## Long description

Proline 91440 is a single HSS metal drill bit with a 14 mm diameter and a 400 mm overall length. The straight shank and high-speed steel construction make it suitable for drilling metal and other hard materials where a long reach is required. It fits handheld drills and drill presses and is intended for workshop or on-site use when a standard HSS bit is needed for deep holes.
Advantages
The HSS material offers wear resistance and heat tolerance for metal drilling tasks, while the 400 mm overall length provides extended reach for deep or hard-to-access holes. The straight-shank design ensures compatibility with common chucks and drill presses. The product is provided as a single piece, allowing users to replace or carry the exact diameter required without excess tooling.

Material: High-speed steel (HSS)
Diameter: 14 mm
Overall length: 400 mm
Shank type: Straight shank
Quantity: 1 piece
How to use
Select an appropriate drill speed and apply cutting fluid when drilling metal to reduce heat buildup and prolong bit life. Secure the workpiece and clamp the drill or use a drill press for better accuracy when making deep holes. Align the straight shank in the chuck and tighten securely before starting. Use steady, moderate feed pressure and periodically withdraw the bit to clear chips when drilling deep holes.
Usage recommendations
For best results, match drilling speed and lubricant to the specific metal being worked, and inspect the bit for wear before use; replace the bit when signs of bluntness or chipping appear to maintain accurate, centered holes.
