Value Collection 00382358 M4x0.7 Combination Drill Tap Hss

Product Description

The VALUE COLLECTION 00382358 is a combination drill tap designed to drill and tap an M4x0.7 metric coarse thread in a single operation. Made from high-speed steel, this tool handles both cutting operations without requiring a separate drill bit and tap. The drill diameter measures 0.1299 inches (3.30 mm), the thread length is 0.5 inches, and the overall length is 2.125 inches. It carries a thread limit of D4, indicating a standard tolerance class for metric taps. Machinists, maintenance technicians, and fabricators use this type of tool to reduce setup time and improve hole-to-thread concentricity in production and repair work.

This combination drill tap is suited for use in ferrous and non-ferrous metals where M4x0.7 metric coarse threads are required. Typical applications include machine assembly, panel fabrication, and equipment repair in industrial, HVAC, and electrical trade environments. The single-pass design is particularly useful when working in constrained spaces or when drilling and tapping must be performed in line with a drill press or CNC setup. Thread limit D4 makes it appropriate for standard-fit thread applications in through-hole and blind-hole configurations.

Key Features

• Drills and taps M4x0.7 metric coarse threads in a single pass
• High-speed steel construction for durability in metal cutting applications
• Drill diameter of 0.1299 inches (3.30 mm) matched to M4x0.7 thread geometry
• Thread limit D4 for standard metric thread tolerance
• Compact overall length of 2.125 inches suits tight-access applications
• Thread length of 0.5 inches provides adequate engagement for typical fastener depths

Compatibility

Designed as an OEM-style replacement or direct-use combination drill tap for applications requiring M4x0.7 metric coarse threads in standard D4 thread limit tolerance class.

Installation Notes

A licensed machinist or skilled technician should install this tool in a drill press, CNC machine, or appropriate hand-held driver rated for tapping operations. Ensure the workpiece is securely clamped before beginning the cut. Use a suitable cutting fluid for the base material to extend tool life and improve thread finish. Do not exceed the tool's recommended speed range for the material being tapped, and back off periodically to clear chips when working in blind holes.
