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.
Features & Benefits
Innovative combination countersinking tool
Save time completing countersunk holes
Suitable for holes 16mm and above
Pilot feature gives a precise, concentric fit for excellent performance
3-15/16" Length 3/4" (19.05mm) Weldon Shank 82 Degree point angle Countersink starting diameter = 9/16" The 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 lubrication For predrilled holes the MultiSink should always be used with a pilot to avoid damage When used for multiple operations eg Drilling then Countersinking, the correct RPM should be used for each separate operation Constant coolant application is advisable to carry away any heat generated by cutting, as heat build up can cause work hardening Do not allow the countersink to vibrate over swarf while cutting as this will cause chatter, ultimately causing the cutting edge to chip & blunt
