Features

  • Depth adjustment does not require a wrench - It is an easy, quick and accurate tool to adjust the depth by turning the knurl by hand without a wrench. We made these woodworking tools in Korea; Ezenkorea adjustable depth countersink drill bit. And we have gotten a patent in five countries; the United States, Korea, Japan, China, and Taiwan.
  • To Prevent Scratches On The Surface - After processing the wooden hole, Ezen countersink bit only goes into a predetermined depth, so anyone can work stably. In addition, even if the drill continues to spin, the built-in stopper does not turn, thereby preventing scratches on the wood surface. This ezen countersink adjustable drill bit is the best product to drill diagonal and straight lines.
  • Quick Set Up The Wood Working Depth - Depending on the finishing depth of the screw work and the thickness of the wood, you can set the work depth as fast as desired. The hole depth of wood can be kept constant. This is an advantage of our product that cannot be found in other wood working tools and equipment.
  • Replaceable Center Bit And Body - To replace the countersink body or to reassemble the product after disassembling, rotate the retaining ring and connect it to the body. Then rotate until the marked line at the end of the ring is visible and align the bolt holes and marked line. Lastly, tighten the bolt. When you completely remove the set bot and then re-tighten, make sure to.
  • Outstanding Control Range And Depth - Compared to other companies, the stopper control range is longer. The stopper control range is 2.5mm (0 3/32 in) to 23.5mm (0 59/64 in). It is possible to work up to 39 mm ( 1 17/32 in) by separating the stopper and transforming it into a long type. Please use the standard 3mm and 4mm for the center bit. (Do not use products larger than 0.118"/3mm and 0.157"/4mm sizes.)

  • I was on the fence.
Style: 1/8"x5/16"(3x8mm)
I was on the fence about buying this because of the price but they kept popping up on different YouTube woodworking g channels so I thought, fine, I’ll try it. I was not disappointed and have used it extensively for the short period of time I’ve had it. If you are on the fence, hop off on the buy side. ... show more

  • Consistency
Style: 1/8"x5/16"(3x8mm)
I liked that it's easy to adjust and gives you a consistent depth without having to focus on every screw hole. I had about 500 screws to install and this saved me a lot of time. Works excellent for wood but can be problematic with certain plastics by debris binding up inside the guide.

  • Deceptive advertising.
Style: 1/8"x5/16"(3x8mm)
I expected two bits. You show a single bit in two positions. You don't make clear that it is a single bit. A simple 1 before adjustable countersink drill bit would fix that. You also claim that it doesn't need a wrench to adjust the depth, but I have got to loosen a set screw that requires an allen wrench. So how is this self adjusting? ... show more
