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.

My new favorite summer sandal!
Size: 8.5, Color: Bay Fog
I am loving these shoes so far this summer! The color is so cute, perfect for a light summer palette. It's the perfect light purple that doesn't make me look pale or washed out. For reference, I have fair to light neutral skin tone. They are SO comfortable - a little too comfortable for a shoe, it's more comfortable than my ugg slippers! They do take a second to put on as you have to either force your ankle in without unstrapping the back - don't judge me - or undo them. Thankfully they have a strap to help get them on easily. I love these shoes. I am a medium width, but I think these have some wiggle room since both the straps are velcro and adjustable somewhat. They are easy to walk in, hold onto the foot, have been more balanced than some others I have had in this platform style, and are very cushioned to walk in. Slight arch support to me but I have somewhat high arches so if you are more flat footed or standard arch these will give you even better support. Really impressed with these. They are more casual but work with many different outfits from sundresses to jeans. For me, these were a great buy and I will be wearing them all summer.

Size: 9, Color: Sand
If I could give a Ten Star review, I would. Hands down the most comfortable pair of sandals I have ever owned. I wore them 16 days straight while touring Italy. Comfortable and goes with all of your outfits. They pack well in a suitcase too. Light weight.

Wonderful
Super comfy and easy on and off, yet stylish imo! I could walk miles in these as a 56 yo and have worn them for three years! I hope they never stop making them. The only tweek I would suggest is to cover the footbed with leather or suede not cloth so they would last longer!
