CNC Drilling Parts
Custom CNC drilling covering through holes, blind holes and tapped holes ready for screws or bolts.

Product Overview
Custom CNC drilling covering through holes, blind holes and tapped holes ready for screws or bolts. The drilling machine spindle holds and rotates the drill bit, and computer control is what makes hole position and depth repeatable. Custom projects run through consultation, CAD design and prototyping, then production with quality checks on every component, followed by delivery and after-sales support.



Why Buyers Choose This Specification
Prototype Before Production
The design is modelled in CAD and a prototype produced so the component can be checked against expectations before any production quantity is committed.
Three Hole Types in One Operation
Through holes, blind holes and tapped holes can all be produced on the same setup, so a plate does not travel to a second shop to be tapped.
Every Component Checked
Custom components undergo quality checks against the agreed standard rather than batch sampling.
Consultation Before Quotation
Each custom project starts by understanding the requirement and the desired outcome, which is usually where a drilling specification goes wrong.
Where It Is Used
- Aerospace components where hole position is critical
- Plates and flanges requiring accurate hole patterns
- Blind holes for locating pins and dowels
- Tapped holes ready to receive screws or bolts
- Prototype parts checked before a production release
- Deep hole drilling in machined components
The Buyers This Product Suits
Aerospace Suppliers
Precision is paramount in aerospace components, and hole position tolerance is often the tightest requirement on the drawing.
Fabricators Needing Accurate Patterns
Drilled hole patterns that must match a mating part are where manual marking-out fails and CNC pays for itself.
Product Developers
Consultation, CAD design and prototyping are explicit stages, so a design can be proved before production starts.
What It Fixes
Holes That Do Not Line Up at Assembly
Computer control holds the pattern to the drawing rather than to the marking-out.
Parts Sent Out to Be Tapped
Tapped holes with internal threads are produced here, ready for screws or bolts.
Design Errors Found in Production
Prototypes are produced before production so the design is confirmed against expectations first.

How It Ships And What Comes With It
Packing And Loading
Shipping volume for this item depends on the configuration and capacity you select, so no fixed container figure is published. Confirm the specification and the destination and a loading plan is issued with the quotation, rather than a figure we cannot support.

Sourcing And Inspection
This product is supplied through TrueGlow Imaging, working with manufacturing partners whose facilities are visited and verified rather than taken on trust. In-process quality control and delivery supervision are available so goods are inspected before the container is sealed. Certifications quoted on this page are those stated on the product specification and belong to that product range rather than to our trading entity, so ask for the certificate covering your specific item.
Getting It Right First Time
Step 1
Dimension hole positions from the same datum the mating part uses.
Step 2
State whether each hole is through, blind or tapped, and give blind hole depth explicitly.
Step 3
Specify the thread and class for tapped holes rather than only the hole size.
Step 4
Request a prototype on any new pattern before production.
Step 5
Ask for the inspection record on critical hole positions.
How It Compares In Our Range
The three hole types and what each is for.
| Through Holes | Holes that pass completely through the workpiece, for bolts and fixings. |
|---|---|
| Blind Holes | Holes that do not go all the way through, for dowels, locating pins and partial fixings. |
| Tapped Holes | Holes with internal threads, ready for screws or bolts without a separate nut. |
CNC Drilling Parts Questions
What hole types can you produce?
Through holes, blind holes and tapped holes with internal threads.
How does a custom project start?
With a consultation covering your requirements, specifications and desired outcome, then CAD design and a prototype.
Do you make prototypes?
Yes. Prototypes are produced so the design can be confirmed before production begins.
How is quality controlled?
Every custom component undergoes quality checks before it is released.
What support is there after delivery?
Support continues past delivery, with a logistics network behind the delivery commitment.
Which industries do you supply?
Aerospace among others, where precision in drilled components is a primary requirement.
Sectors That Use This Product
