RS PRO Drill Bit Set, HSS, 19 Pieces

Drill bits 1 to 10mm, 0.5mm increments. RS PRO 19-piece HSS drill bit set. From RS PRO, this outstanding drill bit set is made from HSS with a titanium coating for high performance and is more durable than high carbon steel bits.
This excellent set includes the most commonly used diameters from 1 to 10 mm in 0.5 mm increments.
This high speed steel (HSS) drill bit is manufactured from a single piece of high speed steel, reducing breakage and crushing caused by heat and stress.
The titanium coating reduces friction in the material, extending the life of the drill bit by over three times compared to standard HSS bits.
Manufactured to DIN 338 for high precision tolerances and geometric accuracy.
Typical Applications: HSS bits have a partially ground tip and are suitable for cutting non-ferrous metals such as aluminum, copper, brass, zinc, and iron.
It can also be used for drilling plastic, wood, stone, etc., but performance will be affected.
Features and Benefits. 19-piece HSS drill bit set Titanium coating to reduce friction Heat treated to HRC 60 → 66 Split point: 135° Shaft equal to drill diameter reduces breakage Cuts faster than regular high carbon steel bits and lasts longer Heavy duty steel case with molded hard insert to store the drills. 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 HSS? A.HSS (short for High Speed Steel) is a standard steel for drill bits because of its excellent heat resistance when operating at high speeds.
A typical drill can spin at up to 500-700 rpm, which creates a significant amount of heat buildup due to friction.
This is undesirable when working with wood or plastic.
