Key specifications
 Overall length: 400 mm
 Shank type: hex shank for secure grip
 Pack: single piece
 Suitable for use in standard drill chucks and quick-change holders
 Designed for deep-hole, extended-reach drilling applications
How to use
Fit the hex shank securely into a compatible drill chuck or quick-change holder, ensuring the bit is clamped firmly to prevent slipping. Select an appropriate drilling speed and apply steady, even pressure; avoid lateral forces that could bend the long bit. When drilling deep holes, periodically withdraw the bit to clear chips and reduce heat buildup. Use appropriate personal protective equipment and follow the drill manufacturer's safety instructions.
Usage recommendations
For best results, match drill speed and feed to the material being drilled, clear chips frequently when working at full depth, and use a pilot hole when accuracy is critical. Store the bit protected from impacts to preserve straightness and cutting performance.
