## Long description

UN Combi Box 3–10 mm drill bit set includes twist drill bits in standard incremental sizes from 3 mm to 10 mm (3, 4, 5, 6, 7, 8, 9, 10). Designed for general-purpose drilling in metal, wood and plastic, this assorted set provides a range of small-to-medium diameters suitable for workshop tasks, routine maintenance and DIY projects. The bits are supplied in a compact combi box that keeps tools organised and easy to retrieve.
Advantages
The set offers a wide span of commonly used diameters in one package, reducing the need to purchase individual bits. Twist drill geometry ensures compatibility with standard drill chucks and straightforward cutting performance across different materials. The combi box packaging provides orderly storage, clear size identification and portability for use at a jobsite or in a home workshop.
Suitable for
 Drilling metal sheets, pipes and light structural components
 Creating holes in wood for joinery, fittings and dowels
 Working with plastics, composites and synthetic materials
 General maintenance, repair and DIY tasks requiring multiple hole sizes
Key specifications
 Type: twist drill bits for general-purpose use
 Diameter range: 3 mm to 10 mm in 1 mm increments (3, 4, 5, 6, 7, 8, 9, 10)
 Material compatibility: metal, wood, plastic
 Packaging: combi storage box for organised transport and access
 Intended use: small-to-medium hole diameters for workshop and DIY jobs
How to use
Select the appropriate drill bit size for the hole required and secure it in a compatible drill chuck. Use the correct drilling speed and feed for the material: lower speeds and steady pressure for metals, higher speeds for wood and plastics, and consider pilot holes for larger diameters. Keep the bit perpendicular to the workpiece where a straight hole is needed, and apply cutting fluid or lubricant when drilling harder metals to extend bit life. After use, clean swarf from the flutes and return the bit to its labelled slot in the combi box.
Usage recommendations
For best results, match drill speed to material, use appropriate clamping for the workpiece, and replace worn or dull bits to maintain hole quality and safety. Use protective equipment such as safety glasses and gloves when drilling.
