2 Vergnano has a Certified Quality System according to ISO TAPSIn recent years the use of cold Forming taps for tapping processes has increased significantly. Since its introduction, Vergnano has embraced this technology continuously improving and extending its cold Forming tap range. This catalogue summarises the four Vergnano cold Forming tap fa-milies, updated with new sizes and geometries. Research in PVD techno-logy has permitted the development of the new TiH1 coating particularly suitable for cold Forming of light and advantages of Forming taps Thread obtained by plastic deformation of material No chip formation and therefore high process stability and reliability compared to normal cutting process Single tool for both blind and through holes Possibility of threading deep blind holes Higher tool life Higher machining speeds compared to cutting taps Better surface finish on formed thread

3 Better tensile strength of formed thread due to material work-hardening More resistant tap geometry, with lower risk of breakage, due to larger core diameter Ecological tool: lower quantity of tools consumed, no costs for chip disposal and possibility of using minimum quantity lubricationRequirements Larger and more precise drilled hole diameter compared to cutting taps Workpiece material with a minimum elongation coefficient A5 of at least 10% and a maximum tensile strength of 1200 N/mm2 Good lubrication Higher power requirement (100 150%)

4 As compared to cutting tapsTolerance fields Forming taps are constructed with oversize tolerances compared to cutting taps in order to obtain threads which are in tolerance. For internal thread tolerances 6H and 6G, Forming taps with 6HX and 6GX tolerances must be used, respectively.

5 Reliability and A-type Forming tapThe A-type Forming taps are all-purpose taps for both blind and through holes and can be used to machine a wide range of materials. The taps are available in two types of coatings (TiN and TiCN) as well as a vapourised version particularly suitable for tapping soft carbide Forming taps The Vergnano H-type carbide Forming tap is available in a single version (HB80NR). The tap is equipped with an internal coolant channel with radial outlets and can be used to machine a wide range of materials: from steels (including stainless steel) to aluminium alloys.

6 On steel, the increase in tool life compared to high speed steel Forming taps can be up to Forming tap for synchronised tapping The Sincro range taps are designed specifically for synchronous tapping and for high speed machining. They are produced in top quality powder metallurgy high speed steel, HSSK. The reduced thread length compared to standard taps permits tapping of deep holes. A version with internal coolant and radial outlets is also available (BS80NR) for tapping very deep blind and through performance P-type Forming tap The P range is characterised by high tool life and excellent surface finish on the workpiece thread.

7 The taps represent the state-of-the-art in Vergnano technology: powder metallurgy high speed steel HSSK, specially-developed polygon geometry for high performance and optimised PVD coatings with dedicated process parameters and characteristics. The P-type range also includes tap versions with internal lubrication which have an increased tool life and can be used together with ecological minimum quantity lubrication (MQL).65969X6GX6 HXHSSEHSSEHSSEHSSEC (2-3)C (2-3)C (2-3)C (2-3)1,5 x D1,5 x D2,5 x D2,5 x DAAAA88101099111112121414131315151616lll lllllllllllllllllll35-4035-4018-2235-401 8-2235-4015-1830-3515-1830-3510-1510-151 0-1510-1540-4540-4540-4540-4540-4540-451 5-2015-20A82 NA81 NA81A81A81 NA81 NA81 A81 A80 NA80 NA80 A80 A80 NA80 NA80 A80 A82 NA81 NVAPTiN/TiCNVAPTiN/TiCN6GX7 GXTYPES OF HOLEMATERIALCHAMFER FORMSERIESARTICLE LEGENDINTERNAL COOLANTIKZ Axial holeIKZ-R Radial holesLUBRICATIONE EmulsionO OilMQL Minimum quantity lubrication TAP MATERIALHSSE Conventional high speed steelHSSK Powder metallurgy high speed steelHM Solid
