Proper hole preparation for wood screws normally requires three separate operations: pilot hole drilling, clearance hole drilling and countersink drilling. Then the screw can be installed – a fourth operation. This is so time-consuming that most woodworkers skip over the steps, trying to save time and labor. While that works sometimes, it causes poor joints or splitting wood other times.
Sawinery’s Countersink Drill Bit Set streamlines this process into one easy step, combining a tapered drill bit with an attached countersink. This set, designed to match the three most common wood screw sizes, makes quick work of wood joints without compromising strength or risking wood splitting.
Highlights:
Comprehensive Set: Includes countersink drill bits for #6, #8, and #10 screws, covering the most commonly used wood screw sizes.
Tapered Drill Bit Design: Ensures a wide clearance for the non-threaded part of the screw while creating a pilot hole for the threaded section, reducing wood stress.
Depth Control: The adjustable stop collar allows precise countersink depth, ensuring screw heads sit flush with or below the wood surface.
Counterbore Option: By removing the stop collar, the countersink functions as a counterbore, creating space for wood plugs to conceal screws.
¼-Inch Hex Shank: Provides a secure grip with drill chucks and is compatible with impact drivers, ensuring reliable performance across tools.
