Drill bit Proline 70611 — metal HSS Ø6 mm, length 110 mm, 1 pc

Proline 70611 is a single high-speed steel (HSS) drill bit with a 6 mm diameter and an overall length of 110 mm. Designed primarily for metalworking, this drill bit suits drilling through steel, iron and similar materials where a standard twist geometry is appropriate. Supplied as one piece, the Proline 70611 is intended for precision through-holes and general-purpose metal drilling in hand drills and drill presses.

Advantages

The HSS material provides wear resistance and reliable cutting performance when drilling metals. Its 6 mm diameter and 110 mm length offer a balance between rigidity and reach for typical metalworking tasks. The standard twist geometry supports stable drilling and efficient chip evacuation, allowing for accurate, consistent holes when used with appropriate speeds and lubrication.

Suitable for

• Drilling through steel sheets and plates
• Creating precision through-holes in metal components
• General maintenance and repair work with hand drills or drill presses
• Workshop and light industrial metalworking tasks

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 6 mm
• Overall length: 110 mm
• Geometry: Standard twist drill
• Pack quantity: 1 piece

How to use

Secure the workpiece and mark the drilling position. Use an appropriate drill chuck rated for a 6 mm shank and set the drill or press to a speed suitable for the metal being drilled. Apply steady feed pressure while keeping the drill aligned perpendicular to the surface. For harder steels, use cutting fluid or lubricant to reduce heat and prolong tool life. Clear chips regularly and back the bit out occasionally to prevent clogging.

Usage recommendations

For best results, select drilling speeds and feed rates matched to the specific metal; use coolant or cutting oil for stainless and hardened steels. Inspect the bit for wear or chipping before use and replace when cutting performance degrades.
