20 mm Forming Drills: Precision Built for Production Efficiency

31 Mar 202620 mm · Forming drill · Solid carbide · Custom tooling · Production
Custom 20 mm forming solid carbide drill for controlled enlargement and forming hole geometry

Forming drills are designed for more than “drilling”: they enlarge and shape the hole so the geometry matches the print with higher repeatability. For a 20 mm forming drill, the manufacturing challenge is balancing cutting load with stable guidance so the tool keeps the forming shape consistent over production time.

Technical Specifications
FeatureSpecification
Tool typeThree-point / centering-forming profile
Diameter20 mm (customizable to your drawing)
MaterialSolid carbide (tungsten carbide)
CoolantSolid or internal coolant-through versions
Target tolerancesAligned to m7 / h6 / h8 class requirements
ApplicationAlloy steel, stainless, cast iron, aluminum, and production work-holding systems
Controlled forming profile
Stable hole enlargement with consistent step/flat geometry to reduce secondary operations.
High-strength guidance
Precision centering and robust cutting-edge support for repeatable positioning under load.
Production-ready chip evacuation
Helix/flute form and coolant options designed to keep chips moving in the forming zone.
Long tool life focus
Carbide substrate and coating selection tailored to your material and cutting parameters.

Why the 20 mm scale matters: as diameter grows, even small deviations in guidance and cutting-edge geometry are magnified into hole errors and faster wear. This forming drill case highlights our approach—tight grinding control, profile verification, and inspection criteria aligned to your production acceptance.

If your print requires controlled hole forming at 20 mm (or a step/flat feature near the entrance/shoulder), send the drawing, material + hardness, required tolerance class, depth, and available coolant pressure. We will propose the right solid or coolant-through forming drill configuration for your programme.
