Our Wood Screw Countersink Drill Bits are shaped specifically for traditional wood screws with a tapered head, thicker shank and narrower thread. Note how the black countersink portion of the bit extends along the pilot bit to provide clearance for the shank of the screw. This allows you to enjoy the increased strength of screws with a thicker shank without compromising the grip of the threads. This 4-Piece Set includes bits for #6, #8, #10 and #12 wood screws.


Features:

  • Use for wood screws with the traditional thicker shank
  • 1/4'' hex shank for easy change-out with driver bits
  • Durable black oxide coating on countersinks
  • Pilot bits and countersinks are separable

Easy pilot hole and countersink for common size screws
A quick change pilot hole and countersink set for common wood screw sizes #6, #8, #10, and #12. A great time saver and they work well pre-drilling the pilot hole as well as countersinking for the screw head.

I purchased this set to replace bits that I have had for years and were getting quite dull. I was surprised at how much easier these bits cut. I like them and recommend them.

use these so the wood wont split while putting in screws and leaves the screws below the surface of your project makes it a better looking project when finished

Birthday gift for husband as advised by 2 of our talented sons. Retirement is giving the time to expand hubby's desire to learn more about woodworking. I see more purchases in the future.<br />The boyz advised to buy the best of often used tools and mid priced items for tools you don't think you'll need again.

Are replacement bits available in case the drill bit portion is damaged?
Gerald S on May 13, 2020
BEST ANSWER: I believe these will fit.
does the bit have a cutting edge to countersink the screw shaft and another for the screw head?
Tom M on Nov 12, 2018
BEST ANSWER: Yes, it drills a countersink hole for both the shank of the wood screw and the head.
Where are these manufactured? I'm not buying tools that are made in China!
Gary R on May 10, 2020
BEST ANSWER: They are made in the US.
Is the shank portion of the bit adjustable independent of the countersink?
Also are the drill bits standard?
Dave R on Apr 29, 2020
BEST ANSWER: The shank & countersink are machined as one piece, therefore no adjustment for that. What is adjustable is how far out the pilot drill bit extends, controlled by a set screw. The two larger drill bits are marked 1/8 and 9/64. The two smaller bits are unmarked, but measure .093" and .109" on a caliper.
Is this the appropriate bit if I intend to fill the holes with wood plugs?
Burton D on Mar 18, 2019
BEST ANSWER: As long as you match the size of the countersink to the size of the plugs, then yes. You might need to very lightly sand the outside of the plugs, and inside of the drilled hole, to get the proper fit.
How long do the bits protrude past the countersink head? I want to know the thinnest stock i can countersink into without breaking out the far side.
Matthew D on Jun 5, 2019
BEST ANSWER: About 1 5/8” from counter sink
