Drill bit set Proline 10864, 2 pcs, length 30 mm, for M6 threads

Proline 10864 is a compact 2-piece drill bit set with 30 mm length for creating pilot holes and preparing threads for M6 fasteners. Designed for use with handheld drills and drill presses, the bits produce consistent hole diameters suitable for subsequent tapping or for inserting screws and bolts. The set is intended for general workshop, repair and assembly tasks where reliable pilot holes are required in a variety of materials when using the appropriate drill speed and cutting method.

Advantages

The two identical drill bits offer uniform results and allow quick replacement during repetitive work. At 30 mm overall length they fit most standard chucks and allow controlled drilling depth in confined spaces. The set’s compact size makes it easy to store in a toolbox and carry between job sites. Using purpose-sized bits for M6 threads reduces the risk of oversize holes and improves thread engagement when tapping or fastening.

Suitable for

• Drilling pilot holes for M6 threaded inserts and bolts
• Preparing holes for tapping M6 threads in metal, plastic or wood
• General repair and assembly work in workshops and construction sites
• Compact toolkits for technicians and maintenance personnel

Key specifications

• Quantity: 2 drill bits
• Overall length: 30 mm
• Intended thread size: M6 (pilot drill size suited for M6 threads)
• Compatibility: suitable for handheld drills and drill presses with standard chucks
• Usable materials: metal, plastic, wood (performance depends on material hardness and drill technique)

How to use

Select the appropriate drill speed and clamping method for the material being drilled. Secure the workpiece, fit the drill bit in the chuck and set the required drilling depth. Apply steady pressure and allow the bit to cut without excessive force; withdraw periodically to clear chips when drilling metal. After drilling the pilot hole, proceed with tapping or inserting the M6 fastener as required, using lubrication where recommended for harder metals.

Usage recommendations

For best results, use cutting fluid when drilling steel, adjust drill speed for the material (higher speeds for wood and plastics, lower speeds for hard metals), and replace worn bits to maintain hole accuracy. Store the bits dry and protected to prevent corrosion and keep the set in a labeled compartment of your toolkit for quick access.
