Product Detail
Custom PCD Tooling for High-Accuracy Holemaking
Need PCD tooling for an aluminum bore? Start with a custom PCD reamer, then branch to combo or milling support. Send the drawing for an HENTRY RFQ.
Someone arrives with an aluminum bore print or a search for PCD tooling and expects a catalog reamer part number. Another visitor treats milling cutters as the main sell on this page and skips the bore decision. Neither path works until the print, material grade, and finish callout drive the first tool choice.
HENTRY custom PCD tooling is built around precision holemaking. For aluminum and non-ferrous bores, the first tool to define is a custom PCD reamer. Combination drill-reamers and PCD milling stay project support. Ferrous holes stay on solid carbide. Specs that are not on the print stay to your drawing.
Why PCD Tooling Starts with the Bore
On aluminum and non-ferrous programs, PCD earns its place when bore size, roundness, and surface finish have to hold across a release run. The inputs that decide geometry are the finished diameter, any steps or pilots on the same axis, the tolerance and finish callouts, the workpiece grade, and the machine and holder that will run the tool.
A stock catalog line does not carry those inputs. Edge preparation, diamond grade, guide-pad layout, coolant delivery, and shank length have to be set from the print and the machining condition. Faces, pockets, and profiles can share the same program later. They do not replace the bore decision when this page is the landing point.
Core Path: Custom PCD Reamers
For a high-accuracy aluminum or non-ferrous bore, start by defining custom PCD reamers. The reamer finishes size and surface after a controlled create pass. Typical seats include bearing and bushing bores, valve-body and transmission bores, EV housing seats, and other release aluminum holes where gauge acceptance depends on a stable finish cut.
Bore geometry comes from your drawing. Catalog part numbers are not sold on this page. Diameter, steps, diamond grade, guide pads, coolant path, shank, and overall length stay to your drawing and are confirmed in the drawing review. Empty standard-range tables are not pasted here.
Before manufacture, HENTRY agrees geometry, interface, and inspection points from the print and the agreed plan. Grinding and inspection for applicable PCD tools are documented on site. Workshop photos show grind and inspect resources; they do not by themselves prove a tolerance, a certification, or a tool-life result. See manufacturing quality evidence for how that process is framed.
Supporting PCD and Carbide Tools
Once the finish reamer path is clear, other tools can support the same program. The table below shows role only. Product links sit in the sentences after the table so each URL appears once on the page.
| Tool type | Typical use | Role on this page |
|---|---|---|
| Custom PCD reamer | Final bore size and finish in aluminum / non-ferrous | Core: start here |
| PCD combination drill-reamer | Drill and finish in one pass when the window fits | Holemaking extension |
| PCD milling cutters | Faces, pockets, profiles on the same program | Project support |
| PCD form / step tools | Chamfer, step, profile on the same bore | Project support |
| Solid carbide drills | Steel, stainless, cast iron where PCD is wrong | Ferrous holemaking |
When drill and finish can share one pass inside a controlled window, review combination drill-reamer options. For faces, pockets, and profiles on the same aluminum program, PCD milling cutters stay project support. Form and step features on the bore follow the same print review.
Materials This Page Will and Will Not Push to PCD
Aluminum, high-silicon aluminum, copper and brass, and many non-ferrous or composite stacks can be discussed for PCD when abrasion and finish targets justify the edge. Steel and stainless are not a PCD primary path on this page. Ferrous holes use solid carbide drills.
When the edge material is still open between diamond and carbide on a reaming job, read PCD reamer or carbide reamer. When one engineering partner must cover both PCD and carbide on the same program, start from custom cutting tools.
How HENTRY Frames Aluminum PCD Hole Finishing
Custom PCD reamers on HENTRY pages are framed for aluminum, high-silicon aluminum, and other non-ferrous parts. Steel and cast iron stay on solid carbide and other non-PCD holemaking paths on this page. PCD fits a stable non-ferrous bore where abrasive wear drives the tool change. Carbide fits steel, stainless, short runs, and setups that still chip the edge.
Aluminum pump bearing and bushing seats follow create-then-finish: open with a controlled create pass, measure the pre-hole, then PCD-ream when volume and abrasion justify the edge. That stack is written up on the NEV pump bearing hole PCD reaming page.
What to Send with the RFQ
Send enough detail for an engineering review of the bore and the machining condition. Incomplete packs slow the quotation turnaround.
- Component drawing or model with the bore or feature marked
- Material grade and condition
- Diameter, depth, tolerance, and required surface finish
- Machine, spindle interface, holder, and stickout
- Coolant type, pressure, and delivery path
- Current failure mode on the hole if parts are already running
Unsupplied diameters, steps, edge grades, and holder lengths stay to your drawing. Manufacturing and shipping lead times are not stated on this page. Life targets and percentage claims are not invented here.
PCD Tooling Questions
Which PCD tool should I start with?
Start with a custom PCD reamer when the job is a high-accuracy bore.
Do you sell standard PCD tooling from stock?
No. Tools are designed from the drawing and the machining condition through an engineering RFQ. Catalog part numbers are not sold here.
Can PCD run on steel or stainless?
Steel and stainless are not a PCD primary path on this page. Ferrous holes use solid carbide drills.
Do you also supply milling and forming tools?
Yes, as project support on the same program. They are not the first tool this page asks you to define.
How fast is a quotation?
Most drawing reviews are answered within one to two working days after complete information is received. That is quotation turnaround confirmed by HENTRY engineering. It is not a manufacturing or shipping lead time.
Send the Drawing
Send the drawing with the bore marked, the material grade, the tolerance and finish callouts, the machine and holder, and the coolant delivery. Specs that are not on the print stay to your drawing. The tool concept is reviewed from that package after the bore path is clear.
If a sample is the next step, use the sample validation process.
