BB Thermal Friction Hot Melt Short Drill Bit Solid Carbide Hole Making Tool M3 M4 M5 M6 M8 M10

BB Thermal Friction Drill

The parameters in the above table are for low-carbon steel with a thickness of 2mm;
For thicker materials, each additional 1mm increases the processing time by 1 second;
When drilling stainless steel, if the thread diameter is M6 or larger, increase the hot melt drill diameter by 0.1mm and reduce the drill speed by 15%;
When drilling aluminum or other nonferrous metals, increase the drill speed by 50%.
*It is recommended that the workpiece thickness should not exceed 2.5mm.

Hot Melt Drilling Process Saves Time, Labor, and Cost

No Drilling Required
Conventional Welding Nut
Friction Drill Process Thread
Threaded bushings can be formed on the surface of thin materials in just a few seconds, requiring no additional materials. Only two steps are needed to produce high-precision products.
This effectively solves the problem of tapping threads in thin sheets, square tubes, and round tubes, greatly increasing connection strength. It eliminates the need for spot welding of cylinders, nuts, and washers, reducing processing steps, and offers high precision, thereby reducing product scrap rate and saving production costs.

Friction Drill Process Provides Very Hard Threads On The Surface Of Thin Materials
Very Effective In Replacing The Process Of Threaded Nuts And Rivet Nuts

Friction Drill Working Principle

Friction Drill Drilling and Tapping Process
The Friction drilling process generates heat through high-speed rotation and axial pressure friction, causing material plasticization and displacement. It simultaneously drills holes and forms a bushing approximately three times thicker than the original material. Through the extrusion tapping process, it creates high-precision, high-strength threads on thin materials.
Step 1：Through high-speed rotation and axial pressure, the material is plasticized and displaced to form a bushing whose thickness is three times that of the original material
Step 2：The thread is formed by the cold extrusion method, creating high-precision, high-torque, and high-specification threads.

Friction Drill Multiple Choices

Rounded End-Rounded End Effect
Flat End-Flat End Effect
Based on the surface requirements of the workpiece after Friction Drill penetration, there are two types of hot melt drills:
Rounded End (Standard Type): The Friction Drill penetrates the workpiece, forming a bushing while simultaneously creating a raised ring on the surface of the workpiece.
Flat End (Flush Type): The Friction Drill penetrates the workpiece, forming a bushing while simultaneously trimming off the raised ring, resulting in a smooth surface on the workpiece.

Friction Drill Auxiliary Tools

When used together, it makes your work easier.

01：Tool Holder：Using a standard tool holder will reduce the service life of the drill and the spring collet. Using a dedicated tool holder is more beneficial to extend the service life of the hot melt drill bit.
02：Tap：After drilling with a thermal drill, tapping can be done with a thermal tap, which can machine cold-formed threads.
Why choose extrusion taps:
The holes made by hot drilling are thinner due to the stretching of the hole wall. Using traditional cutting taps would damage the hole wall and reduce its strength. Therefore, it is recommended to use extrusion taps with hot drilling.
03:Friction Adhesive：When used with the hot melt adhesive, drilling becomes easier, reducing drill bit wear and effectively protecting the bit.
