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.
Flat-Mouth Flush Seating: Produces a clean, flat counterbored rim ideal for flush fastener seating without raised collars.

Executive Overview
The Precision DM M10 Ø9.2mm Long Flat Thermal Friction Drill Bit by DUOMI CNC offers advanced thermal friction drilling (flow drilling) technology designed for high-volume B2B manufacturing. Constructed from ultra-durable solid tungsten carbide, this tooling system generates frictional heat up to 600°C–800°C to locally plasticize thin-walled metals.
Unlike traditional chip-cutting drills, the M10 long flat profile displaces material downwards to form a continuous, high-strength bushing—extending thread length up to 3x the original sheet thickness. The flat (planed-mouth) cutting geometry simultaneously trims the surface collar, producing a perfectly flush finish in a single high-speed pass.
Key Technical Specifications & Advantages
- Chipless Bushing Generation: Eliminates metal swarf, scrap waste, and post-drilling cleaning operations.
- Planed Flat Surface Finishing: Integrated face cutters remove the top collar during the penetration cycle for a smooth surface ideal for flush gasket seating or aesthetic joints.
- High Tensile & Torsional Strength: Bushings support full thread engagement (M10 x 1.5 pitch) with pull-out forces exceeding conventional rivet nuts by up to 300%.
- Tungsten Carbide Construction: Engineered for extreme heat dissipation and thermal shock resistance, delivering 3,000–5,000 hole production life spans under optimal cooling conditions.
- Universal CNC & Drill Press Compatibility: Fits standard CNC machining centers, high-speed drill presses, and dedicated tapping units.
Operational & Economic ROI
By replacing traditional weld nuts, press inserts, and blind rivet fasteners, the DUOMI M10 flat thermal friction drill bit reduces cycle times by up to 75% and lowers hardware assembly costs significantly:
- Cycle Time Reduction: Complete hole formation and collar facing in 2 to 4 seconds.
- Material Savings: Eliminates secondary fast-locking hardware purchases and manual insert labor.
- Process Reliability: 0% risk of loose thread inserts during structural vibration or high thermal shock.
Primary Industrial Applications
- Automotive & Transportation: Lightweight chassis framing, seat structures, and exhaust manifolds.
- HVAC & Fluid Heat Exchangers: Thin-walled manifolds, liquid-cooling tubes, and solar thermal collectors.
- Metal Fabrication & Furniture: Stainless steel architectural handrails, modular office furniture, and frame joinery.
- Structural Engineering: Hollow structural section (HSS) connections and bearing housings.
Operating Guidelines & Parameters
- Recommended Spindle Speed: 1,800 – 2,600 RPM (depending on base material hardness).
- Target Material Thickness: 2.0 mm – 4.5 mm sheet metal or tubing.
- Compatible Base Metals: Mild steel, stainless steel (304/316), aluminum alloys, brass, copper, and high-strength alloys (Inconel, Hastelloy).
