Just as showing your mettle is about bravery and strength of character, the metal that goes into drill bits is an important characteristic to look for. Standard bits are typically made of High-Speed Steel (HSS) which is hard and resistant to wear. HSS can also tolerate higher levels of heat. This is an essential feature to have as the friction generated when drilling is obviously considerable. Drill bits made of inferior quality metals will quickly lose their edge as they get hot. In the end, you’ll have to replace them more frequently and ultimately this results in poorer quality holes.
The point of standard drill bits is 118°. These are best for drilling materials such as wood, plastic, and softer metals. With more expensive drill bits such as the M2 set, you’ll see that the geometry is slightly different and they have a finer point. This enables the tip to cut into the material faster. For harder materials, the bit will have a flattering point, normally 135°.
