A comprehensive 25 piece HSS-E Cobalt alloy high-performance drill bit set containing a great selection of the most commonly used diameters. Constructed from High-Speed Steel featuring a 5% cobalt content (HSS-E) enabling increased heat resistance.
Cobalt bits cut faster and last longer when drilling high tensile metal materials, from Stainless Steel, Carbon Steels, cast Iron, Titanium alloy and even Carbon Fibre composite materials and are suitable for use with high tensile strength materials of 800N/m².
The HSS-E drill bits feature a 135° non-slip split point the Cobalt drill bits and are perfect for precision centring. Manufactured in accordance with DIN 338 for high precision tolerances and geometric accuracies.

Direct drilling without the need for prior centring or drilling a pilot hole
Cuts faster and lasts longer than regular HSS drill bits
0.5 mm increments

The word jobber specifies the length of the drill bit. This generally means the length of the entire drill bit itself is significantly longer for diameter it has. As an example, a mechanic drill bit will have a much shorter flute and therefore have a much smaller overall length.

HSS drill bits are suitable for most drilling applications, they are able to stand up to high temperatures. typically used for drilling a wide variety of metals.
