FORMDRILL

Short and long FORMDRILL friction drill bits refer to the overall length of the tool. Short bits are typically used when there is limited space or when the material thickness is relatively thin, as they provide a more compact setup. Long bits offer greater reach and are suitable for thicker materials or when additional clearance is needed. Both types are available in flat-finish configurations. The choice depends on the specific application, machine setup, and material thickness. For example, the FD0320SF is a short bit for #6-40 UNF threads, while the FD0570LF is a long bit for 1/4"-20 UNC threads.

FORMDRILL friction drill bits are designed for use on thin-walled materials, typically up to 5 mm thick, depending on the specific bit and thread size. Common materials include mild steel, stainless steel, aluminum, copper, and brass. The friction drilling process works by generating heat through friction, which softens the material and allows the tool to form a bushing without cutting. This makes it suitable for materials that are difficult to tap or where chip generation is a concern. However, the process may not be suitable for very hard or brittle materials. Always refer to the manufacturer's recommendations for specific material grades and thicknesses.

To select the correct FORMDRILL friction drill bit, first identify the thread type and size required, such as #6-40 UNF, 1/4"-20 UNC, M4 x 0.7, or 1/4" BSP. Then, determine the material thickness to ensure it does not exceed the maximum specified for the bit. FORMDRILL bits are designated by a part number that indicates the drill size and thread type. For instance, the FD0390LF is for #8-36 UNF threads with a 3.9 mm drill size and a maximum material thickness of 2.5 mm. The flat-finish design is indicated by the 'F' in the part number. Consult the product specifications for exact dimensions and thread compatibility.

FORMDRILL friction drilling offers several benefits over conventional drilling and tapping. It eliminates chip generation, which is advantageous in applications where swarf is problematic, such as in hydraulic or pneumatic systems. The process creates a bushing that increases the effective thread depth, often allowing the use of shorter screws. The work-hardened material around the hole can improve thread strength. Additionally, friction drilling combines drilling and tapping into a single operation, reducing cycle times and tool changes. It also avoids the need for separate chip removal and disposal. These factors can lead to cost savings and improved productivity in thin-material applications.

FORMDRILL collets and toolholders are designed to be compatible with standard machine spindles, such as those found on CNC machining centers, drill presses, and hand-held drilling tools. They are available in common shank sizes and configurations to fit various spindle interfaces. The collets are used to hold the friction drill bits securely and maintain concentricity. It is important to select the correct collet and toolholder for your specific machine spindle type and size. 3G Electric can provide assistance in matching the appropriate FORMDRILL toolholding components to your equipment. Always refer to the machine manual and FORMDRILL specifications for compatibility.
