HMT Tungsten Carbide MultiSink ULTRA Coated 40mm, 90°

The Ultra coated MultiSink and Weldon Countersink offer increased wear resistance and long-life performance whilst countersinking the most challenging applications, including materials like Hardox, Inconel and Armor plate.The MultiSink is a worldwide unique new Combination Countersink Tool designed & developed by HMT for use with Magnetic Drills.Innovative combination countersinking toolSave time completing countersunk holesSuitable for holes 16mm and abovePilot feature gives a precise, concentric fit for excellent performance100mm Length19.05mm (3/4") Weldon Shank90 Degree point angleCountersink starting diameter = 14mmThe extreme hardness and resistance of wear plate makes machining it extremely challenging.Good results are dependent on the right setup - including high torque/slow speed, geared Magnet Drills, such as the VersaDrive® V125T, and correct lubricationFor predrilled holes the MultiSink should always be used with a pilot to avoid damageWhen used for multiple operations eg Drilling then Countersinking, the correct RPM should be used for each separate operationConstant coolant application is advisable to carry away any heat generated by cutting, as heat build up can cause work hardeningDo not allow the countersink to vibrate over swarf while cutting as this will cause chatter, ultimately causing the cutting edge to chip & blunt
