Bosch Metal Drill Bit - 5.5mm

This bit is suitable for drilling alloyed and non-alloyed steel, non-ferrous metals, cast steel, cast iron, and plastics. It can also be used for pilot holes in wood.

The PointTeQ tip is self-centring, meaning it starts drilling at the exact spot you aim for without slipping or wandering. This leads to more accurate hole placement and easier starts.

The black-oxide coating on the flute helps to evacuate chips quickly and efficiently during the drilling process. This reduces clogging and maintains a faster drilling rate.

This bit has a cylindrical shank and is designed to be used with standard three-jaw drill chucks found on most corded and cordless drills.

The increased drilling rate enabled by the bit's design generates less friction and heat. The sharp, durable PointTeQ tip also maintains its cutting edge longer, contributing to reduced wear.

A faster drilling rate means you can complete holes more quickly, saving time on your projects. It also reduces the heat generated during drilling, which prolongs the life of the drill bit and the material being worked on.

Ensure the PointTeQ tip is centered on your mark. Use a centre punch to create a small indentation for the tip to seat into before drilling. Verify the drill chuck is tightened securely.

Check if the material being drilled is within the recommended compatibility list. Ensure the drill speed is appropriate for metal. Clean the flutes of any packed chips. Consider using a cutting fluid for lubrication.

Confirm the shank is clean and free of debris. Ensure the drill chuck jaws are aligned correctly and tightened evenly around the shank.

Avoid excessive force. Ensure correct drilling speed and adequate lubrication (cutting fluid) when drilling harder metals. Check if the material being drilled is appropriate for this type of bit.
