Description

WRC Type Milling Drill, 3mm Cutting Head × 38mm Length – Precision Deburring & Corner Finishing

Overview

This WRC-type milling drill is purpose-built for precision deburring and internal corner finishing in tool production, die work, and precision machining environments. The 3mm cutting head with helical cross-cut fluting delivers smooth, burr-free surfaces on workpieces, while the compact 38mm overall length provides optimal accessibility in tight work areas. The rounded cutting end prevents workpiece damage and ensures controlled material removal—critical when finishing internal corners and confined spaces where larger tools cannot reach. For shops requiring a complete deburring toolkit, consider pairing this with larger-diameter milling drills to scale production runs or explore alternative cutting geometries for specialized finishing requirements.

Key Features

  • 3mm cutting head with helical cross-cut fluting for smooth, controlled finishing passes
  • 38mm overall length engineered for accessibility in tight corners and confined areas
  • Straight cylindrical shank (3mm diameter) ensures precise clamping and minimal runout
  • Rounded cutting end reduces workpiece damage and prevents sharp edge marking
  • High-speed steel construction delivers durability and effective heat dissipation during continuous operation

Real-World Applications

This tool excels in precision environments where size and surface finish are non-negotiable:

  • Internal corner deburring – Specifically designed for 90-degree inside corners and groove finishing
  • Tool & die production – Essential for achieving the smooth surfaces required in precision tool manufacturing
  • Edge finishing transitions – Creates polished, controlled transitions on machined components
  • Confined space work – The compact 3mm head reaches areas where standard deburring tools cannot fit

Business Advantages for Resellers

  • High-demand specialty tool – Precision shops require multiple sizes and geometries for complete finishing workflows
  • Consumable replacement cycle – Regular wear on the cutting head drives consistent repeat orders
  • Margin-friendly product – Specialized geometry supports premium positioning with healthy distributor margins
  • Cross-sell momentum – Customers purchasing this compact size typically need complementary tooling for broader finishing requirements
