Solid carbide drills - the specialists for drilling holes in metal
TOSAG stocks a wide range of solid carbide drills. This includes different lengths, drilling depths, diameters and shank sizes. The range of diameters extends from drills with a diameter of 1.0 mm to 20 mm, with numerous gradations. This means that the right solid carbide drill bit is available for every application.Properties and possible uses of solid carbide drills
Compared to other metal drills, such as those made from HSS, solid carbide drills have a number of special features and advantages. First and foremost, this includes the high positioning accuracy, which is made possible by the rigidity of the drill bits. This is an advantage for precise series work, as is the case in industrial production. Accordingly, the solid carbide drills also have good centering and guiding properties.Most other metal drills suffer from wear. Solid carbide drills, on the other hand, are robust due to their hardness, which also allows higher cutting speeds with more feed. This in turn ensures shorter machining times per operation. Another special feature of solid carbide drills is the short chips that are produced during drilling. This even applies when drilling in tough or soft materials, which otherwise tend to form long chips.
Solid carbide drill bits are suitable for a wide range of materials. They are primarily used when drilling in cast iron, aluminum alloys, graphite, glass fiber reinforced and abrasive materials. Solid carbide drills can also handle hardened materials.
Solid carbide drills with AlTiN coating
The TOSAG range also includes solid carbide drills with AlTiN coating. AlTiN is the abbreviation for an aluminum-titanium-nitride coating. This coating makes the drills particularly resistant to oxidation and heat. Thanks to these properties, solid carbide drills with AlTiN coating allow even higher cutting temperatures and higher cutting speeds. Solid carbide twist drills with AlTiN coating and internal cooling are mainly used for machining very hard materials above 1,300 N/mm². These are, for example, stainless steel and special steel or cast iron. These drills allow application temperatures of up to 900 degrees Celsius during operation.Solid carbide drills with and without internal cooling
Solid carbide drills are available both as twist drills with internal cooling and as regular drills without internal cooling. Twist drills without internal cooling are suitable for all standard stationary drills and similar systems. Twist drills with internal cooling, on the other hand, are predestined for use in industry, for example on CNC machines and similar systems with a connection for internal cooling.The solid carbide drills with internal cooling allow automatic cooling during the drilling process. On the one hand, the drill itself and the workpiece are cooled. On the other hand, the cooling flux helps to transport chips out of the drill hole and also ensures controlled chip breaking.
These solid carbide drills with internal cooling enable a significant increase in tool life and high material savings. Higher feed rates are possible during machining and the tool life is increased. This makes these drills the right choice for mass production and industrial use. The properties of solid carbide drills with internal cooling increase productivity.
