Drill bit Proline 76145P — metal, Ø 14.5 mm, length 169 mm, 1 pc

Proline 76145P is a metal drill bit designed for producing large-diameter holes in metal and other hard materials. With a diameter of 14.5 mm and an overall length of 169 mm, this single-piece bit is made from HSS refined steel and conforms to DIN 338 compatibility, providing the rigidity and wear resistance needed for workshop and construction drilling tasks. The tool is supplied in a protective PVC case and features a 13 mm relief suitable for use with compatible electric drills and drill presses.

Advantages

The Proline 14.5 mm drill bit offers high cutting performance and durability thanks to its HSS refined steel construction. Conformity with DIN 338-compatible shank dimensions ensures reliable fit and stable operation in standard chucks. The 13 mm relief improves chip clearance and reduces friction during drilling, while the protective PVC case helps prevent damage during storage and transport.

Suitable for

• Drilling holes in steel and other ferrous materials
• Creating large-diameter openings in non-ferrous metals
• Workshop and maintenance drilling tasks with electric drills or drill presses
• Construction and fabrication tasks requiring precise, deep holes

Key specifications

• Material: HSS refined steel
• Diameter: 14.5 mm
• Overall length: 169 mm
• Relief length: 13 mm
• Compatibility: DIN 338-compatible shank profile
• Packaging: single piece in a PVC case

How to use

Secure the drill bit firmly in a compatible chuck or drill press with a DIN 338-compatible holder before starting. Mark the drilling position and, if required, use a center punch to prevent wandering. Use appropriate cutting speeds and apply steady pressure; reduce feed when penetrating through-thickness changes or hard spots. Use cutting fluid or coolant when drilling ferrous metals to extend tool life and improve chip evacuation. After use, clean chips from flutes and store the bit in its PVC case to protect the cutting edges.

Usage recommendations

For optimal results when drilling metals, select a slow to medium cutting speed, apply cutting fluid, and avoid excessive lateral forces. Inspect the bit regularly for wear; replace when the cutting edge becomes blunt or when vibration increases to maintain hole quality and operator safety.
