Professional router bit set for woodworking milling and traditional joinery What's included - 1 tongue router bit (1/4 Inch shank) - 1 groove router bit (1/4 Inch shank) - 1 45 degree lock miter router bit (1/4 Inch shank) Key benefits — why you need this set - Accurate joinery: Tongue and groove cutters produce tight, repeatable joints for strong assemblies. The 45 degree lock miter creates seamless corner joints for boxed work. - Durable cutting edges: Blades are made from high-grade YG6X native alloy for extended edge life under typical woodworking conditions. - Robust construction and safety: Solid hardened steel bodies with anti kickback design reduce chatter and improve user control. - Reduced build-up and heat: Teflon coating resists resin build-up and helps dissipate heat, extending tool life and maintaining cut quality. - Common shank size: All bits use a 1/4 Inch shank for broad compatibility with most handheld and table routers that accept 1/4 Inch collets. Material compatibility and performance - Suitable for: density board, solid wood, medium fiber board (MDF), chipboard, plywood, and similar sheet goods. - Designed for milling, making joints, cutting grooves, and producing clean, repeatable profiles in the listed materials. Practical use scenarios - Drawer construction: Use the tongue and groove bits to cut mating edges for drawer bottoms and sides for tight, durable drawers. - Cabinet and window joinery: Cut grooves and tongues in plywood or solidwood panels for cabinet backs, window frames, and panel assemblies. - Box corners and picture frames: Use the 45 degree lock miter bit to create flush, interlocking 45° corners for cabinets, boxes, and decorative frames. Notes for use - Intended for routers with a 1/4 Inch collet. Match feed rates and router speed to material and bit diameter for best results. - The anti kickback design and Teflon coating contribute to safer, cleaner operation; always follow standard router safety practices and wear appropriate protection. Materials and construction details - Blade material: high-grade YG6X native alloy - Body: solid hardened steel - Safety/finish: anti kickback design; build-up and heat resistant Teflon coating This set provides the core cutter shapes needed for traditional tongue-and-groove and lock miter joinery, built for durability and clean, reliable performance across common woodworking materials.
