New standard end mill delivers aggressive feed rates, exceptional stability and high-quality surface finishes
WAUKESHA, Wis. — Gorilla Mill has expanded its lineup of high-performance cutting tools with the introduction of the new 9-Flute Neanderthal, a high-efficiency finishing, and dynamic milling end mill engineered to remove serious material at aggressive feed rates while producing an exceptional surface finish.

Built for modern high-efficiency machining strategies, the 9-Flute Neanderthal puts more cutting edges in the cut to help manufacturers increase feed rates, improve chip-thinning utilization and remove more metal per minute. Its robust core geometry provides the rigidity and stability needed to minimize chatter and maintain consistent performance in demanding applications.
"The 9-Flute Neanderthal was developed for manufacturers that want to push productivity without sacrificing finish quality," said Nathan Cranker, Owner/President of Gorilla Mill. "When it's paired with the right toolpath and cutting parameters, this tool can make a noticeable impact on cycle times and overall throughput."
The tool is optimized for dynamic milling and finishing applications using lower radial engagement and high-efficiency toolpaths. Its nine-flute configuration allows shops to capitalize on increased feed potential while maintaining a smooth, stable cut.
Key benefits of the 9-Flute Neanderthal include:
- Increased feed-rate potential
- Nine cutting edges for greater productivity
- Improved chip-thinning utilization
- High core strength and resistance to chatter
- Excellent surface-finish capabilities
- Optimized performance in dynamic and high-efficiency milling applications
The 9-Flute Neanderthal is now available as a standard catalog offering, giving manufacturers access to a brutally effective productivity tool without the lead times associated with a custom solution.
"The Neanderthal is big, aggressive and slightly ridiculous in exactly the way Gorilla Mill customers have come to expect," added Nathan Cranker. "More importantly, it delivers where it counts: stability, productivity, surface finish and reduced cycle time."
