Twist Drill Bit Set - 6 Pieces - 3-8mm - Titanium Coated

These bits are designed for wood, plywood, MDF, plastic materials, and soft metals like aluminum. They are not intended for use on hardened steel, concrete, or masonry.

The 135° split point allows for precise starting without 'walking' or needing a center punch, and it helps to self-center the bit for more accurate holes.

The titanium coating increases the surface hardness of the drill bit, which improves heat resistance, reduces friction, and extends the overall lifespan of the bit.

Serrated flutes have a ridged pattern that helps to break up chips and move them out of the drilled hole more efficiently, preventing clogging and ensuring a cleaner cut.

While they can be used in drills with an impact function, they are primarily designed for standard rotary drilling. The round shank is best suited for conventional drill chucks and may not provide optimal grip in impact driver specific chucks.

Keep the bits clean and dry after use. A light coat of oil can prevent rust. Store them in a protective case or organizer to keep the tips sharp and prevent damage.

HSS is a type of tool steel known for its hardness, strength, and ability to retain its hardness even at elevated temperatures generated during drilling, making it ideal for durable drill bits.

Ensure the bit is fully inserted into the chuck and that the chuck is tightened securely. Check if the bit itself is damaged or bent.

Verify you are using the correct speed for the material. Ensure the flutes are not clogged with debris. Apply consistent, moderate pressure.

Reduce drilling speed and apply less pressure. Withdraw the bit periodically to cool down. Consider using a lubricant or cutting fluid for metal applications.

Ensure you are using a sharp bit and appropriate speed. For aluminum, a cutting fluid can help. Re-sharpening may be necessary if the tip is dull.
