Drill bit Proline 91460, metal, Ø14 mm, length 600 mm, 1 pc

Proline 91460 is a single metal drill bit with a 14 mm diameter and a total length of 600 mm, supplied as one piece. Designed for metalworking, this solid bit is intended for deep or through drilling in steel and other metals. Its extended length makes it suitable for drill presses and heavy-duty hand drills when longer reach or longer holes are required.

Advantages

The solid design provides stability during extended drilling operations and helps maintain concentricity. A specially shaped cutting geometry increases durability and contributes to accurate centered drilling. The double-twist flute design accelerates chip evacuation, reducing load on the tool and enabling more efficient drilling in metal materials.

Suitable for

• Deep-hole drilling in steel and other metals
• Through-holes where extended reach is required
• Use in drill presses and heavy-duty hand drills
• Industrial and professional metalworking applications

Key specifications

• Material application: metal
• Diameter: 14 mm
• Total length: 600 mm
• Quantity: 1 piece
• Solid construction for improved stability
• Double-twist flute geometry for faster chip removal

How to use

Select an appropriate drill speed and feed rate for the metal being worked, secure the workpiece, and clamp the long drill bit rigidly in the drill chuck or spindle to minimize runout. Use cutting fluid suitable for the metal to reduce heat and wear. Begin drilling with light pressure until the bit is centered, then apply steady feed. Retract periodically if drilling deep to clear chips and refresh cutting fluid.

Usage recommendations

For best results in industrial or professional settings, use a compatible coolant or cutting oil, maintain correct spindle alignment, and avoid excessive side load. Inspect the bit before each use and replace it when wear affects cutting performance or concentricity.
