CNC Machined Fixtures & Tooling
Custom Plastic Drill Jigs for Production and Assembly Lines
Plastic drill jigs position and guide drills during repeated hole-making operations. They cut setup time on manual or CNC equipment and hold hole location accuracy across batches of metal or plastic parts.
- Tolerance
- ±0.05 mm
- Lead Time
- 7–12 days
- Batch Size
- 1–500 pcs
- Axes
- 3 & 5-axis
How Plastic Drill Jigs Are Produced
Every jig starts from your 2D drawing or 3D model and follows a controlled sequence from material selection through final inspection.
-
1
Material Selection
We match the polymer to the required rigidity, wear resistance, and chemical exposure of your process.
-
2
CNC Milling
Blocks and sheets are milled on 3-axis or 5-axis CNC centers to the jig body geometry.
-
3
Drilling & Reaming
Guide holes are drilled and reamed to final diameter for accurate, repeatable drill entry.
-
4
Bushing Press-Fit
Bushings are pressed in where specified to extend jig life under repeated drilling cycles.
-
5
Edge Finishing
Chamfers and radii are applied to protect operators and avoid marking sensitive workpieces.
-
6
Final Inspection
Hole position, diameter tolerance, and flatness are verified before parts leave the shop.
Machining Capacity for Drill Jig Projects
We hold stock of common engineering plastics and run two shifts, so most drill jig orders move from order confirmation to shipment in 7–12 working days for quantities under 50 pieces.

Materials Commonly Used for Drill Jigs
Select a material family to see its service temperature, achievable tolerance, wear resistance, and typical use case. Each material sheet ships with traceability documentation.
POM / Acetal
Good dimensional stability and low moisture absorption for general fixture work.
- Max service temp
- 100 °C
- Typical tolerance
- ±0.05 mm
- Wear resistance
- Medium
Common use case: General assembly fixtures.
| Material | Max Service Temp | Typical Tolerance | Wear Resistance | Common Use Case |
|---|---|---|---|---|
| POM/Acetal | 100 °C | ±0.05 mm | Medium | General assembly fixtures |
| Nylon 6/66 | 80 °C | ±0.08 mm | Medium | Light-duty drill templates |
| Glass-filled PEEK | 250 °C | ±0.03 mm | High | High-temperature or chemical lines |
| PTFE | 260 °C | ±0.1 mm | Low | Corrosive environment fixtures |
| PAI | 250 °C | ±0.04 mm | Very High | High-volume production jigs |
When Machined Plastic Jigs Fit Project Needs
Plastic drill jigs suit prototype lines, low-volume equipment builds, and situations where metal fixtures would mark sensitive parts. They also serve as temporary fixtures while metal versions are tooled.
Because no mold is required, design changes can be incorporated between batches without extra tooling cost. Customers in automation and semiconductor equipment often start with one or two plastic jigs to validate hole patterns before ordering larger quantities.
Project Examples We Regularly Handle
- Locating jigs for mounting brackets on robotic arms
- Multi-hole templates for valve body drilling
- Insulation drill plates used in electrical enclosure production
- Wear-resistant guide plates for conveyor assembly stations
- Custom bushings pressed into POM bodies for repeated 6 mm and 8 mm drilling
