## Long description

Proline 77170 is a single metal drill bit with a 17 mm diameter and overall length of 184 mm designed for drilling holes in steel, iron and other ferrous materials. The straight shank fits both hand drills and drill presses. Manufactured from refined high-speed steel and produced entirely by grinding, this drill bit is built for precision, straightness of holes and improved durability in metalworking and repair applications.
Advantages
The drill bit features a 135° point angle with chamfering adjustment that facilitates rapid drilling and reduces the need for extensive centre punching. Full grinding manufacture ensures high concentricity and straightness of the hole, while refined HSS material provides increased abrasion resistance, resilience and torsional strength for demanding metalworking tasks. Supplied individually in a protective plastic tube for secure storage and transport.
Suitable for
 Drilling holes in steel and iron components
 Maintenance and repair in workshops and industrial settings
 Metal fabrication and assembly tasks requiring precise, straight holes
 Use with hand drills and drill presses
Key specifications
 Diameter: 17 mm
 Overall length: 184 mm
 Point angle: 135° with chamfer adjustment
 Material: refined high-speed steel (HSS)
 Manufacture: fully ground flutes for high precision and straightness
 Enhanced abrasion resistance, resilience and torsional strength
 Shank type: straight shank, suitable for standard chucks
 Packed singly in a protective plastic tube
How to use
Secure the drill bit firmly in the drill chuck, ensuring the straight shank is fully seated. Mark and, if needed, centre-punch the drilling location to improve accuracy. Use an appropriate spindle speed and feed for metal drilling—moderate speed for larger diameters—and apply steady pressure without forcing the bit. Use cutting fluid or coolant for prolonged drilling sessions to reduce heat and extend tool life. Clear chips regularly to maintain cutting efficiency.
Usage recommendations
For best results when drilling steel and other ferrous materials, start with a light pilot hole if extreme positional accuracy is required, use cutting fluid to reduce friction and heat, and allow the bit to clear chips frequently. Inspect the bit for wear before use and replace when signs of deformation or excessive dulling appear to maintain hole quality and operator safety.
