Product Description

3-Inch Tapered Diamond File Description & Features

This industrial-grade 3-inch tapered diamond file is engineered for precision sharpening and finishing across a wide range of tools and materials. Designed with a flat and convex back, it is ideal for sharpening woodturning gouges (internal and external bevels), skews, carving tools, chisels, router bits, saw blades, knives—including serrated edges—as well as pruners, shears, and other shaped tooling.

Constructed with a premium 400-grit microcrystalline diamond mesh electroplated onto a lightweight oval steel shaft, this file delivers fast, efficient cutting action and a refined edge without the mess of traditional oil or water stones. Suitable for both carbide and high-speed steel (HSS), it ensures high performance and long service life in demanding applications.


Key Features

  • Precision Tapered Design – Flat and convex back profile provides superior control for sharpening curved, serrated, and hard-to-reach edges.

  • Premium Diamond Coating – 400-grit microcrystalline diamond mesh nickel-bonded for durability, consistent abrasion, and extended tool life.

  • Wide Tool Compatibility – Efficiently sharpens gouges, skews, carving tools, router bits, saw blades, chisels, knives, serrated edges, pruners, shears, and more.

  • Industrial-Grade Versatility – Effective on carbide, HSS, hardened steels, plastics, and non-ferrous metals.

  • Efficient Sharpening – Delivers a razor-sharp edge without requiring oil or water; for best results, apply minimal Trend lapping fluid.

  • Durable & Lightweight – Oval steel shaft ensures strength with easy handling for precision work.

Application

Tapered Diamond File — Applications


Overview

The tapered diamond file is a precision finishing tool engineered for access to tight radii, slots, serrations and internal bevels. Its tapered profile and nickel-bonded microcrystalline diamond coating make it ideal for rapid, repeatable stock removal and high-quality edge formation on hard and composite materials.


Primary applications

  • Woodturning & Woodworking — Internal and external bevels of gouges, skews, small chisels, carving tools and sculpting tools.

  • Cutting tools & blades — Sharpening knives (including serrated edges), saw blades (teeth filing), router bits, planer blades and hobby knives.

  • Metalworking & Engineering — Deburring and finishing on HSS, tool steel, tungsten carbide tips, small machined parts, model engineering components and dies.

  • Garden & Outdoor Tools — Pruners, shears, loppers and timber-framing tools that require precise edge geometry.

  • Plastics & Composites — Trimming and finishing of engineered plastics, FRP, and non-ferrous components where controlled material removal is needed.

  • Jewellery & Fine Work — Filing fine contours, inside curves and delicate profiles on precious metals and hard inlays.


Material compatibility

  • Carbide (tipped tools), tungsten, HSS, hardened steels

  • Non-ferrous metals (brass, bronze, aluminium)

  • Ceramics, glass and engineered composites

  • Plastics and laminates


Typical use cases & benefits

  • Restoring lost bevels and reconditioning worn cutting edges without removing tool geometry.

  • Accessing internal bevels and curved profiles that flat files cannot reach.

  • Fast, controlled sharpening with minimal heat and no soaking/oiling required.

  • Producing a consistent, high-grade cutting edge suitable for professional and industrial use.


Recommended technique

  • Use light, even pressure and long, even strokes along the bevel.

  • Match the file’s taper/profile to the tool geometry for best contact.

  • For very hard materials or to speed cutting, a drop of lapping/trend fluid may be used; excessive lubricant reduces cutting efficiency.

  • Keep a consistent sharpening angle; check periodically with a marker or angle guide.

  • Clean diamond surface with a nylon brush or scouring pad to remove embedded particles.


Maintenance & lifetime tips

  • Do not apply excessive lateral force — work with the file’s geometry.

  • Store dry and protected from impact or bending.

  • Periodically remove clogging debris with a brass/nylon brush and light solvent if needed.

  • Replace when diamond coating shows uneven wear or when material removal performance significantly declines.


Industries that benefit

Toolmaking, woodworking shops, furniture manufacturing, gardening/landscape tool manufacturers, metal fabrication, aerospace and electronics (precision deburring), jewelry workshops, and maintenance/repair operations (MRO).
