Q: What speed should I run my Countersink at
The number one cause of blunt countersinks we see is them being used at too high a speed, particularly in single speed Magnet Drills only intended for drilling. As a rough rule of thumb Countersinks should be used at around 1/3 the speed you will drill a hole of the same diameter. The reccomended RPM for countersinking each diameter for different material grades can be seen in the Best Practice RPM guide
Q: Can I use my impact wrench with VersaDrive Countersink Bits
VersaDrive Countersink bits can be used up to 16.5mm or 5/8" with an impact wrench for light duty work and deburring. Beyond this diameter impact wrenches or drivers have too high an RPM for Countersinking which generally requires much slower RPM speeds
Q: Which Lubricant do you recommend for Countersinking
Speedlube is generally the best all purpose lubricant, for fast, convenient and accurate aerosol application ensuring coverage inside the hole as well as on the tool. However our BioCut paste is very popular and efficient lubricant for dipping the tool directly into the tin. It’s also great for minimising run off or mess, on painted surfaces or other sensitive applications where run off is to be avoided. Aeropaste can be used if working in applications such as Overhead where a fluid lubricant will run off. Finally BioCut Blue cutting fluid works particularly well with harder materials or difficult applications and is ideal forfor direct application onto the tool and into the hole when working on flat surfaces
Q: Can I countersink Stainless Steel
Yes, but you should reduce the RPM accordingly and use increased lubrication
Q: Can I countersink Hardox and Wear Plate materials
High speed steel tooling is not recommended for Countersinking Hardox and other wear plate materials due to the extreme surface hardness. Tungsten Carbide and specially coated tooling like the Ultra Coated TCT MultiSink.
Q: Can I countersink Laser or Plasma Cut holes
Yes, but you should reduce the RPM accordingly and use increased lubrication and feed pressure. Reduced tool life should be expected due to the heat hardened surface, and probable rough edges of the hole causing uneven cutting and wear
Q: Why has my countersink gone blunt
Typically speaking if the Countersink has blunted sooner than you would have expected it to, the typical cause is using too high an RPM for the particular application causing the tool to wear and blunt prematurely. When used at recommended RPM and torque limits and all best practice is followed, you should expect excellent tool life.
