How to use
Secure the Proline 70830 bit in the drill chuck, ensuring it is centered and tightened. Select an appropriate rotational speed and feed rate for the metal being drilled; use lower speeds and steady feed for hard steels. Apply cutting fluid or lubricant to reduce heat and prolong bit life during deep drilling. For through-holes, withdraw the bit periodically to clear chips if necessary and maintain cooling. After use, clean chips from the flute and store the bit in a dry place to prevent corrosion.
Usage recommendations
Use appropriate personal protective equipment, clamp the workpiece firmly, and select compatible drill speed and coolant. Avoid excessive side loads to prevent breakage of the long shank.
