SECURE AND STABLE HOLE SAW ATTACHMENT FOR PRECISION CUTTING

The Bosch HSBAL Standard Large Two-Pin Mandrel is the reliable connection point between your power drill and larger diameter hole saws. Designed for heavy-duty applications, this mandrel features a positive lock design where the hole saw threads onto the mandrel and is secured by two drive pins. This mechanism significantly minimizes wobble, ensuring cleaner, more accurate cuts and preventing thread stripping during high-torque use. It is an essential accessory for electricians, plumbers, and general contractors who require stability when cutting large holes.

Engineered for versatility and durability, this mandrel is constructed from high-speed steel to withstand the rigors of the job site. It features a robust 7/16-inch hex shank that provides a secure, non-slip grip in standard drill chucks. Compatible with hole saws ranging from 1-1/4 inches to 6 inches in diameter, the HSBAL fits all major brands, making it a universal solution for your hole cutting needs. Whether you are drilling through wood, metal, or plastic, this tool ensures your hole saw stays locked in place for maximum performance.

Key Features

  • Universal Fit: Compatible with hole saws sized 1-1/4 inches to 6 inches from all major brands.
  • Positive Lock Design: Two-pin locking mechanism engages the hole saw to minimize wobble and vibration.
  • Secure Shank: 7/16-inch hex shank prevents slippage in the drill chuck for consistent power transfer.
  • Durable Construction: Made from high-speed steel for long-lasting reliability in professional applications.
  • Standard Pilot Bit: Accommodates standard 1/4-inch pilot bits for accurate centering.
  • Easy Operation: Threaded connection allows for quick assembly and disassembly of the hole saw.

Pro-Tip: When using larger hole saws (over 2 inches), always use the drill's side handle to maintain control against high torque. Before engaging the drill, ensure the two pins on the mandrel are fully seated into the holes on the back of the saw cup to prevent the saw from locking onto the threads, which can make removal extremely difficult.

No show but stays on
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.

Favorite Socks Ever
Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

Great ankle socks that stay put at a great price!!
Size: 6-9, Color: Assorted
These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!

Great quality, no holes or fading!
Size: Medium, Color: Black/Assorted
I purchased these socks a couple years ago and love them so much that I just recently purchased them again! They fit perfectly, don't make my feet sweaty, and hit the ankle at the right spot. The material is so good that over years they have not faded and even though I wear the same few pairs every day, they have no signs of thinning or holes! These are the ONLY socks that I buy. I have the black ones as well as the multi-colored ones. I will never buy another brand or style again!
