What is an NC spotting drill?

An NC spotting drill (also referred to as a NC spot drill) is a precise drill that features a small cutting depth, typically around the height of a drill point. NC spotting drills are intended mainly for pre-drilling an accurate location and to ensure precise and fast subsequent drilling operations without guide bushings, especially on CNC machines. Typically, the NC spotting drills have a 90-degrees point angle.

What is the difference between TiAlN and AlTiN coatings?

The main difference between titanium aluminum nitride (TiAlN) or aluminum titanium nitride (AlTiN) coatings is the content of aluminum which is not above 50% with reference to TiAlN, and more than 50% in AlTiN. The dominating metallic element is written first in the coating formula.

Does the MULTI-MASTER family include hole making tools?

The Multi-Master family includes heads with a point angle of 60°, 80°, 90°, 100°, 120° and 145 unintended for chamfering only. The heads are suitable for spot drilling, countersinking supplemented by center drilling heads.
