Finally, no more shelf support

I tried several anchors solutions, but this is so simple.
By means of a drilling template are eg drilled in shelves on the bottom at an angle holes. Then screw and finished without shelf supports or anchors. The board can be freely positioned (an attack angle left and right ensures the right angle).
Excellent for repairs at end parts of cupboards, drawers and tables thanks to concealed holes inside. Also surface compounds such as picture frames are easy.
Important is a high speed when drilling due to the burr on slant-hole.
