Precision Twist Drill 1010070 Plug Tap 7/16-14

Product Description

The PRECISION TWIST DRILL 1010070 is a 1500 Series hand plug tap designed for cutting 7/16-14 UNC (Unified National Coarse) threads in a wide variety of materials. At 3-5/32 inches in overall length, this tap is sized for standard hand-tapping operations in both through-hole and blind-hole applications. Plug taps feature a chamfer of approximately 3 to 5 threads, making them the most common starting point for threading operations where the hole is already started or where a taper tap has been used first. Machinists, maintenance technicians, and general trade professionals reach for this style of tap across metalworking, HVAC, plumbing, and mechanical maintenance tasks.

This tap is suited for threading operations in ferrous and non-ferrous metals, plastics, and other machinable materials. The 7/16-14 thread specification is a coarse-thread standard commonly found on structural fasteners, machine bolts, and equipment frames across residential and commercial service work. It is sold in single-unit packs and is appropriate for shop use, field repair, and general maintenance applications where a reliable hand tap is needed.

Key Features

• Plug tap geometry with mid-range chamfer for use in through holes or blind holes after pre-tapping
• 7/16-14 UNC coarse thread specification for wide fastener compatibility
• 3-5/32 inch overall length suited to standard tap wrench tooling
• 1500 Series construction for broad material compatibility including metals and plastics
• Single-unit pack with no minimum quantity beyond one

Compatibility

Designed as a standard hand plug tap for use in any through-hole or blind-hole tapping application requiring 7/16-14 UNC coarse threads. Works with standard tap wrenches and tapping handles that accept straight-shank taps of this size.

Installation Notes

This tap is installed by hand using a tap wrench; secure the workpiece firmly before beginning. Always use the appropriate cutting fluid or tapping compound for the material being threaded to reduce friction and extend tap life. Back the tap off periodically during cutting to break chips and prevent binding, particularly in blind-hole applications. Inspect the tap for wear or damage before each use, as a cracked or dull tap can seize or break in the hole.
