TTP HARD Drills Bits Are Officially Certified As HARD
TTP HARD drill bits Ltd knew their cobalt drill bits were hard but wanted to know exactly how hard. They commissioned SGS, the worlds leading testing and certification company, to find out how hard they were

Drill bits are available in both Metric and Imperial sizes and can be bought with 'CUT-IT' their own brand of metal cutting paste which has been designed to make any drilling task easier.
Earlier this year Managing director Brendan Kennedy decided to get both their drill bits and their cutting paste tested to see just how good they were. Brendan said, "We commissioned two of the world's leading inspection, verification, testing and certification companies to test our cobalt drill bits for hardness and our cutting paste for its ability to resist extreme pressure."
Their drill bits were sent to SGS who conducted a Hardness check to BS EN ISO 6508-1:2016 using the Vickers testing method. A video was made showing the testing procedure which uses a diamond to indent the drill bit at various points. A hardness rating was then established based on the size of indent made by the diamond. A rockwell hardness of 66 was recorded.
CUT-IT cutting paste was sent to SFS Subsea Fluid Services who were commissioned to carry out and video the Falex Load Test in accordance with ASTM D 3233-93. This is the standard test method for measurement of extreme pressure properties of fluid lubricants.
The test was run with a test load of 1,300lb for 30 minutes, the result was that even under such pressure CUT-IT paste was still lubricating well.
TTP HARD drills are undoubtedly delighted with the results and have videos of both tests along with certifications available online.
