Our jig grinding team takes pride in making parts to critical dimensions — accurate to within one ten-thousandth of an inch, what machinists call a “tenth.” We understand that your work needs to be square, parallel, and finished to spec. Toolrite’s employees are highly skilled, with years of hands-on jig grinding experience that give them the ability and proficiency to make your parts right.
Flexible Part Capacity
Our five Moore jig grinders provide the range and flexibility to handle a wide variety of part sizes. Each machine is paired with an extensive on-hand supply of wheels and mandrels — keeping lead times short and efficiency high.

Extensive Grinding Wheel Inventory
Just like a toolbox needs the right wrench for every job, jig grinding requires the right wheel for every material and application. We stock a comprehensive inventory so we can match the wheel to your specific requirements.
CBN / Borazon Plated
Steel shanks in an assortment of grits. Ideal for mild steels through hardened tool steel.
Impregnated CBN
Carbide shanks with a variety of bonding materials and grits.
Diamond Plated
Steel shanks in assorted grits. Used for carbide, ceramic, and specialized materials.
Impregnated Diamond
Carbide shanks with varying bonding materials and grits for specialized work.
Stone Wheels
Different grades, hardness, and grits. Easily dressed to match complex radii and angles.
Carbide Burrs
Designed for softer materials like aluminum and bronze.
Wheel Dressing
The process of touching up and sharpening the abrasive surface of a grinding wheel before use. Dressing removes undesirable particles and smooths the surface, ensuring the component being ground receives a satisfactory finish.
Precise Part Support
Having the right tooling to hold and support parts during grinding is just as critical as the grinding wheel itself. Our workholding setup includes motorized rotary tables for chamfer angles and taper holes, along with 3-jaw chucks, magnetic chucks, V-blocks, and custom fixtures to keep every part locked in place.
As a full-service tool & die shop, we can fabricate any custom fixture we need in-house, allowing us to accept complicated work that other shops aren’t equipped to handle. These fixtures can be attached to master sine plates to ensure parts are ground to the precise angle required.
From Start to Finish, Under One Roof
Toolrite is a complete manufacturing facility. Whether your job starts raw or arrives partially complete, we have the departments and expertise to see it through, including vendor coordination for any services that extend beyond our walls.
Located in southeastern Wisconsin, Toolrite also maintains strong relationships with regional vendors for heat treating, gear cutting, and finish coatings. We manage all logistics between facilities, so you receive the final, complete product.

Quality Assurance
Quality is fundamental to everything we do. Since jig grinding demands extreme precision, we use a robust set of inspection tools, both on the floor and in our quality lab, to confirm every part is made to print.
- Deltronics Pin Gages
- Bore Gages
- Micrometers
- Depth Gages
- CMM (Coordinate Measuring Machine)
- DCC CMM (Direct Computer Controlled)
Inspection reports are available upon request, including simple reports, PPAP reports, and Cpk (Process Capability Index) studies. Our quality management software ensures accurate, repeatable documentation — especially valuable on larger production runs.
Frequently Asked Questions
We love a good challenge! From plates with tapered holes to nozzles requiring tight-tolerance chamfers, our team has the skill to get it done. We’re happy to discuss your job and troubleshoot the best path to completion.
Yes, either is fine with us. We understand that outside diameter (OD) jig grinding is often critical for shafts, pins, and crankshafts. We’re equally equipped for internal diameter (ID) jig grinding, commonly used for bearings, gears, bushings, and sleeves.
No problem. We don’t mind one-piece orders. Our agile scheduling makes it straightforward to fit single-piece jobs into the queue without delay.
We can handle that too. Send us your request for any quantity and we’ll have an honest conversation about the best approach — timelines, batching, and everything in between.
Yes. We can generate simple inspection reports, PPAP reports, and Cpk studies. Our quality management software allows us to accurately document the level of reporting your job requires.
