Original Groove
The geometry of the cutting edge is extremely complex. GME fully utilized its exceptional expertise during the restoration process to restore it to its original state.

Original Coating
The coating is crucial to tool performance. Only GME can utilize the original coating process.

Original Tolerances
The tolerances and quality standards followed during tool regrinding are the same as those used in the production of new tools. To ensure this, GME employs state-of-the-art measuring equipment.

Regrinding Scope
Regrinding scope: Solid carbide drills and end mills; solid carbide non-standard drills and end mills; high-efficiency solid carbide reamers; solid carbide thread end mills.

Tools are often prematurely scrapped, although GME can restore them to original factory quality, and may even restore them more times than they would have originally. You will benefit from lower costs, a more consistent machining process, and longer tool life. GME repair centers can restore your tools, saving you up to 50% on tooling costs!

The results of the tool life per piece (Life/pcs) for GME products and competitors show that GME products have an average tool life of 20 pieces, while competitors have an average tool life of 17 pieces, a lifespan increase of approximately 17%, fully demonstrating GME's significant advantages in durability and machining stability.

Carbide drills are widely used for drilling steel, and are particularly well-suited for machining high-strength steel, alloy steel, carbon steel, and tool steel. These drills are widely used in industries such as automotive manufacturing, aerospace, machining, and metal component production, and are particularly well-suited for high-volume production, high-precision machining, and high-load environments.
