Product Description
The CMT 199.001.11 Solid Carbide Upcut Ball Nose Spiral Bit is a precision-ground CNC routing bit engineered for smooth 3D surface machining, relief carving, and sculpted profile work. Built from a special super-micrograin carbide formulation, this 1/8 in. diameter ball nose spiral bit delivers a keen, long-lasting cutting edge that performs across solid wood, wood composites, plastic materials, and laminates. The upcut spiral geometry shears material cleanly while ejecting chips efficiently, keeping the tool running cooler and extending edge life through demanding routing applications.
Key Features
- Super-micrograin carbide construction - produces and holds a keen cutting edge longer than standard carbide, reducing downtime for resharpening during high-volume CNC routing work.
- Low-angle upcut spiral design - shears wood cleanly and ejects chips efficiently, so the bit runs cooler and cutting edges last longer even in extended machining sessions.
- Ball nose (spherical tip) profile with 1/16 in. radius - generates smooth, continuously curved surfaces ideal for 3D sculpting, relief carving, and contoured profile machining without stair-stepping artifacts.
- 2-flute geometry - balances cutting speed and surface finish quality, making it effective for both roughing passes and finish passes on curved 3D surfaces.
- 1/4 in. shank diameter - compatible with a wide range of CNC router collets and handheld router collets, providing a secure, vibration-free grip during precision routing.
- Right-hand rotation - works with standard CNC router spindles and handheld routers, requiring no special toolholder configuration.
- Versatile material compatibility - suitable for cutting, copying, panel sizing, and general routing on solid wood, wood composites, plastic materials, and laminates, making it a single-bit solution across many shop tasks.
Why This Product
- The super-micrograin carbide formulation holds a sharper edge through more cutting cycles than conventional carbide, making this bit a cost-effective choice for shops that run frequent 3D carving or relief routing jobs.
- The low-angle upcut spiral was designed specifically to shear wood cleanly - meaning cleaner edges and smoother curved surfaces with less sanding required after machining.
- The 1/8 in. diameter combined with the 1/16 in. ball nose radius makes this bit well-suited for fine detail work in 3D relief carving and sculpted profiles where larger bits cannot reach tight contours.
- With a 1/2 in. cutting height and 2 in. total length on a 1/4 in. shank, this bit fits standard router setups while providing enough reach for layered panel work, curved surface copying, and panel sizing operations.

Frequently Asked Questions
What materials can this ball nose spiral bit cut?
This bit is designed for use on solid wood, wood composites, plastic materials, and laminates. It is suited for cutting, copying, panel sizing, and general routing applications across all of these material types.
What is the cutting radius of this ball nose bit, and why does it matter for 3D routing?
The bit has a 1/16 in. radius at the ball nose tip. This small radius allows the bit to machine fine detail in curved surfaces, relief carvings, and 3D sculpted profiles where a larger ball nose would leave coarser step patterns between toolpaths.
What is the difference between an upcut spiral and a standard spiral in a ball nose bit?
The upcut spiral direction pulls chips upward and out of the cut during routing, which promotes efficient chip ejection and keeps the cutting zone cooler. The low-angle spiral on this bit was designed specifically to shear wood cleanly while providing that efficient chip ejection, helping the cutting edges last longer.
Is this bit compatible with handheld routers as well as CNC machines?
Yes. The 1/4 in. shank is a standard size compatible with CNC router spindles, router tables, and handheld routers equipped with a 1/4 in. collet. The right-hand rotation matches standard router spindle direction.
