Abstract

The drill bit for drilling holes in wood etc. in preparation for wood screws to be inserted has a shape which essentially corresponds to that of the woodscrew, e.g. a conical shape or a stepped shape. The shouldered conical and stepped contacting part ensure that each drilled pilot hole is ready for immediate reception of required screw size. This eliminates several tool bit changes which have to be carried with conventional bits. The drill shank may be of standard size.

Lösungsolution

Holzschraubenbohrer. ;Wood screw drill. ;

Die Erfindung betrifft einen Bohrer fürThe invention relates to a drill for

Holz schrauben. Wood screws .

Holzschrauben sollen zwei oder mehrereWood screws should be two or more

Teile aus diversen Werkstoffen dauerhaftParts made of various materials are permanent

aneinanderheften. Dazu muß der Werkstoffpin together. For this, the material must

vorgebohrt werden.be pre-drilled.

Solche Bohrungen erfolgen mittels Spiralbohrern mit anschließender Bearbeitung durch Krauskopf zum Versenken des Schraubenkopfes. Such holes are made using twist drills with subsequent machining by Krauskopf for countersinking the screw head.

: Drei Arbeitsgänge sind nötig, um z.B. zwei Stücke Holz mittels Holzschraube aneinanderzuheften. ^: Three operations are necessary, e.g. to remove two pieces of wood with a wood screw to pin together. ^

1.) Dünne Bohrung, in die sich der Gewindeteil der Schraube hineindrehen muß. 1.) Thin hole into which the threaded part of the screw must screw.

2.) Dickere Bohrung, in die der Schaft der Schraube passen muß.2.) Thicker hole in which the shaft the screw must fit.

73..) Krauskopf bohrung, um den Schraubenkopf zu versenken. 73 ..) Krauskopf drilling to countersink the screw head.

: Der Holzschraubenbohrer soll in einem Arbeitsgang eine besonders saubere Bohrung erzielen.: The wood screw drill should be used in one Achieve a particularly clean hole in the operation.

: Der Holzschraubenbohrer besteht aus 1.) zwei parallel oder auch konisch zulaufenden Enden:: The wood screw drill consists of 1.) two parallel or conical tapering End up:

Das dünne für den Gewindeteil der Sahraube;The thin one for the threaded part of the Sahraube;

das dicke für den Schaft der Schraube; 2.) dem Krauskopf;the thick one for the shaft of the screw; 2.) the Krauskopf;

3.) dem Widerlager, damit die Bohrung nicht zu tief wird.3.) the abutment so that the hole does not get too deep.

Beschreibung eines Ausführungsbeispieles Description of an embodiment

Um den Holzsehraübenbohrer auch für nicht versenkbare Schrauben verwenden, zu können, fehlt Iediglich der Krauskopf . ■ '"':Ji"':"^''/^''.'';,i ' . . ' In order to be able to use the wood incense bit also for non-retractable screws, only the Krauskopf is missing. ■ '"' : Ji "' : "^''/^''.'';,i'.. '

Die mit der Erfindung erzielten Vorteile bestehen darin, daßThe advantages achieved by the invention are that

1·) gegenüber den bisher drei Arbeits-· gangen nur noch einer nötig ist, und1) compared to the previous three working only one more is needed, and

2.) daß die Verschraubung we sentlieh sicherer ausgeführt werden kann, weil sich das Gewinde der Schraube exakt in das Material hineindreht und, der Schaft sich nicht zu früh in dem Material festklemmen kann.2.) that the screw connection we sentlieh Can be performed more safely because the thread of the screw turns exactly into the material and, the shaft does not move too early can get stuck in the material.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben: a = Bohrerteii für das Gewinde b = Bohrerteil für den Schaft der Schraube c = Krauskopf ~:
d = Widerlager. ^An exemplary embodiment is shown in the drawing and is described in more detail below: a = drill part for the thread b = drill part for the shaft of the screw c = Krauskopf ~:
d = abutment. ^
