FTG USA Countersink Drill Bit Set 5 Pc #4#6#8#10#12 Tapered Drill Bit for Woodworking

Nice bits for drilling and countersinking at the same time. The tapered drill produces a hole that uses the whole screw to grab wood, not just the upper sides, and with the drill shaft engaged in the wood, the countersink hole doesn't chatter and looks great. The adjustability of the countersink head also allows for different length screws, but really short screws can be a problem - long screws just require drilling deeper with a longer bit after starting the hole. Extremely useful item, a real time saver, and seem to work well in pine, plywood, and MDF. Haven't tried them in hardwood yet, but don't anticipate any problems there, just clear the chips more often. I took a scrap piece of 2x4 and drilled holes to store the bits - use one size up, so the #6 drills a hole for the #4 bit, etc. They hold nicely and are easily accessible.

I’d buy this over the dewalt ones at the orange big box store any day. Cheaper prices and better quality. Dewalt one broke easily. I’m not sure why these things are so hard to find in stores. I build and install cabinets and this is a must have for the size screws we use. I have all Milwaukee drills so that should tell you I don’t settle for low quality and this is a real review. For this style and price range countersink this is the best I’ve found so far. Works well on melamine and plywood for me. haven’t used it heavily on hardwoods more than a few times but it went smooth the times I did. I’ve also be using it in my impact drill some of the time(and am more careful to keep it straight) And works great.

I bought these a few years ago, but recently started using them heavily. I broke two of the bits, so you have to be careful in tight spaces that you keep your drill straight. These are also good for drilling at angles. Others won't let you countersink at an angle

Does what it is supposed to do! Includes the sizes the yellow and red ones is missing! No problems so far!

Excellent tool. I’m definitely buying more. I like the durability and ease of use. Quality product. Did exactly what I needed. Fit my 1/4” impact perfectly. No wobble either. Cuts wood like butter.

Good bits for most soft woods like pine but do burn when drilling into hardwoods.

Work fine now in hard cherry.

I have been woodworking for over 40 years and have a lot of experience with drilling and cutting operations. I have many drill sets but my Combination countersink bits seem to walk off. I only have a couple with tapered bits, and they work well. My other countersink/drill bits allow the drill bit to slide inside the Shank. This style does not have a counterbore for relief of the screw Shank near the head. This style has a countersink that slides up and down the drill bit. I assumed that the pin they so proudly advertised to lock the drill into the hex shank was actually worth something. Nope, 27 holes and the bit came out of the hex Shank. I was countersinking holes in three quarter inch Maple veneer plywood. Do not go by the screw size description because these drill bits are larger than the hole necessary for a wood screw of their stated size. They advertise high speed steel, HSS, but these bits are not nearly hard enough to be considered a quality steel. There are many grades/types of HSS. They appear to be tin coated high carbon steel, HCS, but I don't have a hardness tester to verify that. The countersinks are not adequately sharpened. I could get past that because I sharpen my own cutting tools. I figured I would try something a little cheaper because the price was low enough that I could just toss them If they didn't live up to their description. I will be replacing these with something with better drill bits that has at least an M2 HSS rating.

The best I’ve found

Arrived safely, but when I tested it on hardwood, it got pretty hot. Which might be an indication of it getting dull faster

De verdad me gustaron mucho. Las brocas están muy bien afiladas y la pieza para el avellanado hace un excelente trabajo. Me gustó la posibilidad de recorrer la pieza grande a lo largo de la broca para ajustar la perforación al tornillo lo mejor posible. Al principio tuve la impresión de que las brocas eran demasiado gruesas, ya que usas cualquier broca del kit se entiende por qué. El vástago hexagonal de ajuste rápido funciona súper bien con llaves de impacto pero es demasiado ruido, prefiero usar el taladro. Estoy muy satisfecho con el producto.

Works as they should

They drill very well and screws grab nicely in the tapered pilot hole. Excellent product
