Design and Specifications of Straight Drills
Drill Point Angle
The drill point angle determines the shape of the cutting edge and affects the drill’s performance. Common angles include 118 degrees for general-purpose drilling and 135 degrees for harder materials.
- Flute Design
The flute design influences chip removal and cooling during drilling. Straight drills typically have helical flutes that enhance chip evacuation and reduce heat buildup.
- Shank Types
Straight drills come with various shank types, including straight shank, taper shank, and reduced shank. The choice of shank type depends on the drill chuck and application requirements.
Overall Length
The overall length of a straight drill affects its reach and stability. Longer drills are used for deep hole drilling, while shorter drills offer greater rigidity and precision.
Coating and Material
Coatings such as titanium nitride and diamond enhance the drill’s performance and durability. The choice of material, such as HSS, carbide, or cobalt, affects the drill’s cutting ability and longevity.

Manufacturing Process of Straight Drills
-
Auswahl des Materials
Der Herstellungsprozess beginnt mit der Auswahl des geeigneten Materials für die vorgesehene Anwendung des Bohrers. Zu den gängigen Materialien gehören HSS, Hartmetall und Kobalt.
-
Schmieden und Umformen
Das Material wird geschmiedet und in die gewünschte Form gebracht, wodurch der Bohrerkörper und die Spannuten entstehen. Dieses Verfahren gewährleistet die strukturelle Integrität des Bohrers und seine ursprüngliche Geometrie.
-
Wärmebehandlung
Wärmebehandlungsverfahren wie Glühen und Anlassen erhöhen die Härte und Zähigkeit des Bohrers. Dieser Schritt ist entscheidend für das Erreichen der gewünschten mechanischen Eigenschaften.
-
Schleifen und Schärfen
Die Schneiden des Bohrers werden geschliffen und auf präzise Winkel geschärft, um eine optimale Schneidleistung zu gewährleisten. In diesem Schritt werden spezielle Schleifmaschinen eingesetzt, um die gewünschte Geometrie zu erreichen.
-
Anwendung der Beschichtung
Beschichtungen wie Titannitrid oder Diamant werden auf die Oberfläche des Bohrers aufgetragen, um seine Härte zu erhöhen und die Reibung zu verringern. Dieser Schritt verbessert die Lebensdauer und Leistung des Bohrers bei anspruchsvollen Anwendungen.
