Rennie Tools - 4mm x 32mm Flute x 4mm Shank Solid Carbide O Flute Straight Router Bit / Single Flute For Plastic, Acrylic, Perspex Etc. 1F Cutter For CNC's.

• Full Dimensions Shown On The Second Image
• Single O-flute geometry delivers smooth, melt-free cuts in acrylic/Perspex (cast or extruded), polycarbonate, PVC, HDPE, UHMW, PE, PP, ABS, styrene, foam board, and other thermoplastics.
• O-flute design clears chips fast to reduce heat build up, helping prevent gumming and re-weld on plastics for a cleaner finish.
• The straight profile on this 4mm router bit offers stable tracking and predictable cutting—great for routing out profiles, slots, dados and for template work in sheet plastics.
• This carbide router bit is suitable for handheld routers and CNC machines

Engineered for precision, performance, and durability, these Solid Carbide Straight Single O Flute Router Bits are the ideal tool for machining plastics. Made from premium solid micro-grain carbide, these bits are designed for fast, free cutting and an exceptional surface finish. The single O flute geometry ensures efficient chip evacuation, minimizing heat build-up and preventing melting, even on challenging materials like acrylic or UHMW. The rigid straight design delivers low energy transmission into the workpiece, reducing deflection and improving edge quality. It is ideal for CNC and vacuum-forming applications where component rigidity and work holding can be difficult. Suitable for cutting: Polycarbonate, Polyethylene, Polypropylene, Polystyrene, PVC, Extruded Acrylic, HDPE, UHMW, and other hard plastics. Used extensively on vacuum-formed components and rigid plastic parts where precision and clean edge finish are required. Key Features Material: Solid micro-grain carbide for maximum tool life and wear resistance Geometry: Single O flute design for smooth chip evacuation and fast cutting action Cool cutting: Reduces friction and melting on thermoplastics Low deflection: Efficient energy transmission reduces load on work holding Applications: CNC routing, sign making, plastic fabrication, and vacuum forming
