## Long description

Proline 77715 metal drill bit, single piece with a diameter of 11.5 mm and overall length 365 mm, intended for drilling in steel, non‑ferrous metals and plastics. Manufactured from high‑quality refined HSS, this extra‑long, fully ground straight shank bit provides accurate, rectilinear holes and is suitable for use with compatible drills and drill presses for fabrication, maintenance and repair tasks that require a mid‑size hole.
Advantages
The 135° point angle with chamfering adjustment enables rapid penetration and reduces the need for extensive marking out. Fully ground geometry ensures high drilling accuracy and straightness of holes, making the bit suitable for use with drill bushes. Extra length allows access to deeper or recessed positions while maintaining concentricity. Supplied as a single piece in its case for controlled storage and transport.
Suitable for
Drilling mid‑size holes in steel components
Working with non‑ferrous metals such as aluminum and brass
Drilling plastics and composite materials
Use with drill presses and hand drills where extra reach is required
Maintenance, repair and fabrication tasks requiring precise hole placement
Key specifications
Diameter: 11.5 mm
Total length: 365 mm
Point angle: 135° with chamfering adjustment
Shank type: straight shank
Material: refined high‑speed steel (HSS)
Flute: fully ground for accuracy and rectilinearity
Pack content: 1 piece
How to use
Secure the drill bit in a compatible drill chuck or drill press ensuring proper centring and clamping on the straight shank. Select appropriate spindle speed and cutting fluid for the work material—lower speeds and cutting lubricant for steel, higher speeds for softer non‑ferrous metals and plastics. Use steady feed pressure without forcing the bit; withdraw periodically to clear chips when drilling deep holes. When using drill bushes, the fully ground geometry will help maintain hole straightness and repeatability.
Usage recommendations
For best results when drilling steel, use cutting oil and moderate drill speeds. For aluminum and other non‑ferrous metals, a light lubricant and higher speeds are recommended. Inspect the bit for wear or damage before use and replace when cutting performance declines to maintain hole quality and operator safety.
