Description

ONYX TAP -for tapping a wide range of materials up to 28Rc hardness. CNC Styleenchances chip evacuation and cutting fluid flow to the cutting teeth for reduced friction, heat and galling. Also reduces contact between the tap and the workpiece. Spiral Point Tapsare designed for effcient tapping of through holes and blind holes with adequate depth for chip accumulation at the bottom of the hole. The shearing action of the point provides freer cutting action and ejects the chips ahead of the tap, eliminating chip evacuation problems and chip damage to the threads. Shallower flutes also result in greater tap strength, allowing for higher cutting speeds. Steam Oxide over Nitrideincreases wear resistance, reduces friction, reduces galling and chip welding, improves chip flow and increases tap lubricant retention.NOT RECOMMENDED FOR NON-FERROUS MATERIALS.Country of OriginUSAWarning-Proposition 65- For Californian Users onlyWARNING:This product contains a chemical known to the State of California to cause cancer or Birth defects.For more information go towww.P65Warnings.ca.govThread Standard NCFlute Count (NOF) 2Thread Size u200e#4 – 40Cutting Edge Material HSSThread Diameter Size (TDZ) #4Tool Type General Purpose TapThreads per Inch (TPI) 40Thread Cutting Part Length (THL) 5/16″Thread Tolerance Class (TCTR) H2Flute Type StraightUsable Length (LU) 5/16″End Shape Spiral PointOverall Length (OAL) u200e1-7/8″Style PlugChamfer PlugMeasurement Type Machine ScrewCoating Steam Oxide Over NitrideSeries/List # 2101
