Bosch HSS-G Metal Drill Bit, (Pack of 5)

Metal drill bits, also known as twist drill bits, are specialized cutting tools designed specifically for drilling holes in metal surfaces. They are widely used in industries such as manufacturing, construction, automotive, and metalworking, as well as for DIY projects.

• Geometry: Metal drill bits have a spiral or helical flute design with a sharp, pointed tip. The flutes help to remove chips and debris from the hole during drilling, while the pointed tip facilitates accurate positioning and starting of the hole
• Size and Diameter: Metal drill bits come in a wide range of sizes and diameters to accommodate different drilling requirements. Standard sizes range from fractions of an inch to several inches in diameter, with metric sizes also available for international applications
• Application: Metal drill bits are specifically designed for drilling into metal surfaces such as steel, aluminum, brass, copper, and cast iron. They are capable of drilling precise, clean holes with minimal burring or deformation of the workpiece
• Coolant: When drilling hard metals or conducting prolonged drilling operations, it's common to use cutting fluid or lubricants to cool the drill bit and workpiece, reduce friction, and prolong the life of the tool
