V-COIL notch Inserting Tool M 6 x 1.0, 1/4 inch hex drive

The M6 wire thread insert installation tool from VÖLKEL, item 09109, sets V-COIL notch inserts into M 6 x 1.0 threads. The body is a threaded mandrel carrying a drive shank. The shank ends in a 1/4 inch hex connector. That connector fits a ratchet, a hand wrench or a power screwdriver. Tool length is 70 mm. It is built to Works Standard and supplied as one piece.

Notch-type inserts are wound onto the mandrel thread before installation. The mandrel then guides the insert into the prepared and tapped hole. Because the drive is a common 1/4 inch hex, the same tool suits bench work and on-site repairs. Thread system is metric, with the single designation M 6 X 1.0. The tool is size-specific, so it covers only M 6 x 1.0 applications.

M6 wire thread insert installation tool for V-COIL notch inserts

V-COIL notch inserts restore worn or stripped threads in softer base materials. The installation mandrel controls the insert during winding, which keeps the coil aligned with the tapped hole. This model handles a single metric size. Machinists therefore keep one mandrel per thread designation in the workshop. The 70 mm length gives enough shank clearance for most hand and powered drives.

Construction and drive

The working end is a threaded mandrel matched to the insert pitch. Behind it sits a plain shank that terminates in the 1/4 inch hex drive. No separate adapter is needed for standard bit holders or hex sockets. The manufacturer lists the tool under its own works standard rather than a public DIN or ISO number. Packing is one piece per item.

• Tool type: V-COIL notch inserting tool
• Thread system: metric (M)
• Thread designation: M 6 X 1.0
• Drive connector: 1/4 inch hex
• Total length: 70 mm
• Standard: Works Standard

Use the mandrel with a ratchet or a power screwdriver, depending on access. The hex connector transfers torque directly to the insert coil. Keep the tool aligned with the hole axis while winding. After installation the mandrel is withdrawn from the finished thread. Store the tool by size so the correct mandrel is picked for each repair job.

Common applications

Thread repair work in aluminium, magnesium and cast housings is the main field. The tool also serves new assemblies where an M 6 x 1.0 thread must carry higher load in a soft parent material. Typical users include engine and gearbox repair shops, machine building, tool rooms and maintenance teams. It also fits mould and jig work where tapped holes see frequent bolt changes. Any job calling for an M 6 x 1.0 V-COIL notch insert can use this mandrel.

Catalog technical content

The manufacturer data sheet lists the item as a V-COIL notch inserting tool with thread system M and thread designation M 6 X 1.0. Size is stated as M 6 x 1.0, the drive connector as 1/4 inch, and the length as 70 mm. The standard field reads Works Standard. The application field repeats M 6 x 1.0. Packing is one piece per order unit.

Selection is straightforward. Match the mandrel size to the wire thread insert size and to the tapped hole. For other metric threads, a separate inserting tool of the matching designation is required.
