on their constructive features
КЛТ 1 Схематичное изображение КЛТ 1 Flap disc 1

Is used for flat sanding, processing of edges, weld joints of parts and constructions.

КЛТ 2 Схематичное изображение КЛТ 2 Flap disc 2

Is used for processing of hardly accessible areas, flat sanding of parts and constructions.

КЛТ 3 Схематичное изображение КЛТ 3 Flap disc 3

Flap couple increases bigger contact service of the processed tools, that increases removal stock per unit of time.

КЛТ 4 Схематичное изображение КЛТ 4 Flap disc 4

Due to unique flap positioning the flexibility of the flap disc is increased, processing conditions of hardly accessible areas are better.

КЛТ CONTROL Схематичное изображение КЛТ CONTROL Flap disc CONTROL

Missing segments of disc allow control the condition of processed surface during sanding.

Recommendations about safety use
Recommendations about safety use of flap wheels according GOST R 52588-2011
Before starting work you are to check the discs if there is no mechanic damage of the tool.
To use only the machine in running order. Spindle rotation frequency must not exceed number of rotations per minute, indicated on the wheel.
To fix the wheel on machine spindle without slant, to screw it up with specially designed clamp. To be sure that wheel is properly fixed.
НаTo check wheel rotation at idle speed. There should be no hopping or axis displacement when the wheel rotates.
The sanding starts when the wheel is at the max. number of rotations per minute. While working avoid sudden loadings. Put the disc softly at 10-20 degrees to the processed surface.
The backing of the disc should not contact the processed surface.
Keep away all highly inflammable liquids and fuels from the working area.
During work its necessary to follow protective measures:
wear eye protection wear gloves
wear a respirator Its not allowed to use with lubricating fluid
wear hearing protection
