The use of a suitable lubricant is essential with most tapping and reaming operations. Recommended lubricants for some common materials are as follows:
Petroleum-based or synthetic cutting oil.
Petroleum-based cutting oil mixed with a small amount (approximately 10%) of kerosene or mineral spirits. This mixture is also suitable for use with stainless steel.
No lubricant. An air blast should be used to clear chips.
Kerosene or mineral spirits mixed with a small amount (15-25%) of petroleum-based cutting oil. WD-40 and 3-In-One Oil are acceptable substitutes in some cases.
Kerosene or mineral spirits.
Kerosene or mineral spirits mixed with a small amount (10-15%) of petroleum-based cutting oil.
