Solid Carbide Router Bits, 5/16" CD, 1/2" SH, 1-1/4" CL, Down Cut, USA Made Spiral Bit for CNC, Hand & Table Routers US4850D

Ultra-Shear 1/2" Shank, 2-Flute Solid Carbide Spiral Router BitsThe Ultra-Shear 1/2" Shank Solid Carbide Router Bit includes four cut lengths in 1/2" diameter—1", 1-1/4", 1-1/2", and 2"—along with three reduced cutting diameter sizes—1/4", 5/16", and 3/8"—each available in 1-1/4" cut length. These dimensions are offered in both Up-Cut & Down-Cut versions.Optimized for Various Routing SystemsWhether using a trammel, edge guide, router table, horizontal router system, or CNC machine, Ultra-Shear router bits provide exceptional performance. They deliver clean cuts and long-lasting tool life. These American-made bits are crafted with precision, using top-quality materials and state-of-the-art CNC grinding equipment.Reduced Cutting Diameter BitsThe reduced cutting diameter bits are perfect for clean cuts at smaller diameters. Ideal for dadoes, grooves, rabbets, and CNC machining, they provide excellent surface finishes on both sides and bottom of cuts.Specialized Bits for Mortise and Tenon WorkFor mortise and tenon work, especially through-mortise joints, the 1-1/2" and 2" cut length 1/2" diameter bits are indispensable. These bits offer generous cut lengths and are held to strict tolerances, making them perfect for CNC machines and horizontal routers.Choosing Between Up-Cut and Down-Cut BitsUp-Cut Bits: Ideal for dadoes, slotting, and full-edge cutting in solid wood, Up-Cut bits effectively pull chips out of the kerf.Down-Cut Bits: Perfect for rabbeting and working with cabinet-grade plywood, Down-Cut bits slice down into the material, preventing surface fibers from lifting.Made in the USAAll Ultra-Shear Solid Carbide bits are manufactured in Strongsville, Ohio facility. We use high-quality carbide blanks, ultra-fine grinding wheels, and advanced CNC grinding equipment to produce great American-made router bits.

• SOLID CARBIDE - This spiral 1/2" shank router bit with 5/16" cut diameter is made from a solid piece of carbide. We use state-of-the-art CNC grinding equipment, highest quality solid carbide blanks and ultra-fine grinding wheels to produce our American-made router bits.
• DOWN-CUT SPIRAL GEOMETRY - The spiral router bit down-cut flutes push chips down and away from the router, keeping the top surface smooth. They're the best choice for plywood and composite materials like MDF.
• CLEAN CUTS AT SMALL DIAMETERS - The reduced cutting diameter bits are ideal for dadoes, grooves, rabbets, and CNC machining. They provide excellent surface finishes on both sides and bottom of cuts.
• AMERICAN MADE QUALITY - Like all Ultra-Shear products, the 1/2" shank Spiral Router Bits are made right here in our Strongsville, Ohio, facility just south of Cleveland.
