Selection of carbide drill bit considerations

use carbide drill, the first need to consider the size of precision drilling. In general, the smaller the aperture to be processed, its tolerance is smaller. Therefore, manufacturers usually arix core drill bit holes to be processed according to the nominal diameter of the drill bit for classification. In the above four types of carbide drill, solid carbide drill highest precision (φ10mm solid carbide drills tolerance for 0 ~ 0.03mm), so it is the best choice for high-precision machining holes; welded carbide drill or replaceable carbide drill crown tolerance range is 0 ~ 0.07mm, generally more suitable for hole machining accuracy requirements; installation carbide indexable insert carbide drill bits are more suitable for heavy roughing, Although its processing cost is typically lower than the other several bits, but its precision is relatively low, the tolerance range is 0 ~ 0.3mm (depending on the bit aspect ratio), it is generally used for hole machining accuracy is not required , or require subsequent finishing hole.

The classification of carbide drill bit

Carbide indexable insert drills: Install carbide drill bits indexable insert drills processing aperture range is very wide, processing depth range of 2D ~ 5D (D for diameter) can be used lathes and other rotating machines. Welded carbide drill: welded carbide steel drill bit is firmly welded body made of a hard metal crown. This self-centering drill blade geometry type, small cutting force, for most workpiece materials can achieve good chip control, machined hole surface finish, dimensional accuracy and positioning accuracy are high, do not have to follow-up fine processing. The electroplated core drill bit uses internal cooling method can be used for machining centers, CNC lathes or other high rigidity, high speed machine. Replaceable carbide drill crowns: the crown replaceable carbide drill bit in recent years to develop a new generation of drilling tools. It consists of solid carbide steel drill body and replaceable crown combination, compared with welded carbide drill, the machining accuracy comparable, but the crown can be replaced, thus reducing processing costs, improve drilling productivity.
