Produktbeschreibung

BB Spotting Drills
60，90，120 degree drill point.
TiN coated HSS
For mild steel and other soft metals.
Manual grinding.
It's not only as a center drill but as a chamfer tool as well.
For accurate spotting on Machines.
Precise drill positioning.
Short lengths and no body clearance make this a very rigid tool.
In order to reduce factors that are not good for machining, such as uneven part surfaces or slightly used drill bits, a simple way to avoid "slipping" is to use a fixed-point drill. The tool is designed to leave a dent on the surface of the part so that the drill bit can be engaged during the drilling process and maintain its correct alignment to prevent the drill bit from deviating from the route.
Geometry
The shape of the spot drill is short and thick, the chip removal groove is very short, and the alloy centering drill with excellent rigidity has better effect. Its drill tip geometry is just enough to drill a shallow hole on the surface of the workpiece; Compared with standard drills, the centering drill has a very thin chisel edge, which can effectively cut the workpiece material.
