The 4-Inch Hole Saw That Cuts Faster and Lasts 20% Longer

The Bosch HBT400 4-Inch Hole Saw is a professional-grade accessory built for speed, durability, and easy use. It’s engineered with an enhanced M42 alloy that contains 8% cobalt, allowing it to withstand high-temperature applications and deliver 20% more life than standard bi-metal hole saws. This is the ideal solution for plumbers, electricians, and remodelers who need to drill clean, fast holes in wood, metal, drywall, and plastic.

What sets this hole saw apart is its smart design. The Progressor tooth design features alternating teeth sizes that cut faster and last longer. A unique triangle slot design provides better plug removal efficiency and reduces heat buildup. Combined with a deeper 1.75-inch cup for drilling through thicker materials and a reinforced shoulder, this hole saw is built to perform, hole after hole.

Pro Tip

For the best results in metal, use a slower drill speed and cutting oil to maximize blade life. In wood, a higher speed will clear chips efficiently. The triangle slots are perfect for prying out plugs—just use a small screwdriver to pop the plug out from the side.

Simple, easy, and strong
Size: 16 Inch, Color: White
Kind of on the smaller side but for the price it’s just fine. Easy to install with just a screw driver if you can miss a stud, else you’ll need a drill. Strong enough to hold what a normal person would put on a shelf that size. No worries and it looks great

Good shelves for the price can be challenging to install correctly
Size: 16 Inch, Color: White, Size: 16 Inch, Color: White
Good quality shelves for the price. Happy with the purchase. They give you assorted hardware to mount each shelf. Wall anchors for masonry or brick and anchors for drywall as well as screws to affix shelf to the wall bracket. The installation was fairly easy but it can be a bit difficult to get the bracket leveled on the wall. The “level” they give you is useless, it is only the tube - not in a housing, so 1 1/2” long. You will need a better level. Basically you place the bracket where you want the shelf to go then make sure it is level and take a pencil to mark the holes. We ended up using a heavier quality wall anchor so only needed 2 anchors instead of the four they send you. Once the bracket is on, slide the shelf onto the bars coming from the bracket and use the 2 set screws to secure it in place. Check for level and if it isn’t you can remove shelf and loosen bracket screws and wiggle the bracket while still attached while retightening screws. We had to re-level one of our shelves this way. Hope this helps and that it makes sense. As for weight capacity I wouldn’t want to put more than a couple of pounds on a shelf. As it is secure, it is hollow inside and too much weight would probably either cause the shelf to sag or damage your wall
