Drill Pilot Bit MODECO MN-76-122 8 mm diameter, 135 mm length

MODECO MN-76-122 pilot drill bit with an 8 mm cutting diameter and 135 mm overall length is designed to create precise starter holes for larger drills, screws or dowels. The bit is intended for use in wood, wood-based composites and other similar soft materials where a straight, stable guide hole is required. Its length provides sufficient reach for deeper starter holes while maintaining control when used with handheld drills and drill presses.

Advantages

The pilot bit delivers accurate centering to reduce wandering when starting holes and to improve the fit of subsequent fasteners or larger drill bits. Its 8 mm diameter and extended length ensure consistent depth and alignment in through or blind holes. Compatibility with standard drill chucks makes it convenient for both portable and bench drilling operations. The design supports clean chip evacuation in soft materials, helping preserve the hole walls and reduce splitting.

Suitable for

• Drilling starter holes for screws and dowels in solid wood and laminated boards
• Creating pilot holes prior to using larger diameter drill bits
• Use in handheld electric drills and drill presses for furniture assembly and joinery
• Tasks requiring controlled depth and straight alignment in soft materials

Key specifications

• Cutting diameter: 8 mm
• Overall length: 135 mm
• Material suitability: wood, wood-based composites and similar soft materials
• Compatibility: standard drill chucks on handheld drills and drill presses
• Function: pilot/drill starter bit for guiding larger drills and fasteners

How to use

Secure the drill bit in the drill chuck and tighten firmly. Mark the intended hole position on the workpiece, then place the tip of the pilot bit at the mark with the drill held perpendicular to the surface. Start drilling at low speed to establish the initial cut, then increase speed as needed while applying steady pressure. For deeper holes, periodically withdraw the bit to clear chips and prevent clogging. When adequate depth is reached, stop the drill and remove the bit.

Usage recommendations

Use appropriate clamping to secure the workpiece and wear eye protection. Select a drilling speed suitable for wood to avoid burning or tear-out; moderate speeds generally produce cleaner holes. If working near edges or with thin material, consider backing the workpiece to reduce splintering. Clean and store the bit dry to maintain cutting performance.
