Hot melt drill bit

Product positioning: Made of hard alloy material, the hole and liner are formed by high-temperature friction extrusion in one go, replacing the traditional drilling+welding/riveting nut process.

Product Overview:

Ruiyi RUIYI Hot Melt Drill is a conical tool made of special wear-resistant and high-temperature resistant hard alloy. By high-speed rotation and intense friction with the metal surface, high temperatures are generated, causing the material at the machining point to be in a plastic state, flowing along the hole wall under axial thrust, and extruding the liner on the lower surface of the workpiece. The entire process is formed in one go, without the need for secondary processing. This process completely replaces the traditional way of welding or riveting nuts on thin-walled workpieces, and is particularly suitable for industrial automation production. Huayi Tools is located in Zhuzhou, the capital of hard alloys. Its independent brand Ruiyi RUIYI hot melt drill has been widely used in multiple industries and has been validated by the market.

Usage scenarios:

Thin walled pipe connections for automotive parts, rail transportation, agricultural machinery, etc.

Threaded connections for metal furniture, shelves, guardrails, and other frame structures

Air conditioning pipes, pressure vessels, heat exchange system tube plate connections

Suitable for manual bench drills, ordinary drilling machines, milling machines, and CNC machining centers

Product advantages:

Chip free machining, clean and efficient - the machining process produces no chips, avoiding chip damage to the machine parts. The hole wall is smooth and free of burrs, eliminating the need for chip removal treatment.

High strength Connection · Alternative Welding - The extruded lining metal fiber is continuous and does not break, and the thread strength is higher than traditional cutting threads, which can completely replace welding nuts.

Dual specification flexible adaptation - the round mouth type retains the convex ring on the surface of the workpiece (can be used as a nut washer), and the flat mouth type removes the convex ring (the surface of the workpiece is smooth), meeting different appearance and assembly requirements.
