Suitable for

• Drilling in iron and cast iron
• Working with alloyed and non-alloyed steel
• Processing non-ferrous metals
• Drilling into hard plastics

When it may not be suitable

These drill bits are not intended for use on masonry, concrete, or stone, as the high-speed steel material is not designed for the abrasive nature of these surfaces. Additionally, they are not suitable for drilling into tempered or hardened steel, which may cause premature wear or damage to the cutting edges.

Key specifications

• Diameter: 3.5 mm
• Total length: 70 mm
• Material: High-speed steel
• Quantity: 2 pieces
• Application: Metal and plastic

How to use

To achieve the best results, ensure the drill bit is securely fastened in the chuck of your power drill. Mark the desired drilling point clearly before starting. Begin drilling at a low speed to establish the hole, then gradually increase the speed as needed. Maintain steady, even pressure throughout the process to prevent the bit from wandering or overheating.

What to consider before purchase

• Verify the chuck size of your drill is compatible with the bit diameter
• Ensure the material you are drilling is within the specified compatibility range
• Consider purchasing cutting oil or coolant to extend the life of the bits

Usage recommendations

For optimal performance and to prevent overheating, it is highly recommended to use a suitable coolant or cutting oil when drilling into metals. This practice helps maintain the sharpness of the cutting edges and ensures a cleaner finish.
