Drill bit Proline 71445 — diameter 14 mm, length 450 mm, 1 pc

Single metal drill bit Proline 71445 with 14 mm diameter and 450 mm overall length. Designed for drilling metal and other hard materials where long reach is required, this drill bit is suitable for use in handheld drills and drill presses. The solid construction supports tasks in maintenance, fabrication and installation that require deep or through holes, providing a practical solution when extended reach and reliable cutting performance are necessary.

Advantages

The 14 mm diameter and 450 mm length combine to deliver extended reach for deep-hole drilling while maintaining sufficient stiffness for stability. The bit’s solid construction ensures compatibility with common hand-held drills and drill presses. Its geometry supports clean chip evacuation and consistent cutting in metal and other hard materials, reducing the need for repeated passes when creating deep holes.

Suitable for

• Drilling deep or through holes in metal components
• Maintenance and repair tasks requiring long-reach drilling
• Fabrication and installation work where access is limited
• Use with handheld drills and drill presses

Key specifications

• Diameter: 14 mm
• Overall length: 450 mm
• Quantity: 1 piece
• Intended materials: metal and other hard materials
• Compatible tool types: handheld drills and drill presses

How to use

Secure the drill bit in the chuck of a suitable handheld drill or drill press, ensuring the bit is tightened and aligned. Mark the drilling position and, where appropriate, center-punch to prevent wandering. Start at low speed to establish the hole, then increase speed as required for the material and tool. Apply steady pressure, withdraw periodically to clear chips when drilling deep holes, and use cutting fluid for metal to reduce heat and extend tool life.

Usage recommendations

Use appropriate personal protective equipment, clamp or secure the workpiece firmly, and select proper drill speed and cutting fluid for the material. Inspect the bit for wear before use and replace if damaged to maintain drilling accuracy and safety.
