PCD Reamer with Cylindrical Shank
Flexible holder setups where the machine and guide arrangement suit a cylindrical shank.
Request a QuoteMADE-TO-ORDER PCD REAMERS
Made-to-order PCD reamers for cylinder blocks, cylinder heads, valve bodies and other precision bores in non-ferrous and selected non-metal components. Each tool is developed around the bore requirements, guide concept, machine interface and coolant supply.
A PCD reamer is not a stock item. Each project moves from component review and tool concept to approved design, manufacture and inspection.
To Get Started:Share the component drawing, bore tolerance, machine interface and current machining issue.

SUNDI PCD reamers use polycrystalline diamond cutting edges to finish precision bores. Cylindrical, HSK, flange and BT shanks are available alongside drill-reamer, combination and guide-pad designs. The component drawing, machine interface and bore requirements determine the tool configuration.

Request a QuoteMatch the HSK interface to the spindle, gauge length and coolant requirements.
Request a QuoteFlange interfaces for projects requiring defined axial positioning.
Request a QuoteBT interfaces matched to the machining center and required gauge length.
Request a QuoteCombined drilling and reaming where the drawing and process support a single-tool operation.
View DetailsMulti-stage designs for related bore diameters when one-pass finishing suits the setup.
View DetailsGuide-pad designs for bores requiring additional guidance for roundness and finish.
View DetailsPrecision resharpening and PCD tip replacement are available for returned tools. The repair approach depends on the body condition, remaining PCD material and required geometry.
Precision Resharpening: Utilizing advanced grinding technology to restore sharp cutting edges and precise geometries.
PCD Blade Replacement: For severely damaged tools, we offer high-quality blade replacement and re-brazing services.
Performance after repair: Achievable performance depends on the condition of the returned tool and the remaining PCD material. Request an evaluation for your tool.
Repair options: Request a resharpening or re-tipping quote to compare repair with replacement for your tool.

Specify a PCD reamer when your process calls for finishing a prepared hole in an agreed non-ferrous or non-metal material. Share the bore diameter, tolerance, surface-finish target and any related datum requirements. If you are replacing a carbide reamer, include its current tool life and the size or finish problem you need to solve.
The tool design brings together cutting geometry, guide arrangement, machine interface, coolant delivery and stock allowance. Share the prepared-hole process, coolant supply and any chip-packing, taper or vibration problems. Tool inspection values describe the tool itself; the required hole quality must be defined separately on the component drawing.
Define the reamer design around the requirements of your application.

Prepare the tool body and chip grooves before assembling the cutting blades.

Cut the PCD disc into blade shapes ready for the next manufacturing step.

Join the PCD blades to the tool body in a vacuum brazing furnace.

Produce complex PCD cutting profiles using 5-axis Vollmer wire cutting.

Refine the cutting edge when the application requires a smoother hole finish.

Check the completed cutting geometry before handing the tool to quality control.

Apply the requested surface treatment and identification markings.


Feedback on our PCD reamers use has been extremely positive

CEO
★★★★★The PCD tools you have made have worked most excellently. Sundi solved a tooling problem for me that no one else would, I greatly appreciate that.

Purchasing Manager
★★★★★Last sample are working great ,We are rebooking them and already pay for 20 pcs cause we firmly satisfy with your item.
Send a PDF, DXF or STEP component drawing with material, bore dimensions and tolerances, surface-finish target, machine interface, coolant supply, stock allowance and your current machining issue. Include your contact details so our engineers can follow up on the application.
The bore drawing defines the required diameter, tolerance, surface finish and relationship to other features. Share the workpiece material, prepared-hole dimensions, guide arrangement, machine interface and coolant supply so we can develop the reamer for that setup. Tool inspection values describe the tool itself and are distinct from the finished-hole requirements. Our engineers offer this application review free of charge.
No. SUNDI PCD reamers are made to order for the component drawing and machine interface.
Lead time depends on tooth count, shank type, complexity and quantity after design approval. Manufacturing and shipping schedules are confirmed for the order.
Yes. Tool geometry is checked against the agreed specification before shipment. If you need an inspection report, confirm the required contents and delivery arrangements when placing the order.
Yes. Resharpening and PCD tip replacement or re-brazing are available for returned tools. The repair options and expected performance depend on the body condition, remaining PCD material and required geometry.
We are a direct tooling manufacturer, and T/T transfer is available. For the sample with a small amount, we can also accept credit cards, papal, western union, etc.
