GKM-2 Glass Knife Maker

Get Consistent, Controlled Breaks!

GKM-2 Glass Knife Maker Find Your Local Dealer

To achieve consistent, controlled breaks, two aspects of the breaking process must be measurably controlled: position and load. The glass position on the GKM-2 is controlled using precision micrometers. The load is controlled through the constant feedback displayed on the digital readout as the clamping handle and breaking arm are adjusted.

This Glass Knife Maker Controls Both Position and Load:
making it easy for you to achieve consistent, controlled breaks.

The GKM-2 is specifically designed to incorporate the “balanced break” method to produce optimum knife edges. Balanced breaks require equal lengths of glass on each side of the score, along with a mechanism that applies equal load to each side, resulting in a straight break. The GKM-2 also makes it possible to achieve consistent “slow breaks” desired by many users.

The rectangular shaped body of the GKM-2 is precision machined from a solid block of metal for long term stability and precision.

The instrument uses commercial size glass ranging from 6 mm (1/4”) to 12 mm (1/2”)
It has been engineered with mechanical stops for producing precise 25 mm glass squares with ease.

Micrometers for precise and reproducible alignment of 25 mm squares for diagonal breaks.

Includes locking mechanism for guides so micrometers can be removed after alignment.

Capable of producing knives with cutting angles of 35° to 55° using micrometer adjustments.
