We’ve seen self-centering bits around for awhile, but we wonder if it’s worth buying yet another set of drill bits. Manufacturers and retailers claim the bits ensure accurate hinge and hardware installation.
Made by Insty-Bit for Rockler to fit the hex-drive Insty-Drive system, this particular three-piece set allows you to drill holes for #4, #6, and #8 screws. The drill guide sits in the hardware’s screw-hole countersinks and aligns the bit for perfectly centered holes.
Insty-Bit makes these bits in the USA using precision-ground, high-speed steel. Rockler and Amazon are currently discounting this three-piece to $13. A heavy-duty nylon pouch to store the bits is included.
So, is it really that hard to drill a centered hole, or are self-centering bits the difference between fine furniture and something that looks like it was built in your garage? Let us know in the comments.
