Communicate with Our Bot

We are trying something new – utilizing a Messenger bot to walk customers through the drawing specifics. If you don’t have Facebook’s Messenger, download it now for your phone to be able to communicate with LeBlond’s bot.

We will announce the winners of the drawing in early March in a Messenger bot broadcast and the winners personally by phone and email. When you communicate with us in Messenger, make sure to include your phone number and email to be eligible for the drawing.

K.O. Lee Expanding Mandrels Page Makeover

We made some cosmetic changes to our Expanding Mandrels page.

We added a video and included charts showing sizes for general purpose and heavy-duty sets, so you don’t have to click through to the PDF on the bottom of the page to see what we have available.

What are K.O. Lee Expanding Mandrels & Why are They Needed?

K.O. Lee’s Expanding Mandrels are a time-tested workholding tool for grinding, turning and milling operations, often used on a mill or manual lathe.

Used in production lines, tool rooms and home workshops, these mandrels will hold work from thin sleeves and bushings to heavy castings and forgings. Our Expanding Mandrels are sized to fit 3/8” to 5-1/2” (9.5 to 139.7mm) holes.

The advantage of a full set of K.O. Lee Expanding Mandrels is that you will eliminate making and stocking straight arbors for every job.

Throughout the month, we will blast out content describing the other advantages of our mandrels.

Make sure you sign up for the drawing in Facebook Messenger to be eligible for three prizes including $1000 off an order!
