1/2" Shank 4-Flute Ball Nose T-Slot Router Bit for Woodworking, Door Frame Mortise & Tenon, Casing Grooving, Edge Trimming

This high-performance 4-flute ball nose T-slot router bit is expertly designed for wood grooving applications. Crafted from premium materials and advanced manufacturing techniques, it offers exceptional hardness, wear resistance, and corrosion resistance. Ideal for use with various woodworking machinery like trim routers and wood routers, this bit comes in multiple specifications to meet different cutting depth requirements. It is the perfect tool for creating grooves in door frames, mortise and tenon joints, and door casings.

Key Features

• Premium Materials: The cutting blades are made from YG6X tungsten carbide alloy, ground for sharpness, offering high hardness, superior wear resistance, excellent strength, toughness, heat, and corrosion resistance. The shank is constructed from high-strength 45# steel, resistant to deformation, and features a polished finish for enhanced corrosion resistance.

• Advanced Manufacturing: The blades are seamlessly fused to the shank via high-frequency welding, ensuring extreme joint strength. The router bit coating utilizes super-wear-resistant spray technology, providing a premium finish and excellent corrosion protection.

• 4-Flute Ball Nose Design: The four-flute structure significantly enhances cutting efficiency, enabling smoother and more precise grooving operations compared to standard bits.

• Multiple Size Options: Available in four cutting depths (2mm, 3mm, 4mm, 5mm) to accommodate various project requirements and material thicknesses.

• Feed Speed Reference Guide:

  • Disclaimer: Optimal feed rate depends on material, bit size, and desired finish. The following are general guidelines. Always prioritize a smooth cut and avoid overloading the bit.

Important Safety & Usage Notes

• For stability and precision, prefer bits with a larger shank diameter and shorter cutting length to minimize vibration and potential deviation.

• If the bit vibrates or wobbles during operation, STOP immediately. Re-install and tighten the collet securely, ensuring the shank is fully seated before resuming work.

• Always insert the shank completely into the router collet and tighten firmly to prevent shank breakage and ensure safe operation.

• ALWAYS wear appropriate safety equipment: Safety glasses, hearing protection, a face shield, and gloves are essential when operating power tools.

• STRICTLY FOR WOODWORKING ONLY. Do not use this product on metals, stone, or any non-wood materials.
