WEICON High-Performance Tapping Oil, 400 ml

WEICON High-Performance Tapping Oil 400 ml is a technical spray cutting oil designed to lubricate the cutting zone in machining operations such as drilling and tapping, helping to reduce friction. Its mineral-oil-free formulation offers an advantage in processes aiming for cleaner machining. Its clear and almost odorless character makes it easier for the operator to visually follow the application area. Thanks to its silicone-free formulation, it supports maintenance and production processes without increasing the risk of silicone-related surface issues after machining. The manufacturer is WEICON GmbH & Co. KG (Germany).

Process benefit targeted with the Tapping Oil 400 ml technical spray
This technical spray aims for more stable cutting behavior through high lubricating effect in the cutting zone and helps limit heat build-up at the tool–surface contact. This approach supports more controlled tool performance, especially in operations such as tapping, drilling, and reaming. The product is positioned for use on steel, cast iron, stainless steel, copper, brass, aluminium, and alloys in operations such as turning, milling, sawing, and threading. In workshops and maintenance/repair units, it offers the advantage of fast application in pre-assembly hole preparation and tapping operations.

Performance characteristics derived from the technical/chemical structure
WEICON Tapping Oil is mineral-oil-free, silicone-free, and transparent. Since its kinematic viscosity is given as 43 mm²/s at 40 °C and 9 mm²/s at 100 °C, it indicates a lubrication profile with predictable flow behavior across different temperatures. Temperature resistance is stated up to +200 °C, providing flexibility in machining areas where localized heating can occur. A minimum shelf life of 24 months at room temperature is specified, helping with stock planning. Compatibility information with MIL-C-1258 under MIL-Spec is also provided.

Application method and correct use steps
For this technical spray, shaking the can thoroughly before use is recommended so the contents are sprayed homogeneously. Spraying generously from about 20–25 cm aims to ensure the cutting zone reaches a sufficient lubricating film. Applying a controlled top-up just before or during machining can improve efficiency, especially in tapping and drilling operations. If excessive build-up on the workpiece is not desired, the application amount should be adjusted gradually according to process needs.

Application areas, compatible surfaces, and operational advantages
Metalworking shops, mold and tool manufacturing, automotive suppliers, machinery manufacturing, and maintenance/repair teams are the main user groups for this type of technical spray. Thanks to its multi-material compatibility, it can help standardize on a single product in production environments working with different alloys. The clear and almost odorless character supports operator comfort and application control. Because it is a pressurized aerosol, it should be protected from direct sunlight in storage and not exposed to temperatures above +50 °C; during use, good ventilation and working away from ignition sources are basic safety measures.
