Overview
CutStars solid carbide drills (GXD series for steels and cast iron, GSD series for stainless steel) are built for stable, high-efficiency hole making. Higher efficiency and stable machining for stainless steel and alloy steel, with less variation in hole diameter, quiet machining and good chip condition.
Key Features
- Ultra-fine grain carbide with J-type flute design and reinforced core — high rigidity and strong chip evacuation at low cutting resistance
- Self-centering 140° point angle for accurate hole position
- Dimensional accuracy within ±0.01 mm, with strict full-process quality control
- Field-proven tool life: in a wheel hub test in 55 steel, one drill finished 1,100 parts (68.75 m total drilling length) and raised machining efficiency by 28% — see our Success Case article
