Jig Boring for Accurate, Repeatable Holes
Jig boring is a finishing process that places precise holes at an exact location, size and depth. Unlike general CNC drilling or CNC milling, it runs on a specialized machine built to hold tolerances in the micron range.
At DEK, engineers use it for parts that need exact alignment between holes or identical dimensions across multiple units, in metals and plastics. It also reworks existing parts by enlarging or correcting misaligned holes, alongside our CNC boring services.
Why Engineers Choose DEK for Jig Boring
More than 2300 engineers work with us for hole accuracy, complex part capability and quotes reviewed by experienced engineers.
-
Exceptional Precision
Tight tolerances and micrometer-level control on holes, bores and alignment features give consistent fits that cut assembly time and rework.
-
Complex Geometry
Parts with multiple features, contours and tight spatial constraints, including angular bores and deep holes, handled with smart programming.
-
Reliable Delivery
Efficient workflow and flexible scheduling turn jig boring projects around in 4–7 days, with smooth global delivery when we say we will.
-
Cost-Effective Solutions
No MOQ, a no-waste approach and optimized setups keep costs under control, even for low volumes or complex parts.
Engineer-Reviewed Quotes
We do not use automated quote tools. Mechanical engineers with over 10 years of experience review every drawing, accounting for heat treatment deformation and tight tolerances, and quote within 6 hours.

Jig Boring vs. CNC Drilling and Milling
Choose jig boring when hole location, size and depth must hold micron-level tolerances. Compare the hole-making options in our guide to drilling vs boring vs reaming.
| Criteria | This ProcessJig Boring | CNC Drilling | CNC Milling |
|---|---|---|---|
| Best for | Exact hole location and size | General hole making | General milled features |
| Precision level | Micron range, ±0.005 | Less tight than jig boring | Less tight than jig boring |
| Hole alignment | Exact, repeatable | Less critical | Less critical |
| Choose when | Microns decide fit | Hole accuracy less critical | Holes are not the key feature |

Hole Features & Challenges We Solve
Jig boring handles hole types and part geometries where alignment, depth and surface quality decide whether an assembly fits.
-
Angular Bores
Angular bores on complex components, located with advanced equipment and smart programming.
-
Deep Holes
Deep bores held to exact size and depth with smooth hole walls; for long drilled holes see deep hole drilling.
-
Multi-Hole Alignment
Exact hole-to-hole alignment and true positioning, with less reliance on manual layout or custom jigs and templates.
-
Tight Spatial Constraints
Components with multiple features, contours and tight spatial constraints: the parts other shops find too challenging.
-
Tooling & Fixture Bores
Precise holes in Invar and tool steel tooling, frames and fixtures for demanding technical settings.
Common Challenges We Handle
-
Misaligned Existing Holes
Reworking or restoring existing parts by enlarging or correcting misaligned holes, bringing them back to the required fit and function.
-
Soft Plastics
PTFE and PE are soft; a specialized jig boring technique prevents distortion and tearing while delivering burr-free cuts and tight fits.
-
Heat-Sensitive Clear Parts
Heat build-up is minimized when boring PC parts, avoiding distortion or haze and preserving transparency on covers.
-
Hard Tool Steels
Hard tool steel is machined efficiently with excellent finishes for mold-making, stamping and tooling components.
Certified, Measured, Documented
Every jig boring job runs through the same certified quality system, from drawing to shipment.
