RS PRO Drill Bit Set, HSS-E Cobalt, 19 Pieces

RS PRO HSS-E Cobalt Drill Bit Set. RS PRO brings you this outstanding drill bit set made from HSS-E cobalt alloy for high performance drill bits.
A great set of the most commonly used diameters.
High-speed steel (HSS) drill bits with 5% cobalt content provide excellent heat resistance even in the absence of sufficient cooling.
The addition of cobalt to the cutting material allows this drill bit to be used in high tensile strength materials up to 800 N/m2.
With a 135° non-slip split point, it is ideal for precise centering and is manufactured to DIN 338 for high precision tolerances and geometric accuracy.
Typical Applications: Cobalt bits offer faster cutting speeds and longer life when drilling high-strength metal materials such as stainless steel, carbon steel, cast iron, titanium alloys, and even carbon fiber composites.
Features and Benefits. % Cobalt High Performance HSSE-E Drill Bit.
High temperature strength without the need for significant coolant 135° non-slip split point for accurate centering Direct drilling without the need for pre-centering or drilling pilot holes Faster cutting and longer life than regular HSS drill bits 0.5 mm increments. Frequently Asked Questions Q. What does jobber mean? A. The word jobber refers to the length of the drill bit.
This generally means that the overall length of the drill bit itself is very long relative to its diameter.
For example, mechanical drill bits have very short flute lengths, which means that their overall length is also significantly shorter.
Q. What is the difference between HSS-E and HSS? A. HSS drill bits are suitable for most drilling applications and can withstand high temperatures.
It is commonly used for drilling a variety of metals.
HSS-E drill bits are capable of high-speed cutting at high feed rates and offer longer life than standard HSS drill bits.
