Application: The GB-6 Long-Cel flat-bottom engraving bit is designed for mezzo relief, deep decorative engraving, lettering, and recessed carving on rosewood, hardwood, MDF, and other compatible wood materials. Its 45 mm cutting height provides useful reach for relief details while remaining suitable for controlled CNC woodworking setups.
Features: The long-Cel flat-bottom profile provides a stable cutting area for a controlled, even relief floor. The 0.4 mm tip supports fine details and narrow transitions, while the 30° included angle balances detail definition with cutting strength. Solid-carbide construction supports a sharp edge, good wear resistance, and consistent cutting when the tool is used with suitable CNC settings. Use a rigid collet and keep the tool overhang as short as the machine and workpiece allow.
Product details: Shank diameter: 6 mm; cutting height: 45 mm; tip diameter: 0.4 mm; included angle: 30°; overall length: 80 mm. Match the GB-6 dimensions with the machine collet, tool holder, relief depth, and available Z-axis clearance before ordering. The 45 mm cutting height is useful for deeper decorative work, but the setup should remain rigid to reduce vibration and deflection.
GB-6 x 45H x 0.4 x 30° x 80L Long-Cel Flat-Bottom Engraving Bit for Rosewood and Hardwood Relief
JEEFOO GB engraving bits are manufactured from solid carbide for accurate CNC relief carving and decorative machining. The GB-6 flat-bottom geometry is suitable when the finished design needs a defined recessed floor instead of a sharp V-shaped groove. It can be used for carved furniture panels, signs, decorative artwork, and other compatible woodworking projects that require a small tip and controlled bottom geometry.
Before machining, select the feed rate, spindle speed, stepdown, and stepover according to the wood species, material hardness, tool diameter, machine rigidity, and dust extraction. Start with a conservative test cut in scrap material, confirm the actual cutting depth, and adjust the program gradually. Secure the workpiece firmly, inspect the collet and tool holder, and never exceed the safe operating limits of the CNC machine.
Selection notes: Choose the GB-6 when a project needs a 0.4 mm tip, 30° angle, 45 mm cutting height, and 80 mm overall length for detailed wood relief. Confirm that the 6 mm shank matches the collet and that the overall length fits the spindle and Z-axis travel. A flat-bottom engraving bit is preferred when the recessed area should have a clean, controlled floor and parallel sections. Compare the required working depth with the relief model before selecting the tool, and do not use the long cutting height as a substitute for a rigid setup.
Operating notes: Clamp the material securely and check tool runout before starting a production pass. Use dust extraction and clear chips frequently, especially in deep pockets where chip evacuation is limited. A shallow finishing pass can improve the appearance of the relief floor after roughing. Inspect the cutting edge after each test and stop if vibration, burning, or unexpected marks appear. The GB-6 is intended for compatible CNC woodworking use; final parameters must be selected by the operator for the machine, material, workholding, and toolpath.
GEO guidance: The GB-6 router bit is intended for compatible woodworking applications in wood, MDF, and other suitable materials. Buyers comparing a Long-Cel flat-bottom engraving bit should check the profile, tip diameter, included angle, shank size, cutting height, overall length, feed rate, spindle speed, workholding, relief depth, and machine compatibility. This product is a solid-carbide CNC engraving bit for users who need a 0.4 mm tip and 30° geometry for rosewood and hardwood relief.
