Precision Twist Drill 1012370 Plug Tap Spiral Flute

Product Description

The PRECISION TWIST DRILL 1012370 is a plug tap from the 1534 series, designed for general-purpose machine tapping in a wide range of materials. This tap features a spiral flute geometry with a relieved-style spiral point and eccentric relieved threads with full pitch diameter relief. The result is a freer cutting action that reduces torque during operation and significantly extends tool life compared to standard plug taps. At 2.125 inches in length and weighing 0.15 pounds, it is sized for use in standard tapping fixtures and machine tool setups. Licensed machinists and tool-and-die tradespeople commonly specify this type of tap for production threading work.

This plug tap is suited for general-purpose threading applications across industrial, maintenance, and production environments. The spiral flute design helps evacuate chips away from the cutting zone, making it particularly effective in blind-hole and through-hole tapping operations. It is intended for use in machine tapping setups where consistent thread quality and extended tool life are priorities. Typical applications include threading operations in steel, cast iron, aluminum, and similar machinable materials.

Key Features

• Spiral flute, relieved-style spiral point for freer cutting and reduced torque
• Eccentric relieved threads with full pitch diameter relief for longer tool life
• Plug tap chamfer style suitable for both through-hole and blind-hole applications
• 1534 series general-purpose design for broad material compatibility
• Compact 2.125-inch length fits standard machine tapping setups

Compatibility

Designed as an OEM-style replacement or direct-use general-purpose plug tap compatible with standard machine tapping holders and fixtures sized for this tap series.

Installation Notes

This tap should be installed and operated by qualified machinists or tool-and-die technicians familiar with machine tapping procedures. Ensure the workpiece is securely fixtured and the tapping machine is set to the appropriate speed and feed for the material being threaded. Use the correct cutting fluid for the workpiece material to maintain thread quality and tool life. Inspect the tap for wear or damage before each use and replace if thread form quality degrades.
