Value Collection -22442-10 Hand Sti Tap M10 X 1.5

Product Description

The VALUE COLLECTION -22442-10 is a hand STI tap designed for cutting M10 x 1.5 Metric Coarse threads in through-holes and blind holes. STI taps are used specifically to cut oversized threads that accept Heli-Coil style thread inserts, restoring damaged threads or reinforcing threads in softer base materials. This tap features a D3 thread limit, 4 flutes, and a plug chamfer with 3 to 5 leading threads for general-purpose tapping. Constructed from high speed steel with a bright finish, it handles a wide range of metals and alloys under typical shop conditions. Overall length is 3-3/8 inches. Machinists and maintenance technicians reach for this tool in thread repair and fabrication applications.

This tap is suited for hand tapping operations in job shops, maintenance and repair facilities, and manufacturing environments where M10 x 1.5 STI thread inserts are being installed. The plug chamfer makes it appropriate for both through-hole and sufficiently deep blind-hole applications. It is well-matched to steel, cast iron, aluminum, and similar workpiece materials at standard cutting speeds for high speed steel tooling.

Key Features

• M10 x 1.5 Metric Coarse thread form for STI insert preparation
• D3 thread limit for controlled fit with thread inserts
• 4-flute geometry for balanced chip load and clean thread form
• Plug chamfer with gradual lead-in for general hand tapping
• High speed steel construction for durability across a range of metals
• Bright finish, 3-3/8 inches overall length

Compatibility

Designed for use with M10 x 1.5 Metric Coarse STI thread inserts, including Heli-Coil style wire inserts used in thread repair and thread reinforcement applications.

Installation Notes

This tap is intended for hand tapping operations performed by machinists or maintenance technicians. Before tapping, ensure the workpiece is securely clamped and the pilot hole is drilled to the correct STI tap drill size for M10 x 1.5 inserts. Use appropriate cutting fluid for the workpiece material to extend tool life and produce a clean thread. Back off periodically to break chips, and never force the tap against resistance.
