The CMT Solid Carbide Round Nose Bit is a precision-ground routing tool designed to mill smooth, semi-circular coves, decorative grooves, and ornamental flutes in wood and wood-based materials. Built from solid carbide (HWM grade) with 2 carbide-tipped flutes and right-hand rotation, this bit gives woodworkers the cutting consistency needed to personalize doors, drawer fronts, panels, and any flat or curved surface with delicate, repeatable accent profiles. With a 1/4 in. cutting diameter, 1/8 in. radius, 5/8 in. cutting height, and a 1/2 in. shank, it is sized for both handheld routers and router table setups where clean veining and cove work demand a reliable, durable tool.

Key Features

• Solid Carbide (HWM) Construction - the entire bit body is machined from high-grade solid carbide, delivering superior rigidity and edge retention compared to steel-bodied alternatives, so you get cleaner cuts over a longer service life in hardwood, softwood, and wood composites.
• 2 Carbide-Tipped Flutes - dual cutting edges distribute cutting load evenly, reducing vibration and producing smoother cove profiles with fewer tool marks, which means less sanding and finishing time after each pass.
• 1/8 in. Radius / 1/4 in. Diameter Semi-Circular Profile - the precisely ground round nose geometry creates a true half-round groove in a single pass, ideal for fluting columns, veining panels, and adding decorative accents to any wood surface without requiring multiple setups.
• 1/2 in. Shank - the full 1/2 in. shank provides greater shank surface area in the collet, reducing runout and improving stability during cuts, especially at higher feed rates on a router table or CNC machine.
• Right-Hand (RH) Rotation - standard right-hand rotation is compatible with the vast majority of routers and router table spindles, making this bit a drop-in fit for most existing setups without any configuration changes.
• 5/8 in. Cutting Height and 2-1/2 in. Total Length - the generous cutting height allows for deeper decorative grooves in a controlled pass, while the overall length provides adequate clearance above the collet for most router table and handheld router applications.

Why This Product

• For woodworkers who need consistent, repeatable decorative coves and grooves across multiple workpieces - doors, drawer fronts, and panel faces - this solid carbide bit holds its edge through extended production runs where carbide-tipped steel bits would begin to dull and produce tearout.
• The 1/8 in. radius profile is one of the most versatile sizes for decorative fluting and veining, striking a balance between fine ornamental detail and a groove wide enough to read clearly on finished cabinet doors and furniture panels.
• At 1/2 in. shank diameter, this bit is compatible with full-size routers and router table setups where vibration control and concentricity matter most, giving users the accuracy needed for tight-tolerance decorative work in hardwoods and MDF alike.
• Solid carbide construction throughout - not just at the tips - means the bit can be used in wood derivatives such as MDF, chipboard, and melamine-faced panels where abrasive materials quickly degrade lesser tooling, making it a single solution across a wide range of substrate types.
