Datron offers a line of edge radius tools that can machine a pristine radius along a workpiece edge or internally within a contour. These long-life, micro-grain carbide tools are available in various radii, shank diameters, and geometries for specialty applications.
From a slight .5mm radius to a larger 6mm radius, we offer a line of multi-flute cutters than can machine these types of rounded edges. The tools can machine in all three directions and provide excellent surface finishes. These tools are designed for aluminum, brass, plastics, exotic composites and any soft metals. They are not recommended for steel.
DATRON’s unique CNC cutting tools are made with a proprietary process:
$68.50 – $163.00
Article # | The number of cutting flutes in the tool determine how much material can be removed per rotation. For high speed, bulk material removal, single and double flute are recommended. Higher flutes will produce finer finishes, but may require a lower RPM than single flute mills. Flutes | D1 Nominal cutting diameter of the tool Cutting Diameter | D2 Shank diameter where the tool is in contact with the holder. D2 diameter can be too large for some machine spindles and smaller diameters may need an adapter to be used with spindles. Shank | D3= Toric cut diameter is the relief made above the cutting flutes on the neck to allow a tool to have longer reach when milling deeper features. Also known as extended reach. (D3) | L1 L1 is the total length of the tool from tip to base. Length | L2 L2 is the length of the usable cutting edge of the tool. This is only the flutes. Also known as flute length. This determines the amount (depth) of material that can be removed per pass. Cutting Depth | L3 L3= This is the overall reach a tool can be used. Flute plus any relief made by reducing the diameter in D3. AKA known as reach Reach | Radius of the cutting tip/nose. Edge Radius | Angle A= angle of a cutting edge. Drills, engraving tools and countersink tools aka point angle. A | Price | Availability | Size | Quantity | Add to cart | Waitlist | ||
