Bosch HSS PointTeQ Drill Bit - 2.2mm

This drill bit is suitable for drilling alloyed and non-alloyed steel, non-ferrous metals, cast steel, cast iron, and plastics.

The self-centering design of the PointTeQ tip engages the material immediately upon contact, guiding the bit accurately and preventing it from skidding across the surface.

No, this HSS twist drill bit is specifically designed for metals and plastics. For concrete or masonry, you would need a masonry drill bit.

The black-oxide coating on the flute helps to create a harder surface, improve chip evacuation, and resist corrosion, contributing to the bit's durability and performance.

A 135-degree tip angle is standard for drilling metal. It provides a good balance of penetration speed and tool life, and is effective for self-centering on harder materials.

While the bit has a standard cylindrical shank compatible with chucks, it is not designed for hammer drilling. Using it in hammer mode could damage the bit or your drill.

Wipe the drill bits with a clean cloth to remove metal shavings and dust. A mild solvent can be used for stubborn residue. Ensure they are completely dry before storing.

Ensure the PointTeQ tip is properly seated against the material surface before starting the drill. A small dimple can be created with a center punch to guide the initial contact.

Reduce drilling speed, apply moderate pressure, and use a cutting lubricant or coolant. Ensure chips are being cleared effectively.

Reduce drilling pressure, ensure the bit is perpendicular to the material, and check for any binding in the hole. For smaller bits like this 2.2mm, be particularly mindful of excessive force.

Clear chips more frequently by retracting the drill bit from the hole. Ensure the flute is not clogged. Consider a slightly slower drilling speed.
