90° GoldMax™ Weldon Shank Countersink
- HMT GoldMax™ Countersinks are specially coated for increased tool life, Standard 19.05mm Weldon shank for use in all standard magnet drills.
- GoldMax™ coating keeps countersinks sharp much longer than standard HSS tools.
- Save money with longer-life tooling.
Best Practice Advice while using this item
- Follow guidelines to set correct RPM speed.
- Incorrect RPM can lead to poor life or tool breakage.
- Apply firm, steady feed pressure throughout the cut.
- Avoid lateral movement or tilting which can cause damage to the tool
- Ensure regular application of quality cooling lubricant, especially when drilling thick or hardened materials
- Hardened or heat-affected materials may require higher torque, reduced RPM and feed rates and extra coolant
- Ensure a debris-free surface of sufficient steel thickness for strong magnet hold when Magnet Drilling
- Use at the highest available Gear setting (for maximum torque)
- Best countersinking results are achieved using a variable speed drill that allows the correct speed to be set .
- Piloted Countersink Bits (like the MultiSink) will significantly increase countersinking performance preventing movement of the countersink whilst drilling
