PROFESSIONAL GRADE DIAMOND PERFORMANCE FOR HARD MATERIALS

Drill through the toughest surfaces with precision using the Bosch 3-1/4 Inch Diamond Grit Hole Saw. Engineered with advanced vacuum-brazed diamond technology, this hole saw delivers superior cutting speed and significantly longer life compared to standard grit saws. It is the ideal solution for clean, crack-free drilling in hard materials such as porcelain, granite, slate, natural stone, and ceramic tile. The segmented tooth design reduces heat buildup and efficiently clears debris, ensuring a smooth finish and preventing the bit from binding during deep cuts.

Designed for efficiency on the job site, this accessory features an integral adaptor compatible with the patented Bosch Quick Change™ Universal Hole Saw System. This allows you to swap between different sizes and types of hole saws in seconds without needing extra tools. The design also incorporates specialized side slots for easy plug removal, so you can keep working without downtime. Whether you are installing plumbing fixtures or running conduit through masonry, this diamond hole saw offers the fast starts and durability required for professional applications.

  • Vacuum-Brazed Technology: Fuses diamond grit to the steel body for faster cutting and extended tool life.

Pro-Tip: Diamond grit saws perform best when kept cool. When drilling into hard tile or stone, use a spray bottle to apply water to the cut continuously. If you are drilling vertically, you can create a small "dam" of putty around the drill site to hold a pool of water, which will significantly extend the life of the diamond coating.

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.

Good deal for the price

The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil
