ENHANCED DURABILITY AND SPEED WITH M42 COBALT TECHNOLOGY

Upgrade your drilling performance with the Bosch HBT187 1-7/8 Inch Bi-Metal Hole Saw. Engineered for the toughest job site challenges, this hole saw is crafted from Bosch’s enhanced M42 alloy material, containing 8% cobalt. This premium formulation provides superior heat resistance and increases the tool's life by up to 20% compared to standard bi-metal saws. Whether you are cutting through wood, heavy-duty metal, drywall, or plastic, the HBT187 delivers clean, precise cuts time and time again, making it a reliable staple for electricians, plumbers, and general contractors.

The design of the HBT187 is packed with efficiency-boosting features. It utilizes the "Progressor" tooth design with a 5 TPI configuration to cut faster and stay sharp longer. The innovative triangle slot design on the side walls solves the common frustration of stuck plugs, allowing for quick and easy debris removal while also reducing heat buildup during operation. With a reinforced shoulder for added strength and a deep 1-3/4 inch cup to handle thick materials, this hole saw is built to take a bite out of any project.

Key Features

  • Enhanced M42 Alloy: Features 8% cobalt composition for high heat resistance and up to 20% longer life.
  • Triangle Slot Design: "Shark tooth" side slots allow for easy plug ejection and improved heat dissipation.
  • Progressor Tooth Geometry: Alternating tooth sizes (5 TPI) ensure faster cutting speeds and cleaner holes.
  • Deep Cup Capacity: 1-3/4 inch cutting depth easily handles 2x lumber, thick drywall, and multilayered materials.
  • Reinforced Shoulder: Adds structural strength to the base of the saw to prevent failure under high torque.
  • Versatile Application: Optimized for cutting wood, plastic, metal, and stainless steel.
  • Universal Compatibility: Works with standard hole saw arbors and Spinlock universal arbors (sold separately).

Pro-Tip: To maximize the life of your M42 hole saw when drilling through metal, operate your drill at a lower RPM and apply cutting oil to the surface. This reduces friction and heat buildup, which keeps the cobalt teeth sharper for longer. Use the triangle side slots to lever out the material plug immediately after cutting to keep your workflow moving.

Actually works on BMW!
I purchased this after the shorter black fluted tool I bought last year failed me. This thing is way better constructed, fits perfect , and actually works to turn it after you can’t turn it by hand any further. Was able to get torqued down to 25nm no problem finally with ease!

Nice piece but not for BMW motorcycles
Solid filter wrench. My bad for not checking the fit. Way too big for BMW filter 11 00 1 341 616 on my motorcycle. Turns out I had one that fits anyway. How dumb was that? I didn't get to try it on anything but four stars for appearing to be a good solid tool.
