3/8" Dia x 1/2" CNC Solid Carbide Spiral Router Bit is a solid carbide router bit designed for CNC work where cut quality and tool life matter on demanding jobs. The bit is manufactured from exclusive ultra-fine micrograin carbide, which supports a sharp cutting edge for precise routing in aluminum cutting applications. A 3/8" diameter with 3/8" shank keeps the tool profile balanced for predictable performance in common CNC collets and setups. The bit is 3" long, giving working reach that suits many routing operations without overextending the tool. A 30 degree Center Cutting Mill End allows the tool to enter the material effectively for routing operations that start in the workpiece. The 2-flute configuration helps manage chip flow while maintaining a consistent cutting path along the tool edge.
This Amana Tool router bit uses a 3/8" shank, so it fits into collets designed to clamp that shank size, supporting secure mounting in CNC spindles. The 3" overall length gives room for typical stick-out while keeping the tool compact for stable routing. The up cut design means chips are directed upward toward the spindle area, which supports clear toolpaths in through-cut and slotting work. The 30 degree Center Cutting Mill End allows the bit to engage material as it enters, so it can perform routing operations that begin within the work surface. The 45 degree corner chamfer is positioned at the end mill area, where it adds edge strength that is important when the bit encounters heavier cutting loads.
This router bit is categorized under Bits, Blades and Cutters in the Aluminum Cutting class, so it is positioned for routing tasks that involve aluminum cutting operations. The ultra-fine micrograin carbide body supports detailed cutting work where edge precision is important on metal surfaces. The Aluminum Titanium Nitride (Al br TiN) coating is described as very important for superior cut quality, which supports applications where surface finish and reduced edge degradation matter. The up cut design pulls chips upward from the cut, which is valuable in aluminum routing because it helps clear chips away from the cutting edge. The 30 degree Center Cutting Mill End enables the bit to advance into the material while cutting, which matches workflows that start cuts inside the workpiece rather than only from an outside edge.
The 45 degree corner chamfer is identified as adding extra strength at the end mill, which directly targets the solid carbide end mill's number one major wear point and supports longer running performance. By enhancing edge strength at this stressed area, the design helps the bit hold geometry over more cycles, which is useful when repeatable results are needed across multiple parts. The combination of 2-flute configuration and up cut design manages chip evacuation, which supports consistent cutting loads along the toolpath. The 3/8" diameter and matching 3/8" shank give a balanced relationship between cutting size and holding interface, supporting stable engagement in CNC spindles. The CNC-focused description signals that the geometry and coatings are intended for controlled, repeatable passes in programmed operations where tool behavior needs to be predictable.
The router bit is listed in the Aluminum Cutting product class, so it is positioned for routing and cutting tasks involving aluminum materials in suitable setups.
The Aluminum Titanium Nitride (Al br TiN) coating is specified for superior cut quality, which supports cleaner edges and stable performance under demanding aluminum cutting conditions.
The 45 degree corner chamfer provides extra strength at the end mill, reinforcing the tool's major wear point and supporting longer service in repeated cutting operations.
The up cut design draws chips upward along the flutes, which helps clear the cutting area and supports consistent cutting action during routing passes.
The 30 degree Center Cutting Mill End lets the bit cut as it advances into the workpiece, supporting routing operations that begin within the material surface.
The bit is identified as a CNC Solid Carbide Spiral Router Bit, indicating its geometry, coating, and construction are aligned with controlled CNC routing workflows.
The Amana Tool 3/8" Dia x 1/2" CNC Solid Carbide Spiral Router Bit with AlTiN coating provides ultra-fine micrograin carbide construction, an up cut design, and a 45 degree corner chamfer to support aluminum cutting results. The 30 degree Center Cutting Mill End allows entry into material during CNC operations, and the 2-flute layout supports chip evacuation along the tool. For shops building aluminum cutting workflows around CNC router paths, this bit offers geometry, coating, and strength features that align with precise, repeatable cutting tasks.
