Engineered for Extreme Durability in Sheet Metal Applications
The Bosch HTWS Edge™ Impact Tough™ Hole Saw Set is built to withstand the rigorous demands of professional electrical, HVAC, and plumbing work. Delivering up to 2X the life of standard impact-rated hole saws, this set offers unbeatable dependability and value. Each saw features precision-engineered 8-TPI bi-metal teeth designed specifically for clean, rapid cuts through sheet metal. Optimized for today’s high-torque impact drivers, these tools allow you to harness maximum power without compromising on cut quality or tool longevity.
Convenience and precision are at the core of the Edge™ design. These hole saws feature an integrated one-piece construction, eliminating the need for separate arbors or pilot bits. The 1/4-inch hex shank ensures universal compatibility with impactors and standard drills, providing a secure, slip-free grip. Additionally, each saw is equipped with a shoulder depth stop to prevent breakthrough and damage to components behind the work surface, while the integrated pilot bit spring automatically ejects material plugs, keeping your workflow smooth and efficient.
Key Features
- Extended Lifespan: Durable design delivers 2X life compared to standard impact-rated hole saws.
- Optimized for Sheet Metal: Bi-Metal 8-TPI teeth geometry ensures clean, burr-free cutting.
- Impact Ready: Engineered to handle the high torque and speed of modern impact drivers.
- Safety Depth Stop: Integrated shoulder prevents over-drilling and protects materials behind the cut.
- Automatic Ejection: Pilot bit spring forces the material plug out immediately after the cut.
- One-Piece Convenience: Fully integrated design means no separate arbor or pilot bit is required.
- Universal Fit: 1/4 In. hex shank works seamlessly with high-torque impactors and drill drivers.

Good DIY Pipe Legs but Powder Coat Quality Lacks
Size: side table leg, Size: side table leg
These industrial style pipe legs make building a DIY end table easy and the kit saves a trip to the hardware store. The fittings go together normally and assembly is simple. Comes individually wrapped. My main issue is the powder coating looks and feels cheap and rubs off easily. The pipes already had marks from touching each other from unboxing. If you do not mind some wear on the finish over time this is a decent purchase. The metal at the hardware store will be thicker and more durable but will cost more. I’d recommend based on ease of having a kit and it being delivered saving me a trip.

Stable, attractive, and easy to turn into a table with your choice of top
Size: side table leg
The X-shape of the table legs - constructed with solid metal flanges, T-joints, X-joints and 1-inch diameter pipes - provides a strong and sturdy base for a wood top. The legs have adjustable feet pads to prevent scratches and ensure stability. Assembly of the legs is relatively simple (the instructions are clear) but you will need your own tools to attach a top.
The industrial design is especially well suited to rec room or finished basement use. I am adding a 28" diameter raw edge slab of wood from a recently felled tree as the top and it is very attractive. (Photo unavailable because after I made certain it would work I sent the slab out for drying and finishing.)
If you want a custom table and have a particular piece of wood you want to use, these legs are an excellent choice.

Very nice kit: Beware it is NOT heavy duty plumbing pipe though!
Size: side table leg
I want to give this kit a high rating, but I need to address the "truth in advertising" bit since there may be an important disconnect between what you think you are getting and what actually comes in the box.
Black plumbing used for shelving or table legs is part of an important niche in interior design. I like the industrial loft look myself and have a variety of glass, steel, and masonry elements in my home. This kit fits that look and provides plenty of "strength" for most domestic uses, like shelves or coffee tables. But they are NOT "industrial pipe" or "maximum durability pipe." Note the phrase "cast iron finish feet," which together with the other claims might lead you to think these are cast plumbing fittings. They are NOT!
The feet and flanges feel like electrical conduit fittings, and the pipe sections are likely aluminum. They might be electrical or they might be multi-use, lightweight pipe.
While all this might lead you to think that you're getting a truly retro, heavy-duty pipe kit made of black plumbing pipe, you are not. But, does it matter? Depends. I find the lighter pipe's smooth finish a nice "tone-down" from the rough plumbing look. All together, this kit provides plenty of strength for most furniture and the rustic pipe look, but with a nicer, lighter finish. To me that is a plus--this is a very nice kit and costs less that if you'd pieced it together from real plumbing parts (I priced it out to compare), and looks retro but cleaner. I knew what to expect because while I got this kit free on Vine, I had purchased a nearly identical kit from another seller last year.
So, I'm giving it 5 stars for what it actually is and for the price, JUST BE AWARE THE NARRATIVE IS MISLEADING. Which is unfortunate because just like some people might want the heavier pipe, I'm betting more would be attracted to the look with a cleaner, lighter feel.

Lovely and sturdy for what I needed!
Size: 3 Set 4-Tier, Planks Not Included, Size: 3 Set 4-Tier, Planks Not Included
We LOVE these shelving brackets! We were moving our books from our office space to turn that room into a nursery and I needed something that would be sturdy and off the floor since my books were moving to our living room. These are extremely sturdy, and also go with our curtain rods and other furniture that has this industrial style. The instructions for assembly are simple and easy to follow, I would just ensure you have an extra set of hands (this isn’t a one person job) we ordered the 3 pack, but ended up only needing the two for the space on the wall and they still hold the weight well.
Also this is a work in progress so please disregard that I don’t have the other two shelves here😂
Definitely a high quality and great looking alternative to some other brackets out there!
