RS PRO 25-Piece Twist Drill Bit Set for Metal, 13mm Max, 1mm Min, HSS-G Bits

RS PRO offers this exceptional Drill Bit Set made from HSS coated in Titanium for high-performance, offering more resistance than regular HSS bits. It contains a great selection of the most commonly used diameters from 1 mm to 13 mm in 0.5 mm increments. These High-Speed Steel (HSS) with the Titanium coating are constructed from a single piece of high-speed steel, thus reducing breaking and blunting under heat or stress. The coating gives the bits a very high surface hardness to help penetrate tough materials Manufactured in accordance with DIN 338 for high precision tolerances and geometric accuracies.

HSS-TiN coated bits are highly corrosive resistant and the coating allows for a significant reduction in frictions between the bit and workpiece. The drill bits are suitable for non-ferrous metals, which include aluminium, copper, brass, zinc and iron. It can be used for drilling applications involving plastic, wood and masonry however, the performance is affected.

The shaft is equal to the diameter of the drill for low breakages

A. 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.

A. 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.

25 pieces from 1 mm to 13 mm with 0.5 mm increment bits.
