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.

Smart, compact design gets the job done!
Size: 5 Ft, Color: White
I needed a compact power strip that I could wall mount behind my TV. Having both top and side outlets provided great flexibility to make sure the plugs didn't extend too far out and hit the back of the TV. And the plug of this strip is smartly angled so that it doesn't extrude far out of the wall outlet. If, like me, you're a DIYer who's a stickler for a clean, professional-looking installation, this power strip is essential.

A Powerhouse USB Hub That Handles Everything I Throw at It
Color: Gray
I’ve been using this 17‑Port 96W Powered USB 3.2 Hub for a few weeks now, and it has completely streamlined my workspace. With 10 USB‑A 3.2 ports, 2 USB‑C 3.2 ports, 3 QC 24W fast‑charging ports, and an SD/TF card reader, this hub truly replaces multiple adapters and dongles. The 10Gbps transfer speeds are legit — large files from my SSDs move quickly and consistently without random disconnects. The 96W power supply is a huge plus. Even with multiple external drives, peripherals, and a webcam connected, everything stays stable. No flickering, no dropouts, no “device not recognized” issues. The individual power switches are surprisingly useful too — I can turn off specific drives without unplugging anything. The build quality feels solid and premium. It doesn’t slide around, and it stays cool even under heavy load. The SD/TF card reader is fast and convenient for photo/video work. The QC fast‑charging ports are also great for topping up my phone or accessories, though they’re charging‑only (no data), which is clearly stated. If you’re someone who uses multiple devices — external HDDs, flash drives, cameras, microphones, card readers, etc. — this hub is a game changer. It’s perfect for PC setups, content creators, IT workstations, and anyone who needs serious connectivity. Overall, this is one of the most capable, stable, and well‑designed USB hubs I’ve used. Absolutely worth it.

Need lots of connectivity + charging. EXCELLENT.
Color: Gray
Problems with my original USB hub required something better. This unit has allowed me to connect all my peripherals to my laptop and I haven't had any problems with the USB port reliability I was dealing with. I'm using two hubs in series and now everything is working perfectly.

Yes, I wish I'd bought this on Black Friday, but still no regrets
Color: Gray
If you use a lot of add-ons like I do you won't regret buying this hub. The number of connection PLUS high power charging ports works for me. Printer, scanner, mouse dongle, phone, tablet, external drive, flash key all connect with zero problems to my Win 11 laptop. Saves my laptop ports from wear and provides a central location for charging my stuff. Solid metal construction, touch switches for each port, even slots forSDd and micro sd cards makes great design and features. Had a decent usb 3 hub but this one SO much better, good value

well made, nicely built, fast and everything fits firmly
Color: Gray
Sleek and well made, heavier than my old one, as it seems better built in every way. I love the flush power buttons, they don't get accidentally pushed in because of the firmness of the buttons, not hard, just not overly easy like some cheaper hubs. The color is nice looking, the lights are subtle but easily identify each port and the main thing, it's fast. My old USB hub was decidedly slow and often under-powered. It did not always work with some demanding devices. But as soon as I plugged this in, all my devices were recognized and worked correctly. This was a great buy.
