Drill bit Proline 70811 — metal drill bit Ø8 mm, length 110 mm, 1 pc

Proline 70811 — metal drill bit Ø8 mm, length 110 mm, 1 pc is a single straight-shank drill bit designed for cutting metal. With an 8 mm working diameter and a total length of 110 mm, this Proline bit fits drills and drivers that accept standard straight shanks. It is intended for creating through-holes, pilot holes and general metalworking tasks that require an 8 mm bore.

Advantages

The Proline 70811 drill bit provides a consistent 8 mm diameter hole with a 110 mm overall length that gives extra reach compared with shorter bits. Its straight shank ensures secure clamping in standard chucks, and the single-piece construction supports stable drilling performance in metal. The bit is sold as a single unit for targeted replacement or specific tasks where only one 8 mm drill is required.

Suitable for

• Drilling through metal sheets and plates
• Making pilot holes for bolts and fasteners
• General metal fabrication and maintenance work
• Use with hand drills and drill drivers that accept straight shanks

Key specifications

• Material target: metal
• Diameter: 8 mm
• Overall length: 110 mm
• Shank type: straight shank
• Quantity: 1 piece

How to use

Clamp the drill bit securely in the drill chuck so the straight shank is fully seated. Select an appropriate drilling speed for the metal type and use cutting fluid or lubricant for cleaner holes and reduced bit wear. Apply steady, moderate pressure while keeping the drill perpendicular to the workpiece; withdraw the bit occasionally to clear chips when drilling deeper holes to maintain cutting efficiency and prevent clogging.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drilling speed and feed rate to the specific metal being drilled and lubricate when recommended to extend tool life and improve hole quality.
