English term or phrase:Drill diameter points to type of drill
I'm translating into Italian. Could you please explain the meaning/provide a synonym for "points to"??
Drill diameter points to type of drill
One of the first things to be established when choosing a hole-making tool is whether an indexable insert drill or a regrindable drill should be used. The diameter of the hole is the first factor. Indexable insert drills cannot be used for small diameter holes (smaller than 12 mm) so these applications need solid or brazed cemented carbide drills.
Small-diameter holes Solid cmented carbide drills, such as the XXX, are available in different versions, covering a diameter range from 1.5 to 20 mm.
Where it is possible to machine at high spindle speeds the properties of cemented carbide should be utilized in order to achieve increased productivity. When the stability of the set-up is really poor, to the extent that it puts the relaibility of the carbide drill at risk, a high speed steel drill can be an alternative choice
