Amana 46420 Solid Carbide Spiral Plunge 3/8 Dia x 1-1/4 x 3/8 Shank Down-Cut
Original price was: $95.15.$71.37Current price is: $71.37.
SOLID CARBIDE SPIRAL 3/8″ DIA.
Item Description
Spiral-flute bits combine a shearing action in cutting with an augering action in chip clearance. The shearing action yields an especially clean accurate cut while the augering action clears chips from the cut.
The ‘Down-Cut’ cuts from the surface down leaving a smooth edge at the surface.
Special unique carbide grade increased clearance geometry and razor-sharp cutting edges with polished flutes provide a superior finish and longer tool life especially in abrasive materials. Great for production settings and excellent for creating grooves and dado cuts in particleboard, plywood and laminate. Primarily used on CNC machines and other automatic routers. Can be used with handheld and table-mounted portable routers.

Amana Tool
Amana Tool® is an industry leader for over 40 years specializing in industrial quality solid carbide, insert carbide and carbide-tipped cutting tools for the woodworking, plastics, aluminum, composite and metal industry. They provide many solutions for manufacturers, fabricators, display and cabinet professionals as well as hobbyists. Amana Tool’s full line of industrial-quality cutting tools includes saw blades, router bits, shaper cutters, boring bits and much more.
Need This Tool Customized?
Every machining application is different. If this tool is close to what you need but not an exact fit, General Cutting Tools can help modify it for your specific job, machine, material, or production requirement.
We work with CNC shops, industrial manufacturers, tool rooms, and production facilities to provide tool modifications that improve fit, function, performance, and efficiency. Whether you need a small adjustment or a more specialized cutting tool solution, our team can review your requirements and recommend the best option.
Custom tool modifications can help reduce setup time, improve accuracy, extend tool life, solve clearance issues, and support more consistent production results.
Common Tool Customization Options
Diameter and OD Modifications
We can modify tool diameters to better match your application requirements, including cutting diameter changes, OD modifications, pilot diameter adjustments, step diameters, and shank diameter modifications.
Bore Modifications for Saw Blades
Custom saw blade bore modifications are available for hole diameter changes, pinholes, mounting holes, and keyway cutouts to help match your machine setup and cutting requirements.
Length Adjustments
Tools can be modified for specific reach, clearance, or setup needs. This may include overall length changes, flute length adjustments, reduced neck sections, extended reach designs, or shortened tools for improved rigidity.
Shank Modifications
Shank modifications can help ensure the tool fits properly in your holder, spindle, or machine setup. Common options include shank diameter changes, flats, Weldon flats, reduced shanks, and custom holding requirements.
Radius, Chamfer, and Corner Changes
We can customize corner radius, chamfer angles, edge breaks, and other profile details to meet part print requirements or improve cutting performance.
Step Tool Modifications
For applications that require multiple diameters or operations in a single tool, we can create or modify step tools to help reduce tool changes and improve production efficiency.
Flute and Cutting Edge Adjustments
Depending on the tool and application, flute length, cutting edge geometry, end cutting features, relief angles, and cutting edge shape may be modified to improve chip evacuation, cutting action, and tool performance.
Regrinding and Resharpening
Many cutting tools can be reground or resharpened to restore performance, extend tool life, and reduce replacement costs.
Custom Profiles and Special Forms
For unique part features, we can help provide special forms, custom profiles, custom radii, counterbores, countersinks, keyseat cutters, form tools, and other application-specific tooling solutions.
Material-Specific Tool Adjustments
We can help modify or recommend tooling based on the material being machined, including aluminum, brass, bronze, plastics, stainless steel, hardened steel, cast iron, composites, and other industrial materials.
Have a Drawing, Sample, or Part Print?
Send us your print, sketch, CAD file, photo, tool number, sample, or application details. For the fastest quote, include the material being cut, quantity needed, required dimensions, tolerances, and any machine or holder requirements.
Coating Options
Tool coatings can be selected or added to improve wear resistance, heat resistance, lubricity, and performance in specific materials such as steel, stainless steel, aluminum, cast iron, and high-temperature alloys.
