Bringing It Back,
American Values.
The Glacern Modular Vise is made entirely in the USA, from the metal we use right down to the smallest nut and bolt. Every manufacturing process including machining, grinding, plating, powder coating, heat treating, etc. is performed right here in Los Angeles, California. At Glacern, we're setting a new standard and boosting American manufacturing - helping pros - hobbyists - and tinkerers realize their goals. Uncle Sam has never been more proud.
"The Glacern Modular Vise reflects our values and beliefs, it is who we are and what we stand for." -The GMT Team
Accurate Material Hardening,
Precision Grinding.
Each Glacern Modular Vise is hardened on the bedways and jaw plates to HRC 50-60 and our Cage Locks™ are also hardened to ensure maximum durability, longevity, and toughness. Your vise will stick with you through many years of machining and is built to endure. We precision grind all of our vises so that they'll be flat, smooth, and exact. Purchasing multiple vises? Ask our metrology team about our complimentary bedmatching service. We'll match your vises to within +/-0.0005"

Cast Iron Bar Stock
Every GMV Vise is manufactured from Dura-Bar, a ductile cast iron. It all begins with a water-cooled graphite die that is machined to form the shape of the bar. The die is mounted on a bar machine crucible, as the bar is pulled horizontally from the crucible, the head pressure feeds molten iron into the die, producing a fine-grained cast iron bar. This process enables the dense fine-grained microstructure to be free from shrinkage, gas holes and other inclusions, making it superior to carbon steel bar. The material also contains graphite in a pearlitic matrix which provides excellent wear resistance and vibration dampening.
