Dual Bearing Spiral Trim Router Bit – 1/2" Shank Paint-Blue Coated Woodworking Edge Trimmer with Top/Bottom Guide Bearings

Key Features

• Dual Bearing Precision: Equipped with upper and lower guide bearings for ultra-stable edge trimming, ensuring consistent depth control and reduced chatter on curved or straight edges.

• Spiral Carbide Blades: Helical cutting edges minimize tear-out and deliver glass-smooth finishes on hardwoods, laminates, veneers, and plywood.

• 1/2" Heavy-Duty Shank: Compatible with high-torque routers and CNC machines for demanding projects like cabinet door profiling or stair edging.

• Versatile Edge Guidance: Top bearing trims flush with the workpiece surface; bottom bearing follows templates for pattern duplication (e.g., sign carving, custom moldings).

Product Description

Engineered for perfection, the Dual Bearing Spiral Trim Router Bit redefines precision in woodworking. Its innovative dual-bearing system eliminates wobble, allowing you to tackle intricate edge profiles and large-scale projects with equal confidence. The spiral carbide blades slice through materials effortlessly, reducing sanding time and delivering zero-splinter finishes on delicate veneers or dense oak.

The vibrant paint-blue coating isn’t just eye-catching—it acts as a heat shield, protecting the tungsten carbide cutting edges from overheating during prolonged use. Whether you’re crafting custom moldings, trimming countertops, or replicating intricate patterns with a template, this bit’s dual bearings ensure unwavering accuracy. The 1/2" shank provides superior grip in high-powered routers, making it ideal for professional workshops.

Why Choose This Router Bit?
