ITC has introduced the GTD2001 and GTS2005 series of taps for the threading of through holes in steel and stainless steel. These spiral point taps are manufactured from an HSSE-PM material that is TiCN coated to improve tool life and performance. With overall dimensions to DIN371/376 and a 6HX tolerance, says ITC, both are capable of delivering impeccable thread quality and form.
GTD2001 is available from M3 to M20 with an overall length from 56 to 140 mm while the through coolant option, available from M5 to M12, will improve chip removal and extend tool life for customers with through coolant machine tools.
The GTD2005 taps are TiN coated with a lubricious layer of chromium carbide carbon specifically for the threading of difficult-to-machine 300 series stainless steels. Like the GTD2001 series, the GTD2005 is available from M3 to M20 with a through coolant option from M5 to M12.
ITC explains that both the GTD2001 and GTD 2005 have an optimal lead-in with a left-hand helix, as left hand helix taps are far stronger and promote improved cutting action.
To complement its through hole tapping ranges for stainless steel, ITC is also offering its GTD2003 and GTD2007 range of taps for the threading of blind holes in stainless steel. The spiral flute blind hole taps are available from M3 to M20 with through coolant taps available from M5 to M12. The ability of through coolant taps to remove swarf from blind holes can improve tool life from three to five times.
