## Long description

Proline 77730 is a single HSS metal drill bit with a 13 mm diameter and a total length of 375 mm. Intended for drilling steel, non-ferrous metals and plastics, this straight extra-long drill bit is fully ground to deliver accurate, rectilinear holes and is suitable for deeper or through-hole drilling in workshop and construction settings. The bit is supplied as one piece and fits standard chucks that accept a 13 mm shank.
Advantages
The 135° point angle with chamfering adjustment allows quick penetration and reduces the need for frequent repositioning during marking out. Full grinding of the flute and body ensures high dimensional accuracy and straightness of holes, which is especially useful when drilling with drill bushes. Made from refined high-speed steel (HSS), the bit provides consistent hardness and wear resistance for general metalworking tasks. Its extra length enables access to recessed areas and the creation of deep through-holes without extensions.
Suitable for
 Drilling deep or through-holes in steel
 Drilling non-ferrous metals (aluminum, brass, copper)
 Drilling plastic components
 Workshop, maintenance and construction tasks requiring long-reach drilling
 Use with drill bushes and jigs where hole straightness is critical
Key specifications

 Diameter: 13 mm
 Total length: 375 mm
 Type: straight extra-long ground drill bit
 Pack quantity: 1 piece
How to use
Secure the drill bit in a compatible drill chuck rated for a 13 mm diameter. Mark and, if required, center-punch the workpiece to prevent wandering. Use appropriate cutting speeds and feed rates for the material being drilled; reduce speed for harder steels and increase speed for softer non-ferrous metals and plastics. Apply steady pressure and allow the bit to cut without excessive force to maintain straightness. Use cutting fluid when drilling steel to reduce heat and prolong tool life. Clear chips regularly, especially when drilling deep holes.
Usage recommendations
For best results when drilling deep or through-holes, clamp the workpiece securely, use drill bushes or guides to maintain alignment, and employ suitable cutting lubricant for metalworking. Inspect the bit for wear and regrind or replace when accuracy degrades.
