How to select cemented carbide bit?
Cemented carbide bit selection is based on the use scenario. Nono sorted out the common use scenarios for you.
1. Used on advanced machining centers
The integral cemented carbide bit is selected. This bit is made of fine-grained cemented carbide material. In order to prolong its service life, it is also coated. The specially designed geometric edge makes the bit have self centering function, and has good chip control and chip removal performance when drilling most workpiece materials.
2. Used on lathes and other rotary machining machines
The cemented carbide indexable blade bit is selected, which has a wide range of machining hole diameter and machining depth range of 2D ~ 5D (D is the hole diameter).
3. Machining center, CNC lathe or other high rigidity and high speed machine tools.
Select welded cemented carbide bit or replaceable cemented carbide crown bit. This kind of bit firmly welds a cemented carbide crown on the steel drill body or is composed of steel drill body and replaceable integral cemented carbide crown. The self centering geometric edge type is adopted, the cutting force is small, and good chip control can be realized for most workpiece materials. The machined hole has good surface finish, high dimensional accuracy and positioning accuracy, so there is no need for subsequent finishing.
What are the types of cemented carbide bits?
Although there are many cemented carbide bits, there are only four basic types: integral cemented carbide bit, cemented carbide indexable blade bit, welded cemented carbide bit and replaceable cemented carbide crown bit.
