## Summary description

Single Proline 77145 metal drill bit with a diameter of 14.5 mm and overall length 169 mm.

Suitable for through-holes and general metalworking where the stated diameter and length meet project requirements.

## Long description

Single Proline 77145 metal drill bit with a diameter of 14.5 mm and overall length 169 mm. Manufactured from high-speed steel (HSS) and produced by grinding to ensure straightness and precise concentricity, this one-piece drill bit is designed for drilling through-holes and general metalworking tasks. The 135° point angle with chamfering adjustment improves centring and enables quick drilling starts, while increased abrasion resistance and torsional strength provide reliable performance in workshop, maintenance and fabrication applications.
Advantages
The Proline 77145 drill bit is ground entirely rather than cylindrical ground, which delivers higher precision and straighter holes. Made from refined HSS, it offers increased wear resistance and enhanced resilience under torsional loads. The 135° point angle with chamfering adjustment shortens the time needed for centre punching and reduces walking at drill start. Supplied as a single piece in a protective plastic tube, it is easy to store and transport.
Suitable for
 Drilling through-holes in steel and other metals
 Workshop and maintenance tasks requiring a 14.5 mm diameter
 Fabrication and metal assembly where a 169 mm overall length is required
 Use with compatible handheld or bench drills for general metalworking

How to use
Select a drill or drill press that accepts a 14.5 mm shank and secure the Proline 77145 bit in the chuck according to the tool manufacturer’s instructions. Mark and, if necessary, centre-punch the drilling point to reduce walking. Use appropriate cutting speeds and feed rates for HSS when drilling metal, and apply cutting fluid or coolant to extend tool life and improve chip evacuation. Maintain steady pressure and allow the bit to cut without excessive force; clear chips periodically when drilling deep holes.
Usage recommendations
Use the Proline 77145 drill bit with compatible drills and appropriate cutting fluid for best results; avoid excessive side loads and overheating to preserve edge life and dimensional accuracy.
