Drill bit Famag 40 mm carbide for plastic, cutting length 90 mm

Famag 40 mm carbide drill bit for plastic with a cutting length of 90 mm is a specialist drilling tool designed to produce clean, precise holes in a wide range of plastic and other non-metallic materials. The carbide tip and geometry are optimized to reduce melting, chipping and burr formation when working with synthetic boards, acrylics, PVC and similar substrates. The bit is suitable for both hand-held drills and machine applications where dimensional accuracy and tool life are important.

Advantages

The carbide cutting edge provides enhanced wear resistance and sustained sharpness compared with high-speed steel, enabling longer life when drilling abrasive or filled plastics. The 40 mm diameter and 90 mm cutting length give the capacity to create deeper holes in thicker panels without frequent tool changes. The tool geometry is adapted to minimize heat build-up and to evacuate chips effectively, resulting in cleaner hole edges and reduced post-processing.

Suitable for

• Drilling holes in acrylic sheets and plexiglass
• Working with PVC, ABS and other thermoplastics
• Coring holes in laminated panels and composite plastics
• Machine or hand-held drilling where consistent hole quality is required

Key specifications

• Material of cutting tip: carbide
• Nominal diameter: 40 mm
• Cutting length (GL): 90 mm
• Intended workpiece type: plastic and similar non-metallic materials
• Suitable for hand and machine use

How to use

Secure the workpiece and use an appropriate clamping method to avoid movement during drilling. Operate at a moderate spindle speed recommended for the specific plastic type to avoid melting—start with lower RPM and increase if chip formation indicates safe cutting. Use consistent feed pressure and allow the carbide tip to cut without forcing; backing support under thin sheets prevents breakout. Clear chips regularly and use coolant or air where applicable to control heat for extended tool life.

Usage recommendations

For best results, match drill speed and feed to the specific plastic: lower speeds for soft, heat-sensitive materials and slightly higher speeds for harder or reinforced plastics. Use backing or sacrificial material to prevent exit burrs, and inspect holes after drilling for any necessary deburring. Replace or resharpen the drill when signs of wear affect hole quality to maintain consistent performance.
