Onsrud Cutter LP (Libertyville, Ill.) has introduced Tuff Core Compression, a 0.375-inch/9.53-mm diameter CNC router tool made from a dual-grade carbide that incorporates a tough inner core for added strength and a wear-resistant outer shell for longer life when milling abrasive materials. The Tuff Core reportedly allows feed rates to be increased by up to 155 percent over conventional 0.375-inch diameter compressions. Higher yields are also possible — the manufacturer says standard 0.5-inch/12.7-mm compression tools can be replaced with the Tuff Core tool.
