GS9 Drill Bit Grinder — Dual-purpose geometry in one station

Step up to a grinder that handles both standard twist drills (2–13 mm) and DG/three-rake drills (≈3–13 mm) with point angles 90°–140°. The GS9 is designed for fast, precise regrinds with ≤0.02 mm repeatability, using high-accuracy collets, a diamond wheel, and a high-efficiency DC motor to deliver consistent, production-ready edges. Typical cycle time is about 10 seconds per drill after setup.  

Why shops choose GS9
    •    Dual-function flexibility: support for twist drills and DG three-rake drill geometries on one compact machine.  
    •    Tight tolerances: precise alignment and guided thinning for uniform chisel and lip relief (repeatability spec to ~0.02 mm).  
    •    Operator-friendly: quick collet swaps and intuitive guides keep training time low and throughput high.  

Best for: manufacturers who run a mix of standard and specialty drills and want one grinder that covers both without sending tools out.
