Dormer E501 HSS Metric Coarse LEFT Hand Tap M4 Plug

This Dormer E501 HSS Metric Coarse Left-Hand Tap is the definitive solution for creating left-hand threads in M4 applications, offering professional engineers and machinists the precision and durability needed for reverse-thread fastening. Meticulously crafted from high-speed steel, it delivers exceptional wear resistance and consistent cutting performance, making it ideal for maintenance, repair, and production tasks where standard right-hand taps cannot meet the requirement. The left-hand fluting ensures chips are cleared efficiently during operation, reducing the risk of tap breakage and producing clean, accurate threads every time.

- Manufactured from premium high-speed steel (HSS) for superior hardness and long tool life

- Designed specifically for metric coarse (M4 x 0.7) left-hand threading in ferrous and non-ferrous materials

- Plug tap configuration allows for general-purpose through-hole and blind-hole threading

- Left-hand spiral flutes promote effective chip evacuation and reduce cutting torque

- Precision-ground cutting edges provide sharp, consistent thread profiles with minimal burr formation

- Conforms to Dormer’s exacting quality standards for professional-grade reliability

Perfect for applications in automotive, engineering, and bespoke fabrication where left-handed fasteners are specified, this tap is a trustworthy addition to any serious tool kit.
