The PRECISION TWIST DRILL 1012517 is a metric plug tap from the 1700M series, designed for cutting internal threads in a wide variety of materials. It features a straight flute geometry suited for general-purpose hand tapping operations. Plug taps start the thread after a taper tap has begun the cut, making them the most commonly used tap style in standard threading sequences. Weighing 0.15 pounds, this tap is a lightweight, single-piece tool sold individually and used by machinists, maintenance technicians, and trade professionals working with metric fastener standards.
This tap is appropriate for use in through-hole and blind-hole applications across a range of workpiece materials. The straight flute design works well in most common metals and materials encountered in general shop and field maintenance work. The 1700M series designation indicates this is a metric-specification tap, making it suitable for threading holes to accept metric fasteners in both production and repair contexts.
Designed as a general-purpose metric hand tap suitable for threading operations in through-hole and blind-hole configurations across a wide range of materials.
This tap is installed by hand using a tap wrench or appropriate holder — power tapping without the correct setup can result in tap breakage. Always ensure the hole is drilled to the correct metric tap drill size before threading. Apply cutting fluid appropriate to the workpiece material to extend tap life and improve thread quality. Back the tap out periodically to clear chips, especially in blind-hole applications.
