1/2" Push Tool w/ Tungsten Poke
Push is suited to making indentations in glass. This heat-resistant tungsten pick tip can be adjusted in length. Tungsten Length Adjustment Procedure: You need to clamp the tungsten in a vise just tight enough to keep it from turning-pull and rotate the graphite back and forth slowly and gently (Don't pull/ rotate using the Wooden Handle). Alternatively, you can grip it with pliers and do the same thing. Maximum length 1/2". Make sure you pull very straight as the tungsten is brittle and will break before it bends. To make it shorter just push it straight against a piece of hardwood.
