Drill bit set Proline 10865, 2 pieces, length 30 mm, for M7 threads

Proline 10865 is a two-piece drill bit set with 30 mm length designed for creating accurate pilot holes and preparing material for M7 threaded fasteners. The set contains two bits matched to the requirements of M7 threads and is suitable for use in metal and wood depending on the drill and material. These compact bits fit standard chucks and are intended for assembly, repair and fastening tasks where M7 components are used.

Advantages

The Proline 10865 drill bit set offers consistent hole sizing and straight drilling thanks to its matched pair design and 30 mm working length. Its compact dimensions provide greater control in confined spaces and when working with hand-held drills. The bits are manufactured to standard dimensions for compatibility with common M7 tapping and fastening practices. Their universal shank profile permits quick fitting into most drill chucks.

Suitable for

• Drilling pilot holes for M7 taps and threaded inserts
• Preparing metal and wood for M7 fasteners in assembly work
• Repair and maintenance tasks requiring precise small-diameter holes
• Hobby and DIY projects that use M7 bolts or studs

Key specifications

• Number of pieces: 2
• Overall/working length: 30 mm
• Intended thread size compatibility: M7 (for pilot hole preparation)
• Suitable materials: metal and wood (depending on drill, speed and feed)
• Shank: standard cylindrical shank for conventional drill chucks

How to use

Select an appropriate drill speed and clamp the workpiece securely before drilling. Mark the hole position and center-punch if working on metal to prevent wandering. Fit the required Proline 10865 bit into the drill chuck and tighten securely. Advance the bit with steady, even pressure; for metal use cutting fluid and reduce speed as necessary. Clear chips frequently and back the bit out periodically to avoid clogging. After drilling the pilot hole, proceed with tapping or inserting the M7 fastener following standard practices.

Usage recommendations

For best results when drilling metal, use low-to-moderate speed and apply cutting lubricant. When working with wood, higher speeds and steady feed are acceptable but avoid excessive pressure to prevent overheating or tear-out. Inspect bits for wear before use and replace if the cutting edges are blunt to maintain precise hole dimensions.
