Flat Bottom V Groove Engraving CNC Bit for MDF, Acrylic and Plastic

The Flat Bottom V Groove Engraving CNC Bit is designed for engraving, chamfering, grooving, and edge detailing on suitable materials such as MDF, acrylic, PVC, and plastic. With a 90° V-shaped flat head and 6mm shank, it is suitable for CNC routing and engraving applications that require clean lines, sharp edges, and controlled cutting performance.

Made from carbide, the cutter provides good strength, bending resistance, and cutting stability during engraving and milling work. Its double-edged cutting design helps produce cleaner results while reducing material residue at the bottom of the cut.

This bit is a practical choice for sign making, decorative panel engraving, acrylic lettering, PVC board processing, and general CNC engraving work.

90° V Groove Cutting Design

The 90° V-shaped cutting profile is suitable for engraving sharp grooves, chamfering edges, and creating decorative line details. It can be used for lettering, pattern engraving, edge beveling, and shallow decorative cuts on suitable sheet materials.

The flat-bottom style helps produce a cleaner groove finish compared with standard pointed engraving bits, depending on cutting depth and machine settings.

Double-Edged Cutting Performance

The double-edged cutter design provides sharper cutting action and better balance during CNC operation. This helps improve cutting efficiency and supports cleaner surface results when machining MDF, acrylic, PVC, and plastic.

Proper spindle speed, feed rate, and cutting depth are important for achieving smooth results and avoiding melting, chipping, or rough edges.

Carbide Construction

Made from carbide, the bit offers good hardness, strength, and resistance to bending during cutting. This makes it suitable for regular CNC engraving and milling work where tool stability is important.

The cutter is designed for clean machining on compatible non-metal materials when used with correct CNC parameters.

Suitable for Engraving and Chamfering

This bit is useful for both decorative and functional CNC work. It can create chamfered edges, V-groove details, engraved text, patterns, and clean decorative cuts on signage boards, acrylic sheets, PVC panels, and MDF surfaces.
