Step Drill Bit Unibit

Description

• A step drill bit is a type of drill bit used for drilling holes of different diameters with a single bit.
• It has a conical shape with stepped increments, each step representing a different hole size.
• The numbers (6, 8, 10, 12, 14, 16) engraved on the bit indicate the diameter in millimeters for each step.
• For example, the smallest step drills a 6 mm hole, the next step an 8 mm hole, and so on, up to 16 mm.
• This coating reduces friction and heat build-up, increasing the tool’s lifespan and making it more efficient.
• Sheet Metal Work – Step drill bits are ideal for thin materials like sheet metal, aluminum, and plastics.
• Electrical Installations – Electricians often use them to enlarge holes in switchboards or junction boxes.
• DIY & Workshop Projects – Handy for enlarging or de-burring holes without needing multiple drill bits.
• Agriculture/Repair Work – Can be used to make holes in machinery panels, pipes, or enclosures.
• One bit can drill multiple hole sizes.
• Creates clean, round holes with less risk of tearing thin materials.
• Can also deburr the edges of the hole.
• Saves time since you don’t need to change bits for different sizes.
