2-1/2" Tungsten Steel Concrete Hole Saw Kit with SDS Plus Shank and Pilot Bit
- 2-1/2" (65mm) SDS Plus Shank Tungsten Steel Concrete Hole Saw Kit
- Durable and fast, this hole saw can perforate through tough materials with ease. The male thread adapter design allows for quick and secure attachment to your drill, improving drilling speed and efficiency.
Unique Design:
The masonry hole saw blade is made from tungsten steel, making it thicker and sharper than ordinary blades. It can efficiently penetrate concrete up to 2-1/2" in diameter. The steel build ensures corrosion resistance and long-term durability, even under heavy use.
Crafted from tungsten steel and high-strength alloy, this hole saw kit is built to last. Utilizing high-frequency welding technology, the welding openings are strong, ensuring a smooth and durable cutting edge. The internal and external welding surfaces are well-finished for optimal performance.
Package Contents:
• 2-1/2" (65mm) Tungsten Steel Concrete Hole Saw. • 1x 8.66” (220mm) SDS Plus Connecting Rod.
• 2x 4.33” (110mm) Center Positioning Drill Bit. • 1x Screw
• Durable Construction: Made from tungsten steel and alloy. • Efficient Drilling: Triple-edged teeth and internal chip guides make drilling fast and clean. • Precise Results: The center drill bit and positioning screw ensure accurate and balanced drilling. • Versatile Use: Suitable for a wide range of materials and projects.
Pinpoint Precision:
Razor-Sharp Teeth:
- Triple-edged teeth design provides fast and efficient drilling, reducing the time and effort. The teeth are precisely engineered to handle tough materials.
- The 4.33” (110mm) center positioning drill bit ensures exact drilling, offering stability and balance during operation. This design reduces the risk of bit slippage and ensures clean, accurate holes every time.
- The internal and external grooves of the hole saw guide chips and debris outward, ensuring a smooth and clean drilling process.
Wide Applications:
- Perfect for a variety of masonry and construction projects, this hole saw kit fits SDS Plus shanks and works with most tools.
- Ideal for drilling through cement walls, stones, bricks, and foam. It is also a great choice for installing air conditioning units, oil fume extractors, and sewer pipelines.
- Usage Tips: Due to the hardness of materials, the hole saw may require a bit more time. For best results, use with water when working on high-hardness materials to minimize wear and extend the life.
Usage Tips:
1. Insert the center drill bit into the connecting rod.
2. Tighten the bit into place using the hex wrench.
3. Fit the hole saw onto the end of the connecting rod and screw it in.
• The center drill bit ensures drilling for precision. • Not suitable for marble, pebbles. • For drilling holes up to 100mm in diameter, use a 7A-9A SDS Plus rotary hammer drill. For holes larger than 100mm, switch to a 9A-13A drill. • Start with a lower speed to prevent tooth damage and ensure a smooth start.

The quality of this hole was seems good, I've only made a few cores through filled CMU and it did reasonable well. Price points on these vary widely with the higher cost ones featuring a dimond blade that'll cut through rebar. I don't think this product claims it'll do that and after limited use I don't think it would.It's durable enough to cut through block and other lightweight cementitious materials. I have some half inch fiber cement work coming up that I think this will work great for.FYI I use a DeWalt battery SDS hammer drill, a mask and used water to keep the heat and dust down during use. I think anyone who uses these would already know that but I thought it with mentioning anyway.Thank you and I recommend this product.

I am not a construction worker and I was trying to make a hole in brick. I was not succesful with my hammer drill but a neighbor gave me one of those heavy Millwakee ones. That made a lot of difference. I was able to make the hole pretty quickly and this holesaw is intact after the process. I am happy with it

Drill and parts come in plastic containers. They have a light coat of oil to prevent rust. Two drill bits are provided which are secured by a hardened set bolt. Hole saw is very heavy and teeth are sharp. It has a SDS plus shank for smaller rotary hammer drills.

I used this to drill a hole through a cinderblock wall for a PVC drain line using my Dewalt SDS Rotary Hammer Drill with dust collector. A dust collector is a must have. The shank of the bit is meant for an SDS drill and it fit my SDS drill perfectly.I let the tool do the work applying just enough even pressure to keep the bit moving though straight. I backed the bit out every half minute to clear debris and have a helper holding a shop vac hose under the hole use a spray bottle to heavily spray the bit and wall with water to keep the bit and hole saw wet. This helps keeps the bit/saw from overheating, which can quickly dull it. If you use too much pressure or fail to spray water on the bit for cooling, any hole saw will have a very short life. The water spray also helps with the dust control. But there is still a fair amount of fine dust, so wear a heavy duty N95 construction Dust mask as concrete dust is very fine.The hole saw is only deep enough to get about halfway through cinder block. From there I used another long SDS drill bit I had to drill the center pilot hole all the way through the wall. Once the pilot hole was through, I used it to center the hole saw and complete the 4½" hole from the other side of the wall. I ended up with a very neat professional looking hole for the pipe to fit through.The bit was perfectly centered, no wobble at all. Drilling this big hole went perfectly. This hole saw is priced low enough to get for a simple job like this, but I’m sure I’ll get more use out it if needed. The hole saw teeth can be sharpened with a file or grinder if needed to keep the cutting performance up and extend its life.

This is a good choice for a quick project, but I would not expect it to withstand heavy-duty jobs or repeated use. I would also make sure that there is no rebar or other metal in the concrete, as this will break on contact.Overall, its a good, affordable option for occasional or one-time use, but I would not rely on it for anything else.
