Drill bit Condor Confirmat 4.0/6.0 mm for confirmat screws

Condor Confirmat drill bit 4.0/6.0 mm is a specialist woodworking bit designed for drilling pilot and seating holes for confirmat screws. The two-step geometry provides a 4.0 mm pilot hole followed by a 6.0 mm body diameter, producing a precise profile for the screw shank and head to locate securely in particleboard, MDF and similar engineered panels. The bit is suitable for use in hand-held drills and drill presses and is intended for furniture assembly and joinery tasks where consistent alignment and screw retention are required.

Advantages

The two-diameter design integrates pilot drilling and clearance shaping in a single pass, reducing the need for separate countersinking operations and improving accuracy. Hardened cutting edges maintain consistent hole dimensions, while the stepped profile minimizes splitting and tear-out in laminated and composite panels. Compatibility with standard drill chucks allows straightforward use in workshop and on-site environments.

Suitable for

• Drilling pilot and seating holes for confirmat screws in particleboard.
• Preparing MDF panels for furniture assembly.
• Workshop and on-site furniture repair and installation.

Key specifications

• Pilot diameter: 4.0 mm
• Body/seat diameter: 6.0 mm
• Two-step/stepped geometry for combined pilot and seating hole
• Designed for use in engineered panel materials such as particleboard and MDF
• Suitable for hand drills and drill presses with standard chucks

How to use

Mark the intended screw location and secure the panel to prevent movement. Select a drill speed appropriate for the panel material—moderate speed for particleboard and MDF—and align the bit perpendicular to the surface. Drill with steady pressure until the stepped section reaches the surface to create the seating profile for the confirmat screw. Clear chips from the hole as needed and inspect the seat before inserting the screw.

Usage recommendations

For consistent results, clamp workpieces and use a drill guide or drill press when possible. Use moderate speed and avoid excessive feed force to reduce overheating and edge chipping. When installing near edges, allow adequate margin to prevent splitting and consider a scrap test piece to verify hole fit before final assembly.
