TTD 203-207 high performance drills
The TTD203 TTD207 drills have been developed for processing difficult materials such as stainless steel or titanium alloys; these drills allow a drilling of small diameters with an amazing performance and precision.
The cutting geometry, as well as the shape of the groove, have been developed to obtain an ideal chip sliding; this allows a safe drilling with material difficult-to-machine. The drill is supplied with a TiALN coating which, in addition to increasing the hardness, protects the cutting edges from excessive wear. The drills are available from stock from 0.8 mm diameter up to 3 mm diameter in 0.05 mm sequences divided into two families depending on the depth of the hole to be made; 3 times the diameter for the shorter ones and 7 times the diameter for the longer ones (catalogue). The diameters are supplied standard with a tolerance h5, from Ø 0.8 mm to Ø 3mm = 0 / -0.004 mm
For those who have the possibility to use internal lubrication, TUSA has developed a specific range of high-performance TTD drill (TTD204, TTD209 and TTD215) with coolant holes.
To guarantee a safe drilling process we recommend to use the pilot drill MTB27, we also always recommend to follow the drilling method and the indicative parameters for drilling with TUSA TOP DRILL. Naturally, customized versions with different diameters and lengths are also available on request. In addition, the company offers a re-sharpening service for TUSA tools, contact us to discuss the best solution for your needs.
