The Right Tool at the Right Time Forming Taps Metric Coarse Range

Features & Benefits Material Manufactured from premium grade High Speed Cobalt (HSS-E) for: ▪ Increased hardness and toughness ▪ Improved edge strength ▪ Longer tool life Surface Treatment Titanium Nitride (TiN) coating reduces friction, resulting in longer tool life; a bright finish option is also available. Flute Geometry and Chamfer The thread profile generates low torque. This not only ensures a smooth surface finish on the completed thread but also promotes longer tool life. Oil grooves on the E294 facilitate the flow of coolant to the machining area. Available with: ▪ Chamfer form E for...

Threading with taps Flow of material when forming a thread The tapping hole size depends upon the material being drilled, the cutting conditions selected and the condition of the equipment being used. If material is pushed up at the thread entry by the tap and/or the life of the tap is too short, select a slighly larger drill diameter. If on the other hand the profile of the thread formed is insufficient, then select a slightly smaller drill diameter. Drill diameters for cold forming taps Recommendation table Drill diameter can be calculated from: D = D nom - 0,0068 * P * 65 D D nom P = Drill...
