K.O. Lee Expanding Mandrels: Get Up to 20% off List Price on Mandrels


LeBlond Ltd., a supplier of LeBlond manual lathes, K.O. Lee equipment and OEM service parts, is offering a promotion until September 30, 2014 on K.O. Lee Expanding Mandrels. Customers can save up to 20% off list price or as much as $600 on Expanding Mandrels with ranges covering 3/8″ to 5-1/2″ for complete mandrels and individual arbors with lengths of 4-1/2″ to 15-1/2″ or sleeves from 1-14″ to 4-1/4.”

The mandrels bear the quality and superior workmanship consistent with the K.O. Lee brand, a subsidiary of the Cincinnati-based supplier LeBlond Ltd. LeBlond is part of a great machine tool tradition dating back as far as 1887.

K.O. Lee Expanding Mandrels are a work-holding tool for production lines, tool rooms and home workshops. A novice or veteran machinist can use a full compliment of these tools to reduce cost and the need to stock a separate mandrel for each job.

With the general-purpose sets of arbors and sleeves, you have five units ranging from the KMO to the KM4. These sets have a range of expansion from 3/8” (9.53mm) to as wide as 2 ½” (139.7mm). With the competition’s mandrels, a machinist might need to buy as many as eight sets to attain this range.

K.O. Lee Expanding Mandrels will hold work from thin sleeves and bushings to heavy castings and forgings. The tools are primarily used for grinding, turning and milling. The Expanding Mandrels are “Best-In-Class” and will hold work from thin sleeves and bushings to heaving castings and forgings.
