If your application requries heavy duty performance, consider our 0-80 HSS Nitro Bottom Tap. The Nitro line features a durable surface treatment that enhances hardness, making it ideal for materials such as cast iron and 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.
