How to use

Secure the workpiece and select a suitable drill speed for the material. Install the 5 mm KWB drill bit in the chuck of your drill and ensure it is tightly clamped. Begin drilling with steady pressure, maintaining alignment with the intended hole. Periodically withdraw the bit to clear chips and prevent overheating; the wave profile aids in chip removal. After drilling, deburr the hole if necessary.

Recommendations

Use cutting fluid or lubricant when drilling into harder metals to extend tool life. Wear appropriate personal protective equipment such as safety glasses and gloves, and ensure the drill is operated at recommended speeds for the material being worked.
