Diamond Special-Shaped Professional Files 100# Grit

These 100# grit diamond files are engineered for precision work in tight, hard-to-reach areas where standard files simply cannot fit.

At 215mm in length with specially profiled working surfaces, they reach into mold cavities, clean up seam lines, smooth internal arcs, and refine recessed corners with consistent, controlled cutting action.

Available as a 5-piece set or as individual profiles to complete a specific gap in your toolkit.

Diamond-Coated Steel Construction

Each file is made from solid steel with an electroplated diamond abrasive surface. Diamond abrasive cuts faster and lasts significantly longer than conventional abrasives, remaining effective on hardened steel, tool steel, and other demanding materials without glazing or loading up.

Five Specialized Profiles

The five models cover the most common problem geometries in mold and part finishing: flat seams, rounded arcs, narrow grooves, angled chamfers, and blended transitions. Each profile is optimized for a specific surface type, reducing the need to improvise with an ill-fitting tool.

Specifications

• Grit: 100# (medium-fine).
• Length: 215mm (approx. 8.5 in).
• Material: steel shank with diamond abrasive coating. 

Ideal For

Mold makers, toolroom technicians, scale modelers cleaning up resin or metal cast parts, and hobbyists who need fine, controlled material removal in confined spaces.
