Drill bit set Proline 10842, 2 pcs, length 75 mm, for M7 thread

Proline 10842 is a set of two drill bits with a length of 75 mm designed to create holes compatible with M7 thread size. The pair is intended for use with hand drills and drill presses and is suitable for metalworking and mechanical assembly where precise hole diameter is required for subsequent M7 threading or fastening. The bits are supplied as a small two-piece pack for quick replacement or dual-station use.

Advantages

The drill bit set offers consistent diameter and straightness over the 75 mm length, enabling accurate pilot or through holes that match M7 thread requirements. The two-piece pack provides convenience for repeat jobs or for maintaining workflow while one bit is being reconditioned. The bits are compatible with common chuck sizes on hand drills and bench drills, making them suitable for a variety of workshop setups.

Suitable for

• Creating holes prior to cutting M7 threads
• General metal drilling in mechanical assembly
• Use with hand drills and drill presses
• Workshop maintenance and light fabrication tasks

Key specifications

• Quantity: 2 pieces
• Length: 75 mm
• Target thread compatibility: M7
• Intended material use: metals and similar rigid materials
• Suitable for: hand drills and drill presses

How to use

Select the appropriate drill speed and secure the workpiece before drilling. Clamp the bit in the drill chuck and align the tip with the marked centre on the workpiece. Use steady feed pressure and coolant or cutting fluid where recommended for metal drilling to prolong bit life and improve hole quality. After drilling the pilot hole, inspect the diameter and remove any burrs before tapping M7 threads.

Usage recommendations

For best results when preparing holes for M7 threads, use cutting fluid, moderate drill speeds appropriate to the material, and ensure the workpiece is firmly clamped. Replace or resharpen bits that show wear to maintain accurate hole diameter and reduce the risk of tap breakage.
