Thread Tapping Drill Bit Set Silver 7-piece M3–M10 model 11535

Silver 7-piece thread tapping drill bit set model 11535 contains taps for metric internal threads from M3 to M10. The set is designed to create and repair internal threads in metal and other machinable materials, covering the commonly used sizes M3, M4, M5, M6, M7, M8 and M10. Components are arranged to support workshop and maintenance operations where precise thread cutting is required.

Advantages

The set offers a compact selection of metric taps that reduces the need to source individual sizes. Taps are suitable for a range of machinable materials, allowing one kit to serve multiple applications. The consistent geometry across sizes supports uniform thread quality and simplifies tool selection for standard metric fasteners.

Suitable for

• Creating new internal threads in metal components
• Repairing damaged or worn internal threads
• Workshop maintenance and mechanical assembly tasks
• Preparing threaded holes for standard metric bolts and screws

Key specifications

• Number of pieces: 7
• Thread sizes included: M3, M4, M5, M6, M7, M8, M10
• Intended thread type: Metric internal threads
• Material applications: Metal and other machinable materials

How to use

Select the appropriate tap size for the intended bolt or screw and center it in the pre-drilled hole of the correct drill diameter. Secure the workpiece to prevent movement. Apply cutting fluid if machining metal, insert the tap into a suitable tap wrench or holder, and turn clockwise to engage the thread, using incremental forward and partial reverse motions to break chips and clear debris. After cutting to the required depth, reverse the tap fully to remove it, clean the threads and inspect for correct fit.

Usage recommendations

Use the correct drill size for each thread to ensure proper thread engagement. Apply appropriate cutting fluid for metallic materials, clamp the workpiece securely, and avoid excessive force to prevent tap breakage. For precision threads, check fit with the mating fastener and deburr edges after tapping.
