1 Threading Tools Cutting, milling and forming custom-made Chip by Chip to the Top

2 Our Threading Tool Range Threading tools are together with drills, reamers and milling cutters the most important types in the range of STOCK precision cutting tools. The variety of design, together with different thread forms, manufactured in diverse tolerances according to standard or special made, offers a large choice for solving threading problems. The quality of the drilled hole in respect of correct size, roundness, straightness and surface roughness has an eminent influence on the produced thread. To be on the safe side, it is recommended to use STOCK drills for better results. Request our catalogue or contact us for our recommendation for the most suitable tool. 2

For best results the tools are bright finish, steam tempered, nitrided or coated with e.g. TiN, TiCN, TiAlN or/and MoS2 (for better lubrication).

4 Synchronic and universal STOCK Synchro taps CNC controls on modern machine tools have improved the production of threads with machine taps to the extent that spindle rotation and feed are generally synchronised. Conventional length compensation chucks are subsequently superfluous. It can, however, indeed be helpful to apply modern compensation chucks with slight axial movement for machine taps in synchronous applications. Especially for the production of blind hole threads they compensate possible errors. Through accurate tool clamping with small concentricity deviations and synchronous guide the tool life is improved even with considerably higher cutting speeds compared to conventional taps. STOCK HSS-E-PM synchro machine taps with a suitably developed cutting edge geometry and TiCN-coating withstand the high loads resulting from the higher cutting speed and the reversal of the cutting direction. The type Intensiv possesses internal cooling in order to support a reduced friction chip evacuation in the direction of the shank as well as optimal cooling for the production of blind hole threads. Both types, Intensiv for blind hole threads and Produktiv for through hole threads, are geometrically designed so they are suitable for a wide range of materials, i.e. they are universally applicable. Application range: Universal machining of a large material range with tensile strengths up to 1200 N/mm 2 : - nonferrous metals - general steels - stainless and acid resistant steels - cast iron - Titanium and Nickel alloys The suitability for your special material should be tested by machining trials. We gladly advise you! Advantages: - absolutely accurate threads - cutting errors are impossible - no pre-expanding - no pitch distorsion - tool caring machining - optimal chip evacuation - high cutting parameters - long tool life 4

In addition, formed threads generally possess a higher tensile strength in comparison to cut threads thanks to an uninterrupted grain flow and subsequent work hardening. 22
