EXPERIENCE 2X LIFE AND PRECISION IN SHEET METAL DRILLING

Maximize your efficiency on the job site with the Bosch Edge™ HTW34 3/4 Inch Impact Tough™ Bi-Metal Hole Saw. Designed specifically for the rigorous demands of electrical, plumbing, and HVAC contractors, this tool delivers up to 2X the life of standard impact-rated hole saws. The robust 8-TPI bi-metal tooth geometry is optimized for cutting through sheet metal cleanly and quickly, ensuring dependability and value in every cut. Engineered to withstand the high torque of modern impact drivers, this hole saw allows you to power through tough materials without compromising on speed or finish.

The HTW34 features a convenient integrated one-piece design, eliminating the hassle of searching for a separate arbor or pilot bit. It is equipped with a built-in depth stop to prevent breakthrough, protecting work surfaces and ensuring precise hole depths every time. The integrated pilot bit spring automatically ejects plugs, significantly speeding up repetitive drilling tasks. With a 1/4-inch hex shank, this accessory offers universal compatibility with both impact drivers and standard drill chucks, making it a versatile addition to any professional toolkit.

Key Features

  • Extended Durability: Delivers 2X life versus standard impact-rated hole saws for long-term value.
  • Sheet Metal Optimized: 8-TPI Bi-Metal teeth are engineered for fast, clean cuts in thin-gauge metals.
  • Impact Ready: Built to handle the high torque of impact drivers for extreme performance.
  • Integrated Design: One-piece construction requires no separate arbor or pilot bit.
  • Safety Stop: Features a shoulder depth stop to prevent breakthrough and ensure accuracy.
  • Automatic Ejection: Pilot bit spring ejects plugs automatically for faster workflow.
  • Universal Fit: 1/4-inch hex shank fits all standard impact drivers and drill/drivers.

Perfect fit for our 2018 X5 35D
Perfect fit. Never replaced a filter in this car before and took me only 13 minutes. I timed it lol. That includes taking some before and after pictures from the old and new filter. What is worth mentioning is that the car was until now under the “fake maintenance” from BMW that comes with a new car and goes until 36.000 miles. Up to this mileage there is no other service the. The oil changes (3) due. The first real checkup is at a higher mileage and not covered anymore. Anyway , those filters where replaced before from a BMW dealership. When I compare the new filters and the filters I took out of the car they look the same. I was expecting to find some BMW marks on the installed filter but perhaps they don’t put their name in it anymore??? Or it could be they also put “after market” parts in. Anyway, BMW quoted me in all seriousness 700 dollar to replace those filters and the Inside filter The inside filter is on its way and is 25 dollar. Together with those filters the parts came to 55 dollar and I guess a total of 30 minute of work. Well done BMW, lol. We all need to make a living buy that should be considered “robbery” Anyway, if you thinking about replacing those filters then go for it. It’s not complicated and all you need is a screw driver to get one plastic river out that you can push back in once you are done. Those filters here from MANN are the real deal and fit perfectly and state that they are made in Germany. I have no reason not to believe it.

Excellent Product
It works really well. I used it on quarter tank and drove about 6 miles then filled up with top tier gas and my MPG went up by 3 miles on Highway and about 2 MPG city driving. At first there may be slight hesitation as it clears carbon. Then runs smooth as silk.

So far so good
It seems to be working well, so far. The check engine light turned off and the my vehicle seems to be running well. Be sure to follow the instructions. A while back, I wasted some money on a different catalytic converter cleaner because I put the cleaner in on a full tank of gas. It's best to wait until you're at a half tank or less of gasoline before you put in your catalytic converter cleaner. Also, I drove around right after I put in the catalytic converter cleaner and before I filled up my tank again. A couple of days later, I went to the gas station and topped off my tank. Again, it seems to be running well for now.

Works ok for some stuff.
I tried this mainly to clean my cats. It sadly didn't work for that at all. It did however work great as a basic fuel system cleaner. It smoothed out my idle and cleaned my O2 sensors they were a bit lazy before using this product now they switch fast like they are supposed too. In terms of my recommendation I say use as a fuel system cleaner. Or if your cats aren't too clogged in my case I bought an old neglected used car that likely had that problem for years. So I don't think any pour in tank cleaner would work in my case. However if your car just started having cat issues. This might work?? I think it's worth a try at least and isn't much more expensive than a basic fuel system cleaner so why not?
