3/8-24 HSS Nitro Bottom Tap

• 

If your application requries heavy duty performance, consider our 3/8-24 HSS Nitro Bottom Tap. The Nitro line features a tough surface treatment for increased hardness for working with materials such as cast iro or stainless steel. Bottom taps are specifically designed for threading near the bottom of blind holes, with minimal chamfer for maximum thread depth. Their specialized flute geometry evacuates chips from the blind hole during cutting, ensuring smooth operation.
