The 4-Inch Hole Saw That Cuts Faster and Lasts 20% Longer

The Bosch HBT400 4-Inch Hole Saw is a professional-grade accessory built for speed, durability, and easy use. It’s engineered with an enhanced M42 alloy that contains 8% cobalt, allowing it to withstand high-temperature applications and deliver 20% more life than standard bi-metal hole saws. This is the ideal solution for plumbers, electricians, and remodelers who need to drill clean, fast holes in wood, metal, drywall, and plastic.

What sets this hole saw apart is its smart design. The Progressor tooth design features alternating teeth sizes that cut faster and last longer. A unique triangle slot design provides better plug removal efficiency and reduces heat buildup. Combined with a deeper 1.75-inch cup for drilling through thicker materials and a reinforced shoulder, this hole saw is built to perform, hole after hole.

Pro Tip

For the best results in metal, use a slower drill speed and cutting oil to maximize blade life. In wood, a higher speed will clear chips efficiently. The triangle slots are perfect for prying out plugs—just use a small screwdriver to pop the plug out from the side.

Just what I was looking for: Informative, clear, and concise
Format: Paperback
I've been looking for ways to learn about first aid beyond the basics of CPR and Stop the Bleed. This book is the best resource I've found so far. It is well organized, clearly written, and a pleasure to read.

Comprehensive wilderness medicine reference
Format: Paperback
First off, this book should be supplement to actual in-person first aid training and course work. I only have my background in Boy Scouts and work required first aid/cpr/stop the bleed response to base this upon. But there is no substitute for competent in-person and hands on training, even if you have excellent books for reference. That said, this book does have a very thorough guide on most issues that could be faced in wilderness and emergency situations. The cross over for urban use, would be situations like a natural disaster that renders hospitals and EMS unavailable or over capacity. It's a very affordable book for all the information it contains, and is published by a reputable school. NOLS has been teaching outdoors skills since it was formed in the 1960s. If you can keep a level head and have decent reading comprehension, this book lays out diagnostic and treatment advice for many life threatening injuries and accidents. I'd recommend this book to anyone looking to expand and supplement their knowledge beyond basic first aid and CPR.

Had an older edition and bought the most current edition. Very well written.
Format: Paperback
Classic text. Written at the college level. Text treats each topic initially from point of what are the causes of this injury, and how to prevent it. Then it goes into what will need to happen with an occurrence. No pictures, but that's a good thing. There are many drawings which do a better job of highlighting what is important.
