## Long description

Proline 77517 is a long HSS metal drill bit with a 17 mm cutting diameter and an overall length of 235 mm supplied as a single piece. Designed for use in hand drills and drill presses, this fully ground drill provides accurate, straight holes in steel, non-ferrous metals and plastics. The drill features a 135° point angle with chamfering adjustment and is intended for general metal fabrication, repair and installation tasks where a long reach and precise hole geometry are required.
Advantages
The high-quality refined HSS construction offers durability and heat resistance during metalworking operations. Fully ground flutes ensure high dimensional accuracy and rectilinearity of holes, which is beneficial when working with drill bushes or performing precision drilling. The 135° point angle with chamfering adjustment helps reduce walking at startup and improves centering, while the long overall length provides extended reach for deeper or hard-to-access drilling tasks.
Suitable for
General metal fabrication and assembly work
Repair and maintenance tasks on steel and non-ferrous metals
Drilling operations in drill presses and hand-held drills
Applications requiring extended reach or drilling through thicker components

How to use
Secure the Proline 77517 drill bit in the drill chuck with correct centering and sufficient clamping force. Use appropriate cutting speeds and feed rates for HSS in the selected work material, apply cutting fluid for improved tool life and chip evacuation when drilling metals, and ensure stable workpiece clamping to maintain hole accuracy. For best results when starting the hole, use the 135° point angle to center the drill or employ a pilot or center punch if necessary.
Usage recommendations
Use appropriate drill speeds and cutting lubricant when working with steel to reduce heat and prolong tool life. When accuracy is critical, guide drilling with drill bushes or a pilot drill and avoid excessive side loads that can deflect the long shank.
