Tapered Ball-Nose Carving tools (CM304, CM404) - 1/4 in. (0.250 in.) Shank
Tapered ball-nose end-mills are the most commonly used cutters for deep CNC carving in wood, plastic and metal. Their tapered profiles make them much stronger than equivalent straight-wall tools while providing more flute volume for efficient swarf removal in deep, single-pass machining operations.
Of all the tapered ball-nose carving bits on the market, only PreciseBits cutters are:
- 100% measured / optically inspected to insure that EVERY tool meets, or exceeds, our published specifications
- available with depth rings precisely positioned to ±0.0015 in. (0.038mm), virtually eliminating the need for resetting Z-axis zero between tool changes (with bits of same overall length)
- made from premium grade submicrograin tungsten carbide (HRa 92, HRc 80)
Combining premium grade submicrograin tungsten-carbide, with guaranteed fidelity to industry leading specifications and our exclusive depth setting rings, produces tools uniquely designed for today's demanding CNC machining and CAD/CAM simulation environments. Combined with comprehensive customer support, our cutters have become the tools of choice for sign makers, model makers, artists and instrument builders around the world
