Chamfer & Roundover Router Bit Set — Sizes: 1/8" (3.17 mm), 3/16" (4.76 mm), 1/4" (6.35 mm); 5/16" (7.96 mm) — 6 mm shank Why this set helps you Precise edge profiles: chamfer and roundover shapes give clean, repeatable edges for finished work without extra sanding. Long-lasting performance: solid hardened 45# steel shanks with C3 micro‑grain tungsten carbide cutters resist wear and hold a sharp edge. Safer, smoother cutting: anti-kickback design plus a high‑tech grinding and advanced spray coating reduce chatter and produce a consistent finish. Versatile: suitable for edging, forming rounding edges, and cutting miter joints at various angles; works well for plunge cuts and pattern/template routing.
