Design and Specifications of Straight Drills
Ângulo da ponta da broca
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.
- Desenho da flauta
The flute design influences chip removal and cooling during drilling. Straight drills typically have helical flutes that enhance chip evacuation and reduce heat buildup.
- Tipos de haste
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.
Comprimento total
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.
Revestimento e 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
-
Seleção de materiais
The manufacturing process begins with selecting the appropriate material based on the drill's intended application. Common materials include HSS, carbide, and cobalt.
-
Forjamento e moldagem
The material is forged and formed into the desired shape, creating the drill's body and flutes. This process ensures the drill's structural integrity and initial geometry.
-
Tratamento térmico
Heat treatment processes, such as annealing and tempering, enhance the drill's hardness and toughness. This step is crucial for achieving the desired mechanical properties.
-
Retificação e afiação
The drill's cutting edges are ground and sharpened to precise angles, ensuring optimal cutting performance. This step involves using specialized grinding machines to achieve the desired geometry.
-
Aplicação do revestimento
Coatings such as titanium nitride or diamond are applied to the drill's surface to enhance its hardness and reduce friction. This step improves the drill's lifespan and performance in demanding applications.
