Diamond Coated Needle Files (28 Products)

Diamond coated needle files feature small particles of industrial diamond embedded in their surface instead of traditional cut teeth. Tool and die makers use them to shape extremely hard materials such as hardened steel, carbide, glass, and stone where standard steel files are ineffective.

Available Diamond Coated Needle File Types

• Yato flat diamond coated needle files
• JK square and hand diamond coated needle files
• JK three square and knife diamond coated needle files
• Choice of 140 mm and 160 mm lengths in '0' and '2' cuts

How to Choose the Right Diamond Needle Files

Select your diamond needle file based on the hardness of the workpiece and the specific profile required. Industrial diamond grit allows for smooth cutting on brittle or hardened substrates without edge chipping. Match the length and shape, such as flat or knife, to the contours of your application.
