Designed and developed from feedback from engineers in workshops. TTP Hard Drills:
Drills harder metals where a normal HSS drill bit can not come close
TTP HARD DRILL BITS have been designed for the Easy and Effective drilling of Metals including the Harder Alloys. Manufactured from Tungsten and Molybdenum for increased Hardness and with Cobalt added to ensure superior heat resistance these drill bits are Guaranteed to perform in the most demanding of Applications.

Drilling Steel - An Easier Way
Our cobalt drill bit sets are designed to drill through the toughest and hardest of abrasive materials, they are ideal to use for drilling into stainless steel, titanium, cast iron, spot welds and leaf springs.
Tungsten and Molybdenum make the drill bit incredibly hard, with an abrassive quality, TTP HARD cobalt drill sets have superior heat restistance.
Cobalt bits are made of cobalt steel which makes them hard enough to bore through tough hard metals such as stainless steel, chromed steel. Cobalt steel also makes the bits dissipate heat rapidly which is a prime consideration when cutting metal. Titanium bits are coated in a titanium ceramic material over a high-speed steel. The coating makes them hard, long lasting bits, and the titanium makes them dissipate heat well. Titanium is suitable for wood, plastic and most metals, although COBALT is a better choice for stainless steel and harder steels.
Cobalt drill bits and titanium bits hold their sharpness for a long time. However, titanium bits cannot be sharpened unless you grind off their coating in the process. The shank of a sharpened titanium bit will retain its coating but the point will be steel only and the drilling effectiveness will degrade.
Cobalt bits take a sharpening many times since they are made of cobalt steel throughout the bit. As a result, cobalt bits remain sharper longer than titanium bits. While it maintains its original strength through many sharpenings.
