Drill bit set Proline 10841 — 2 pcs, length 75 mm, for M6 threads

Proline 10841 is a set of two drill bits, each 75 mm long, designed to create precise pilot holes for M6 threaded fasteners. Intended for preparatory drilling before tapping or for making clearance and pilot holes for M6 bolts and screws, these bits suit common metalworking and assembly workflows. The compact two-piece set is convenient for workshop toolkits and field service kits where paired bits for M6 thread operations are needed.

Advantages

The Proline 10841 drill bit set offers consistent hole diameter and straightness appropriate for M6 threading preparations. With a 75 mm length, the bits provide sufficient reach for standard sheet and plate thicknesses as well as many assembly scenarios. The two-piece format ensures a spare bit is available, reducing downtime during repetitive tasks. The bits are compatible with standard drill chucks and handheld drilling tools, enabling straightforward integration into existing toolsets.

Suitable for

• Preparing pilot holes before tapping M6 threads
• Drilling clearance or starting holes for M6 bolts and screws
• Metalworking and light fabrication tasks
• Maintenance and assembly in workshops and service vehicles

Key specifications

• Quantity: 2 pieces
• Length: 75 mm per drill bit
• Intended thread size: for use with M6 threaded fasteners (pilot/drill size)
• Compatibility: suitable for standard drill chucks and handheld drills
• Application: preparatory drilling for threading, clearance and pilot holes in metals and common construction materials

How to use

Select an appropriate drill speed and secure the workpiece before drilling. Mark the intended hole position, clamp the piece to prevent movement and use a center punch if needed to guide the bit. Install a 75 mm Proline 10841 drill bit in a standard drill chuck, align perpendicular to the work surface and drill steadily with moderate pressure. For threading, drill to the recommended depth and then proceed with tapping operations for M6 threads. Replace the second bit as a spare or for continued drilling if wear occurs.

Usage recommendations

Use cutting fluid or lubricant when drilling tougher metals to extend bit life and improve hole quality. Start at low speed for accurate positioning and increase speed as required by the material. Inspect drill bits for wear and replace when dull to maintain consistent hole diameter for reliable M6 threading.
