Precision Twist Drill 6007103 Plug Tap 1/2-13 Hss

Product Description

The PRECISION TWIST DRILL 6007103 is a plug-style hand tap engineered for cutting internal threads in through-holes and blind holes in a wide range of workpiece materials. Part of the 1500 series, this tap features a straight-flute, 4-flute design ground to H3 tolerance for consistent thread accuracy. The plug chamfer style provides a 1.5-inch depth of cutting, making it suitable for general-purpose tapping operations where a starting chamfer and full thread engagement are both required. Weighing 0.108 pounds, the tap is sized for 1/2-13 coarse thread at a total length of 3.375 inches. Fabricated from cobalt steel with a bronze finish, it offers increased hardness and heat resistance compared to standard high-speed steel taps.

This tap is designed for general-purpose threading applications across metalworking, maintenance, and fabrication environments. The 1/2-13 coarse thread specification is one of the most common Unified National Coarse (UNC) thread sizes, making this tap a frequent choice for machine shops, maintenance technicians, and industrial trades working with fastener holes in steel, cast iron, aluminum, and similar materials. The straight-flute geometry works well in through-hole and shorter blind-hole applications where chips can be cleared from the cutting zone.

Key Features

• Plug chamfer style with 1.5 inches of cutting depth for general-purpose through-hole and blind-hole tapping
• 4-flute straight-flute geometry promotes chip clearance in a variety of workpiece materials
• H3 ground tolerance ensures consistent thread form and sizing accuracy
• Cobalt steel construction with bronze finish for elevated heat resistance and tool life
• 1/2-13 UNC coarse thread specification covers one of the most common fastener thread sizes
• Sold individually, one tap per package

Compatibility

Designed as an OEM-style replacement and general-purpose plug tap for standard 1/2-13 UNC straight-flute tapping applications in compatible tap handles and machine holders.

Installation Notes

This tap is installed by machinists and maintenance technicians using a standard tap wrench or machine tapping setup. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for a 1/2-13 thread before starting. Apply appropriate cutting fluid for the workpiece material to reduce heat buildup and extend tool life. Reverse the tap periodically during hand tapping to break and clear chips and prevent tap breakage in tougher materials.
