This #44 Parallel Flat GRS® C-Max tungsten carbide graver has two flat alignment areas on the shank of the graver. The set screws on GRS® QC Tool Holders will contact the flat spots of the graver, ensuring that the graver is loaded accurately. Saving you time and effort. C-Max gravers are made of a unique carbide with a metallurgical balance like no other carbide graver. Other carbide gravers break easily or do not hold a fine edge. This frustration is gone forever thanks to C-Max carbide gravers. Each graver has a 1/8" shank and overall measures about 2" long. Made in USA.
