Drill bit set Proline 10669 — 2 pieces, metal drilling

Proline 10669 is a compact two-piece drill bit set intended for general-purpose metal drilling. The set contains two steel drill bits designed to be used with compatible powered drills and hand drills for creating clean holes in a variety of metal components during repair, assembly and light construction tasks. The bits are sized and shaped for standard drilling operations and packaged for convenient storage and transport.

Advantages

The two-piece set offers a simple selection of commonly used drilling sizes for metalworking, reducing the need to change bits frequently. The bits are heat-treated and ground to maintain edge sharpness under normal use, and their compact packaging makes them easy to carry in a toolbox or workshop drawer. These metal drill bits are suitable for repetitive drilling in thin to medium-thickness metal sheets and components.

Suitable for

• Drilling holes in sheet metal and thin metal plates
• Repair and maintenance tasks involving metal components
• Assembly work where metal fastener holes are required
• Light fabrication and DIY metalworking projects

Key specifications

• Set size: 2 drill bits
• Intended material: metal
• Material: hardened steel (heat-treated)
• Compatibility: designed for use with standard handheld and powered drills
• Packaging: compact storage case for easy transport

How to use

Select the appropriate drill bit from the set for the hole diameter you need and secure it firmly in the drill chuck. Mark the drilling location on the metal surface, clamp the workpiece if possible to prevent movement, and use a center punch to create a starting dimple if drilling thin or slippery materials. Begin drilling at low speed to establish the hole, then increase speed as needed while applying steady moderate pressure. Use cutting fluid or lubricant when drilling harder metals to reduce friction and heat buildup, and clear metal shavings regularly to maintain cutting efficiency.

Usage recommendations

Wear appropriate eye and hand protection when drilling. For best life and performance, avoid excessive side load on the bits and maintain moderate drilling speeds with suitable lubrication for the metal being drilled.
