Drill bit Proline 71860, metal, ø18 mm, length 600 mm, 1 pc

Proline 71860 is a single metal drill bit with an 18 mm diameter and 600 mm overall length, intended for drilling metalwork and other construction materials where extended reach is required. The bit features a straight shank and a solid one-piece design compatible with hand-held drills and drill presses. It is intended to cut through steel and similar materials; its length and diameter are suitable for applications that demand a long-reach Ø18 mm hole.

Advantages

The Proline 71860 drill bit combines a long 600 mm length with an 18 mm cutting diameter to enable deep or hard-to-reach holes in metal and related materials. Its straight shank provides stable clamping in standard chucks, while the single-piece metal construction ensures durability under typical drilling loads. The design supports both hand-held and bench drilling equipment, allowing flexible use across sites and workshops.

Suitable for

• Drilling deep or long-reach Ø18 mm holes in steel and metalwork
• Use with hand-held drills and drill presses
• Industrial and professional metalworking tasks requiring extended reach
• Construction site applications where a long drill length is necessary

Key specifications

• Material application: metal and similar construction materials
• Cutting diameter: 18 mm
• Overall length: 600 mm
• Shank type: straight shank for standard drill chucks
• Quantity in pack: 1 piece

How to use

Secure the drill bit in a compatible chuck ensuring sufficient clamping depth on the straight shank. Select an appropriate rotational speed and feed rate for metal drilling, and use cutting lubricant where recommended for steel to improve cutting performance and tool life. Begin drilling at a steady pressure, keeping the drill perpendicular to the workpiece to maintain hole accuracy. Clear chips periodically when drilling deep holes to prevent overheating and ensure consistent cutting.

Usage recommendations

For best results when drilling steel or similar materials, use a drill press where possible to maintain alignment and reduce runout. Apply suitable cutting fluid and moderate speed to extend bit life. Inspect the bit for wear before use and replace when cutting becomes inefficient or the edge is damaged.
