Customer Reviews
Components are pretty good. Fair price.

—— Jackshee Best- USA

Our customer has tested the machined part, now it works well, thank you.

—— Dereck Lammers- Mexico

I used your parts for a assembly project to cut some holes in some 1/8 thin gauge steel. It did start easily into the steel and seemed to cut it with not a lot of pressure.

—— Brady Walter- Canada

I recommend Toxmann products to my friends. Good quality, good service.

—— Connor Smith- USA

The grinding parts make it better for our products to bite. Toxmann makes the best mold parts!

—— Stefan Geitner- Germany

These precision parts are a great addition to our construction company, good quality makes us work more easier.

Q1: Can knurling be done by hand?
A: Knurling can be done either by machine or hand. Hand knurling uses a rolling roll that creates the desired pattern on the workpiece.

Q2: What is mechanical knurling?
A: Knurling is a mechanical process of rolling patterns on the knobs of metal products or other working surfaces, mainly for anti-skid purposes. And used in many hardware, mold, and mechanical components.

Q3: How is knurling measured?
A: For diagonal knurl wheels, the *TPI is measured perpendicular to the teeth or helix angle. The circular pitch measurement in inches, is derived from 1 inch divided by the number of Teeth per Inch with the exception of 14, 21, and 33 TPI.

Q4: Is knurling a turning operation?
A: The variation of tool ends and a kinematic relation between the tool and workpiece results in different operations on a lathe. The most common lathe operations are turning, facing, grooving, parting, threading, drilling, boring, knurling, and tapping.

Q5: What is knurl size?
A: Knurls can be supplied in various types, in either circular or diametral pitch, to suit individual requirements. The four diametral pitches available are 64, 96, 128 and 160. A large variety of knurl blanks are regularly carried in stock, insuring fast delivery on special knurls made to customer's specifications.

Q6: How deep should a knurl be?
A: How “deep” to knurl? A fine knurl is 0.010-0.015 inch, a medium knurl 0.015-0.025, and a coarse knurl 0.025-0.035.

Q7: Can you knurl aluminum?
A: Knurled finishes on aluminum are one of our most popular metal finishes. Knurling is a visually attractive diamond shaped pattern cut or rolled into metal. This pattern allows you to get a better grip on the knurled object than would be provided by the original smooth metal surface.

Q8: What is straight knurling?
A: Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled or crossed lines is rolled into the material.
