HSS-porasarja OEM E-500-1225, 25 kpl, koot 1–13 mm

HSS drill set OEM E-500-1225 contains 25 high-speed steel drills in sizes from 1 mm to 13 mm, supplied in an organized case for convenient storage and selection. The drills are intended for general-purpose drilling in metal, wood and plastic, providing a wide size range suitable for workshop tasks, maintenance and small-scale manufacturing. The set simplifies choosing the correct diameter for precise holes and routine repairs.

Advantages

The set provides a continuous range of diameters from 1 mm to 13 mm, reducing the need to buy individual bits. High-speed steel construction offers a balance of hardness and toughness for effective cutting in a variety of materials. The compact case keeps drills sorted and protected, making transport and storage straightforward. The straightforward geometry of the bits supports accurate centering and consistent hole quality across common materials.

Suitable for

• Drilling metal sheets, structural steel and non-ferrous metals
• Woodworking tasks including furniture assembly and carpentry repairs
• Plastic and composite material drilling for fittings and installations
• Workshop maintenance, service technicians and home DIY projects
• Prototype work and small-scale production where a range of sizes is needed

Key specifications

• Material: high-speed steel (HSS)
• Quantity: 25 pieces
• Diameter range: 1 mm to 13 mm
• Shank type: straight round shank suitable for standard chucks
• Packaging: compact organized case for storage and transport

How to use

Select the drill diameter appropriate for the required hole size and clamp the bit securely in the drill chuck. Use steady feed and appropriate rotational speed for the material being drilled: lower speeds for harder metals and higher speeds for wood and most plastics. Apply cutting fluid or lubricant when drilling steels to reduce heat and extend bit life. After drilling, withdraw the bit carefully while the drill is running briefly to clear chips, then stop the tool before removing the workpiece.

Recommendations

Wear appropriate eye and hand protection when drilling. For extended life of HSS drills, pre-drill with a smaller pilot bit when making large holes, keep feed pressure steady, and cool or lubricate when working with metals. Inspect bits for wear or damage and replace if cutting performance declines.
