Drill bit Proline 14 mm, model 91416, length 160 mm, metal drill

Proline 91416 metal drill bit with 14 mm diameter and 160 mm overall length is a single-piece high-speed steel tool intended for drilling metal and similar materials. The bit is supplied as one unit and fits standard chucks for handheld and bench drills. Its 160 mm length allows drilling deeper or through holes in workshop and construction tasks, while the 14 mm cutting diameter is suitable for common fastening and assembly needs.

Advantages

The Proline 14 mm drill bit is manufactured from high-speed steel for wear resistance during metalworking. A specially shaped solid carbide insert increases durability and cutting performance, enabling accurate, centered drilling with reduced axial load. The design incorporates a double-twist flute geometry to speed chip evacuation and allow quicker bore clearing, improving efficiency when drilling deeper holes.

Suitable for

• Drilling through and deep holes in metal sheets, plates and profiles
• Workshop and light industrial fabrication tasks
• On-site assembly, maintenance and repair work with handheld or bench drills

Key specifications

• Material: high-speed steel body with solid carbide cutting insert
• Cutting diameter: 14 mm
• Overall length: 160 mm
• Flute type: double-twist for improved chip evacuation
• Shank type: straight, compatible with standard drill chucks

How to use

Secure the drill bit in a suitable chuck and clamp the workpiece or use appropriate supports. Select a rotation speed and cutting fluid appropriate for the metal being drilled to extend tool life and improve cutting performance. Apply steady pressure without forcing the bit and withdraw periodically to clear chips when drilling deep holes. Use standard safety equipment including eye protection and gloves.

Usage recommendations

For best results on metal, use moderate spindle speeds and suitable cutting lubricant. Match drill speed and feed to the specific metal grade and thickness and check the cutting insert for wear; replace the bit if cutting quality degrades.
