Drill Bit Makita D-07369 12 mm x 250 mm - masonry/wood/metal use

Makita D-07369 is a 12 mm diameter, 250 mm long drill bit designed for extended-reach general drilling tasks. It is intended for use with compatible drills where a standard-length bit does not provide sufficient depth. The bit is suitable for drilling into masonry, wood and metal when used with the appropriate drill mode and speed, offering the ability to make deeper holes for repair, installation or construction jobs.

Advantages

The extended 250 mm length provides reach into recessed or deep mounting points without the need for extensions. A 12 mm cutting diameter balances material removal and stability for a wide range of applications. The bit is produced to fit common drill chucks and to withstand the axial loads associated with deeper drilling, helping to maintain straight holes and consistent cutting performance across masonry, wood and metal when the correct drill settings and accessories are used.

Suitable for

• Drilling deeper anchor or mounting holes in masonry walls
• Reaching through timber beams or thick wooden panels
• Creating long-through holes in sheet metal or structural metal parts
• Repair and renovation tasks requiring extended-reach drilling

Key specifications

• Shank diameter: compatible with common drill chucks (suitable for 12 mm cutting diameter)
• Cutting diameter: 12 mm
• Overall length: 250 mm
• Intended materials: masonry, wood, metal (use appropriate drill speed and mode)
• Design: straight long-reach drill geometry for stable drilling

How to use

Select a drill with a chuck that securely accepts the bit shank and set the drill mode appropriate for the target material (rotary with hammer for masonry, rotary only for wood and metal unless using an impact driver specified for metal). Mark the drilling position and, where necessary, start with a pilot mark to prevent walking. Use controlled feed pressure, maintain drill alignment, and clear debris from the hole frequently when drilling to full depth. For metal, use suitable cutting fluid; for masonry, use intermittent pulling out to remove dust and avoid overheating the bit.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves. Match drill speed, feed pressure and drill mode to the material, and ensure the bit is clamped securely in the chuck. Replace the bit when wear affects cutting performance or hole quality.
