ABuff 4 inch 100 mm Hole Saw with Arbor, Heavy Duty 38mm Depth Bi-Metal HSS 4 Inch Hole Saw Blade with Positive Rake Teeth for Cutting Soft Metal, Drywall, Plastic, Wood, Fiberboard

I really liked this product well worth money

I cut the drywall with my 18V cordless drill which was a little clunky. Love the complete kit and ease of assembly. It would work better if I used the drill with a cord.

Was on time Well packaged Did a good job

Nothing

In todays market, finding the right tools for your DIY projects can be a daunting task. As an enthusiastic DIYer, I recently purchased the ABuff 4 inch 100 mm Hole Saw with Arbor, hoping it would live up to its claims of being a heavy-duty, versatile tool for cutting various materials. However, after putting it to the test, I regret to say that my experience was far from satisfactory. In this detailed review, I will share my personal experience, covering all the key points that make this product deserving of a dismal one-star rating. Product Description and Expectations: The ABuff 4 inch Hole Saw is marketed as a versatile tool designed for cutting through soft metals, drywall, plastic, wood, and fiberboard. The product claims to have a heavy-duty design, featuring a 38mm depth bi-metal HSS 4 inch hole saw blade with positive rake teeth. These claims led me to believe that the tool would be reliable, durable, and efficient across a range of applications. Build Quality and Durability: From the moment I unboxed the ABuff 4 inch Hole Saw, I was immediately disappointed by its build quality. The plastic handle felt flimsy, lacking the sturdiness I expected from a heavy-duty tool. Additionally, the arbor and hole saw blade appeared to be made from subpar materials, exhibiting signs of wear and tear even before their first use. These concerns about durability were quickly validated during my testing, as the hole saw blade began to lose its sharpness after only a few cuts, making the tool ineffective and unreliable. Performance and Cutting Efficiency: Despite its claims of being suitable for a wide range of materials, the ABuff 4 inch Hole Saw failed to deliver on its promises. Cutting through soft metals was an arduous task, as the blade struggled to make clean cuts and frequently got stuck, resulting in a jagged and uneven finish. When attempting to cut through drywall and plastic, the tools performance was equally lackluster. The hole saw blade exhibited excessive vibrations, leading to imprecise cuts and even causing damage to the surrounding material. In terms of cutting efficiency, the ABuff Hole Saw proved to be frustratingly slow and ineffective. Ease of Use and User-Friendliness: One would expect a tool like the ABuff 4 inch Hole Saw to be designed with user-friendliness in mind, but unfortunately, that was not the case. The handles ergonomic design fell short, lacking proper grip and causing discomfort during extended use. Additionally, the tools poor balance and excessive weight made it difficult to maneuver, further compromising its usability. The lack of clear instructions on how to properly use and maintain the tool was also a significant drawback, leaving users to figure things out through trial and error. Value for Money: Considering the disappointing build quality, underwhelming performance, and overall lack of usability, the ABuff 4 inch Hole Saw is undoubtedly not worth its price tag. It fails to deliver on its promises and does not meet the basic expectations one would have from a heavy-duty cutting tool. Investing in this product would be a waste of hard-earned money, as there are far superior options available on the market at similar or even lower price points. Conclusion: In conclusion, my experience with the ABuff 4 inch 100 mm Hole Saw with Arbor has been overwhelmingly negative. The tools poor build quality, inadequate performance, lack of user-friendliness, and questionable value for money make it deserving of its abysmal one-star rating. As a conscientious consumer, I highly recommend avoiding this product and exploring more reliable alternatives that offer superior cutting efficiency, durability, and overall value.

Cut well through siding to install new light and cut well through 2x4 to install electrical box. Is a true 4 inches unlike another product that advertised 4 inches but was actually metric and a few millimeters shy of 4 inches, made for a real problem when you tried to install a 4 inch duct.

It was needed.

The product is good quality and comes with multiple bits, however if you want to use it to cut sheet metal holes for HVAC holes this is not a good hole saw to use. Basically the bit just keeps enlarging the pilot hole and the saw itself just mars the surface. Ended up using a jigsaw following the mar the hole saw made. I suspect the teeth are too large.

This hole saw made installing a few dozen 4” recessed ceiling lights a breeze. I also used it to punch a hole for 4” round junction boxes. Those were done through 1/2” drywall. At first the holes were a little jagged because the drywall crumbled but I think that was my fault being cautious and taking it slow. When I went full-speed beast mode it punched through clean and precise. My husband used it on a 4” duct for the dryer vent going through 3/4” Zipboard exterior sheathing - clean hole, perfection. No complaints here!

I have used this type of hole saws for many years with varying success. This one did a GREAT job on the project that I was working on. I needed two holes cut, but a chest freezer is insulated and so 4 pieces of metal had to be cut and this saw went through the metal on the outside then through the insulation, and out the other metal side with ease. There was also copper tubing hidden in the insulation on both holes. This saw cut through all of this and the teeth remained sharp as new when the job was finished. ( Im making a fish smoker.
