SPG Type Milling Drill, 3×38mm Conical Cutter with 3×13mm Shank

Brief Overview

This SPG-type milling drill delivers precision performance for detailed machining operations where surface finish and controlled material removal take priority. The compact 3mm shank with extended 38mm conical cutting head reaches into tight access points and intricate details that standard burrs cannot address. The cross-cut diamond flute geometry minimizes chatter and produces predictable results on hardened steel and non-ferrous materials alike. For broader applications, consider pairing this with larger conical cutters for general machining work or exploring alternative deburring profiles for specialized corner finishing.

Key Features

• Cross-cut diamond flute geometry – Intersecting spiral cuts provide efficient chip evacuation and reduce surface drag during operation
• Tapered conical cutting head – Delivers precise, controlled material removal with minimal vibration and chatter
• Smooth cylindrical shank – 3mm diameter designed for secure chucking in standard collets and universal rotary tool holders
• Bright metal finish – Uncoated high-speed steel construction offers excellent hardness and heat resistance
• Compact overall dimensions – 51mm total length ideal for detailed work where access and precision take priority over cutting volume

Business Advantages for Resellers

Universal Compatibility: The 3mm shank fits standard rotary tool and precision spindle systems across multiple manufacturers—a universal size point that broadens your customer base without inventory fragmentation.

Consistent Demand Across Sectors: Tool component machining, die work, jewelry fabrication, and detailed prototype development create steady demand across multiple trade sectors, reducing inventory risk.

Professional Packaging: Arrives in clear protective storage tube with printed specification label and blue protective caps—minimal repackaging effort required, professional appearance preserved for retail presentation.

Margin Stability: Precision cutters maintain healthy margins due to specialized applications and stable demand among professional users who prioritize surface finish and reliability over cost competition.

Why This Tool Matters to Your Customers

Machinists and tool-makers rely on cross-cut conical geometry to achieve the smooth surface finish that separates professional work from basic machining. The 3×38mm profile excels in deburring, corner finishing, and engraving tasks where standard large burrs create stress or lack precision control.

Unlike general-purpose cutters, this SPG design produces predictable, high-quality results on hardened steel and non-ferrous materials. The compact head reaches confined access points and intricate details where larger tools simply cannot operate—making it irreplaceable for specific job requirements.

Stock this as a precision essentials item. Specialized geometry + universal 3mm shank compatibility + consistent professional demand = reliable inventory that builds long-term customer loyalty and repeat orders.
