Drill bit Proline 91835 — metal, Ø18 mm, length 350 mm, 1 pc

Proline 91835 — metal drill bit, Ø18 mm, length 350 mm, 1 pc is a single-piece drill for drilling metal with an extended working length of 350 mm. The bit is intended for use in power drills and drill presses where long reach is required for deep holes in metal components. Its 18 mm diameter and solid construction make it suitable for maintenance, fabrication and construction tasks that require accurate, centered holes at extended depths.

Advantages

The Proline 91835 drill bit features a specially shaped solid carbide insert designed to improve durability and cutting effectiveness while maintaining accurate, centered drilling. Its extended 350 mm working length provides access to deep or hard-to-reach points without the need for extensions. The combination of solid construction and optimized flute geometry supports chip evacuation to reduce load on the tool and help maintain drilling speed and stability.

Suitable for

• Drilling deep holes in metal plates and structural components
• Maintenance and repair tasks requiring extended reach
• Metal fabrication where precise, centered holes are needed
• Use with power drills and drill presses for industrial and professional applications

Key specifications

• Diameter: 18 mm
• Working length: 350 mm
• Material type: solid construction with carbide insert for cutting edge
• Intended material: metal
• Quantity: 1 piece

How to use

Secure the Proline 91835 drill bit in a compatible chuck, ensuring tight and concentric clamping. Select an appropriate rotational speed for drilling metal and apply steady feed pressure; avoid excessive force that could overload the drill or bit. For deep-hole drilling, periodically withdraw the bit to clear chips and improve coolant penetration if using cutting fluid. When using a drill press, ensure the workpiece is firmly clamped and aligned to maintain centered holes.

Usage recommendations

Use cutting fluid or coolant for most metal-drilling applications to reduce heat and extend tool life. Match drill speed and feed to the metal type and thickness; lower speeds are generally recommended for harder metals. Inspect the carbide cutting edge for wear and replace the bit when performance or hole quality declines.
