Features
Thermal Friction Flow Forming: Operates at 600°C+ to plasticize metal and extrude a strong threaded bushing in seconds.
Replaces Rivet & Weld Nuts: Creates a monolithic extruded boss with 3x the original sheet metal wall thickness.
Ultra-Hard Tungsten Carbide: Micro-grain solid carbide substrate provides extreme heat resistance and 10,000+ hole tool life.
Universal Thin-Wall Metal Forming: Optimally suited for carbon steel, stainless steel, aluminum tubing, and copper.

Overview
The DUOMI Professional DM M10 Ø9.2mm Thermal Drill Bit utilizes high-speed rotational friction to generate localized thermal energy, soft-forming metal wall materials to produce robust, high-strength bushings without producing chips. Engineered specifically for M10 thread forming taps, this Grade-A Tungsten Carbide tool forms an extruded collar that increases thread engagement length by 2x to 3x compared to standard sheet metal drilling.
Designed for hollow profiles, structural steel tubing, and thin-walled metal components, the DM M10 Ø9.2mm bit eliminates the need for weld nuts, rivet nuts, or threaded inserts, significantly lowering assembly time and operational costs.

Key Advantages of DM Thermal Flow Drilling
- Zero-Chip Clean Forming: Eliminates chip extraction and cleaning downtime, reducing post-processing labor by up to 80%.
- Superior Thread Load Capacity: Cold-formed M10 threads support higher torque and pull-out strength than traditional tapped holes in thin profiles.
- Precision Collar Options:
- Standard (Round): Creates a raised ring reinforcement ideal for extra load distribution.
- Flat-Cut (Planed): Simultaneously mills off the raised ring to deliver a smooth, flush surface finish.
- Extended Tool Life: Premium Grade-A Tungsten Carbide delivers up to 10,000+ hole cycles when operated with specialized thermal drilling paste.
How to Select the Right Thermal Drill Bit Version
- Standard Round Collar: Select when maximum thread length and structural collar reinforcement are required above the profile surface.
- Flat-Cut Collar: Choose when flat mating surfaces are needed for flush mounting, gasket seals, or aerodynamic assemblies.
Target Applications & Key Industries
- Automotive & Transportation: Chassis frames, seating brackets, exhaust supports.
- Building & Structural Metal Fabrication: Steel profiles, railing mounts, HVAC ducting, and heating manifolds.
- Fluid & Thermal Systems: Liquid cooling pipe manifolds, heat exchangers, and hydraulic tubing.
- Industrial & Commercial: Metal furniture frames, industrial lighting enclosures, and aerospace fixtures.
