Whiteside RU5150S Slow Up Cut Spiral 1/2"SH, 1/2"CD, 1-1/2"CL is a versatile router bit designed for cutting through hardwoods, plastics, and solid surface countertops with ease. Featuring a slow spiral design, it ensures better chip ejection in hard materials, while the up cut spiral provides a cleaner surface finish and excellent control for both hand and table routing. Made from solid carbide, this bit has a 1/2" cutting diameter, 1/2" shank, and 1-1/2" cutting length, making it suitable for routers with a 1/2" collet. The three-flute design allows for higher feed rates, boosting cutting efficiency and productivity, especially on CNC machines. Its upward cutting action removes chips efficiently in deep cuts, delivering clean, crisp edges and outperforming standard straight bits. I for both CNC and hand-fed operations, it improved cut quality with proper RPM settings, between 16,000 and 18,000 RPM, with a maximum of 24,000 RPM. Model Number: RU5150S
