Pilot drill TTD180E - 180°

TTD180E the pilot drill with reinforced shank for centering and drilling on surfaces that are not perpendicular or irregular, concave, convex or with other shapes. The tool has a point angle of 180 °so as to allow drilling in a very wide range of inclinations and shapes.
In the standard version the TTD180D drill is supplied for a depth of cut 3.5 times the nominal diameter, in order to permit optimal positioning and guidance of any subsequent drilling.
The geometry of the tool was created with innovative grinding systems, taking care of surfaces and finishes in addition with a modern, high-performance coating. Even the TTD180E pilot drill, like the MTB27E, has an optimized geometry to increase the tool life in machining stainless materials, consequently it maintains these expectations even in less tough steels.
The drills are available ex stock starting from diameter 0.8 mm up to diameter 6 mm in sequences of 0.05 mm up to diameter 3 mm and then in sequence of 0.1 mm.
The diameters are supplied standard with a tolerance m5 (from> Ø 1 mm to <= Ø 3mm = + 0.002 / + 0.006 mm and> = Ø 3mm to <= Ø 6mm = + 0.004 / + 0.009 mm) For the subsequent drilling of difficult materials we suggest the high performance drills TTD206E, TTD212E and TTD218E for those who can take advantage of the internal lubrication cooling (through the spindle) or the TTD203 and TTD207 drills with the classic external lubrication cooling.
