Achieve Flawless Flat-Bottom and Pocket Holes with Premium Woodboring Precision

Elevate your fine woodworking, cabinetry, and carpentry projects with the IRWIN Marples 8-Piece Woodboring Forstner Bit Set (1966892). Designed for uncompromising accuracy, these premium drill bits are engineered from exceptionally tough high-carbon steel to maintain a razor-sharp edge longer than standard bits. Whether you are crafting custom cabinets, installing concealed hinges, or creating precise pocket holes, these Forstner bits deliver impeccably clean, flat-bottomed (blind) holes without tearing the wood grain. The ultra-sharp cutting edges feature optimized angles specifically designed to slice smoothly through both hard and soft woods, providing a professional-grade finish right off the drill.

Beyond superior cut quality, the IRWIN Marples Forstner bits are built for efficiency. The optimized tooth geometry significantly reduces cutting time and effort compared to traditional Forstner bit designs, preventing burning and bogging down during heavy material removal. Each bit in this versatile 8-piece set features a reduced shank design, ensuring they fit perfectly into any standard 3/8-inch or larger handheld power drill or stationary drill press. Complete with a durable carrying case for organization and protection, this set provides the essential sizes needed to tackle almost any precision wood-drilling application.

Pro-Tip

When drilling large diameter flat-bottom holes with Forstner bits, always use a drill press set to a lower RPM if possible. Backing the bit out frequently to clear wood chips will prevent the high-carbon steel from overheating and burning the wood, ensuring a pristine, tear-out-free cut every time.

Nice Filter Wrench for my Volvo V70XC!
Size: 86mm x 16
I was needing a filter wrench for my 2001 Volvo V70XC and couldn't find anything that fit from the local auto parts stores. Not knowing what to expect, I took a chance on this one since most of the reviews were 5 star and the price was exceptional. When I received it, I was quite pleased with the construction and finish. I have a brand new oil filter housing for my Volvo (since the one currently on my car is chewed up from the former owner using slip-jaw pliers or something on it) and the fit is perfect! I have worked as a mechanic my whole life (aircraft & automotive), and spent a couple of years as a technician at an automotive dealership and I can say that the tool looks like it is designed for heavy-duty use. The stamped steel housing is thicker than those found in local auto parts stores and the drive adapter has a thick arc welded bead along the inside of the tool. So, it appears to be made to hold up to some fairly heavy torque. Although the product description states that it is 1/2", the drive adapter is actually made for direct attachment to a 3/8" drive. Perhaps this error stems from the fact that they offer a much larger wrench (118-131mm) and this is a more accurate description of their other offerings. The 3/8" drive adapter works perfectly and a 21mm socket fits nicely on the external hex. Fits with SAE sizes are a mixed bag, though. I was able to attach a 13/16" 12-pt. box-end wrench, but not the opposing open-end. A similarly sized 13/16" 6-pt. socket was extremely tight, so I wouldn't recommend this size and would just go with the 21mm if you had to use the external hex. Otherwise, just use the 3/8" drive adapter for easiest use of this tool. The adapter also incorporates ball detents on all four sides of the internal 3/8" drive, so your ratchet or extension won't easily fall off while in use. Since this tool is made for oil filter removal & installation, I'm sure that it will deliver as promised. I'll post an update after my next oil change and I get a chance to use it and install the new filter housing I have.
