Plastic Drilling

What is Plastic Drilling?

Plastic drilling is a precision fabrication process used to create clean, accurately sized holes in plastic materials. It can involve standard drilling, countersinking, or counterboring – depending on the end use. At Dipec, we use pillar drills and specialist equipment to perform detailed drilling operations that complement and complete our other plastic fabrication techniques.

Whether it’s part of a bespoke prototype or a high-volume production run, drilling is often the final touch that ensures each component fits perfectly within its intended assembly.

Precision Plastic Drilling for Fabrication Projects

Plastic Drilling in Operation

Expert Plastic Drilling & Hole Finishing Services

Drilling is a critical stage in the high-accuracy fabrication of complex plastic components.
 
Our specialist drilling processes are designed to meet the exact tolerances of your technical drawings, providing:
  • Precision Mounting Holes: Accurately positioned holes for seamless integration into larger mechanical or retail assemblies.
  • Access & Ventilation Features: Clean-cut apertures for cabling, cooling, or internal component access.
  • Countersinking for Flush Fixings: Expertly tapered holes that allow screws and fasteners to sit flush with the material surface for a smooth, professional finish.
  • Counterboring for Secure Inserts: Cylindrical recesses designed to house bolt heads, washers, or threaded Tappex inserts for robust, demountable connections.

Integrated Fabrication Workflows

We don’t just drill holes; we integrate precision drilling into our full suite of services, including CNC machining, thermoforming, and line wire bending. This holistic approach ensures that every mounting point and access port aligns perfectly with your 3D profiles and formed shapes, delivering a final product that functions exactly as intended.

Plastic Drilling Process at Dipec

We review your drawings or CAD files to understand where and how each hole needs to be placed – factoring in use, fixings, and compatibility with other fabricated parts.

The plastic components are clamped securely, ensuring no slippage, cracking or distortion during drilling – critical for precise outcomes.

Using pillar drills, we create accurate holes, countersinks, or counterbores depending on the specification. Each pass is carefully controlled to avoid melting or warping.

All drilled parts are cleaned and deburred to remove residue and achieve a clean, professional finish ready for assembly or use.

A quality check ensures hole diameters, depths, and placements are to spec. Parts are then packed for delivery or continued fabrication.

Plastic Drilling FAQs

Plastic drilling is a fabrication process used to create precise holes in plastic materials using pillar drills or specialist equipment. It’s often used for assembly points, access holes, or mounting features.

Yes – when done correctly with the right drill bit, speed, and support, plastic can be drilled cleanly without cracking or chipping. Using specialist tools like pillar drills ensures a smooth, damage-free result.

A sharp, high-speed steel (HSS) drill bit with a shallow point angle (typically 90-118°) works best for plastics. Step drill bits and brad-point bits are also commonly used for cleaner holes.

It can if the drill speed is too high or if the bit isn’t sharp. At Dipec, we use controlled drilling speeds and professional equipment to prevent heat build-up and ensure smooth, clean holes.

Common plastics suitable for drilling include:

Dipec has experience drilling all of these and more.

  • Drilling creates a standard hole.
  • Countersinking allows screw heads to sit flush with the surface.
  • Counterboring creates a flat-bottomed hole for bolts or fasteners to sit below the surface.

We offer all three as part of our drilling service.

Yes – plastic can be drilled using a CNC machine for high precision and repeatability. However, for many applications, manual or pillar drilling is more efficient and cost-effective.

Yes – plastic drilling is one of our core capabilities and is often used alongside CNC machining, thermoforming, polishing, and wire bending to create complete fabricated products.

Yes, we can drill single components or small batches for prototyping, as well as high-volume production. Every project is tailored to your specific requirements.

Tolerances depend on material type and hole diameter, but in general, we achieve tight tolerances through jigging, precise marking, and controlled drilling techniques.

Absolutely. Once the thermoforming process is complete, we can drill accurate holes for fixings, ventilation, or access – ensuring they line up perfectly with your design.

Plastic drilling is widely used in:

  • Retail & POS displays
  • Engineering & manufacturing
  • Transport & aerospace
  • Medical & laboratory equipment
  • Education & public sector fittings

Yes – we provide countersinking and counterboring services to suit flush-mounted screws or deeper fastenings, ensuring a clean, professional finish.

It depends on the application. Drilling is more cost-effective for larger or deeper holes, especially in thicker materials. Laser cutting is ideal for high-precision or complex shapes, but may cause edge burn in some plastics.

Yes – after drilling, we can polish plastic parts to remove burrs, smooth edges, and improve aesthetics, especially on clear materials like acrylic.
