When creating a drill bit collecting, it’s a good idea to build up a basic set of the bits that should serve for the most DIY tasks. This includes universal twist drills for wood, metal and plastic, and a set of TCT masonry drills for brick, block, concrete and mortar. For more sophisticated material, you will require drill bits that are larger or designed for a specific purpose. Since good quality drill bits can be expensive, it’s crucial to keep your bits in a case rather than letting them roll around loose in a toolbox. Furthermore, cutting edges might be damaged if the drill bits are stored incorrectly. In addition, it’s vital to keep your drill bits sharp by sharpening them occasionally. Do not wait until they become entirely blunt.
Twist bitsTwist drill bits are the most common drilling tools used with a hand or electric drill. The front edges of the drill bit cut the material, and the spirals along the length remove debris from the hole. Twist drill bits can be used on timber, metal, plastic, etc. These drill bits are frequently made from these materials:
- High-speed steel for drilling most types of material.
- Carbon steel for drilling wood.
- Twist drill bits are can also be coated with titanium nitride (TiN). This golden coating increases the hardness of the drill bit and is used for drilling metal.
