Experience precision and efficiency with the Amana Tool Countersink Bit including a slow spiral, High-Speed-Steel (HSS) M2 fully ground drill bit. This countersink drill bit set for wood, acrylic, and aluminum is designed for long-lasting performance. Engineered with an adjustable, heavy-duty revolving depth-stop and a strong no-thrust ball bearing, this tool allows for quick and easy countersink depth adjustment without scratching or burning the work surface. The open space design ensures effective chip evacuation during use, keeping your workspace clean and your bit running cool. The user-friendly design lets you control the drill length and easily replace the bit—without removing the depth stop. Please note: When drilling aluminum/non-ferrous materials, for optimal results and extended tool life use lubricant or air cooling. Make sure the material is fixed and the drill is stable during drilling. Disconnect from any vacuum system. Using Low RPM is recommended.

    • Extremely useful and a time saver!
Size: 3/8 D x 1/8 Drill D x 1/4 Inch
The tool is very well made, high quality and a joy to use. Precise adjustment and uniform quality of results, and a huge time saver for consistent screw sets. Pricey, but delivers what it promises, and you will probably only ever need one.

I fall for alot of gadgets - most don't live up to the hype, or they just flat-out suck! But THIS little thing? Absolutely awesome! It makes every countersink hole perfectly consistent. It's simple, effective, and honestly just makes me so happy every time I use it. Totally worth it! (Imma buy more before they yank up the price ;) ... show more

    • Probably the best countersink for wood screws with a hand drill
Size: 3/8 D x 5/32 Drill D x 1/4 Inch
I've only used this for a few holes, but thought I would share my initial opinion. I've used several countersinks on wood screws and I'm primarily concerned with how smooth the outer edge of the hole is and how repeatable the countersink depth is. I have tried the Snappy, the cheap Ryobi, and a few others. The best I have found until now are sold by Lee Valley and made by an Israeli company. With this product I obtained clean holes with no edge breakout on pine plywood. I looked at the package and it says "made in Israel". I suppose Amana has a deal with the same company. I did not test counterboring as you would for a plug covering the screw. No scratching of the surface as the collar does not rotate. If you adjust the depth stop, you have a perfect hole that just fits the screw head every time. The only downside to this product is that the collar completely blocks your view of the progress of the countersink. You are drilling blind at this stage unless you can move your head down to see under the workpiece. Just takes some getting used to. The depth is controlled by the collar, so you don't really need to see what's happening. You do need to really slow down the drill as the countersink portion is engaged. In general, countersinks like to cut slow if you want a smooth edge. I try for about 200 RPM for a countersink of this size. If you don't want to spend the money on this, a pretty good hole can be obtained with the Ryobi set AFTER you hone both sides of all the cutting edges. An Ez-lap or similar DMT tool or small sharpening card is good for that. (and they are diamond grit, so they will also sharpen this countersink if you drill enough holes to dull it) This countersink product series includes several drill diameters. This one will clearance drill for the threads on a #8 modern wood or deck screw. Consider the screws you are going to use and whether they have a relieved shank that will extend through the top workpiece. I will probably buy a 1/8" one for that case. Also, I learned that wood screws, at least the GRK brand, are 90 degree heads. Sheet metal screws and machine screws to imperial (U.S.) standards are 82 degrees. Machine screws for very thin parts (aircraft or electronics sheet metal) are sometimes 100 degrees. Amana offers 82 and 90 degree versions. If you are using a drill press, very good results in wood can be obtained with a machinist's zero-flute Weldon countersink set. They are HSS and must be sharpened occasionally with a small stone in a moto-tool or die grinder. Those will not counterbore for a plug, only countersink. Machinery suppliers also sell one-flute countersinks that will do pretty good, and solid carbide countersinks. Hand drilling with the common six-flute hardware-store countersinks either leads to burning through the wood since they are not sharp, or more commonly wobbling in the hole and chattering. If you've read this far, you are now a countersink expert... Edit: If your collar is turning after contact, try light machine oil under the retaining ring. Made a difference for me. ... show more

As noted by other reviews the bit and bushing are well made and preform great, the issue of marking and marring of the work surface is easily avoided if you don't mash down when drilling, the bit is sized perfectly for #8 screws. Only point of contention is the Allen key that came with it snapped after the first use when adjusting the hight. ... show more

    • Saves time and produces accurate counter sink for screws and holes for plugs.
Size: 3/8 D x 1/8 Drill D x 1/4 Inch
Great tool to drill and counter sink to the same depth every time. Saves time. The stop doesn’t mark the wood surface. The drill is short but it’s easy put a longer one in when I need to go through thicker wood.

    • Awesome countersink
Size: 3/8 D x 1/8 Drill D x 1/4 Inch
It took me a long time to decide to pay a significant amount for a countersink bit and I am glad that I finally did! This bit is great. Easy to adjust and cuts nice countersunk holes. The bearing system to stop the height adjustment from rotating with the bit when it contacts the wood is smooth. No marring of the wood surface and provides a consistent depth each time. Great product! ... show more
