Good quality, well made countersink drillbits. If I was going to purchase again, would only purchase #6 bit. The #8 and #10 take out to much material for use with #8 and #10 screws, if you want purchase in your top board or surface.

More well made quality Milwaukee tools. This Milwaukee Countersink set (Model 48-13-5003) includes three bits for common screw sizes (#6, #8, #10) with tapered bits and depth adjustable, 4-cutter countersinks/counterbores. The countersink head is held in place by opposing set screws, meaning two screws must be loosened/tightened when adjusting depth. There are flat spots on the bit shank for the set screws to press against, reducing the chance of bit slippage. Of course those flat spots aren’t present if the head is slid down the bit shaft to decrease depth. I never like using these type bits at less than full depth because the screws clamp down on the bits spiral edges, dulling the edge and allowing space for wood fibers to collect. Unfortunately that can mean extra long holes even when using short screws so depth adjustment is sometimes mandatory. These bits are no better or worse in that regard. Someone needs to design a high-quality, fixed-diameter, long shaft bit with flat spots and a 4-blade cutter head. While I found similar features on another brand’s countersink set, two things improve the Milwaukee set: the flat spot on the shanks and the etched size markings on the hex shank. In use, I found the 1/4” hex shank holds securely in a drill/driver, but it wobbles in use. In a chuck, the bits run true even at high speed. In both hard and soft woods, the bit advances slowly and tends to burn the wood, leaving charred fibers within the spiral grooves and between the countersink blades. The holes are fairly clean though, with little tearing in the countersink, especially when drilled at high RPM. I’ll never use the simpler single-cutter countersink bits again. The tapered bits are replaceable but I couldn’t find a ready source for them. I suspect other brands (or correctly sized straight bits) could be used in a pinch. These are good bits, though slightly more expensive than other high-quality, name brand sets. The cuts/holes are of similar quality, at least in initial use, so you pay extra basically for the markings and the flat spots.

Uniquely designed and useful drills for a large array of wood working projects. These counter sinks from Milwaukee have a unique design. The pilot drill bit is tapered down from start of bit to the tip which gives the screw more wood to bite into and the three cutting blades make countersunk holes smooth and clean. The quarter inch hex shank allows this bit to work in impact drivers while also helps prevent slipping in the chuck of drill/drivers. Having a set of countersinks in the three most used sizes of screws allows anyone from homeowners, DIYers to finish carpentry contractors to tackle any task/ project quickly and easily. with different size screws. I have used these countersink bits in pine wood with no major complaints aside from the occasional burning which could be due to the lousy lumber that is sold these days. When I used these bits to drill in laminated plywood each of the three different size countersinks made a clean hole whether just drilled that screw head was flush to surface or completely countersunk where a dowel, bung, or plug is put into hole. Each bit also has set screws that can be loosened to remove countersink head from shank for easier cleaning and bits can also be used alone to drill holes that do not need to be countersunk.

The rating given here for this set of countersinks is restricted to comparison of similar sets in this price range, which is where most handy persons budgets fit in. The bit length is adjustable and each countersink has two set screws, not just one. The drill bit tips are tapered so care should be taken to restrict side-to-side movement as they will break. The bits are sharp and drilling is quick up to the countersink. There is no actual stop so the depth of the countersunk holes can vary greatly. This is a handy set for the tool chest. The #6, #8, & #10 sizes should cover most applications.

A very well designed set of countersink drills.The 9/64th”, 11/64″ and 3/16″ set should cover most of you countersink requirements. The predrill for each is adjustable via the included 1/8″ allen wrench. The base is a 1/4″ hex shank that gives you the option to use it in your cordless drill or your quick change adapter. The size of the bit is etched on the shank albeit hard to read for old folks like me! Another find product from Milwaukee Tool.

Nice set of counter sink drill bits. I use for installing cabinets and other high end production where joining surfaces/face frames must be perfect
