M10 – Tungsten Carbide Friction Flow Drill Bit

The hot melt drill is a tapered tool made of special tungsten carbide. It uses high speed rotation and high axial pressure to generate a large amount of frictional heat on a thin tube or plate, where the material at the point of processing is in a “super plastic” state and the tool displaces and shapes this part of the material to form a bushing. The height of the bushing can be 3-4 times the thickness of the original workpiece.

Hot melt drill is widely used in automobiles, motorcycles, construction, decoration, machine tools, machinery, aerospace electronics, electrical appliances, furniture, waterways, shipbuilding and automation equipment and other aspects.

Classification of hot melt drill:

This is a flat hot melt tool and will create the internal wall and then cut the excess material away to leave a smooth face

Used for commonly use thin-walled parts. Suitable for penetrating workpiece thicknesses of 0.8mm-3mm. The cylindrical part of the drill is short, and the hole after extrusion into a conical shape can make the tapping strength stronger.

Please note that this tool is a consumable, as would be the tapping tool that you would need to tap the hole once the hole has been made.

While this tool is capable of producing 1000s of flow drilled holes, it does need to be operated in the correct environment.

For M10 Carbide Flow Drill Bit:
– The tool produces a 9.2mm hole ideal for a 1.5mm pitch thread
– Drilling Speed: 2000 RPM
– Drilling machine: 1.5kw pedestal drill press or bigger
– Feed Rate: 150mm/min
– Drill Time: 2 seconds
– Tapping machine speed: 400RPM

Please always use a rolling tap when creating threads as a cutting tap will remove the wall and reduce the strength of the thread created
