Drill bit Proline 71035, metal, Ø 10 mm, length 350 mm, 1 pc

Proline 71035 is a single metal drill bit with a 10 mm diameter and a total length of 350 mm, designed primarily for drilling metal. The solid shank and cutting geometry make this drill bit suitable for deep drilling and through-hole work in steel and other ferrous materials. It is compatible with standard hand drills and drill presses used in construction, maintenance and industrial environments.

Advantages

The drill bit features a robust construction that supports stable drilling performance and reduced deflection during long holes. Its cutting geometry and double twist design assist chip evacuation and bore stability, enabling efficient penetration in metal. The 350 mm length provides extended reach for tasks that require access through thick sections or confined assemblies.

Suitable for

• Through-holes in steel plates and structural sections
• Deep drilling where extended length is required
• General maintenance and repair work on metal components
• Use with hand drills and drill presses in workshops and construction sites

Key specifications

• Material application: metal (ferrous materials)
• Diameter: 10 mm
• Total length: 350 mm
• Shank type: solid shank
• Cutting geometry: multi-flute / optimized for chip evacuation
• Pack quantity: 1 piece

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring firm clamping on the solid shank. Mark and centre the drilling point, apply steady feed pressure and run the drill at an appropriate speed for metalworking. Use cutting lubricant or coolant when drilling steel to reduce heat build-up and extend tool life. Withdraw the bit periodically to clear chips when making deep holes.

Usage recommendations

For best results when drilling ferrous metals, use moderate speeds, apply cutting fluid, and ensure the workpiece is firmly clamped. Inspect the drill bit for wear or damage before use and replace it when cutting performance degrades.
