of the circular hole disc cutter for woodworking.

With the well-known circle, hole, G-I © ckansehneidern etc »

where only © in holes up to a certain size

can be drilled or cut out, you are

not able to drill larger holes without a guide

to be made with the help of a twist drill

a guide was therefore made, so that now too

larger holes can be cut,

But these have the disadvantage that as a result of the leadership

through the twist drill and if it is clamped the

the cut-out disc cannot be pushed off,

because she was still sitting too strictly in the leadership

The machine must be switched off and the disc from the

Leadership to be solved.

If the solution is easier, however, there is a risk

that the disk is thrown out with force "

According to the invention, these disadvantages are avoided in that the cutting knives are radially arranged by means of knife holders extending slots of a flange disk are arranged adjustable and lockable, d ^ B a central one guide bolt axially displaceable against a spring, which has a tip »

The guide pin is printed on the workpiece before the knife attacks, so that an exact guide is available is. When cutting, the guide pin now presses the disc to be cut out firmly onto the surface, which causes rotating or ejecting the disc is excluded.

The cut-out sheet remains in the workpiece and a mtßx operation can be carried out immediately without having to stop the MaSCh * «β«

The cutting knives are shaped in the construction, have no cupboard, but are ground-ground so that proper cutting and ejection of the chips is possible. Cut out slices are for all kinds of purposes reusable *
