Set of 4 HSS self-centering drill bits for hinges, designed for carpenters, cabinetmakers and furniture makers.

Precision Self-Centering Drill Bit: Self-centering precision drill bits are essential for pilot holes in hinges, handles, drawer slides, and other parts. The cone surrounding the drill bit ensures the pilot hole is centered relative to the countersunk hole. Drilling a pilot hole:
Sharp: The 135-degree angled edge of the drill bit head allows for faster drilling into the hinge hole position. The guide surrounding the drill bit is spring-loaded to keep it in contact with the countersunk hole in the part being repaired.
Automatically Discharged Wood Chips: Sawdust is automatically discharged from both sides of the holes. Without the drill bit clogging, you don't need to remove wood chips, thus efficiently increasing your workload.
Easy to Use and Install: Different wood hardnesses require a centering drill bit. If it's different, you just need to remove the screw and replace the drill bit. Professional video tutorials on how to use these tools will be provided.
