Drag Face Blade Holders.
| The above photograph shows stretcher and header drag face blade
holders. The blades are 1/2" wide x 1/8" thick tungsten
carbide and have
a bevel down their long edges and can be reversed for maximum
life. The blade holders are mounted in a special frame bolted onto the front of the extruder which enables them to be angled to produce the desired drag effect.
